Supersedure: None



### ATA 27 Flight Control

– Collective and Cyclic Control System

– Inspection / Restoration

Manufacturer(s): AgustaWestland Philadelphia Corporation (formerly Agusta Aerospace Corporation).

Applicability: AW139 helicopters manufacturer serial number (S/N) from S/N 41201 to S/N 41310 (except S/N 41290, S/N 41291, S/N 41292, S/N 41302, 41304, 41305, 41306 and 41309 ) not having yet performed the first scheduled 1 200 Flight Hours ( FH ) / 2 years checks (or the first 1 year checks for saline and/or high humidity environment operation conditions).

Reason: An occurrence of incorrect installation of pilot collective stick, pilot cyclic stick and co

- pilot cyclic stick was reported. This discrepancy was identified in service, during a defect rectification carried out following a service difficulty. The results of the subsequent technical investigation, carried out by AgustaWestland, concluded that this discrepancy could potentially affect a number of other helicopters.
This condition, if not detected and corrected, could lead to in

- flight detachment of the cyclic and collective sticks, resulting in loss of control of the helicopter. To address this unsafe condition, AgustaWestland have developed Bollettino Tecnico (BT) 139

- 308, which gives instructions to inspect the proper installation of the affect ed cyclic and collective sticks. For the reasons described above, this AD requires accomplishment of a one

time inspection of the collective and cyclic sticks of the helicopter and, depending on findings, the accomplishment of applicable corrective actions.EASA AD No.: 2012
