EASA AD DCA-750XL-30
Relocation of Ground Terminations — Inspection
Summary
The Airworthiness Directive DCA/750XL/30 Relocation of Ground Terminations – Inspection is issued by the Civil Aviation Authority of New Zealand. It applies to Pacific Aerospace Limited 750XL aircraft, serial numbers up to and including 222, equipped with a main battery located within the engine bay at the firewall. This directive mandates inspection and modification of the aircraft's ground connections for power sources to enhance safety.
What Changed
This new Airworthiness Directive requires separating the ground connections for the individual power sources, specifically the battery (BATT) and generator (GEN), which were previously connected at a common ground point. The directive enforces compliance with Pacific Aerospace Mandatory Service Bulletin PACSB/XL/104 issue 1 or later approved revisions to achieve this separation.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential unsafe condition related to the electrical grounding system of the affected aircraft. Proper separation of ground terminations reduces the risk of electrical faults or failures, thereby enhancing aircraft safety and reliability. Operators, maintenance organizations, and compliance teams must ensure adherence to avoid regulatory violations and maintain airworthiness.
What To Do
Operators of Pacific Aerospace 750XL aircraft with serial numbers up to 222 must inspect and modify the ground connections for the battery and generator according to the instructions in the specified Mandatory Service Bulletin. This work must be completed at the next scheduled maintenance inspection or by 2018-09-05, whichever occurs first.
