Summary
Airworthiness Directive DCA/750XL/22A Ventilation Hose behind Instrument Panel - Inspection is issued by the Civil Aviation Authority of New Zealand and applies to all Pacific Aerospace 750XL aircraft with serial numbers up to and including 220. This directive mandates inspection and potential repair of the ventilation SCAT hose behind the instrument panel to prevent chafing damage to components and wiring. Compliance with the specified Pacific Aerospace Mandatory Service Bulletin PACSB/XL/083 issue 2 is required.
What changed
DCA/750XL/22A supersedes the previous directive DCA/750XL/22 by introducing the updated Pacific Aerospace Mandatory Service Bulletin PACSB/XL/083 issue 2 dated 16 January 2018. The updated service bulletin includes an optional SCAT hose configuration, clarifies mounting instructions for self-adhesive mounts, and recommends using 25mm wide 3M Scotch 27 glass cloth tape to wrap the hose. There are no changes to the applicability of the directive.
Why it matters
This directive is critical for aviation professionals to prevent potential abrasion damage caused by ventilation hose chafing behind the instrument panel, which could compromise aircraft safety. Operators, maintenance organizations, and compliance teams must ensure inspections and repairs are conducted to maintain airworthiness and regulatory compliance. Failure to comply may result in unsafe operating conditions and regulatory penalties.
