Airworthiness Directive 2018-03-01
one-timeAirworthiness Directives; Agusta S.p.A. Helicopters
What this AD requires
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. This AD requires inspecting the main rotor blade (MRB) tip cap for disbonding. This AD is prompted by a report of the in-flight loss of an MRB tip cap. The actions of this AD are intended to prevent an unsafe condition on these helicopters.
Which aircraft AD 2018-03-01 applies to
Applies only to helicopters with an MRB P/N 3G6210A00131 with S/N 3615, 3634, 3667, or 3729 installed.
Whether AD 2018-03-01 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
