EASA AD 2021-0210
Aircraft Flight Manual — Take-off Distance with Crosswind above 20 Knots — Amendment
Summary
EASA Airworthiness Directive 2021-0210 is an amendment addressing the Airbus A330-841 and A330-941 aeroplanes. It mandates an update to the Aircraft Flight Manual to correct take-off distance calculations when crosswinds exceed 20 knots. This directive ensures accurate performance data is used for safe aircraft operation under these conditions.
What Changed
This directive introduces a correction to the aircraft performance database used in the Airbus A330 Aircraft Flight Manual for crosswinds above 20 knots. The update fixes previously incorrect take-off distance computations caused by not accounting for the thrust setting procedure in such crosswind conditions. Operators must incorporate the specified AFM Documentary Unit revisions into their manuals.
Why It Matters
Accurate take-off performance data is critical for safe flight operations, especially in challenging crosswind conditions. Incorrect computations could lead to runway overruns during take-off, particularly following engine failure or rejected take-off scenarios. Compliance with this directive helps prevent potential damage to the aircraft and injury to occupants by ensuring flight crews have reliable performance information.
What To Do
Operators of Airbus A330-841 and A330-941 aircraft must update their Aircraft Flight Manuals by incorporating the specified AFM Documentary Unit within 30 days of the directive's effective date. Flight crews must be informed of the update and operate the aircraft according to the revised performance data. Using later approved AFM revisions that include the update is also acceptable for compliance.
