Background Transport Canada, which is the aviation authority for Canada, has issued Canadian AD CF201816, dated June 14, 2018 Transport Canada AD
CF201816, to correct an unsafe condition for all serial-numbered Bell Model 206, 206A, 206A1, 206B, 206B
1, 206L, 206L1, 206L3, 206L4, 222, 222B, 222U, 230, 407, 427, 429 and 430
helicopters. Transport Canada advises that Bell delivered comfort clips with some helicopters, and that these comfort clips, which were also sold as spare parts or accessories, were intended to improve occupant comfort by reducing shoulder harness tension. However, Transport Canada advises the comfort clip may interfere with the shoulder harness inertia reel, preventing the harness from locking and resulting in

injury to the occupant during an emergency landing. To prevent this unsafe condition, Transport Canada AD
CF201816 requires, within 25 hours air time or 10 days, whichever occurs first, determining if the comfort clips are installed. If the comfort clips are installed, Transport Canada AD CF
201816 requires removing them from service within 100 hours air time or 30
days, whichever occurs first, and inspecting each shoulder harness seat belt for damage and replacing any shoulder harness seat belt that has damage that exceeds allowable limits before further flight. Transport Canada AD CF201816 also prohibits the installation of any comfort clip on any helicopter.
FAAs Determination These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with Canada, Transport Canada, its technical representative, has notified the FAA of the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that an unsafe condition is likely to exist or develop on other helicopters of the same type designs.
