Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all British Aerospace Jetstream Model 3201 airplanes. The proposed AD would require inspecting the fuel quantity indication system for damage to the insulation of the wiring within the fuel tanks. Damage is defined as corrosion (indicated by a dark stain), cuts, or nicks. The proposed AD would also require replacing or repairing any damaged wiring. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by the proposed AD are intended to detect damage to the insulation of the wiring within the fuel tanks of the fuel quantity indication system, which could result in a malfunction in the cockpit indicators and/or electrical sparking inside the fuel tank with consequent fire or explosion.
