EASA 2023-0001

Supercedes but retains the requirements of EASA AD 2022-0038, which requires repetitive inspections of the TGB magnetic plug at reduced intervals, the use of new criteria for particle assessment and, depending on findings, replacement of the tail rotor gearbox (TGB) or the dual bearing, as applicable, for Group 1 helicopters. Since that AD was issued, further investigation determined the need for an additional one-time inspection of the TGB control rod dual bearing for Group 2 helicopters.
