Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This proposal would require performing a detailed inspection for chafing of the fuel quantity indication (FQI) system wiring, and any applicable corrective actions. These actions are necessary to prevent possible failure of the FQI system, which could cause the flightcrew to act on misleading information and possibly lead to in-flight fuel exhaustion. This action is intended to address the identified unsafe condition.
