EASA 2023-0028

Supersedes but retains the requirements of EASA AD 2021-0283R1, which mandates repetitive visual inspections of the rivets on the rear transmission shaft bearing support and of the local structure for presence of cracks, visual inspections of the rivet heads on the outside face of the tail boom corner support, and any necessary corrective actions. Updated AD also requires a one-time inspection for the presence of finishing paint applied on the gutter and its removal because it could prevent the detection of cracks.
