EASA AD 2024-0196
Pneumatic — Overheat Detection System Sensing Elements — Inspection
Summary
EASA Airworthiness Directive 2024-0196 is an airworthiness directive addressing the inspection of pneumatic overheat detection system sensing elements on Airbus A318, A319, A320, and A321 aeroplanes. It applies to specific part numbers of continuous fire detectors produced before January 31, 2021, which may fail to detect thermal bleed leak events properly. The directive mandates inspection and, if necessary, replacement of affected parts to ensure continued airworthiness.
What Changed
EASA AD 2024-0196 supersedes the previous AD 2022-0147 and extends its applicability to include the newly certified Airbus A321-253NY model. It retains the inspection and replacement requirements from the prior AD and prohibits installation of affected parts on all applicable aircraft models from the effective date. No additional inspection actions are required for aircraft already compliant with the previous AD.
Why It Matters
This directive is critical for aviation professionals because it addresses a potential safety risk where faulty overheat detection elements could fail to detect air leaks, leading to high-temperature exposure and possible structural damage. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and regulatory conformity. Failure to comply could result in unsafe flight conditions and regulatory penalties.
What To Do
Operators of affected Airbus A318, A319, A320, and A321 aircraft must perform a special detailed inspection of the overheat detection system sensing elements within 72 months after July 28, 2022, if not already done. Any defective parts found must be replaced before the next flight. From November 1, 2024, installation of affected parts at specified positions is prohibited on all affected aircraft models.
