Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Learjet Inc. Model 45 airplanes. This proposed AD was prompted by a report that the fire barrier seal on the external baggage door does not seal the surrounding door structure due to incorrect positioning of the barrier. This proposed AD would require modifying the fire seal on the baggage door, including doing inspections of the fire seal for correct contact and corrective action if necessary. We are proposing this AD to prevent improper sealing of the baggage door, which could increase the risk of an uncontained fire in the baggage compartment.
