(2) For a pilot cyclic stick tube assembly that has accumulated 3,600 or more hours time-in-service if, after complying with paragraph (g)(1) of this AD, no cracks are identified, thereafter, at intervals not to exceed 300 hours time-in-service or 6 months, whichever occurs first, perform a detailed inspection of the pilot cyclic stick tube assembly in accordance with Part II paragraph A. of Transport Canada AD CF-2024-18.
Unsafe condition
This AD was prompted by a report of a fractured pilot cyclic stick tube and subsequent findings of other pilot cyclic stick tubes with fatigue cracking. The FAA is issuing this AD to detect and correct a crack in the pilot cyclic stick tube which, if not addressed, could lead to an in-flight failure of the pilot cyclic stick tube and consequent loss of control of the helicopter.
Affected ADs
None.
