Airworthiness Directives; Eurocopter France Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter France Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters with certain Aerazur emergency flotation gear attachment brackets (brackets) installed. This AD requires an initial and recurring inspection of the brackets for a crack, and if there is a crack, replacing the cracked bracket with an airworthy bracket. This AD was prompted by reports of cracks on the brackets. The actions of this AD are intended to prevent failure of the emergency flotation system and loss of float stability in the event of a water landing.

Repetitive inspection. Re-inspect every 13 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — 158172, 158173, 158288, 158289.

Applies only to helicopters with an Aerazur emergency flotation gear attachment bracket bearing one of the listed part numbers installed. Condition is a crack in an attachment bracket of the emergency flotation gear.

Whether AD 2012-25-01 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:

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.

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.
