Airworthiness Directive · Amendment 39-21178 · Rotorcraft flight controls
Airbus Helicopters
This AD applies to all Airbus Helicopters Model EC225LP helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This AD was prompted by a mechanical deformation found on the protective cover of the "SHEAR" control pushbutton installed on a copilot collective stick. This AD requires modification of the helicopter by replacing the protective cover and re-identifying the part number of the pilot and copilot collective sticks. The FAA is issuing this AD to address the unsafe condition on these products.
For the purposes of this AD, the definitions specified in paragraphs (g)(1) through (3) of this AD apply.
(1) Affected part: A pilot or copilot collective stick having part number (P/N) 704A41110139, equipment manufacturer NSE P/N N2000355.
(2) Group 1 helicopters: Helicopters that have an affected part installed.
(3) Group 2 helicopters: Helicopters that do not have an affected part installed. A helicopter that has embodied Airbus Helicopters Modification 332P084165 in production is a Group 2 helicopter, provided that helicopter remains in that configuration.
For Group 1 helicopters: At the applicable compliance time specified in Table 1 to paragraph (h) of this AD, modify the helicopter by replacing the protective cover of the “SHEAR” control pushbutton and re-identifying the part number of the pilot and copilot collective sticks, in accordance with the Accomplishment Instructions of Airbus Helicopters Alert Service Bulletin EC225-67A017, Revision 0, dated March 26, 2018.
