CA
Aircraft: ERCOUPE 415-D, registration: N2332H
Injuries: 1 Uninjured.
This is preliminary information, subject to change, and may contain errors. Any
errors in this report will be corrected when the final report has been
completed.
On January 14, 2010, at 1440 Pacific standard time, a Ercoupe 415-D, N2332H,
experienced a loss of engine power after takeoff and landed in a field off the
end of runway 36R at Napa County Airport, Napa, California. The commercial pilot
operated the airplane under the provisions of Title 14 Code of Federal
Regulations, Part 91. The pilot was uninjured and the airplane was substantially
damaged. Visual meteorological conditions prevailed, and a flight plan had not
been filed.
The pilot reported to the Safety Board investigator that both wing fuel tanks
were full and the engine run up was normal. Almost immediately after takeoff the
engine began to lose power, surged two times, then lost all power. The pilot
landed in an open field off the end of the runway. During the landing the nose
wheel sank into the soft ground and collapsed.

Accident occurred Wednesday, November 11, 2009 in Napa, CA
Probable Cause Approval Date: 3/3/2010
Aircraft: CAMERON BALLOONS US A-250, registration: N4062M
Injuries: 1 Serious, 12 Uninjured.
The pilot of the balloon reported that after three unsuccessful landing attempts
during the sightseeing flight, he located a grassy 2-3 acre field and positioned
the balloon for landing. He stated that the approach was from the northwest at
500-feet and the balloon was traveling about 6 knots. The pilot anticipated
winds near the surface to be from the east; however, after descending to
250-feet the balloon continued in a southerly direction, near trees. The pilot
executed a controlled descent over a tree and landed firmly. The basket bounced
once and came to rest upright with the balloon's envelope against a tree. After
the landing, one of the passengers complained of ankle pain and was transported
to a hospital. A medical evaluation revealed that the passenger's ankle was
fractured. The pilot reported that a passenger landing briefing was completed
prior to landing.

On August 05, 2009, at 0431 Pacific daylight time, a Cessna 182S, N23750,
impacted a hill shortly after departing from Napa County Airport, Napa,
California. Sierra Madre Corp. was operating the airplane under the provisions
of 14 CFR Part 91. The commercial pilot, the sole occupant, was killed. The
airplane was substantially damaged. The cross-country personal flight was
originating from Napa with a planned stop in Bakersfield, California, and final
destination of Santa Fe, New Mexico. Instrument meteorological conditions
prevailed in the area surrounding the accident site. An instrument flight rules
(IFR) flight plan had been filed and a clearance had been issued; the flight
plan was never activated.
During a telephone conversation with a Safety Board investigator, the pilot's
spouse recalled that they had been planning a trip down to New Mexico. As for
the trip's logistics, she stated that she was a timid flyer, and therefore,
opted to take a commercial flight. Her husband planned to fly the accident
airplane, which he was a partial owner. He had flown the airplane on this route
about 5 times prior and liked to leave early to avoid any weather. For this
flight he planned to land in Bakersfield to refuel and then continue on to Santa
Fe, where he would meet his wife later on in the day.
The pilot's spouse further stated that after leaving their residence in the San
Francisco area, he called her about 0315 reporting that the weather was good. He
again telephoned her around 0400 stating that he was at the airplane hangar and
preparing to depart.
The pilot received an IFR clearance and correctly read back the following, "BFL
from APC via LIZRD3 departure, CROIT transition V108 LIN V23 EHF BFL."
Preliminary recorded radar data covering the area of the accident was supplied
by the Federal Aviation Administration (FAA) in the form of a National Track
Analysis Program (NTAP) printout from Oakland Air Route Traffic Control Center
(ARTCC). The radar data was analyzed for time frame and proximity to the
anticipated flight track of the airplane en route as dictated in the pilot's IFR
clearance.
The radar data consisted of approximately equidistant radar returns from 0429:17
to 0430:54. The data was consistent with the airplane making a shallow left bank
and gradually increasing in altitude towards the east. The target was first
identified at a Mode C reported altitude of 100 feet mean sea level (msl).
During the proceeding minute, radar returns disclosed a gradual ascent to 1,000
feet msl. The last two returns show an altitude of 900 feet and a slight change
of direction to the south. The last radar return was located about 0.5 miles
north of the accident site.
A routine aviation weather report (METAR) generated by an Automated Surface
Observation System (ASOS) in Napa reported that at 0354 there was a broken cloud
layer at 600 feet above ground level (agl) with 10 miles visibility. It recorded
the temperature at 55 degrees Fahrenheit; dew point 54 degrees Fahrenheit. An
updated weather report at 0454 additionally reported a broken cloud layer at 600
feet agl with no temperature/dew point spread.
The Nation Weather Service facility in Monterey, California, provided the
archived weather information of the Napa ASOS at the time nearest to the
accident (given with 5 minutes between observations). The information disclosed
that at 0430 there was an overcast cloud layer at 600 feet agl with 10 miles
visibility. It recorded the temperature at 55 degrees Fahrenheit; dew point 55
degrees Fahrenheit.
The accident site was located in the Napa Valley hills about 3.25 nautical miles
(nm) southeast of the departure end of runway 18R at Napa. The main wreckage was
located at an estimated 38 degrees 11.429 minutes north latitude and 122 degrees
14.133 minutes west longitude, at an elevation of about 313 feet msl.
The main wreckage came to rest at the edge of a vineyard, with the inboard
section of the left wing and tail section near remnants of the burned fuselage.
Fragments of the airplane's wheel pants were the farthest debris found from the
main wreckage; they were located downslope about 250 feet on a median magnetic
bearing of about 345 degrees. All control surfaces were accounted for at the
accident site.
The wreckage was recovered to a secure location for further examination.

Accident occurred Saturday, November 10, 2007 in
Napa, CA
Probable Cause Approval Date: 12/20/2007
Aircraft: Piper PA-34-200T, registration: N3038P
Injuries: 1 Uninjured.
The pilot stated he unloaded his passengers at
the FBO and was returning to his home airport. He noted he had been distracted
during the unloading and pre takeoff phases, and neglected to latch the front
cargo door. During takeoff, the forward nose cargo door opened and the pilot
decided to abort the takeoff. He opined that the wet runway caused the airplane
to hydroplane, which made stopping difficult. The airplane overran the end of
the runway, continued about 200 yards, collided with a fence, and came to rest
in a canal. The pilot reported no preimpact mechanical malfunctions or failures
with the airframe or engine. The National Transportation Safety Board determines
the probable cause(s) of this accident as follows: The pilot's failure to latch
the cargo door during preflight. ===
Accident occurred Monday, May 28, 2007 in Napa,
CA
Probable Cause Approval Date: 4/30/2008
Aircraft: Cessna TU206G, registration: N7395C
Injuries: 2 Minor, 1 Uninjured.
Shortly after takeoff, a loud noise was heard in
the cockpit followed by severe engine vibrations. The pilot knew he was not
going to be able to make it back to the airport and made a forced landing in an
open salt marsh 3.5 miles southwest of the closest airport. During the landing
rollout, the landing gear dug into the soft ground and the airplane nosed over
and came to rest inverted. Visual inspection of the airframe revealed no traces
of oil on the belly. During the visual inspection of the engine, the
turbocharger was found oil soaked, and the number 5 cylinder contained a
circular crack around the head with a red discoloration of the top portions of
the cylinder fins. The engine was disassembled and investigators noted that the
number 5 connecting rod had separated at the crankshaft rod journal. A high
pressure air source was utilized to check for blockage of the oil galleys and
passages. Investigators noted that the number 5 crankshaft rod journal oil port
was blocked with smeared metal; there were no additional blockages found. About
2 to 3 quarts of oil were drained from the oil sump, along with portions of the
number 5 connecting rod, pieces of piston and piston rings, and the intake and
exhaust lifters for the number 5 cylinder. The National Transportation Safety
Board determines the probable cause(s) of this accident as follows: Failure of
the number 5 connecting rod due to oil starvation. ===
Accident occurred Wednesday, July 26, 2006 in
Napa, CA
Probable Cause Approval Date: 11/29/2006
Aircraft: Cessna 150J, registration: N60816
Injuries: 1 Minor.
The airplane lost engine power and nosed over
during a forced landing. The pilot performed a preflight inspection of the
airplane and checked the fuel quantity in each wing tank using a fuel measuring
stick. He reported that there was no fuel in the left fuel tank, and 5.5 gallons
of usable fuel in the right fuel tank. The pilot stated that he had more than
enough fuel for the expected 19-minute flight. He performed an engine run-up and
executed a normal takeoff. After clearing the mountains west of the departure
airport, he radioed the air traffic control tower at the destination airport and
requested a special visual flight rules (SVFR) clearance for runway 18. The
controller told the pilot to remain outside the class delta airspace and to
expect a 10-minute delay for landing. The pilot remained outside the airspace by
maneuvering in right circles over a landmark. The pilot said that at this point,
the fuel in the right tank lost contact with the fuel pickup port and the engine
lost power. The pilot could not make it to the airport from his location and
chose to land in a field approximately 5 miles north of the airport. The pilot
successfully landed in the field; however, when the nose wheel touched down it
dug into the soil and the airplane nosed over. A Federal Aviation Administration
inspector examined the airplane on scene and reported that he found no fuel in
the left fuel tank and no more than 6 gallons of fuel in the right fuel tank.
The National Transportation Safety Board determines the probable cause(s) of
this accident as follows: a loss of engine power due to fuel starvation. The
fuel starvation was the result of the pilot's inadequate preflight preparation
(failure to refuel the airplane before taking off) and his inadequate in-flight
decision (to make right turns while holding) that directly led to an unporting
of the right fuel tank. ===
Accident occurred Thursday, March 11, 2004 in
Napa, CA
Probable Cause Approval Date: 9/14/2007
Aircraft: Mitsubishi MU-2B-40, registration:
N966MA
Injuries: 2 Fatal.
The airplane entered a descending turn while on
a night visual approach and impacted a river. At 2030, the pilot reported
leaving 6,000 feet, and stated that he had the airport in sight. The controller
cleared him for the approach. He advised the controller that he would like to
cancel his IFR clearance, and switch to the traffic advisory frequency. The
controller cleared him to switch to advisory frequency. No further transmissions
were recorded from the flight. According to radar data, the airplane was
southeast of the airport, and maintaining a westerly heading south of the
airport. At 2035, it crossed a river, and began a sharp left turn away from the
airport. It completed about 90 degrees of turn before abruptly disappearing from
radar contact, with the last radar target on the west side of the river near the
impact location. The highly fragmented wreckage was recovered from the river
after several weeks underwater. The teardown and examination of the engines
disclosed that the left engine was not rotating or operating at the time of
impact, and the left propeller was in feather. The type and degree of damage to
the right engine was indicative of engine rotation and operation at the time of
impact. Investigators found no pre-existing condition on either engine, or with
the airframe systems, that would have interfered with normal operation, or
explained the apparent shutdown of the left engine. The National Transportation
Safety Board determines the probable cause(s) of this accident as follows: The
pilot's failure to maintain control of the airplane following a shutdown of the
left engine during a night visual approach. A factor contributing to the
accident was the dark night. ===
Accident occurred Wednesday, April 30, 2003 in
Napa, CA
Probable Cause Approval Date: 3/30/2005
Aircraft: Eurocopter France AS350B3,
registration: N341HP
Injuries: 3 Uninjured.
The pilot made a forced landing after the
helicopter experienced an engine over speed and subsequent engine fire when
recovering from a practice autorotation. At 600 feet and 80 knots the pilot
under instruction (PUI) entered the practice autorotation after the certified
flight instructor (CFI) rolled the collective twist grip to idle to simulate an
engine failure. The PUI executed the practice autorotation towards the runway.
During the recovery sequence the PUI inadvertently and unknowingly engaged the
manual fuel control slide lock on his collective as he adjusted the collective
for a power recovery, allowing the CFI to twist the collective grip past the
"VOL" (fly) position. The engine and rotor RPM oversped due to excessive fuel
flow to the engine, which resulted in a catastrophic failure of the turbine
section. The airport tower notified the crew that the helicopter was on fire.
The crew made a force landing on the runway, egressed, and fire crews arrived to
extinguish the fire. The collective twist grip has two normal operating
positions. The "MIN" position sets the engine at idle, while turning the grip
counter clockwise to the "VOL" (flight) position stop accelerates the engine to
a flight rpm setting. At the "VOL" position the DECU (Digital Engine Control
Unit) controls the engine power to maintain rpm as the pilot moves the
collective. A slide lock device prevents the twist grip from moving beyond the
"VOL" position. The manual fuel control slide lock is only on the right pilot
seat collective. The twist grip can be moved beyond the "VOL" position by moving
a slide lock lever on the collective twist grip forward and rotating the twist
grip beyond the "VOL" position. Once the twist grip is out of the "VOL" detent
position the pilot input has priority over the DECU and the pilot is manually
metering fuel to the engine; this could allow the pilot to increase the amount
of fuel delivered to the engine beyond what the DECU is delivering. The slide
lock is spring loaded to its retracted locked position unless moved forward,
usually by the pilots thumb, approximately 5 mm. At this point it is then
"latched" open allowing the twist grip to be rotated beyond the "VOL" position.
Post accident examination and testing of the engine fuel control unit and the
manual slide lock mechanism found no preimpact mechanical malfunctions or
failures. The helicopter manufacturer is aware of four prior inadvertent manual
throttle activations that resulted in engine overspeed conditions and damage to
both the engines and airframe structures. The manufacturer has discontinued
installing the twist grip mechanical flight stop device and replaced it with an
electrical solenoid type of configuration on all production AS350-B3
helicopters. This new configuration is also available to current owners and
operators as a hardware modification. The National Transportation Safety Board
determines the probable cause(s) of this accident as follows: the pilot under
instruction's inadvertent activation of the collective manual fuel slide lock,
which led to engine and main rotor overspeeds due to excessive fuel flow during
power application. This resulted in failures of the gas generator turbine (N1)
blades, power turbine (N2) blades, and created an external engine fire. A factor
in the accident was the manufacturer's inadequate design of the twist grip slide
lock, which had insufficient safeguards to preclude inadvertent activation. ===
Accident occurred Saturday, November 16, 2002 in
Napa, CA
Probable Cause Approval Date: 12/28/2004
Aircraft: Bellanca 14-19, registration: N501A
Injuries: 1 Uninjured.
The engine lost power during a missed instrument
approach, and the pilot had to ditch the airplane. The airplane came to rest
inverted and sank. The flight originally departed a Southern California airport
at 0715 on a flight to Napa. The pilot stated that he departed with full fuel
tanks consisting of 40 gallons in the main wing tanks (a 20-gallon tank in each
wing) and 14 gallons in the auxiliary tank. The pilot did not detect any
problems with the airplane during the flight. Upon arriving in the vicinity of
Napa he learned that the weather was below IFR minimums. He diverted to Angwin
to wait for the weather to improve and landed about 0915. After the Napa weather
improved, the pilot departed Angwin at 1030. The pilot said he did not refuel at
Angwin and he determined that he had about 30 total gallons of fuel onboard. The
pilot received an IFR clearance upon approaching APC. During the localizer
approach into runway 36L, he was advised that he was too high and to execute a
missed approach. As the flight began the missed approach, the controller issued
a holding clearance and the pilot stated "...fuel's getting low..." as a result,
the controller issued vectors to intercept the localizer into APC. During climb
out, between 2,500 to 3,000 feet, the engine began to lose power. The pilot
requested immediate vectors to APC. During this time, the pilot performed
emergency operations: switching fuel tanks, engaging carburetor heat, checking
mixture control, and engaging the fuel boost pump. This momentarily restored
power, and the pilot advised the approach controller; however, within a few
moments the engine again lost partial power. The engine completely lost engine
power shortly thereafter. The pilot broke out of the cloud layer and was
approximately 200 feet above ground level (agl) and found only water below him.
The pilot advised the controller that he would be landing in the water and then
executed a "slow, stalled landing." The aircraft came to rest inverted. The
pilot freed himself from the airplane, and a passing fishing boat rescued him. A
FAA inspector examined the airplane and found no evidence of damage or a
malfunction that would have caused the engine to stop running. The FAA inspector
was unable to determine if there had been fuel on board the airplane at the time
of the accident due to water in the airplane's fuel system. Water was also in
all of the airplane's systems. According to information provided by Textron
Lycoming, the O-435-A engine's typical fuel consumption is 12 to 14 gallons per
hour at 60 percent power, and 16 to 18 gallons per hour at 70 percent power. A
carburetor icing chart indicated serious icing conditions were favorable during
the time of the accident. The National Transportation Safety Board determines
the probable cause(s) of this accident as follows: the pilot's inadequate
management of the fuel system, which led to fuel starvation and a water
ditching. ===
Accident occurred Monday, June 25, 2001 in Napa,
CA
Probable Cause Approval Date: 11/28/2001
Aircraft: Cessna 172M, registration: N1409V
Injuries: 2 Uninjured.
During the missed approach the engine lost
power, was maneuvered to land, and came to rest inverted after the nose wheel
touched down in soft dirt. The purpose of the flight was to conduct instrument
training at local area airports. The flight had departed home base approximately
an hour away from the accident airport. No discrepancies were noted with the
engine during the flight or the approach to land. As the student reached MDA the
CFI instructed the student to conduct the missed approach. They climbed straight
ahead to 500 feet msl and initiated a left-hand turn for compliance with the
missed approach procedure. The engine began to lose power. The CFI declared an
emergency and conducted the emergency checklist. She turned towards the runway
and slipped the airplane down land on the runway. Due to the altitude, she knew
they would not make the runway, so she attempted to land in a grassy area past
the departure end of the runway. Again, the airplane was too high for landing
and she had to maneuver to avoid the airport perimeter fence. The CFI turned
away from the fence. When she returned the airplane to wings level flight the
wheels touched down. The nose wheel dug into the soft dirt and the airplane
flipped over. Examination of the engine revealed that the exhaust push rod
housing and exhaust push rod were bent. The crankshaft was manually rotated
establishing valve training continuity. No further discrepancies were noted with
the engine. The National Transportation Safety Board determines the probable
cause(s) of this accident as follows: Loss of engine power due to the restricted
movement of the number 1 exhaust valve that subsequently bent the exhaust push
rod and push rod housing. ===
Accident occurred Sunday, May 06, 2001 in NAPA,

Probable Cause Approval Date: 11/28/2001
Aircraft: Piper PA-24-260, registration: N8710P
Injuries: 4 Uninjured.
During a forced landing due to a loss of engine
power on climb following a touch-and-go, the airplane touched down near the end
of the runway, rolled across a field, struck a fence, and stopped in a ditch.
The airplane departed 35 minutes earlier with main fuel tanks indicating half
full and auxiliary fuel tanks indicating full. The pilot did not verify the
indications of the fuel quantity gauges. In the accident type of airplane,
takeoffs and landings must be performed with fuel being drawn from the main fuel
tanks. The National Transportation Safety Board determines the probable cause(s)
of this accident as follows: The pilot-in-command's failure to verify the fuel
supply before flight, and his improper fuel management, that resulted in fuel
starvation and loss of engine power during takeoff climb resulting in a forced
landing and collision with ground obstacles. ===
Accident occurred Sunday, January 30, 2000 in
NAPA, CA
Probable Cause Approval Date: 10/9/2001
Aircraft: Siai-Marchetti SF260, registration:
N65FD
Injuries: 2 Uninjured.
The pilot planned a nonstop flight from Phoenix,
Arizona, to Napa, California. Approaching Napa, he realized that his airplane
was low on fuel, but he did not so advise control tower personnel. The pilot
entered the traffic pattern and while on base leg experienced fuel exhaustion.
Unable to glide to the airport, the airplane came to rest in a rough field about
300 yards short of the runway. The National Transportation Safety Board
determines the probable cause(s) of this accident as follows: Fuel exhaustion
due to the pilot's inadequate en route fuel consumption calculations.
