### ATA 56 Windows – Pilot and Co-pilot Door Windows Bo nding – Inspection

Manufacturer(s): AgustaWestland S.p.A (formerly Agusta S.p.A.), Agus taWestland Philadelphia Corporation (formerly Agusta Aerospace Corporation)

.
Applicability: A119 and AW119MkII helicopters, all serial numbers (S/N) up to S/N 14781 included.
Reason: On an AW119MKII helicopter, the pilot door window detached during a test flight. No injuries to the occupant or damage to th e helicopter occurred. The results of the investigation revealed that the event was caused by the lack of the bonding of the seal both to the window and to the door structure. This condition, if not detected and corrected, coul d lead to in-flight separation of the pilot and/or co-pilot door windows, possibly resulting in damage to the helicopter or injuries to persons on the ground. To address this condition, AgustaWestland issued Bo llettino Tecnico (BT) 119-47 to provide the necessary instructions to ass ure the correct bonding of the windows and the relevant seal to the window fra me of the pilot and copilot doors. For the reasons described above, this AD requires t o inspect the pilot and copilot door windows to verify the bonding between se al and window, and the accomplishment of the applicable corrective actions
