Location: Galena, ID
Accident Number: GAA17CA341
Date & Time: 06/14/2017, 1100 MDT
Registration: N9912Q
Aircraft: CESSNA 172
Aircraft Damage: Substantial
Defining Event: Abrupt maneuver
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal
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.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
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.
Findings
Aircraft
Pitch control - Not attained/maintained (Cause)
Personnel issues
Aircraft control - Pilot (Cause)
Environmental issues
Fence/fence post - Contributed to outcome

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.
