Airworthiness Directive · Amendment 39-13238 · Eurocopter France Model SA-365N, N1, AS-365N2, AS 365 N3, SA-366G1, AS355F, F1, F2, N, and EC130 B4 Helicopters
Eurocopter France Model SA-365N, N1, AS-365N2, AS 365 N3, SA-366G1, AS355F, F1, F2, N, and EC130 B4 Helicopters
Model SA-365N, N1, AS-365N2, N3, SA-366 G1, AS355F, F1, F2, N and EC130 B4 helicopters, with TRW-SAMM main servocontrols, part number SC8031, SC8031A, SC8031-1, SC8031-2, SC8032-1, SC8032-2, SC8033-1, SC8033-2, SC8034-1, SC8034-2, SC8042 or SC8043, overhauled or repaired at Hawker Pacific Aerospace before March 1, 2002, installed, certificated in any category.
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters that requires removing certain main servocontrols and replacing them with servocontrols that do not fall within the "Applicability" of this AD at specified intervals. This amendment is prompted by the discovery of an incorrect tightening torque load found on servocontrols that were overhauled by Hawker Pacific Aerospace. The actions specified by this AD are intended to prevent thread failure, separation of the upper end fitting that attaches the servocontrol cylinder to the upper ball end- fitting, and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
