recurringAirworthiness Directives; Deutsche Aircraft GmbH (Type Certificate Previously Held by 328 Support Services GmbH; AvCraft Aerospace GmbH; Fairchild Dornier GmbH; Dornier Luftfahrt GmbH) Airplanes
What this AD requires
The FAA is superseding Airworthiness Directive (AD) 2024-03- 07, which applied to all Deutsche Aircraft GmbH Model 328-100 and 328- 300 airplanes. AD 2024-03-07 required a one-time detailed inspection of each affected part, and applicable corrective actions. Since the FAA issued AD 2024-03-07, the FAA determined that repetitive inspections are necessary. This AD continues to require the actions in AD 2024-03- 07 and requires repetitive inspections of the affected part. The FAA is issuing this AD to address the unsafe condition on these products.

Whether AD 2025-14439 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
