Narrative:A de Havilland Canada DHC-8-301 passenger plane, operating as Bahamasair flight UP-353, sustained substantial damage in a landing accident at Governor's Harbour Airport (GHB), Bahamas. There were no injuries among the 51 occupants.
The airplane landed on runway 15 at Governor's Harbour following a flight from Nassau. On touchdown the left hand main landing gear separated. The airplane skidded and came to rest on the runway.
Probable Cause has been determined as an over-center Torque Link condition that culminated in a single cycle failure of the cylinder. The over center torque links condition occur as a result of the over extension of the shock strut.
Possible Contributory factors to the over extension of the shock strut includes:
Possible Cause for Loss of Damping
- The failure to install the dampening ring when the landing gear was assembled.
- Improper servicing of the landing gear shock strut with Mil-H-5606 hydraulic fluid plus nitrogen during initial assembly.
- Improper servicing of landing gear shock strut during line maintenance and inadequate post servicing follow up per AMM Chapter 12. See attached report Appendix A-30 From Bombardier
- Under-serviced shock strut (low oil volume)
- A broken damper ring
- No damper ring
- Disengaged damper ring
