Airworthiness Directives; Costruzioni Aeronautiche Giovanni Agusta S.p.A. Model A109A, A109AII, and A109C Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain Costruzioni Aeronautiche Giovanni Agusta S.p.A. (Agusta) Model A109A, A109AII, and A109C helicopters, that requires a modification of the tail boom vertical fin to create inspection openings that permit initial and repetitive visual inspections for cracks in the vertical fin rear spar attachment area. This amendment is prompted by four reports of cracks in the tail boom vertical fin rear spar attachment area. The actions specified by this AD are intended to prevent failure of the vertical fin attachment caused by cracks in the tail boom vertical fin rear spar attachment area, and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 300 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Which aircraft AD 95-13-10 applies to

MakesAgusta
Part-conditional — 109-0370-01, 109-0370-17, 109-0822-38-101, 109-0822-38-103.

Specific helicopter models are named in a preceding applicability provision not captured in the extracted text. AD requires modification/inspection of the tail boom vertical fin per Agusta Bollettino Tecnico No. 109-96, dated March 30, 1994; modification kit used depends on installed tail boom part number (109-0370-01 uses kit 109-0822-38-101; 109-0370-17 uses kit 109-0822-38-103).

Whether AD 95-13-10 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 95-13-10 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.
