Two GE engine models added

The FAA is proposing to add General Electric Model CF34-10E5 and CF34-10E5A1 engines to the airworthiness directive. If you own or operate those engine models, they would become subject to the safety requirements in the proposed AD.

Revised proposal increases burden

The FAA states the revised proposal would impose an additional burden beyond the earlier notice, so affected owners/operators may need to make changes and could face extra work and costs. The agency is requesting comments on this supplemental NPRM before finalizing the rule.
