AD 2023-15-01 Airworthiness Directives; Pratt & Whitney Canada Corp. Engines
Models named: PW307D. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Pratt & Whitney Canada Corp. (P&WC) Model PW307D engines.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For engines with an HPT 2nd-stage disk, part number (P/N) 30P3182-01, with serial number (S/N) A004D8X1 or A004E9K3 installed, within 100 engine cycles after the effective date of this AD, remove the HPT 2nd-stage disk from service.
Unsafe condition
This AD was prompted by a root cause analysis of an event involving an International Aero Engines AG Model V2533-A5 engine, which experienced an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. The FAA is issuing this AD to prevent failure of the HPT 2nd-stage disk. The unsafe condition, if not addressed, could result in uncontained HPT disk failure, damage to the engine, damage to the airplane, and loss of the airplane.
Affected ADs
None.
