## Abstract

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.
