What happened
Following takeoff, the pilot retracted the landing gear and observed that while the main gear lights went out, the gear light remained illuminated. The pilot attempted to cycle the gear, but the same indication persisted. The pilot then selected the gear down and returned for a landing, at which point the cockpit displayed a three green indication.
During the landing roll, the nose gear collapsed. There were no injuries reported.
The investigation
The investigation found no evidence of a mechanical failure or malfunction within the landing gear system. However, a mechanic noted that due to extreme low temperature conditions, the nose gear actuator may have frozen, preventing the gear from completing its full range of travel between the up lock and down lock positions.
