Airworthiness Directive 2003-22-11
one-timeAirworthiness Directives; Eurocopter France Model AS350B, B1, B2, B3, BA, C, D, D1, and AS355E, F, F1, F2, and N Helicopters
What this AD requires
This amendment supersedes an existing airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) Model AS350B, B1, B2, B3, BA, D, and AS355E helicopters, that currently requires removing certain serial-numbered main servocontrols before further flight. This amendment contains the same requirements but also requires removing certain other main and tail servocontrols on or before 550 hours time- in-service (TIS) or 24 months, whichever occurs first. Also, this amendment adds the Eurocopter Model AS350C, D1, and AS355F, F1, F2, and N helicopters to the applicability. This amendment is prompted by the discovery of a manufacturing defect in another set of servocontrols. The actions specified by this AD are intended to prevent failure of a main or tail servocontrol in the flight control system and subsequent loss of control of the helicopter.
Which aircraft AD 2003-22-11 applies to
Applies to all listed models except helicopters with TRW-SAMM main and tail servocontrols that have been reconditioned and identified by the letter 'V' engraved on the identification plate on the right-hand side of the part number.
Whether AD 2003-22-11 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:
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.
