Air India Express Flight Returns to Cochin After Engine Shutdown at 36,000 Feet

An Air India Express flight from Cochin to Abu Dhabi was forced to return to its departure airport on [date] after the crew detected a serious engine oil pressure problem mid-flight. The Boeing 737, operating as flight IX 415, was cruising at 36,000 feet when the pilots noticed a rapid drop in oil quantity. When the oil pressure entered the danger zone, they shut down the engine as a precaution.

The technical issue emerged about 50 minutes after take-off. Following standard operating procedures, the crew conducted a structured risk assessment and decided to abandon the journey to Abu Dhabi and head back to Cochin. The commander informed air traffic control via high-frequency radio, and the aircraft changed course.

During the diversion, the crew continued to monitor engine parameters. Approximately 45 minutes after turning back, the oil pressure on Engine 1 began to fluctuate and entered the red zone on the cockpit gauge. The pilots then followed the Non-Normal Checklist and shut down the engine completely.

Landing an overweight Boeing 737 with only one engine operating is a demanding and high-risk manoeuvre, but the crew executed it smoothly. Passengers on board were largely unaware of the seriousness of the situation, and all disembarked safely without any injuries.

The incident adds to a series of technical diversions reported by Indian airlines in recent weeks. It comes shortly after the Aircraft Accident Investigation Bureau released preliminary findings into an earlier Air India Phuket-Delhi incident, which involved hydraulic issues. In that case, technical experts inspected the aircraft and collected hydraulic fluid samples for analysis.

Following the earlier incident, Union Civil Aviation Minister Ram Mohan Naidu announced that the Directorate General of Civil Aviation would increase the annual percentage of psychoactive substance tests for flight crew. The latest engine-oil incident has now raised questions about whether the ministry will also strengthen the framework governing DGCA safety audits.
