Flight Overview
On April 26, 2025, Jet2 flight LS-622, operated by a Boeing 737-800 aircraft registered as G-JZBC, departed from Dalaman Airport (DLM), Turkey, bound for East Midlands Airport (EMA), United Kingdom. The flight was carrying 184 passengers and crew members. Approximately two hours and nineteen minutes into the flight, while cruising at an altitude of 36,000 feet over Serbian airspace, the flight crew observed an abnormal indication related to the left engine’s oil system, prompting a diversion to Budapest Ferenc Liszt International Airport (BUD), Hungary.
Aircraft and Crew Information
The aircraft involved, G-JZBC, is a Boeing 737-800 equipped with two CFM56-7B engines. At the time of the incident, the aircraft had been in service for approximately seven years. The flight crew comprised experienced pilots, both holding valid licenses and medical certificates, with no reported issues in their recent duty periods. The cabin crew were also appropriately certified and had completed all requisite training modules.
Sequence of Events
Cruise Phase: While cruising at FL360 over Serbian airspace, the flight crew received an engine oil pressure warning for the left engine (Engine No. 1). The oil quantity indication showed a decreasing trend, suggesting a potential leak. Decision to Divert: Following standard operating procedures, the crew assessed the situation and decided to divert to the nearest suitable airport. Budapest Ferenc Liszt International Airport was identified as the optimal diversion point due to its proximity and facilities. Descent and Landing: The aircraft commenced a descent towards Budapest, coordinating with air traffic control for a priority landing. The flight crew managed the descent and approach without further incident, landing safely on runway 31R approximately 30 minutes after the decision to divert.
Post-Landing Actions
Upon landing, the aircraft was met by emergency services as a precautionary measure. Passengers were disembarked normally, and no injuries were reported. Maintenance teams conducted an initial inspection, confirming an oil leak in the left engine. The aircraft was subsequently grounded for detailed examination and repairs.
Maintenance and Investigation
Jet2’s engineering team, in collaboration with CFM International, initiated a thorough investigation to determine the cause of the oil leak. Preliminary findings indicated a failure in the oil supply line, leading to a gradual loss of oil pressure. The affected components were replaced, and the engine underwent rigorous testing before the aircraft was cleared for a positioning flight to Manchester Airport (MAN), United Kingdom.
Operational Impact
The diversion resulted in a delay for passengers, who were accommodated in Budapest overnight. A replacement aircraft, another Boeing 737-800 registered as G-DRTX, was dispatched to complete the journey to East Midlands Airport, arriving approximately 16 hours behind schedule. Jet2 provided necessary support to affected passengers, including meals and accommodation.
Safety and Regulatory Considerations
The incident underscores the importance of real-time monitoring systems and prompt decision-making by flight crews. The successful diversion and safe landing highlight the effectiveness of Jet2’s training programs and emergency protocols. The Civil Aviation Authority (CAA) and the European Union Aviation Safety Agency (EASA) were notified, and findings from the investigation will contribute to ongoing safety enhancements.
Conclusion
Jet2 flight LS-622’s diversion to Budapest due to an engine oil leak was managed effectively, with no injuries or further complications. The incident serves as a testament to the robustness of aviation safety systems and the professionalism of airline personnel in handling in-flight anomalies.
