Airworthiness Directive 2018-23-08
one-timeAirworthiness Directives; Airbus SAS Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes. This AD was prompted by reports of dual flight management system (FMS) resets with the loss of flight plan (F-PLN) data. This AD requires revising the airplane flight manual (AFM) to prohibit required navigation performance-authorization required (RNP-AR) operations using flight management guidance envelope computer (FMGEC) standard P5H3. This AD would also require modifying the FMS software of airplanes equipped with FMGEC standard P5H3. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2018-23-08 applies to
Applies to all manufacturer serial numbers.
Whether AD 2018-23-08 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.
