The European Aviation Safety Agency (EASA) has issued an Emergency Airworthiness Directive (AD) requiring the inspection of portable oxygen cylinders in certain overhead stowage compartments of Airbus A300-600 and A310 aircraft.
During maintenance, an operator found that one portable oxygen cylinder assembly had slipped from its bracket inside a one-frame overhead stowage compartment located near door L1. The investigation results indicated that the cylinder assembly had fallen behind the compartment through a cut-out on the comparments’ outboard panel and damaged some electrical wires, resulting in arcing, melted wires, partial burn stains on the and on the cylinder assembly inside of the fuselage.
This condition, if not detected and corrected, could possibly result in an uncontrolled fire in the affected area.
Therefor EASA issued the Emergency Airworthiness Directive (AD), requiring a detailed visual inspection of portable oxygen cylinder assemblies located in one-frame overhead stowage compartments of Airbus A300-600 and A310 aircraft.
