## Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes. This proposed AD was prompted by reports of dual flight management system (FMS) resets with the loss of flight plan (F-PLN) data. This proposed AD would require 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 proposed AD would also require modifying the FMS software of airplanes equipped with FMGEC standard P5H3. We are proposing this AD to address the unsafe condition on these products.
