Summary
EASA Airworthiness Directive 2022-0098 is an amendment affecting Airbus A350-941 and A350-1041 aeroplanes equipped with certain flight control software standards. It addresses issues related to the primary flight control computers (PRIM) software that could lead to loss of elevator control. The directive mandates updates to the Aircraft Flight Manual, Master Minimum Equipment List, and installation of a software update to ensure continued safe operation.
What changed
This directive supersedes the previous Emergency AD 2022-0079-E and requires operators to amend the Aircraft Flight Manual and Master Minimum Equipment List with temporary revisions and dispatch restrictions. It also mandates installation of a serviceable PRIM software version P13.1.2 or later within 30 days to correct the unsafe condition caused by incorrect software instructions in the earlier PRIM P13 standard.
Why it matters
The directive is critical for aviation professionals as it prevents potential loss of elevator control, which could lead to loss of aircraft control. Operators and maintenance teams must comply promptly to maintain airworthiness and avoid operational disruptions. Compliance ensures adherence to EASA regulations and maintains safety standards for Airbus A350 aircraft equipped with the affected flight control systems.
