Airworthiness Directive · Amendment 39-15600 · Agusta S.p.A. Model A109E and A119 Helicopters
Agusta S.p.A. Model A109E and A119 Helicopters
This AD applies to Agusta S.p.A. Model A109E and A119 helicopters, with hydraulic lines, part number (P/N) 109-0761-64-103 or P/N 109-0761-65-103, installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E and A119 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the Technical Agent for Italy, with which we have a bilateral agreement, states in the MCAI: "Some cases of interference between the hydraulic pipe, P/N 109-0761-65-103, and the tail rotor control rod assembly have been detected on Model A109E helicopters * * * The interference, if not corrected, could damage the hydraulic pipes and lead to the loss of the hydraulic system No. 1 in flight. This AD * * * is issued to extend the same mandatory corrective actions to A119 model due to its design similarity with A109E." This AD requires actions that are intended to address this unsafe condition.
Within the next 50 hours time-in-service (TIS), unless accomplished previously, and thereafter at intervals not to exceed 100 hours TIS:
(1) Inspect for interference between the hydraulic lines, P/N 109-0761-64-103 and P/N 109-0761-65-103, and the tail rotor control rod assembly, P/N 109-0032-01-41, in accordance with the Compliance Instructions, Part I, paragraph 3, of Agusta Bollettino Tecnico (BT) No. 109EP-73, dated December 4, 2006 (BT A109E), which is applicable to Model A109E helicopters, or BT 119-22, dated July 11, 2007 (BT 119-22), which is applicable to Model A119 helicopters.
(2) If you find interference between the hydraulic lines and the tail rotor control rod assembly, replace the hydraulic lines, P/N 109-0761-64-103 and P/N 109-0761-65-103, with hydraulic lines, P/N 109-0763-96-101 and P/N 109-0763-97-101, respectively, in accordance with the Compliance Instructions, Part II of BT A109E or BT 119-22, whichever is applicable to your model helicopter.
(f) Within 180 days, replace hydraulic lines, P/N 109-0761-64-103 and P/N 109-0761-65-103, with hydraulic lines, P/N 109-0763-96-101 and P/N 109-0763-97-101, respectively, in accordance with the Compliance Instructions, Part II, of BT A109E or BT 119-22, whichever is applicable to your model helicopter.
This AD requires replacement of hydraulic lines, P/N 109-0761-64-103 and P/N 109-0761-65-103, within 180 days, unless previously accomplished, instead of replacing the hydraulic lines on the dates specified in the MCAI.
Alternative Methods of Compliance (AMOCs): The Manager, Safety Management Group, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
