PAG Flight 640: Swearingen SA226-TC Metro II Gear-Up Landing at Winnipeg

Winnipeg, Manitoba, CA

On March 3, 2009, a Swearingen SA226-TC Metro II C-FSLZ operated by Perimeter Aviation Ltd. was involved in an aviation accident near Winnipeg, Manitoba, CA. Investigators recorded the probable cause as: The combined effect of a mis-rigged right inboard landing 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… This summary draws on records from the Transportation Safety Board of Canada (TSB).

PAG Flight 640, a Swearingen SA226-TC Metro II (C-FSLZ), made a gear-up landing at Winnipeg after the right main gear failed to extend due to tire and gear door interference. No injuries were reported.

Incident Overview and Emergency Response On the day of the accident, Perimeter Aviation Limited operated Flight 640, a Swearingen SA226-TC Metro II with registration C-FSLZ and serial number TC-222EE, from St. Theresa Point, Manitoba, to Winnipeg/James Armstrong Richardson International Airport. The aircraft carried two crew members and eight passengers. During the final approach to Winnipeg, the crew selected the landing gear down. While the nose and left main gear indicated down and locked, the right main gear remained in transit. The crew executed a missed approach, declared an emergency, and entered a holding pattern to attempt further gear extension. Both normal and emergency extension methods failed to deploy the right main gear. Observations from the cabin indicated the right main gear was hung up in the wheel well with the gear doors partially open, and the inboard tire was resting on the inboard gear door. The crew elected to perform a gear-up landing into the wind on Runway 18, with aircraft rescue and firefighting personnel standing by. Over the runway threshold, the crew shut down both engines and feathered both propellers. The aircraft came to a gradual stop on its belly on the runway centerline at 1209 central standard time. All occupants evacuated the aircraft with no injuries reported. The aircraft sustained substantial damage to its propellers, flaps, and aft belly area.

Probable cause

The combined effect of a mis-rigged right inboard landing 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.
