EASA PAD 26-113
Sep 23, 2026Engine – High Pressure Turbine Front Seal – Inspection
EASA Airworthiness Directive Proposal 26-113 is a regulatory document addressing the inspection of the High Pressure Turbine (HPT) front seal on CFM INTERNATIONAL S.A. CFM56-5B and CFM56-7B engine models. These engines are commonly installed on Airbus A318, A319, A320, and A321 series aircraft, as well as Boeing 737-600, 737-700, 737-800, 737-900, and 737-900ER series aircraft. The directive proposes a one-time on-wing borescope inspection to detect potential misalignment and cracks in the HPT front seal to prevent uncontained part release and possible engine or aircraft damage.
