Airworthiness Directives; Eurocopter France Model EC 120 Helicopters

What this AD requires

This amendment supersedes an existing airworthiness directive (AD) that applies to Eurocopter France (ECF) Model EC120B helicopters and currently requires adjusting the clearance of the cabin sliding door if necessary. This amendment requires adding an end stop to the front rail and modifying the rear stop of the middle rail to increase its adjustment range for certain cabin sliding doors. This amendment is prompted by an in-flight loss of a cabin sliding door, which had been locked in the open position. The actions specified by this AD are intended to prevent in-flight loss of a cabin sliding door, impact with the horizontal stabilizer or fenestron tail rotor, and subsequent loss of control of the helicopter.

Which aircraft AD 2001-24-08 applies to

MakesEurocopter
ModelsEC120B, EC120
Serial-conditional — narrows to serials ?–1169.
Part-conditional — C533C8102201, C533C8102202, C533C8103201, C533C8103202.

Applies only to helicopters with serial number 1169 and below, with one of the listed cabin sliding door rail part numbers installed.

Whether AD 2001-24-08 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 2001-24-08 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.
