Airworthiness Directive · Amendment 39-19481 · Fire protection
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers 9001 through 9839 inclusive, and serial number 9998.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports that non-conforming FIREX squib wire harness connectors may have been installed, which could result in FIREX squib wire harness connectors being connected to the wrong FIREX bottle connectors on affected aircraft. This AD requires a visual inspection of the connections between the FIREX squib wire harness connectors and FIREX bottle connectors, installation of split ring lanyards on the FIREX squib wire harness connectors, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Within 1,000 flight hours or 15 months, whichever occurs first, after the effective date of this AD, perform a visual inspection for correct connections between the FIREX squib wire harness connectors and FIREX bottle connectors, and install split ring lanyards on the FIREX squib wire harness connectors, in accordance with the Accomplishment Instructions of the applicable service information listed in figure 1 to paragraph (g) of this AD. If any incorrect connections are found: Before further flight, re-connect the connectors to the appropriate mating connecters and do an operational test of the fire extinguishing system, in accordance with the Accomplishment Instructions of the applicable service information specified in figure 1 to paragraph (g) of this AD.
