Airworthiness Directives; Eurocopter France Model AS 332L2 Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model AS 332L2 helicopters. This action requires modifying the main rotor blade vibration absorber (vibration absorber) by replacing the weight support assemblies with reinforced weight support assemblies. This amendment is prompted by a report of the failure of a weight support assembly in-flight. The actions specified in this AD are intended to prevent failure of a vibration absorber weight support assembly, which could lead to adverse vibrations, contact between the fuselage and a main rotor blade or loss of a main rotor blade; and subsequent loss of control of the helicopter.

Which aircraft AD 98-04-48 applies to

Part-conditional332A11-0460-01, 332A11-0460-02, 332A11-0470-00, 332A11-0474-00.

Specific model not stated in the provided applicability excerpt (part number prefix 332A11 is consistent with the AS332 series but not explicitly named in this text). Requires converting vibration absorber P/N 332A11-0460-01 to P/N 332A11-0460-02 by replacing weight support assembly P/N 332A11-0470-00 with P/N 332A11-0474-00, per Eurocopter France SB 62.00.43 dated Feb 13, 1997, within 25 hours TIS. Special flight permits will not be issued.

Whether AD 98-04-48 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:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 98-04-48 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
