EASA AD DCA-750XL-24A
Pitot Static Tube Support Clamps - Inspection
Summary
Airworthiness Directive DCA/750XL/24A Pitot Static Tube Support Clamps - 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 220. This directive mandates inspection and corrective actions on the pitot static tube support clamps to prevent chafing at the flame arrestor intersection. Compliance is required to ensure continued airworthiness and safety of the affected aircraft.
What Changed
This directive introduces a mandatory inspection and corrective action requirement based on Pacific Aerospace Service Bulletin PACSB/XL/094 issue 2 dated 20 March 2018. It revises the previous directive DCA/750XL/24 by updating inspection information and incorporating the revised service bulletin. The change addresses identified insufficient clearance between the pitot static tubes and their primary support.
Why It Matters
The directive is critical for aviation professionals as it addresses a potential unsafe condition that could affect flight safety by preventing damage to pitot static tubes. Operators, maintenance organizations, and compliance teams must ensure inspections are performed to avoid operational disruptions and regulatory non-compliance. Timely adherence reduces risk of in-flight instrument failure related to pitot static system integrity.
What To Do
Operators of Pacific Aerospace 750XL aircraft with serial numbers up to 220 must perform the inspection and any necessary corrective actions as specified in Pacific Aerospace Service Bulletin PACSB/XL/094 issue 2 or later approved revisions. This must be done at the next 300-hour maintenance inspection or by 22 April 2018, whichever occurs first, unless already completed. Compliance with this directive is mandatory before further flight.
