Airworthiness Directive · Amendment 39-21555 · Fuel
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-1A10 airplanes, certificated in any category, serial numbers 9657 through 9844 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 airplanes. This AD was prompted by a report indicating that during installation, a fuel pipe bracket assembly on the intermediate rib in the center fuel tank was mislocated, resulting in an offset between the fitting assembly and the refuel/defuel tube assembly. This AD requires modification of the fuel pipe bracket assembly, including all related investigative actions and corrective actions, if necessary; and performing an operational test of the refuel and defuel system. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 months after the effective date of this AD: Perform a modification of the fuel pipe bracket assembly and refuel tube assembly; do all related investigative actions and applicable corrective actions; and perform an operational test of the refuel and defuel system; in accordance with paragraphs 2.B. and 2.C. of the Accomplishment Instructions of Bombardier Service Bulletin 700-28-6006, dated June 1, 2020. All related investigative and corrective actions must be done before further flight.
