What to do
Operators of affected Pacific Aerospace 750XL aircraft must inspect the wing leading edge skin at the wing root following the procedures in Mandatory Service Bulletin PACSB/XL/091 issue 3 or later. If chafing is found, repairs per Parts A and B of the service bulletin must be completed before further flight; if no chafing is found, Part B requirements must still be completed before further flight. Compliance is required at the next scheduled maintenance inspection or by 22 April 2018, whichever is later.
Summary
Airworthiness Directive DCA/750XL/25A Wing Leading Edge Tank Abrasion - Inspection is issued by the Civil Aviation Authority of New Zealand and applies to Pacific Aerospace 750XL aircraft with serial numbers up to and including 135, except S/N 113. This directive mandates inspection of the wing leading edge skin to detect abrasion caused by ventilation duct chafing, which could lead to fuel leaks. The inspection must follow the instructions in Mandatory Service Bulletin PACSB/XL/091 issue 3 or later revisions.
What changed
This directive updates the previous AD DCA/750XL/25 by introducing the revised Mandatory Service Bulletin PACSB/XL/091 issue 3, dated 15 March 2018, which includes additional repair information. It requires operators to inspect and, if necessary, repair the wing leading edge to prevent abrasion damage caused by ventilation duct chafing. The update ensures that the latest repair procedures are incorporated into maintenance practices.
Why it matters
This directive is critical for aviation professionals because abrasion damage to the wing leading edge can cause fuel leaks, posing a significant safety risk. Operators, maintenance organizations, and compliance teams must ensure inspections and repairs are performed timely to maintain aircraft airworthiness and regulatory compliance. Failure to comply could result in unsafe flight conditions and regulatory penalties.
