Airworthiness Directives; Eurocopter France Model AS 365 N3 and EC 155B Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France (Eurocopter) Model AS 365 N3 and EC 155B helicopters, that requires replacing each Fenestron pitch change control rod (control rod) with an improved reinforced steel airworthy control rod. This amendment is prompted by a failure of a control rod on a prototype helicopter and by the manufacturer making available a newly-designed reinforced steel control rod. The actions specified by this AD are intended to prevent failure of the control rod, loss of control of the tail rotor, and subsequent loss of control of the helicopter.

Part-conditional — 365A33-6161-21, 365A33-6214-20.

Applies to tail rotor control rod P/N 365A33-6161-21 on EC155B and AS365N3 helicopters (per referenced Eurocopter Alert Telex No. 04A005 for EC155B and No. 01.00.55 for AS365N3, both dated July 4, 2002). Must be removed and replaced with reinforced steel control rod P/N 365A33-6214-20; compliance time is before further flight if the rod has >=700 hrs TIS, within 20 hrs TIS if 500-699 hrs, or within 30 hrs TIS if 271-499 hrs.

Whether AD 2003-19-01 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.

Is AD 2003-19-01 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.
