An aircraft crashed on Somerset Island after its left ski struck the ground short of the runway in whiteout conditions. The ski was torn off, and the aircraft was damaged beyond repair. Both pilots were unharmed.

Accident Summary

An aircraft conducting an approach to Somerset Island encountered whiteout conditions. On short final, the crew failed to realize their altitude was too low. The left ski struck the ground approximately 150 feet short of the runway threshold, digging into the snow and tearing off. The resulting loss of control caused the aircraft to crash. Both pilots escaped uninjured, but the aircraft sustained damage beyond repair.

Investigation and Findings

The official investigation determined that the probable cause of the accident was the crew's decision to attempt a landing in below-minima visibility due to the whiteout conditions. The whiteout environment severely reduced visual cues, leading to an undetected descent below the intended approach path.

Aftermath

The wreckage was later convoyed to the Calgary Air Museum, where it remains as a historical artifact.
