SUPPLEMENTARY INFORMATION:
Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
No. 20200199, dated September 21, 2020, and corrected September 24, 2020

EASA AD 20200199, to correct an unsafe condition for Helicopteres Guimbal HG Model Cabri G2
helicopters. EASA advises of a report of a crack in a rotating scissor fitting discovered during maintenance.
According to EASA, the suspected root cause of the crack was corrosion under residual stress. This condition, if not addressed, could result in failure of the rotating or non-rotating scissor fitting on either the MRH or the swashplate guide, and subsequent loss of control of the helicopter.
Accordingly, EASA AD 20200199
requires an initial and repetitive inspections of the rotating and nonrotating scissor fittings part number P/
N G1200200 installed on the MRH or swashplate guide, respectively. If a crack is detected, the EASA AD requires replacing the affected MRH or swashplate guide with a serviceable part. The EASA AD prohibits installing certain MRHs and swashplate guides unless the initial inspection has been accomplished. The EASA AD also requires reporting certain information to HG.
FAAs Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design.

CFR Part 51
