Airworthiness Directives; Eurocopter Model AS350B, B1, B2, B3, BA, D, and AS355E Helicopters

What this AD requires

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter helicopters. This action requires, within 10 hours time-in-service (TIS), inspecting the tapered housing of each main servo-control (MSC) for a crack. If no crack is found, this AD requires, before further flight, retorquing the upper ball-end attachment nut of the MSC. If a crack is found, this AD requires, before further flight, replacing the MSC with an airworthy MSC. This amendment is prompted by the discovery of cracks in the tapered housings of MSCs. The actions specified in this AD are intended to detect a crack in the MSC tapered housing and to prevent loss of the attachment of the MSC to the upper attachment yoke, loss of the main rotor control, and subsequent loss of control of the helicopter.

ModelsAS350, AS355

Applies to main rotor servo-controls (MSCs) not modified per MOD 073343 and on which the tightening torque of the attachment nut securing the upper ball end has been increased by following MOD 073191 or complying with MET Work Card 67.30.00.402 since MET Revision 04-06 (Model AS350 helicopters) or Revision 04.08 (Model AS355 helicopters).

Whether AD 2006-19-01 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 2006-19-01 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.
