Airworthiness Directive · Amendment 39-17919 · Fuel
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes, certificated in any category, serial numbers 5301 through 5665 inclusive, and 5701 and subsequent.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This AD requires revising the airplane flight manual to incorporate temporary revisions that introduce additional limitations for operation of taxi and landing lights. This AD was prompted by a determination that there is a potential for fuel leakage from auxiliary power unit (APU) boost pump component installations in the right-hand landing lights compartment. We are issuing this AD to advise the flightcrew of the limitations for taxi lights and landing lights to prevent heat generated by the taxi lights and landing lights on the ground reaching the auto-ignition temperature of the fuel, which could potentially ignite any fuel or fumes present in the right-hand landing lights compartment.
Within 24 hours after the effective date of this AD, revise the AFM to incorporate the applicable temporary revisions (TRs) specified in paragraphs (g)(1) and (g)(2) of this AD. Operate the airplane according to the procedures in the TRs specified in paragraph (g)(1) or (g)(2) of this AD, as applicable. The AFM revision required by paragraph (g) of this AD may be done by inserting a copy of TR 604/38, Taxi and Landing Lights, dated June 16, 2014, into the Bombardier Challenger CL-604 AFM, PSP 604-1; or a copy of TR 605/20, Taxi and Landing Lights, dated June 16, 2014, into the Bombardier Challenger CL-605 AFM, PSP 605-1. When these TRs have been included in the general revisions of the applicable AFM, the general revisions may be inserted in the AFM and the TRs may be removed, provided the relevant information in the general revision is identical to that included in TR 604/38, Taxi and Landing Lights, dated June 16, 2014; or TR 605/20, Taxi and Landing Lights, dated June 16, 2014; as applicable.
(1) TR 604/38, Taxi and Landing Lights, dated June 16, 2014, to the Bombardier Challenger CL-604 AFM, PSP 604-1 (for Bombardier Model CL-600-2B16 (604 Variant) airplanes, serial numbers 5301 through 5665 inclusive).
(2) TR 605/20, Taxi and Landing Lights, dated June 16, 2014, to the Bombardier Challenger CL-605 Airplane Flight Manual PSP 605-1 (for Bombardier Model CL-600-2B16 (604 Variant) airplanes, serial numbers 5701 and subsequent).
