EASA AD DCA-750XL-20
AFM Change - Fuel Tank Caps - Inspection
Summary
The Airworthiness Directive DCA/750XL/20 Fuel Tank Caps - Inspection issued by the Civil Aviation Authority of New Zealand mandates inspections and operational limitations for Pacific Aerospace 750XL aircraft fitted with fuel tank caps P/N 457-1015-12. This directive addresses potential unsafe conditions related to fuel tank caps that may cause fuel loss. It requires amendments to the Pilot’s Operating Handbook and specific inspections to ensure fuel tank cap conformity.
What Changed
This new Airworthiness Directive introduces mandatory revisions to the Pacific Aerospace 750XL Pilot’s Operating Handbook to include a CAA Limitation Section and requires inspection of fuel tank caps P/N 457-1015-12 following Pacific Aerospace Mandatory Service Bulletin PACSB/XL/089. Non-conforming fuel tank caps must be replaced with P/N 11-21087-1 caps before further flight, and the limitation section removed upon replacement.
Why It Matters
This directive is critical for operators and maintenance personnel to prevent fuel loss due to defective fuel tank caps, which could compromise flight safety. Compliance ensures that fuel tank caps are properly locked and sealed, reducing the risk of fuel leakage during flight. It also affects operational planning, as ferry and oceanic flights are prohibited until inspections are completed.
What To Do
Operators must amend the Pacific Aerospace 750XL Pilot’s Operating Handbook immediately to include the CAA Limitation Section. By 31 January 2018, they must inspect all fuel tank caps P/N 457-1015-12 according to the specified service bulletin and replace any defective caps with P/N 11-21087-1 before further flight. The limitation section should be removed from the handbook once defective caps are replaced.
