Incident at CALGARY INTL AB (CYYC) (Aerodrome, runway or taxiway shutdown)

Summary

2003-06-03: C-FCCM, a PA-30 Twin Comanche, was on a VFR training flight at Calgary with an instructor and student. The pilot initially reported an unsafe gear indication over Springbank, but managed to get a three green indication. During the landing on Runway 34 at Calgary, the right main gear began to collapse and the pilot safely rejected the landing and got airborne. He attempted to rectify the problem but was unable and during the landing on Runway 25, the right main gear collapsed. The a/c came to a stop on the north side of the runway clear of the other runways and taxiways. There were minor delays to other a/c. The a/c has subsequently been removed from the runway. TSB has been in touch with the company.
2003-06-05: UPDATE TSB reported that the Morgan Air Services Piper PA-30, C-FCCM, was performing a training flight with an instructor and student on board. During circuits in Springbank, AB, the landing gear motor circuit breaker tripped. The alternate gear extension procedure was performed resulting in a gear down and locked indication in the cockpit. The PA-30 returned to Calgary and during touchdown, the instructor perceived the right gear collapsing and commenced a missed approach before the propeller could strike the runway surface. ATC personnel in the Tower observed that the right main gear was partially retracted. The PA-30 circled east of the airport for two hours trying to trouble shoot the problem. Another approach was attempted in Calgary with a gear down and locked indication, and the right main gear collapsed on touchdown. The aircraft received minor damage to the right-hand flap and wing skins. The operator will be submitting an SDR to Transport Canada.
2003-06-04: UPDATE Maintenance and Manufacturing reported that the RH main gear conduit flexible outer sleeve moved with the inner cable, exposing 11"" of inner cable. The inner cable then looped out of the exposed area. Now with the cable being bent, the RH gear could not extend over center for down and locked. M. & M. advised the company to submit an SDR on the failure of the cable as required by CAR 591. The damge to the a/c was limited to an aileron/flap and a rib replacement in the gear well. There was not a prop strike as the pilot had feathered that prop prior to the collapse. Consequently, this occurrence has been classified as an incident rather than an accident.
