Airport Area Accident History:
Accident occurred Friday, July 23, 2004 in
Mendota, CA
Probable Cause Approval Date: 6/8/2005
Aircraft:
Air Tractor AT-502B, registration: N5010E
Injuries: 1 Uninjured.
The airplane collided with high vegetation and
terrain during the initial climb from a dirt
airstrip on an agricultural application flight.
Prior to takeoff, the pilot failed to lower the
wing flaps to the 10-degree setting that he had
utilized on his previous takeoffs from the
airstrip. While on the takeoff roll, the pilot
realized that he had not configured the airplane
with the flap setting he was accustomed to
using, and he attempted to extend the flaps.
Despite his attempts, the flaps remained in the
retracted position for undetermined reasons.
With about 20 feet of runway remaining, the
pilot attempted to release the load. However, he
tried but failed to deploy the cargo dump
handle. The airplane lifted off the runway but
was unable to gain enough altitude to clear the
nearby 5- to 6-foot-tall corn crop. After
impacting the corn, the airplane stalled,
impacted the ground, and cartwheeled three times
before coming to a stop inverted.
The National Transportation Safety Board
determines the probable cause(s) of this
accident as follows:
The pilot's inadequate preflight/pretakeoff
procedure by not lowering the wing flaps, which
resulted in an inadvertent stall as the pilot
attempted to climb out of
ground effect to clear a corn crop at the
end of the runway. A factor in the accident was
the failure, for undetermined reasons, of the
flaps to deploy during the takeoff roll when the
pilot moved the switch.
