Airworthiness Directive · Amendment 39-13713 · BAE Systems (Operations) Limited Model BAe 146 Series Airplanes and Model Avro 146-RJ Series Airplanes
BAE Systems (Operations) Limited Model BAe 146 Series Airplanes and Model Avro 146-RJ Series Airplanes
All Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes, that requires 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.
To prevent possible failure of the fuel quantity indication (FQI) system, which could cause the flightcrew to act on misleading information and possibly lead to in-flight fuel exhaustion, accomplish the following:
(a) Within 2 months after the effective date of this AD, perform a detailed inspection of the wiring of the FQI system for chafing, and do any applicable corrective actions prior to further flight, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin 28-030, dated February 21, 2003.
Note 1: For the purposes of this AD, a detailed inspection is defined as: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.”
(b) Although BAE Systems (Operations) Limited Inspection Service Bulletin 28-030, dated February 21, 2003, describes procedures for reporting inspection findings to the manufacturer, this AD does not require that action.
(c) In accordance with 14 CFR 39.19, the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, is authorized to approve alternative methods of compliance for this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
