Airworthiness Directive · Amendment 39-14594 · Bombardier Model BD-100-1A10 Airplanes
Bombardier Model BD-100-1A10 Airplanes
This AD applies to Bombardier Model BD-100-1A10 airplanes, serial numbers 20006 through 20046 inclusive, 20048, 20051, and 20052; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model BD-100-1A10 airplanes. This AD requires an inspection for signs of arcing or heat damage of the electrical connections of the terminal blocks, ground studs, and the end of the wires and surrounding insulation for the windshield and side window anti-ice systems; and repairing any arced or damaged electrical connection. This AD also requires re-torquing electrical connections of the terminal blocks and ground studs for the windshield and side window anti-ice systems. This AD results from an in-service incident involving smoke and odor in the cockpit. We are issuing this AD to prevent loose electrical connections that could arc and overheat, and cause wiring damage of the windshield and side window anti-ice systems. Such wiring damage could result in smoke and/or fire in the flight compartment.
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 90 days after the effective date of this AD, do the actions specified in paragraphs (f)(1) and (f)(2) of this AD in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin A100-30-03, Revision 01, dated December 21, 2005.
(1) Do a detailed inspection for signs of arcing or heat damage of the electrical connections of the terminal blocks, ground studs, and the end of the wires and surrounding insulation for the windshield and side window anti-ice systems. If any sign of arcing or heat damage is detected, before further flight, repair the arced or damaged electrical connection.
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.”
(2) Re-torque the electrical connections of the terminal blocks and ground studs for the windshield and side window anti-ice systems.
