Is AD 2014-07-52 a recurring Airworthiness Directive?

Yes — AD 2014-07-52 requires a repetitive inspection every 10 hours. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2014-07-52

Q: Which aircraft does AD 2014-07-52 apply to?

AD 2014-07-52 applies to Airbus Helicopters — models AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters

What this AD requires

We are publishing a new airworthiness directive (AD) for certain Airbus Helicopters (previously Eurocopter France) Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires repetitively inspecting certain reinforcement angles of the rear structure to tailboom junction frame (reinforcement angles) for a crack, and repairing any cracked reinforcement angle. This AD is prompted by a report that cracks were found in the reinforcement angles on several AS355 helicopters. These actions are intended to detect a crack in the reinforcement angle, which if not corrected, could result in loss of the tailboom and subsequent loss of control of the helicopter.

Repetitive inspection. Re-inspect every 10 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — 350A08.2493.21, 350A08.2493.23.

Applies only to helicopters with Modification (MOD) 07 3215 installed, or with a reinforcement angle P/N 350A08.2493.21 or 350A08.2493.23 installed.

Whether AD 2014-07-52 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 2014-07-52 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.
