What to do

Operators must perform the functional test within 19 months from the effective date of 31 August 2019 and repeat the test every 4,000 flight hours thereafter. If the reservoir pressure does not reach 3.5 bars during testing, the affected hydraulic pipes must be identified and repaired or replaced before the next flight. Additionally, all test results and repairs must be reported to Airbus within 30 days.

Summary

EASA Airworthiness Directive 2019-0190 is an airworthiness directive issued by EASA concerning Airbus A300 aeroplanes. It mandates functional tests of the hydraulic reservoir air pressurization system lines to detect potential ruptures that could lead to hydraulic fluid contamination and system failure.

What changed

This new directive introduces repetitive functional tests of the reservoir air pressurization lines for the three hydraulic circuits (green, yellow, and blue) on Airbus A300 aircraft. It requires corrective actions such as repair or replacement of hydraulic pipes if leaks are detected during testing.

Why it matters

This directive is critical for maintaining the safety and continued airworthiness of Airbus A300 aircraft by preventing hydraulic fluid contamination and potential hydraulic system loss. Operators and maintenance organizations must comply to avoid reduced aircraft control and ensure regulatory compliance.
