Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(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.
Unsafe condition
This AD was prompted by an accident involving failure of a TT strap, which resulted in the main rotor blade detaching from the main rotor head. The FAA is issuing this AD to address failure of a TT strap. The unsafe condition, if not addressed, could result in loss of a main rotor blade and subsequent loss of control of the helicopter.
Affected ADs
None.
