Aviation Accident Summary GAA17CA341

Galena, ID, USA

Aircraft #1

N9912Q

CESSNA 172

Analysis

The pilot reported that he was attempting to perform a crosswind, soft-field takeoff from a dry, turf airstrip. He set the flaps to 10°, and the airplane was in a nose-high attitude until the stall warning horn sounded. He then relaxed pressure on the yoke until the stall warning horn stopped. Shortly after liftoff, the airplane entered a power-on stall, and the pilot lost airplane control, and the airplane then began to descend to the runway. The airplane subsequently departed the runway and impacted a barbed wire fence. The airplane sustained substantial damage to the right wing strut. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual Information

The pilot in the airplane reported that he attempted to perform a crosswind, soft-field take off from a dry turf airstrip. The pilot configured the airplane with full throttle application, flaps 10°, and a nose high attitude until the stall warning horn sounded. He then relaxed pressure on the yoke until the stall warning horn subsided. Shortly after rotation the airplane entered a power-on stall and the pilot lost directional control of the airplane. The airplane impacted a barbed wire fence and sustained substantial damage to the right wing strut. Per the National Transportation Safety Board Pilot Aircraft Accident Report, the pilot reported that the accident could have been prevented, if he had received instruction from a Federal Aviation Administration Certificated Flight Instructor that was specific to the accident airplane, specifically for a soft-field takeoff because each individual aircraft has nuances that can affect the operation. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The pilot's exceedance of the airplane’s critical angle of attack, which resulted in a power-on stall and subsequent loss of airplane control.
