one-timeAirworthiness Directives; Agusta S.p.A. Model A109E Helicopters
What this AD requires
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2000-25-54, which was sent previously to all known U.S. owners and operators of Agusta (Agusta) S.p.A. Model A109E helicopters by individual letters. This AD requires, before each start of the engines, visually checking both sides of each tail rotor blade (blade) for a crack and, at specified intervals, inspecting each blade for a crack using a 5-power or higher magnifying glass. Dye-penetrant inspecting each blade for a crack is also required at specified time intervals. If a crack is found, replacing the blade with an airworthy blade is required before further flight. This amendment is prompted by five reports of cracked tail rotor blades. The actions specified by this AD are intended to prevent failure of a blade and subsequent loss of control of the helicopter.
Which aircraft AD 2000-25-54 applies to
Cross-reference boilerplate only; model list precedes excerpt and was not captured. Requires a pre-start visual check of each tail rotor blade for cracks, a 10-hour-TIS-interval 5-power-magnifier visual inspection, and a 25-hour-TIS-interval dye-penetrant inspection, replacing any cracked blade before further flight; per Agusta S.p.A. Alert Bollettino Tecnico No. 109EP-14, dated October 11, 2000. Special flight permits prohibited.
Whether AD 2000-25-54 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.
