Freighter, 300, and 900 series airplanes; and Model A340200, 300, 500, and 600 series airplanes. This AD was prompted by a report that during the frame of flight test clearance process, a detailed analysis of air data reference ADR failure scenarios led to the identification that compliance requirements for loads and handling qualities throughout the flight envelope could be impaired in case of dispatch with one ADR inoperative master minimum equipment list MMEL item 341001 during the maximum interval allowed by the current MMEL. This AD
requires revising the operators existing FAA-approved minimum equipment list MEL for the air data/inertial reference system, as specified in a European Union Aviation Safety Agency EASA
AD, which is incorporated by reference.
The FAA is issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective January 5, 2022.

200, 200 Freighter, 300, and 900
series airplanes; and Model A340200, 300, 500, and 600 series airplanes.
The NPRM published in the Federal Register on July 28, 2021 86 FR 40373.
