Airworthiness Directives; Pratt & Whitney Canada Corp. Engines

Document 2026-13058 is a Final Rule published by the Department of Transportation in the Federal Register on June 29, 2026, with an effective date of July 14, 2026. The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney Canada Corp. (P&WC) Model PW210A, PW210A1, and PW210S engines. This AD was prompted by reports of circumferential cracks found at the turbine exhaust frame external surface caused by thermal stress from engine starts. This AD requires repetitive visual inspections of the turbine exhaust frame for cracks 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.
