I think that was a C46 after an engine change. The Electra gear got fouled in the doors. As soon as they pulled the door off, it fell by gravity.
Edited, found the hammer incident and the Electra one: -
On 9 November 2012, BFL509, a Curtiss C-46A (C-GTXW), landed at Yellowknife Airport and when it rolled to the runway 16/34 intersection, the left main landing gear collapsed. The aircraft then came to rest on the left wing and suffered substantial damage. The aircraft was repaired and returned to service. The cause of the accident was that a hammer, lodged between the inboard drag strut and sliding member, caused the landing gear to collapse.
On 5 March 2012, BFL1105, a Lockheed L-188A Electra (C-FBAQ), landed at the Yellowknife Airport, but was unable to extend the right main landing gear. The aircraft landed on the left and nose gear and caused substantial damage to the number three and four propellers and wing. The five occupants on board were uninjured
