EASA AD DCA-750XL-39
Fuel Condition Lever — Inspection
Summary
Airworthiness Directive DCA/750XL/39 is issued by the Civil Aviation Authority of New Zealand and applies to Pacific Aerospace Limited 750XL aircraft with serial numbers 101 through 216, 220, 8001, and 8002. This directive mandates inspection and adjustment of the fuel condition lever to prevent inadvertent movement into the cut-off position when ground idle is selected. The directive references Pacific Aerospace Mandatory Service Bulletin PACSB/XL/111 issue 1 dated 18 June 2019 for detailed instructions.
What Changed
DCA/750XL/39 introduces a mandatory inspection and adjustment procedure for the fuel condition lever on specified Pacific Aerospace 750XL aircraft. It requires ensuring the fuel condition lever rests against the left side of the control guide slot when set to ground idle to prevent accidental fuel shut-off. This is a new regulation prompted by accident investigation findings.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk where the fuel condition lever could inadvertently move to the cut-off position during flap operation, potentially causing engine shutdown. Compliance helps operators and maintenance teams prevent unsafe conditions and ensures continued airworthiness of affected aircraft. It also supports regulatory compliance and reduces the risk of accidents related to fuel control lever mispositioning.
What To Do
Operators of Pacific Aerospace 750XL aircraft with the specified serial numbers must inspect and adjust the fuel condition lever according to the instructions in Pacific Aerospace Mandatory Service Bulletin PACSB/XL/111 issue 1 or later approved revisions. This must be completed within the next 150 hours time in service or at the next maintenance inspection, whichever occurs later. Documentation of compliance should be maintained as per regulatory requirements.
