Airworthiness Directive · Amendment 39-19291 · Main rotor head
Airbus Helicopters
This AD applies to Airbus Helicopters Model SA-365C, SA-365C1, and SA-365C2 helicopters, certificated in any category.
We are adopting a new airworthiness directive (AD) Airbus Helicopters Model SA-365C, SA-365C1, and SA-365C2 helicopters. This AD requires establishing a life limit of 2,000 hours time-in-service (TIS) for the Starflex star/mast connecting bolt (bolt) and removing from service each bolt that exceeds its life limit. This AD is prompted by the discovery that the bolt's life limit was not included in helicopter maintenance records. The actions of this AD are intended to prevent an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
Before further flight:
(1) Remove from service any bolt part number (P/N) 365A31-1182-20, 365A31-1182-21, 365A31-1183-20, 365A31-1183-21, 365A31-1928-20, or 365A31-1143-20 that has accumulated 2,000 or more hours time-in-service (TIS), or any bolt for which the hours TIS is unknown. Thereafter, remove from service each bolt P/N 365A31-1182-20, 365A31-1182-21, 365A31-1183-20, 365A31-1183-21, 365A31-1928-20, or 365A31-1143-20 before accumulating 2,000 hours TIS.
(2) Remove from service any bolt with a P/N not listed in paragraph (e)(1) of this AD or for which the P/N is unknown.
(3) Create a component history card or equivalent record for each bolt P/N 365A31-1182-20, 365A31-1182-21, 365A31-1183-20, 365A31-1183-21, 365A31-1928-20, and 365A31-1143-20 and record a life limit of 2,000 hours TIS.
