Loss of the Brake Accumulator Pressure pada Pesawat Airbus A330-300

Abstract

This research aims to identify the causes and solutions for cases of loss brake accumulator pressure on the Airbus A330-300 aircraft. The brake accumulator is a component of the brake system, serving as a source of hydraulic power for emergency operations, absorbing pressure spikes, providing temporary power supply during pump failures, and maintaining pressure in the hydraulic system during certain periods or when the pump is not functioning. This is crucial for the brake system in the event of hydraulic system failures. The occurrence of one error, namely loss brake accumulator pressure, was identified when indications in the cockpit showed that the loss brake accumulator pressure. Subsequently, troubleshooting was conducted referring to the aircraft maintenance manual. The causes loss of pressure were identified as damage to the accumulator. The solution to the case loss of brake accumulator pressure can be achieved by replacing the accumulator due to exceeding its designated service life.
