Abstract
The FAA is superseding airworthiness directive (AD) 2021-24- 06, which applied to certain Airbus Helicopters Model EC130T2 helicopters. AD 2021-24-06 required repetitive visual inspections of the rivets on the rear transmission shaft bearing support and of the local structure for cracking and missing, loose, or sheared rivets and accomplishment of applicable corrective actions. This AD retains those requirements and adds repetitive visual inspections of the rivet heads on the left-hand and right-hand sides of the rear transmission shaft bearing support, revises a corrective action, and adds a reporting requirement, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also revises the special flight permit limitation from AD 2021-24-06. This AD was prompted by an additional report of loose rivet heads on the outside face of the tail boom corner support. The FAA is issuing this AD to address the unsafe condition on these products.
