The FAA's summary their words, unchanged

The FAA is superseding Airworthiness Directive (AD) 2021-11-17 and AD 2021-11-22, which applied to all Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3 and EC635T2 helicopters. AD 2021-11-17 required a one-time visual inspection of certain part-numbered main rotor actuators (MRAs). AD 2021-11-22 required revising the life limits of certain parts and removing each part that had reached its life limit. Since the FAA issued those ADs, it was determined that repetitive inspections of the MRAs are necessary, new and more restrictive tasks and limitations have been issued, and that it is necessary to expand the applicability. This AD continues to require the actions required by AD 2021-11-17 and AD 2021-11-22, except this AD requires changing the one-time MRA inspection to a repetitive inspection and incorporating other new and more restrictive tasks and limitations by revising the airworthiness limitations section (ALS) of the existing helicopter maintenance manual or instructions for continued airworthiness and the existing approved maintenance or inspection program, as applicable. This AD also expands the applicability by adding Model EC635T2+ helicopters. These actions are 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.
