Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Model 400A series airplanes. This proposed AD would require inspecting the galley cabinets to determine if a certain part number is installed or if a certain size of wire already exists, and doing related investigative/corrective actions if necessary. This proposed AD results from reports of undersized, and consequently unprotected, wire in the galley cabinets. We are proposing this AD to prevent overheating of wire insulation and consequent fire or smoke in the airplane cabin.
