As the axle sustained some damage, the landing gear assembly along with the brake units and wheel assemblies were replaced before returning the aircraft to service. The main wheel assembly has been recovered. On January 4, 2020, another aircraft (C-GABO) suffered a No. 3 main wheel bearing failure while taxiing to the gate. Due to the failures on these aircraft, a fleet campaign was commenced on the DHC classic fleet (All DHC-8-102/301/311) to inspect and report on the condition of the main wheel bearings. A Safety Management System (SMS) investigation is currently underway. Further updates on the results of the campaign and SMS investigation will be made in Continuing Airworthiness Web Information System (CAWIS) as part of the follow-up on the two Service Difficulty Reports (SDRs) submitted by the operator.
