Perimeter Flight PAG 640, a Metro II with 2 crew and 8 passengers, was on approach to runway 18 at Winnipeg after a flight from St. Theresa Point when the crew carried out a missed approach due to landing gear problems. The right main gear would not extend in the down and locked position. The crew attempted a landing with the right main gear up and possibly hoped to free the gear to extend, however, this was unsuccessful and they subsequently elected to land gear up on their second approach. The aircraft landed successfully on its belly and came to a stop on the runway. The aircraft landed between Taxiways P and Q and all 10 occupants were evacuated and were transported to the hospital as a precaution. There were no obvious injuries and there was no fire after landing. The aircraft sustained substantial damage to its propellers, flaps and aft belly area. Inspection by TSB indicated that the inboard right main landing gear door partially hung up on the wheel well structure, preventing the extension of the landing gear. The reason for the gear door interference is under investigation.
This aircraft was involved in an unsafe gear incident the previous day at Winnipeg.
FINDINGS AS TO CAUSES AND CONTRIBUTING FACTORS:
1. The right inboard landing gear door was incorrectly rigged, which reduced the clearance between the tire and gear door during gear extension. The mis-rigged landing gear door likely went unnoticed through four separate inspections.
2. The combined effect of the mis-rigged gear door, the installation of a new re-capped tire with large dimensions, growing free play in the gear door bushings/linkage arrangement, and air loading on the gear door reduced clearances sufficiently that the number three tire caught on a ledge on the inboard door skin, preventing the right main gear from extending.
