Airworthiness Directive · Amendment 39-18115 · Main rotor system
Agusta S.p.A. Helicopters
This AD applies to the following helicopters, certificated in any category:
(1) Agusta S.p.A. (Agusta) Model A109S and AW109SP helicopters, with a main rotor lag damper assembly (lag damper), part number (P/N) 109-0112-39-103 or 109-0112-39-105, installed on rod end assembly, P/N M004-01H007-041 with a serial number (S/N) 1 through 202; or rod end assembly, P/N M004-01H007-045 with a S/N 1RW through 202RW or 4964 through 5011.
(2) Agusta Model A119 and AW119 MKII helicopters, with a lag damper, P/N 109-0112-05-105 or 109-0112-05-107, installed on rod end assembly, P/N 109-0112-11-101 with a S/N 1 through 78; or rod end assembly, P/N 109-0112-11-105 with a S/N 1RW through 78RW; or rod end assembly, P/N M004-01H007-045 with a S/N 1RW through 202RW or 4964 through 5011.
We are superseding Airworthiness Directive (AD) 2014-04-14 for Agusta S.p.A. (Agusta) Model A109S, AW109SP, A119, and AW119 MKII helicopters. AD 2014-04-14 required removing certain rod end assemblies from service because of reports of fractures. This new AD retains the requirements of AD 2014-04-14 but expands the scope of applicable rod end assemblies. This AD was prompted by reports of additional fractured rod end assemblies. We are issuing this AD to prevent failure of a rod end assembly, which could result in damage to the main rotor assembly and loss of control of the helicopter.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
(1) Within 25 hours time-in-service or the next time maintenance of the helicopter involves removing the rod end assembly, whichever occurs first, remove the rod end assembly from service.
(2) Do not install a rod end assembly, P/N M004-01H007-041 with a S/N 1 through 202; P/N M004-01H007-045 with a S/N 1RW through 202RW or 4964 through 5011; P/N 109-0112-11-101 with a S/N 1 through 78; or P/N 109-0112-11-105 with a S/N 1RW through 78RW, on any 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.
