Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 429 helicopters. This proposed AD was prompted by reports of the sliding doors jamming when opened from the inside of the helicopter, due to the aft lower roller assembly disengaging from the aft lower rail. This proposed AD would require inspecting the lower aft bracket and rail cavity for contact marks and, depending on the findings, performing applicable corrective actions. This proposed AD would also require modifying the roller assembly configuration. The FAA is proposing this AD to address the unsafe condition on these products.
