BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ Airplanes
This AD applies to BAE Systems (Operations) Limited Model BAe 146-100A, -200A, and -300A series airplanes, and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any category; as identified in BAE Systems (Operations) Limited Inspection Service Bulletin ISB.52-113, Revision 1, dated February 11, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. This AD requires a one-time detailed inspection for corrosion of the hinge bracket assembly of the left and right main landing gear (MLG) doors, and corrective action if necessary. This AD results from in-service reports of hinge bracket failures on the MLG doors. We are issuing this AD to prevent failure of the hinge bracket on the MLG door, which could result in separation of the door, consequent structural damage to the airplane, and possible injury to people on the ground.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable time specified in paragraph (f)(1) or (f)(2) of this AD: Perform a one-time detailed inspection for corrosion of the hinge bracket assembly of the left and right MLG doors by doing all the applicable actions in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.52-113, Revision 1, dated February 11, 2005. Perform any applicable corrective action before further flight in accordance with the service bulletin. If no corrosion is found, before further flight, apply protective treatment in accordance with the service bulletin.
(1) For airplanes on which the date of issuance of the original standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness is on or before February 28, 1991: Within 192 months since the date of issuance of the original standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness, or within 12 months after the effective date of this AD, whichever is later.
(2) For airplanes on which the date of issuance of the original standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness is after February 28, 1991: Within 24 months after the effective date of this AD.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
Inspections accomplished before the effective date of this AD in accordance with BAE Systems (Operations) Limited Inspection Service Bulletin ISB.52-113, dated February 2, 2001, are considered acceptable for compliance with the corresponding action specified in this AD.
As of the effective date of this AD, no person may install, on any airplane, a hinge bracket assembly of the left and right MLG doors, unless it has been inspected (and any corrective actions done) according to BAE Systems (Operations) Limited Inspection Service Bulletin ISB.52-113, Revision 1, dated February 11, 2005.
(i) Although BAE Systems (Operations) Limited Inspection Service Bulletin ISB.52-113, Revision 1, dated February 11, 2005, referenced in this AD, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
