What to do
Affected operators must perform a visual inspection of the engine fan hub within 90 days of the AD's effective date, July 11, 2018, following the procedures in Pratt & Whitney Service Bulletin PW1000G-C-72-00-0104-00A-930A-D, Issue No. 002. If damage or defects are found outside serviceable limits, the engine fan hub must be replaced before further flight. Comments on the AD may be submitted until August 10, 2018.
Summary
Federal Register Volume 83, Number 123 (June 26, 2018) is a final rule Airworthiness Directive (AD 2018-13-03) issued by the FAA for certain International Aero Engines PW1100G-series turbofan engines, including models PW1133G-JM, PW1133GA-JM, PW1130G-JM, PW1127G-JM, PW1127GA-JM, PW1127G1-JM, PW1124G-JM, PW1124G1-JM, and PW1122G-JM. The AD mandates a one-time visual inspection of the engine fan hub for damage and requires removal of parts if defects exceed serviceable limits. This directive addresses safety concerns related to potential uncontained engine fan hub failure.
What changed
This new Airworthiness Directive introduces a mandatory one-time visual inspection of the engine fan hub on specified IAE PW1100G-series engines. It requires removal and replacement of the engine fan hub if damage or defects are found beyond allowable limits. The AD expands applicability beyond the related Pratt & Whitney service bulletin by including all serial numbers up to 770735 without exclusions.
Why it matters
This AD is critical for aviation professionals because it addresses a safety risk that could lead to uncontained engine failure, posing hazards to the aircraft and passengers. Operators and maintenance organizations must ensure compliance to prevent potential in-flight engine damage. Timely inspections and corrective actions help maintain airworthiness and avoid costly unscheduled repairs or incidents.
