Probable cause

The pilot’s decision to operate with a demonstrated crosswind velocity above the airplane’s performance capabilities which resulted in a loss of airplane control and collision with terrain.

Findings · 3

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, before his departure, he recorded the airport’s automated weather report as wind from 220° at 15 kts gusting to 21 kts. He then elected to perform the takeoff from runway 32 as runway 21 was too short for his performance needs. During takeoff he found it difficult to hold the runway centerline with full right rudder and even had to apply some right brake. The rudder control improved as his airspeed increased and the pilot was able to successfully transition the airplane into the initial climb. After the airplane lifted off the ground, the pilot was forced to place the airplane in a crab angle to counteract the wind. The pilot felt comfortable at this point and chose to continue with the departure; however, almost instantaneously the airplane descended and bounced and came to rest in dirt. The right wing was substantially damaged. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The automated weather report released about 30 minutes after the accident revealed that the airport was impacted by a peak wind from 250° at 26 kts that occurred at the time of the accident, which translated to a crosswind component of about 24 kts. The maximum demonstrated crosswind velocity for the airplane was 16 kts.
