EASA Regulations for Pratt & Whitney JT8D Series 200

Engine - Stage 3/4 Low Pressure Turbine Blades and LPT-to-Exhaust Case Bolts - Inspection / Replacement

Airworthiness Directive 2021-22-19 is a final rule issued by the FAA addressing Pratt & Whitney JT8D-209, JT8D-217, JT8D-217A, JT8D-217C, and JT8D-219 turbofan engines. It mandates revised inspection and replacement requirements for the 3rd-stage and 4th-stage low-pressure turbine (LPT) blades and LPT-to-exhaust case bolts to prevent unsafe conditions. This directive applies to engines installed on aircraft such as the MD-82 and aims to enhance engine safety by preventing LPT blade fracture and uncontained blade release.
