What the agency says
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters modified by Supplemental Type Certificate (STC) SR00223IB. This AD was prompted by reports of various deficiencies on the parts installed on the jettisonable window system. This AD requires removing the jettisonable window and, depending on the removal results, replacing the locking fingers; inspecting and installing any missing retaining rings; and inspecting the left-hand (LH) side and right-hand (RH) side emergency handle latch covers (covers) and, depending on the inspection results, replacing the covers or reinstalling airworthy covers. This AD also requires performing repetitive lubrication of the locking fingers installed on the windows jettisonable system and repetitive operational tests of the windows jettisonable system after each lubrication. Additionally, this AD requires modifying the helicopter by replacing each cover and prohibits the installation of certain window aesthetic covers or electrochromic windows unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
