EASA AD 2024-0151
Aircraft Flight Manual / Complementary Performance Data File — Amendment
Summary
EASA Airworthiness Directive 2024-0151 is an amendment applicable to Airbus A321 aeroplanes, including multiple variants such as A321-111, A321-131, A321-251N, and others. This directive addresses an error in the main landing gear tyre width data used in aircraft performance calculations. The directive mandates updates to the Aircraft Flight Manual and Complementary Performance Data File to correct performance computations.
What Changed
EASA Airworthiness Directive 2024-0151 requires updating the Aircraft Flight Manual and the Complementary Performance Data File with corrected main landing gear tyre width values. This update corrects the aircraft performance database, particularly for contaminated runway conditions, ensuring accurate take-off and accelerate stop distance calculations. The directive introduces these changes to prevent non-conservative performance data.
Why It Matters
This directive is critical for aviation professionals because inaccurate landing gear tyre width data can lead to erroneous performance calculations, increasing the risk of runway excursions. Operators and maintenance teams must ensure compliance to maintain safe aircraft operation under contaminated runway conditions. Accurate performance data is essential for flight crews to make informed decisions during takeoff and landing phases.
What To Do
Operators of affected Airbus A321 models must implement the Complementary Performance Data File update in the Aircraft Flight Manual within three months of the effective date, 14 August 2024. Flight crews must be informed of the update and operate the aircraft accordingly. Incorporating a later Aircraft Flight Manual revision containing the same updates is also acceptable for compliance.
