AD 2021-10-25 Requires Cleaning Affected Parts, Visual And Dye Penetrant Inspections For Cracks Of Affected Parts
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC130B4 and EC130T2 helicopters.
This AD was prompted by a report of cracks and geometrical non-conformities of the tail rotor blades (TRBs); all cracks initiated in the drain hole area at the blade root section. This AD requires cleaning affected parts, visual and dye penetrant inspections for cracks of affected parts, a dimensional inspection to verify conformity of affected parts, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective July 6, 2021.
Supplementary Information: The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0187, dated August 21, 2020 (EASA AD 2020-0187) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Model EC130B4 and EC130T2 helicopters.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Helicopters Model EC130B4 and EC130T2 helicopters. The NPRM published in the Federal Register on March 15, 2021 (86 [[Page 29177]] FR 14290). The NPRM was prompted by a report of cracks and geometrical non-conformities of the TRBs; all cracks initiated in the drain hole area at the blade root section. The NPRM proposed to require cleaning affected parts, visual and dye penetrant inspections for cracks of affected parts, a dimensional inspection to verify conformity of affected parts, and corrective actions if necessary, as specified in an EASA AD.
The FAA is issuing this AD to address geometrical non-conformities of the TRBs, which could lead to crack initiation and consequent blade failure, and possible loss of control of the helicopter. See the MCAI for additional background information
