Airworthiness Directive · Amendment 39-17583 · Flight compartment windows
AgustaWestland S.p.A. Helicopters
This AD applies to AgustaWestland S.p.A. (AgustaWestland) Model A119 and AW119 MKII helicopters, serial numbers up to and including 14781, certificated in any category.
We are adopting a new airworthiness directive (AD) for AgustaWestland S.p.A. (AgustaWestland) Model A119 and AW119 MKII helicopters to require inspecting the pilot and co-pilot doors to ensure that the windows are properly bonded within the doors. If the windows are not properly bonded, the AD requires applying bonding to the windows, the seals, and the window frames of the pilot and co-pilot doors. This AD was prompted by the loss of a pilot-door window during a test flight. The actions of this AD are intended to ensure the windows do not detach from the doors, potentially injuring persons on the ground and damaging the helicopter's tailboom and the tail rotor blades.
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.
Within the next 50 hours time-in-service (TIS) or within the next five months, whichever comes first:
(1) Visually inspect the pilot and co-pilot doors by referencing Figure 1 of AugustaWestland Bollettino Tecnico 119-47, dated March 29, 2012 (BT), to determine whether there is bonding between the seal (3) and the window (4) in the internal and external side of the seal's junction area.
(2) If there is no bonding, before further flight, apply bonding to the windows, seals, and window frames in accordance with the Compliance Instructions, paragraphs 5 through 20, of the BT.
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.
