Ryanair Flight FR1879 From Thessaloniki to Memmingen Faces Major Mid-Air Emergency as Boeing 737-800 Engine Failure Leads to Cabin Decompression, and Window Damage Before Safe Return to Greece: Latest Update

Ryanair Flight FR1879 operating from Thessaloniki, Greece, to Memmingen, Germany, was forced to return to Thessaloniki Airport after a serious technical emergency developed shortly after take-off, involving an engine failure, cabin decompression and damage to a passenger window area. The Boeing 737-800 aircraft, operated by Ryanair Group subsidiary Malta Air, safely completed an emergency landing after pilots stabilised the aircraft and returned to its departure airport.

The incident occurred on 10 July 2026 during the early stage of the scheduled European flight. The aircraft had only been airborne for several minutes when the emergency developed while climbing over the border region between northern Greece and North Macedonia.

The event created a major disruption for passengers travelling between Greece and southern Germany, but the controlled response by the flight crew prevented further escalation. A replacement aircraft was later arranged, allowing passengers to continue their journey to Memmingen.

Boeing 737-800 Experienced Engine Problem During Climb From Thessaloniki

Flight FR1879 was operated using a Boeing 737-8AS aircraft, part of the Boeing 737 Next Generation family. The aircraft was registered as 9H-QEU and operated by Malta Air, which forms part of the wider Ryanair aviation group. The aircraft departed Thessaloniki International Airport “Makedonia” during the morning for its scheduled flight to Memmingen Airport in Bavaria, Germany.

According to flight tracking information, the aircraft climbed rapidly after departure and reached an altitude of approximately 15,000 to 16,000 feet before the emergency occurred. During this phase, the aircraft experienced a serious issue involving the right-side engine.

The aircraft was powered by CFM International CFM56-7B engines, widely used on Boeing 737 Next Generation aircraft. Investigators are examining the engine components to determine the exact cause of the failure and whether any technical or maintenance factors contributed.

Cabin Decompression Occurred After Aircraft Damage

Following the engine-related event, debris from the affected area caused damage to the aircraft structure, including the passenger window section. The sudden damage resulted in a rapid change in cabin pressure. Oxygen masks were released inside the cabin as passengers experienced the effects of decompression. A passenger seated beside the affected window area suffered injuries during the incident.

The 61-year-old Serbian passenger was taken to AHEPA University General Hospital in Thessaloniki after the emergency landing. Medical updates indicated that the injuries were not life-threatening. The passenger received treatment for shock, injuries around the neck and shoulder area, and friction-related injuries caused during the decompression event. No other serious passenger injuries were reported.

Pilots Execute Emergency Return to Thessaloniki Airport

The aircraft crew responded immediately after the emergency was detected. The pilots declared an emergency, reduced altitude and turned the aircraft back towards Thessaloniki. Because the aircraft had departed with a significant amount of fuel required for the journey to Germany, it remained at a lower altitude while preparing for a safe return. The aircraft entered a holding pattern over the Thermaic Gulf area south of Thessaloniki to reduce weight before landing.

The aircraft eventually completed a safe landing at Thessaloniki Airport approximately 56 minutes after departure. Emergency teams were positioned to support the aircraft after arrival. Passengers were removed from the aircraft and transferred back to the terminal while safety inspections began.

Replacement Aircraft Restores Greece–Germany Passenger Connection

The incident temporarily interrupted the travel plans of passengers heading from Greece to Germany. Ryanair arranged a replacement Boeing 737-800 aircraft to complete the journey. Passengers were transferred to the replacement aircraft later the same morning. The aircraft departed Thessaloniki several hours after the original scheduled departure and arrived safely at Memmingen Airport.

The disruption affected travellers with onward transport arrangements in Germany, including airport transfers, regional rail connections and accommodation plans. Such incidents often highlight the importance of allowing additional time when travelling through airports, especially when connecting to other services.

Investigation Begins With Support From Aviation Authorities

The investigation into the incident is being coordinated by aviation safety authorities because the aircraft was operating in the region of North Macedonian airspace when the emergency occurred. The investigation team is examining multiple elements, including engine components, aircraft structure, operational data, maintenance history and technical records.

International aviation organisations and aircraft specialists are supporting the inquiry, including the European Union Aviation Safety Agency, the US Federal Aviation Administration, the National Transportation Safety Board and Boeing. Investigators will determine whether the event was caused by mechanical failure, component damage, maintenance-related factors or another technical issue.

Aircraft Remains Grounded for Detailed Safety Inspection

The affected Boeing 737-800 aircraft remains grounded in Thessaloniki while specialists conduct a complete technical examination. The inspection is focused on the right-side engine, engine casing, damaged aircraft structure and cabin window area. Engineers will analyse the aircraft to determine whether repairs can be completed or whether additional action is required.

The aircraft entered service with Ryanair in 2008 and was approximately 18 years old at the time of the incident. Aircraft age alone does not determine safety performance, as commercial aircraft undergo regular inspections, maintenance programmes and regulatory checks throughout their operational life.

For passengers travelling between Greece and Germany, the incident ended with a safe return, medical assistance for the injured traveller and the continuation of the journey through replacement operations. The final investigation report will provide the complete technical explanation behind the emergency involving Ryanair Flight FR1879.
