Airworthiness Directives; Pratt & Whitney Canada Corp. Engines

FAA / Federal Register · 2026-16655

The FAA is superseding Airworthiness Directive (AD) 2026-13- 09, which applied to all Pratt & Whitney Canada Corp. (P&WC) Model PW210A, PW210A1, and PW210S engines. AD 2026-13-09 required repetitive visual inspections of the turbine exhaust frame for cracks and, depending on the results of the inspections, replacement of the turbine exhaust frame. Since the FAA issued AD 2026-13-09, a manufacturer's analysis revealed that turbine exhaust frames manufactured from a certain material were less durable and more susceptible to developing cracks under thermal stress. This AD requires repetitive visual inspections of the turbine exhaust frame for cracks at different initial inspection thresholds than required by AD 2026-13-09 based on the material used during manufacture and, depending on the results of the inspections, replacement of the turbine exhaust frame. The FAA is issuing this AD to address the unsafe condition on these products.
