On February 12, 1983, a Cessna 140 (registration N7G) was involved in an aviation accident near Iliamna, AK. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A heavily loaded ski-equipped aircraft aborted takeoff on a frozen lake, turned to avoid metal drums, and struck a snow-concealed boat dock, then rotated and slid to a stop.
Incident Overview
A ski-equipped aircraft was conducting a takeoff from a snow-covered frozen lake. The pilot, recognizing that the heavily loaded aircraft was not accelerating sufficiently, aborted the takeoff attempt.
Sequence of Events
During the aborted takeoff, the pilot turned left to avoid metal drums that were in the path. However, after the turn, the aircraft collided with a boat dock that had been hidden beneath the snow. The impact caused the aircraft to rotate 180 degrees, and it subsequently slid to a stop.
Aftermath
The aircraft came to rest after the 180-degree rotation. No further details about the extent of damage or any injuries are provided in the source.
