Airworthiness Directive · Amendment 39-17330 · Ice and rain protection
BAE SYSTEMS (OPERATIONS) LIMITED Airplanes
This AD applies to all BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146-100A, -200A, and -300A airplanes; and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any category; all serial numbers.
We are adopting a new airworthiness directive (AD) for all BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146, and Avro 146-RJ series airplanes. This AD was prompted by a report of loss of the end caps on the anti-icing piccolo tube of the wing leading edge. This AD requires a detailed inspection of the end caps on the anti-icing piccolo tube for lost or loose end caps, and replacing or repairing the end caps if necessary. We are issuing this AD to detect and correct lost and loose end caps on the anti-icing piccolo tube, and ice accretion on the wing leading edge or run-back ice, which could lead to a reduction in the stall margin on approach and loss of controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 12 months after the effective date of this AD: Do a detailed inspection of the end caps on the anti-icing piccolo tube for lost and loose end caps, in accordance the Accomplishment Instructions of BAE SYSTEMS (OPERATIONS) LIMITED Inspection Service Bulletin ISB.30-025, dated April 19, 2011.
If, during the detailed inspection required by paragraph (g) of this AD, a lost or loose end cap of the anti-icing piccolo tube is found: Before next flight, replace the end cap, in accordance the Accomplishment Instructions of BAE SYSTEMS (OPERATIONS) LIMITED Inspection Service Bulletin ISB.30-025, dated April 19, 2011, or repair in accordance with a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA) (or its delegated agent).
BAE SYSTEMS (OPERATIONS) LIMITED Inspection Service Bulletin ISB.30-025, dated April 19, 2011, specifies a reporting requirement; this AD does not require reporting.
