Summary
Airworthiness Directive DCA/750XL/37 Engine Fuel Lines and Electrical Wiring – Inspection is issued by the Civil Aviation Authority of New Zealand and applies to Pacific Aerospace Limited 750XL aircraft, serial numbers 101 through 215, 220, 8001, and 8002 fitted with or configured for an air conditioner and/or a standby alternator. This directive mandates inspection of engine fuel feed line hoses and electrical wiring forward of the engine firewall to detect chafing that could cause fuel leaks and fire. It references Pacific Aerospace Mandatory Service Bulletin PACSB/XL/113 issue 2 for inspection and corrective actions.
What changed
DCA/750XL/37 introduces mandatory inspections and corrective actions to prevent chafing between engine fuel feed lines and electrical wiring or the ignition exciter on affected 750XL aircraft. It requires operators to inspect per the specified service bulletin and repair any damage before further flight. If no damage is found, follow-up inspections and maintenance actions are scheduled within defined flight hour limits.
Why it matters
This directive addresses a critical safety risk of fuel leaks and potential fires caused by chafing of fuel lines against electrical wiring. Aviation professionals, including operators and maintenance organizations, must ensure compliance to maintain airworthiness and prevent hazardous conditions. Timely inspections and repairs reduce the risk of in-flight emergencies and enhance operational safety.
