The FAA is adopting a new airworthiness directive (AD) for Bell Textron Inc. Model 204B, 205A, 205A-1, 205B, 210, and 212 helicopters and various restricted category helicopters with certain part-numbered tension torsion (TT) straps installed by supplemental type certificate (STC) No. SR03408CH. This AD was prompted by an accident involving failure of a TT strap. This AD requires removing the specified part-numbered TT straps from service and prohibits installing those TT straps. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Remove the TT straps from service and replace them with airworthy TT straps at the compliance time required by paragraphs (g)(1)(i) or (ii) of this AD, as applicable.
(i) For TT straps that as of the effective date of this AD have accumulated 350 or more total hours time-in-service (TIS) since first installation on any helicopter, within 50 hours TIS after the effective date of this AD.
(ii) For TT straps that as of the effective date of this AD have accumulated less than 350 total hours TIS since first installation on any helicopter, before the TT straps accumulate 400 total hours TIS since first installation on any helicopter.
(2) As of the effective date of this AD, do not install the TT straps identified in the introductory text of paragraph (c) of this AD on any helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
