Airworthiness Directive · Amendment 39-21725 · Rotorcraft flight control
Hélicoptères Guimbal Helicopters
This AD applies to Hélicoptères Guimbal Model CABRI G2 helicopters, certificated in any category, with main rotor (MR) non-rotating scissor links, part number (P/N) G41-10-200 installed.
The FAA is adopting a new airworthiness directive (AD) for certain H[eacute]licopt[egrave]res Guimbal Model CABRI G2 helicopters. This AD was prompted by a report that, during scheduled maintenance on two helicopters, cracks were found on a certain main rotor (MR) non- rotating scissor link. This AD requires replacing an affected MR non- rotating scissor link with a serviceable part. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Within 50 hours time-in-service or 2 months after the effective date of this AD, whichever occurs first, modify the helicopter by replacing the MR non-rotating scissor link, P/N G41-10-200, with a serviceable scissor link assembly, P/N G41-12-100, in accordance with the Required Actions, IPC 4.1-2 (a) through (d) inclusive, of Guimbal Service Bulletin SB 15-015, Revision C, dated August 27, 2019.
(2) As of the effective date of this AD, do not install a MR non-rotating scissor link, P/N G41-10-200, on any helicopter.
