Incident at FORT MCMURRAY AB (CYMM) (Aerodrome, runway or taxiway shutdown)

Summary

2005-04-15: AM 35, a Piper Navajo, had departed Fort McMurray for Fort Chipewyan but shortly after takeoff, the pilot advised ATC he could not retract his landing gear and was returning to Fort McMurray. No equipment was requested or required and the aircraft landed safely on Runway 25 at 1916Z. After landing, the aircraft was unable to leave the runway on it's own power. The aircraft was towed to the ramp and the runway was unusable for 10 minutes causing a delay to one other aircraft (C-FZHG). Normal operations were resumed at 1926Z.
2005-04-18: UPDATE Maintenance and Manufacturing reported that PA-31-350 C-FVGT suffered a bent anti-retraction solenoid pin. This is the solenoid and pin that prevents the landing gear selector handle from being selected 'Up' when the a/c is in ground mode. These pins sometimes get bent, but the pin is able to rotate and will still function. When a bent pin rotates into a certain position the solenoid cannot pull it back far enough and continues to block the gear handle as if still in ground mode. This is what occurred to C-FVGT. This part is behind the instrument panel and buried in a difficult area to inspect. A bent pin can exist and not be detected (a pin bent directly away from the inspector appears straight). The solenoid and pin was replaced 17 April 2005 and an SDR is being submitted by the company.
