EASA AD 2022-0147
SUPERSEDED BY EASA AD 2024-0196
Summary
EASA Airworthiness Directive 2022-0147 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus A318, A319, A320, and A321 aeroplanes. It addresses potential defects in certain overheat detection system (OHDS) sensing elements manufactured before 31 January 2021, which may fail to detect thermal bleed leak events properly. The directive mandates inspection and possible replacement of these affected parts to ensure continued airworthiness.
What Changed
EASA Airworthiness Directive 2022-0147 introduces a one-time special detailed inspection of OHDS sensing elements installed at specific positions on affected Airbus A318, A319, A320, and A321 models. It requires replacement of any sensing element found with discrepancies and prohibits installation of affected parts after the effective date. This AD corrects the document type in the header and provides detailed instructions for compliance.
Why It Matters
This directive is critical for aviation professionals because undetected thermal bleed leaks could lead to high temperatures in the main landing gear bay and keel beam areas, potentially compromising structural integrity. Operators and maintenance organizations must ensure compliance to prevent safety risks and maintain regulatory approval for aircraft operation. It also impacts parts management by restricting installation of affected components.
What To Do
Operators of affected Airbus A318, A319, A320, and A321 aeroplanes must perform a special detailed inspection of the OHDS sensing elements within 72 months from 28 July 2022. Any sensing element showing discrepancies must be replaced before the next flight. Additionally, no affected parts may be installed on any aircraft from the effective date onward.
