What to do
Operators of affected Airbus A330 and A340 aircraft must install the diode modification within 24 months from the effective date of 17 April 2020. The installation must follow the instructions provided in the applicable Airbus Service Bulletins A330-25-3733, A340-25-4375, or A340-25-5239. Alternative methods of compliance may be approved by EASA if properly substantiated.
Summary
EASA Airworthiness Directive 2020-0083 is an airworthiness directive addressing Airbus A330 and A340 aeroplanes equipped with certain Emergency Locator Transmitters (ELTs). It applies to specific ELT part numbers installed on these aircraft, excluding those with certain Airbus modifications already embodied. The directive mandates a modification to improve ELT battery protection to prevent potential fire hazards.
What changed
EASA Airworthiness Directive 2020-0083 introduces a mandatory modification requiring the installation of a diode between the affected ELT and the terminal block. This modification addresses a safety concern related to the risk of battery fire caused by current injection on non-rechargeable lithium batteries in the ELTs. The directive references specific Airbus Service Bulletins for the modification procedure.
Why it matters
This directive is critical for aviation professionals as it mitigates a potential fire risk associated with ELT batteries, enhancing aircraft safety and protecting occupants. Operators and maintenance organizations must ensure compliance to maintain airworthiness and avoid operational restrictions. The modification also helps prevent damage to the aircraft and potential injury, aligning with regulatory safety requirements.
