Airworthiness Directives; Learjet Inc. Model 60 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Learjet Inc. Model 60 airplanes. This proposed AD was prompted by two incidents of swapped fire extinguishing wires. This proposed AD would require inspecting the electrical leads routed to the fire extinguishing containers for proper identification and missing labels, and to ensure the electrical leads are connected to the correct squibs; and corrective actions if necessary. We are proposing this AD to prevent the extinguishing agent of the fire extinguishing container from being delivered to the wrong engine in the event of an engine fire, and a consequent uncontrolled fire.
Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Boeing Company Model 777-200, -200LR, and -300ER series airplanes. This proposed AD was prompted by a report from the manufacturer indicating that the lowered ceiling support structure of Section 41, in airplanes incorporating the overhead space utilization (OSU) option, was found to be under-strength when subjected to a 9.0 g forward load. This proposed AD would require installing new structural members in and new tie rod(s) and attach fittings on the left and right sides of the lowered ceiling support structure. We are proposing this AD to prevent the forward lowered ceiling panels and support structure from becoming dislodged during an occurrence of a 9.0 g forward load and consequent injury to personnel or interference with an emergency evacuation.
