An IndiGo Airlines A320 aircraft VT-IEU operating scheduled flight 6E031 from Delhi to Kathmandu was involved in a right main landing gear fire incident during parking at Kathmandu. There were 182 persons on board the aircraft including six crew members.
The flight from Delhi to Kathmandu was uneventful. After landing at Kathmandu the aircraft taxied normally to the bay. After the aircraft was parked on the bay no.5 and the engines were switched off the ground engineer observed smoke from the right main landing gear. The engineer on headset informed the pilot about the smoke from the right main landing gear and advised to evacuate.
The pilot in command instructed the cabin crew in charge via the passenger announcement system to evacuate passengers on the right hand side.
The cabin crew in-charge followed the instructions of pilot and instructed evacuation from the right. The right side main door cabin slides and left over wing slides were deployed by cabin crew. However the cabin crew could not manage the passengers and the passengers evacuated the aircraft along with their cabin hand baggage. Other than a few superficial injuries which occurred during evacuation there was no injury to the passengers.
The fire had occurred after the aircraft was parked on the bay as the hydraulic fluid from the RH main landing gear had leaked from the Quick Release Connectors (QAD) of the no.4 wheel brake system under high pressure and came in contact with hot brakes which eventually resulted into fire.

Probable cause of the Incident: "As the operating hydraulic pressure is very high, the scratches/metal gauging marks in the connector plug/sleeve gave way to the hydraulic fluid. After the hydraulic fluid came in contact with hot brakes smoke was generated and subsequently fire.
The scratches/metal gauging marks in the inter diameter of QAD connector had probably occurred due over torque during maintenance."
