Airworthiness Directives: General Electric Company Engines

Hop-A-Jet Worldwide Jet Charter, Inc. supports the FAA's decision to deviate from GE's service bulletins by requiring visual borescope inspections for corrosion in the VGV bores. The company argues that GE's position minimizes safety risks and recommends further requirements, such as reduced functional check intervals when active corrosion is detected and a requirement for certified trained technicians to perform the inspections.

The Air Line Pilots Association (ALPA), a union representing over 80,000 professional airline pilots, supports the proposed Airworthiness Directive for certain General Electric Company engines. They agree with the requirements for restart tests, borescope inspections, and potential maintenance actions to address corrosion in the high-pressure compressor case.

StandardAero, an authorized GE CF34-3 MRO, supports the proposed Airworthiness Directive but requests specific technical amendments to clarify engine applicability and inspection procedures. They advocate for more precise definitions of "Group 3 engines" and the inclusion of alternative inspection options to simplify maintenance workflows.

GE Aerospace is submitting technical comments regarding a proposed Airworthiness Directive for General Electric Company engines. The company proposes specific revisions to the NPRM to clarify inspection methods, compliance categories, and technical descriptions to ensure they align with practical operator needs and existing Service Bulletins.

Aero Services Unlimited, representing a maintenance service provider, supports the FAA's issuance of an Airworthiness Directive to address corrosion and wear in GE engines. They argue that the current inspection processes are inadequate and recommend specific borescope inspection intervals and functional checks to ensure public safety.
