| FAA Proposes AD for Tail Rotor Drive on Bell 206 Model Helicopters |
The FAA proposes to adopt a new airworthiness directive (AD) for all Bell Textron Canada Limited Model 206A, 206A-1 (OH-58A), 206B, 206B-1, 206L, 206L-1, 206L-3 and 206L-4 helicopters. This proposed AD was prompted by a loss of tail rotor drive due to a failure of an adhesively bonded joint between an adapter and a tube on one of the segmented tail rotor drive shaft (TRDS) assemblies.
This proposed AD would require the following:
- Determining if an affected TRDS is installed.
- Repetitively inspecting the bond line for damage.
- Repetitively performing a proof load test of the TRDS assembly.
- Depending on the results of the inspections or proof load tests, removing an affected TRDS from service.
Read the complete proposal here. The FAA is accepting comments on the proposed AD until Jan. 12, 2023. To comment, follow the directions listed in the proposed AD. |
