Airworthiness Directive · Amendment 39-18521 · Fuel
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes, certificated in any category, serial numbers 5906, 5910, 5912, 5917, 5919 through 5932 inclusive, 5934, 5935, 5939, 5940, 5942, and 5948.
We are superseding Airworthiness Directive (AD) 2014-20-01 for certain Bombardier, Inc. Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. AD 2014-20-01 required repetitive inspections for any fuel leak in the right-hand landing lights compartment, and related investigative and corrective actions if necessary. AD 2014-20-01 also provides for an optional replacement of the connector of the fuel boost pump canister of the auxiliary power unit (APU), which terminates the repetitive inspections. This new AD requires replacing the connector of the fuel boost pump canister of the APU. This AD was prompted by the determination that a terminating action for the repetitive inspections is necessary. We are issuing this AD to detect and correct fuel leaks in the right-hand landing lights compartment, which, in combination with the heat generated by the taxi lights and landing lights on the ground reaching the auto-ignition temperature of the fuel, could result in ignition of any fuel or fumes present in the right-hand landing lights compartment.
This paragraph restates the requirements of paragraph (g) of AD 2014-20-01, with no changes. Within 25 flight hours after October 20, 2014 (the effective date of AD 2014-20-01): Do a general visual inspection for any fuel leak in the right-hand landing lights compartment, and do all applicable related investigative and corrective actions, in accordance with Part A of the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, Revision 02, dated July 9, 2014, except as required by paragraph (h) of this AD. Do all applicable related investigative and corrective actions before further flight. Repeat the inspection thereafter at intervals not to exceed 8 flight hours until the replacement specified in paragraph (j) of this AD has been accomplished.
This paragraph restates the requirements of paragraph (h) of AD 2014-20-01, with no changes. If any fuel leak is found during the related investigative actions required by paragraph (g) of this AD: Before further flight, do the terminating action specified in paragraph (j) of this AD, or do corrective actions using a method approved by the Manager, New York Aircraft Certification Office (ACO), ANE-170, FAA; or Transport Canada Civil Aviation (TCCA); or Bombardier, Inc.'s TCCA Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
This paragraph restates the requirements of paragraph (j) of AD 2014-20-01, with no changes. For airplanes having new connectors installed, as specified in Part B of the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, dated April 21, 2014: Within 6 months or 150 flight hours after October 20, 2014 (the effective date of AD 2014-20-01), whichever occurs first, do a detailed inspection for damage (cuts) of the connector wiring, in accordance with Part B of the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, Revision 02, dated July 9, 2014. If any damage (cuts) is found on the wires, before further flight, replace the wire with a new wire identified in kit 605K28-008A, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, Revision 02, dated July 9, 2014.
Within 6 months, or 150 flight hours, whichever occurs first, after the effective date of this AD, replace the connector of the fuel boost pump canister of the APU and do all applicable related investigative actions, in accordance with Part B of the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, Revision 02, dated July 9, 2014. Accomplishing this replacement terminates the repetitive actions required by paragraph (g) of this AD, provided that the following actions are done, as applicable.
(1) If any damage (cuts) is found on the wires, before further flight, replace the wire with a new wire identified in kit 605K28-008A, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, Revision 02, dated July 9, 2014.
(2) If any damage is found on an O-ring, before further flight, replace the O-ring with a new O-ring, in accordance with the Accomplishment Instructions of Bombardier Alert Service Bulletin A605-28-008, Revision 02, dated July 9, 2014.
(3) If any fuel leak is found, before further flight, do corrective actions using a method approved by the Manager, New York ACO, ANE-170, FAA; or TCCA; or Bombardier, Inc.'s TCCA DAO. If approved by the DAO, the approval must include the DAO-authorized signature.
This paragraph restates paragraph (k) of AD 2014-20-01, with a revised paragraph reference. This paragraph provides credit for actions required by paragraph (j) of this AD, if those actions were performed before October 20, 2014 (the effective date of AD 2014-20-01), using Bombardier Alert Service Bulletin A605-28-008, Revision 01, dated May 28, 2014, which is not incorporated by reference in this AD.
