NTSB Identification: GAA16CA264
14 CFR Part 91: General Aviation
Accident occurred Saturday, May 21, 2016 in Seward, AK
Probable Cause Approval Date: 08/03/2016
Aircraft: PIPER PA18, registration: N1258C
Injuries: 2 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 flight instructor reported that during an instructional flight, while on short final, the headwind dissipated and the airplane started to slow and sink. He instructed the pilot receiving instruction in the front seat to add power, but she did not complete the action immediately. After realizing the action was not complete the flight instructor added full power, but the airplane continued to descend at an accelerated rate and touched down hard upon landing. Subsequently, the main landing gear collapsed and the fuselage was substantially damaged.
The flight instructor did not report any 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 receiving instruction's failure to maintain proper airspeed and descent rate, and the flight instructor's delayed remedial action during the landing flare, which resulted in a hard landing and landing gear collapse.
