Airworthiness Directive 2024-01-11
one-timeAirworthiness Directives; Various Helicopters
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all helicopters with certain Pacific Scientific Company rotary buckle assemblies (buckles) installed. This AD was prompted by a report of a manufacturing defect in the screws used inside the buckle. This AD requires inspecting the buckle screws and, depending on the results, reidentifying the buckle, replacing the screws and reidentifying the buckle, or replacing the buckle. This AD also prohibits installing certain buckles. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2024-01-11 applies to
Applies to all helicopters, certificated in any category, with a restraint system having a Pacific Scientific Company rotary buckle assembly P/N 1111475 (all dash numbers) or P/N 1111548-01 installed, manufactured between January 2012 and September 2012 inclusive, or with an unknown date of manufacture. These buckles may be installed on, but are not limited to, Airbus Helicopters model helicopters.
Whether AD 2024-01-11 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.
