NTSB Identification: GAA17CA034
14 CFR Part 91: General Aviation
Accident occurred Sunday, October 23, 2016 in Tracy, CA
Probable Cause Approval Date: 03/13/2017
Aircraft: YAKOVLEV YAK, registration: N38YK
Injuries: 1 Uninjured.
NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The pilot of the high-performance airplane reported that, on his third simulated forced landing, while turning left base to final in a slip, he realized that the airplane was too low and not aligned with the runway. He applied full throttle to go around. The airplane responded suddenly by changing attitude but continued to descend and impacted terrain and the airport perimeter fence. The airplane sustained substantial damage to both wings and the fuselage.
The pilot further reported that the slow airspeed coupled with the unexpected high torque from advancing the throttle during an uncoordinated left turn were factors in the accident.
The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s unstabilized approach and delayed application of full throttle for a go-around, which resulted in an uncontrolled descent.
