Update on the WestJet 737 that suffered a gear collapse a few months.
TSB says the landing was not a hard landing event.
TSB discovered a cracked component in part of the landing gear.
I guess the inference here is it was mechanical failure rather than a hard landing that caused the landing gear to fail.
From the website:
Work completed as of October 2025
The initial review of the flight data recorder data indicates that this was not a hard landing event.
During the aircraft examination, the right gear aft trunnion pin was found fractured. The two portions of the aft trunnion pin were sent to the TSB Engineering Laboratory in Ottawa, Ontario, and are awaiting further examination.
The right main landing gear was overhauled in 2016.
The TSB is reviewing previous occurrences involving aft trunnion pin fractures on Boeing 737 aircraft.
