The directive mandates modifications to improve ELT battery current injection protection to prevent potential battery fires.
What Changed
This correction clarifies typographical errors in the original note regarding affected aircraft groups. The directive requires installation of a diode in the ELT battery circuit to prevent current injection issues that could cause battery fires. It introduces specific grouping of aircraft based on the installation of affected parts and previous modifications.
Why It Matters
This directive is critical for aviation professionals as it addresses a safety risk involving potential ELT battery fires, which could lead to damage and injury. Operators and maintenance teams must ensure compliance to maintain airworthiness and avoid operational restrictions. The modification enhances the safety and reliability of ELT systems on affected Airbus aircraft.
What To Do
Operators of Group 1 Airbus A318, A319, A320, and A321 aeroplanes must complete the required modification within 24 months from the effective date of 21 May 2020 by following the applicable Airbus Service Bulletin instructions.
