Superseded. A later AD replaced this one: AD 2001-02-05. Comply with the one in force.
CL-604 variant of Canadair Model CL-600-2B16 series airplanes modified in accordance with Supplemental Type Certificate SA8060NM-D, SA8072NM-D, or SA8086NM-D; certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been otherwise modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2000-01-51 that was sent previously by individual notices to all known U.S. owners and operators of Model CL-604 variant of Bombardier Model Canadair CL-600-2B16 series airplanes modified in accordance with Supplemental Type Certificate SA8060NM-D, SA8072NM-D, or SA8086NM-D. This AD requires that the fuel service panel maintenance light be disconnected. This action is prompted by a report indicating that an electrical spark was noted when the fuel cap chain contacted the maintenance light housing of the fuel service panel. The actions specified by this AD are intended to prevent electrical sparks from a grounded object from coming into contact with the maintenance light housing of the fuel service panel, which could result in a fuel fire due to the close proximity of the fuel service panel to the fuel port.
To prevent a fuel fire due to electrical sparks contacting the maintenance light housing of the fuel service panel, accomplish the following:
(a) Within 48 hours after the effective date of this AD, perform the actions specified in paragraphs (a)(1), (a)(2), (a)(3), (a)(4), (a)(5), (a)(6), and (a)(7) of this AD.
(1) Open and lock-out the circuit breaker CB5-B8 located in the aft equipment bay at STA.645L on the JB5 panel.
(2) Open the refuel/defuel door located on the right side of the fuselage at the wing root. Remove the maintenance light receptacle by removing the four screws holding the receptacle to the fairing.
(3) Pull the light receptacle away from the fairing revealing the two wire leads attached to the receptacle.
(4) Disconnect the wires by removing the two screws that attach the wire leads to the light receptacle.
(5) Cap and stow the wires to prevent contact with metal objects within the fairing.
(6) Re-install the light receptacle in the fairing.
(7) Close circuit breaker CB5-B8.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
