Model AS350B, B1, B2, B3, BA, D, and AS355E helicopters, with TRW-SAMM main servocontrols, part number (P/N) SC 5083, serial number (S/N) from 1500 to 1515, inclusive, or P/N SC 5084, S/N from 722 to 726, inclusive, installed, except those reconditioned and identified by the letter "V" engraved on the identification plate on the right-hand side of the P/N, certificated in any category.
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2001-26-53, which was sent previously to all known U.S. owners and operators of Eurocopter France (ECF) Model AS350B, B1, B2, B3, BA, D, and AS355E helicopters by individual letters. This AD requires, before further flight, removing certain serial-numbered servocontrols. This AD is prompted by a report of manufacturing defects in a batch of main servocontrol rods. The actions specified by this AD are intended to prevent failure of a main servocontrol in the flight control system and subsequent loss of control of the helicopter.
