AD 2026-16-13 Airworthiness Directives; Pratt & Whitney Canada Corp. Engines
Models named: PW210A, PW210A1, PW210S. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Pratt & Whitney Canada Corp. Model PW210A, PW210A1, and PW210S engines.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For the purpose of this AD, an “engine start” includes the start of an engine for any reason, even if it is not followed by a flight.
Unsafe condition
This AD was prompted by reports of circumferential cracks found at the turbine exhaust frame external surface caused by thermal stress from engine starts. The FAA is issuing this AD to prevent failure of the turbine exhaust frame. The unsafe condition, if not addressed, could result in turbine exhaust frame failure, which could lead to loss of axial containment, release of parts, and damage to the helicopter.
Affected ADs
This AD replaces AD 2026-13-09, Amendment 39-23391 (91 FR 38991, June 29, 2026).
