4directives reference this part number — recurring compliance demand wherever it flies

Most recent

FAAAD 2021-24-17effective Jan 18, 2022ProhibitionNamed as replacement part
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This AD was prompted by reduced life limits being established for certain part-numbered tail rotor (TR) blades. This AD requires determining the total hours time-in-service (TIS) of certain part- numbered TR blades, establishing a life limit for certain part-numbered TR blades, removing from service any TR blade that has reached or exceeded its life limit, creating a component history card, re- identifying certain part-numbered TR blades, and removing any TR blade from service before reaching its retirement life. This AD also prohibits installing certain TR blades on certain model helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
FAAAD 2021-16-10effective Oct 13, 2021ProhibitionNamed as replacement part
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters. This AD was prompted by a report that geometrical non-conformities were found in the root section of the tail rotor blade (TRB). This AD requires a one-time inspection (dimensional check) of the TRB for conformity and, depending on the findings, replacement of certain affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits rework, repair, or modification of affected parts in the affected area of the TRB assembly root. The FAA is issuing this AD to address the unsafe condition on these products.

Directives citing this part number in the FAA / EASA regulatory corpus we have processed — not a complete historical AD list. An AD is a compliance requirement that drives scheduled work (inspections, replacements, modifications) on the fleets that carry the part; a directive naming this PN as the replacement part is install demand, not an action against it — and none of this is a prediction that the part will fail.
