FAA Tells Jet Engine Owners: Check Those Turbines Again
Published Date: 1/23/2025
Proposed Rule
Summary
The FAA is updating rules for certain General Electric jet engines to keep them safe, now including more engine models than before. If you own or operate these engines, you might need to make some fixes to avoid problems. The FAA wants your feedback before finalizing these changes, which could mean some extra work and costs soon.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
More GE Engine Models Covered
If you own or operate General Electric CF34-10E5 or CF34-10E5A1 engines, the FAA is adding those models to a proposed airworthiness directive that already covered CF34-10E2A1, CF34-10E6, CF34-10E6A1, CF34-10E7, and CF34-10E7-B engines with certain part-numbered high-pressure turbine (HPT) shroud/low pressure turbine (LPT) nozzle assemblies installed. That means the proposed safety rule now explicitly applies to those additional engine models.
Proposed AD Adds Compliance Burden
The FAA says the proposed airworthiness directive would require actions to address an unsafe condition and would impose an additional burden compared with the earlier proposal. If your aircraft has the affected engines with the specified HPT shroud/LPT nozzle assemblies, you may need to perform inspections or fixes, which could mean extra work and costs.
