She attempted to apply full throttle, but the engine did not respond. Unable to reach the runway, and in an effort to avoid rocks and debris on a nearby beach, she elected to land on adjacent mud flats. During the landing, the airplane nosed over and came to rest inverted. The instructor and student were able to egress the airplane, but the wreckage could not be secured before it was washed into the bay during rising tides. Due to the wreckage not being recovered, the reason for the power loss could not be determined. ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Approach-VFR pattern base: Loss of engine power (partial)](https://openairdocs.org/ntsb-events/342) (defining event) ## Aircraft - Registration: [N927AP](https://openairdocs.org/deregistered/N927AP-2023-05-21), registration cancelled 2023-05-21, S/N F-109, built 1978 (OpenAirDocs) - Reported make and model: TAYLORCRAFT AVIATION CORP F19 - Registry model: [Taylorcraft F19](https://openairdocs.org/model/taylorcraft-f19) (registry code 8850904) (OpenAirDocs) - Registry engine: [Continental O-200A](https://openairdocs.org/engine/continental-o-200a) (registry code 17404, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: F-109 - Year built: 1978 - Airframe hours: 3853.1 - Engines: Continental O-200-A66B 100 hp reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Special, Restricted (Special); Standard, Normal - Last inspection: Annual, September 4, 2021 - Departed: PANC, Anchorage, AK - Destination: Same as departure - Airport: Z40, Goose Bay, runway 26, 3,000 × 75 ft, gravel - Equipment: Unknown ## Flight crew As NTSB recorded them.
