What to do
Affected operators must remove and replace the specified HPT stator cases by the effective date of February 25, 2019, or within the reduced compliance times outlined in the referenced Engine Alliance service bulletins. Maintenance teams should consult Engine Alliance Alert Service Bulletin EAGP7-A72-401 Revision 1 and Service Bulletin EAGP7-72-399 for detailed procedures. Comments on the directive must be submitted by March 25, 2019, although immediate compliance is required.
Summary
FAA Airworthiness Directive 2019-02-04 is a final rule addressing Engine Alliance GP7270, GP7272, and GP7277 turbofan engines equipped with certain high-pressure turbine (HPT) stator cases. This directive mandates the removal and replacement of affected HPT stator cases due to unapproved welds discovered during manufacturing, which pose a risk of engine failure and potential fire. The directive applies specifically to HPT cases with part numbers 2060M40G02 or 2137M29G01 and certain serial numbers listed in Engine Alliance service bulletins.
What changed
This AD supersedes AD 2018-22-05 by reducing the compliance times for removal and replacement of affected HPT cases and identifying additional parts that must be removed. It updates the risk analysis based on new findings of undocumented welds, increasing the urgency for compliance. The directive retains the original removal and replacement requirements but enforces stricter timelines and expands the scope of affected parts.
Why it matters
This directive is critical for aviation professionals because failure to comply could result in engine fire and damage to the aircraft, posing a serious safety risk. Operators and maintenance organizations must prioritize inspection and replacement of the affected HPT cases to maintain airworthiness and regulatory compliance. The reduced compliance times require prompt action to mitigate the unsafe condition and avoid operational disruptions.
