EASA AD 2022-0116
Hydraulic Power — Hydraulic System Reservoirs Pressurization — Functional Check
Summary
EASA Airworthiness Directive 2022-0116 is an airworthiness directive addressing hydraulic system reservoir pressurization on Airbus A300B2-203, A300B2K-3C, A300B4-203, A300B4-2C, A300C4-203, and A300F4-203 aeroplanes. It mandates functional checks of the hydraulic system reservoirs to detect air leakage and ensure proper pressurization. The directive aims to prevent potential loss of hydraulic systems due to contamination and air pressurization line rupture.
What Changed
EASA Airworthiness Directive 2022-0116 introduces a new requirement for repetitive functional checks of the pressurization of all three hydraulic system reservoirs on affected Airbus A300 models. It also requires corrective actions if discrepancies are found and mandates reporting of inspection results to Airbus. This directive does not supersede any previous ADs.
Why It Matters
This directive is critical for aviation professionals because contamination in the hydraulic reservoir pressurization system can lead to hydraulic system failure and potential loss of aircraft control. Operators and maintenance teams must ensure compliance to maintain aircraft safety and airworthiness. Timely detection and correction of issues help prevent costly repairs and operational disruptions.
What To Do
Operators of affected Airbus A300 models must perform the initial functional check of the hydraulic system reservoir pressurization within 30 months of 5 July 2022 and repeat the check every 4,000 flight hours thereafter. Any discrepancies found during checks must be corrected before the next flight. Additionally, inspection results must be reported to Airbus within 30 days after the first check and after subsequent checks only if findings are present.
