Superseded. A later AD replaced this one: AD 2016-03-05. Comply with the one in force.
This AD applies to Airbus Helicopters Model MBB-BK 117 C-2 helicopters with a Goodrich hoist damper unit, part number (P/N) 44307-480, P/N 44307-480-1, or P/N 44307-480-2, installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model MBB-BK 117 C-2 helicopters with a certain Goodrich rescue hoist damper unit (damper unit) installed. This AD requires repairing or replacing the damper unit or deactivating the rescue hoist. This AD is prompted by a report of an uncommanded detachment of a damper unit from the cable. These actions are intended to prevent loss of an external load or person from the helicopter hoist and injury to persons being lifted by the hoist.
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.
Before the next hoist operation, comply with paragraph (e)(1), (e)(2), or (e)(3) of this AD:
(1) Repair and re-identify each hoist damper unit in accordance with the Accomplishment Instructions, paragraph 3.B.1, of Airbus Helicopters Emergency Alert Service Bulletin ASB No. MBB-BK117 C-2-85A-041, Revision 2, dated March 4, 2014; or
(2) Replace each hoist damper unit with a unit that has been repaired as required by paragraph (e)(1) of this AD; or
(3) Deactivate the rescue hoist system.
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.
