Broken engine parts were responsible for shattering a window on a Ryanair plane, causing a passenger to be partly sucked out mid-flight in July, US investigators have said.
A preliminary report by the National Transportation Safety Board (NTSB) found an engine fan blade broke off shortly after takeoff on the ۱۰ July flight from Greece to Germany shattering the window and damaging the fuselage.
The Serbian entrepreneur Ljubisa Karović, sitting by the window in seat ۱۱F, had his head and right arm sucked out of the broken window in the incident.
Karović was saved from being completely sucked out of the window by other passengers, who grabbed hold of him.
The ۶۱-year-old told the Guardian he was lucky to be alive after the incident on Ryanair flight FR۱۸۷۹ and said his wife, Svetlana, told him he had fainted several times, including after he had been pulled back inside the cabin.
The NTSB said the flight, which was scheduled to fly from Thessaloniki in Greece to Memmingen near Munich, “experienced a No ۲ (right) engine fan-blade-out (FBO) failure during climb out from the Thessaloniki international airport (SKG)”. The flight was operated by the budget airline’s subsidiary Malta Air.
Investigators found the cabin depressurised and the two pilots decided to return to Thessaloniki airport, where they “made an uneventful landing”.
A few days after the incident, the NTSB was “delegated the investigation in full” by the Greek authorities. The flight crew’s timeline of the event was set out by the NTSB, detailing how they experienced a “high vibration” engine alert during the flight climb. They reduced the engine power in response and carried out a series of checks.
The engine vibration reduced and the crew continued the climb on autopilot. However, the vibrations then increased significantly and the crew heard a loud bang. The flight crew put on their oxygen masks, declared an emergency and began an immediate descent.
The flight attendants reported “hearing and feeling a loud continuous vibration and seeing a small amount of fog/smoke before the oxygen masks dropped”, the report found.
Four bird strikes to the plane’s right engine were reported by flight crews in the ۱۲ months preceding the incident, the report found, adding that bird remains were reportedly found in two of the cases. The fan blades had undergone ultrasonic inspections in recent months with “no findings”.
Karović told the Guardian less than a fortnight after the incident that he did not remember much but had a painful head and neck. “It could have been the seatbelt, the fact that I was still strapped in. But maybe it is fate. I believe in God and I thank him every day,” he said.
The Boeing ۷۳۷-۸۰۰ plane had ۱۴۹ passengers and four flight attendants on board.
Ryanair said it would not comment on the preliminary report, or on whether Karović would receive compensation, until after the final report was published.

The airline’s finance chief said last month it was “way too early” to discuss whether Ryanair would have to compensate the couple while the airline awaited the outcome of an investigation into the incident.
Boeing and CFM, the engine maker, are assisting with the investigation.
Jeff Guzzetti, a former NTSB and Federal Aviation Administration (FAA) investigator who reviewed the preliminary report, told the Associated Press that the required maintenance appears to have been performed on schedule.
However, investigators are expected to examine how the previous inspections were conducted and whether the previous suspected bird strikes contributed to pre-existing damage. “We know what happened and even to some extent why it happened, but there’s still unanswered questions that the NTSB will get at,” Guzzetti said.
In ۲۰۲۵ the FAA issued three directives requiring airlines to strengthen parts of the engine coverings on Boeing ۷۳۷ planes, following two previous fan blade failures that sent pieces of the engine covering flying. In one accident, a passenger was killed on a Southwest Airlines plane in ۲۰۱۸, after debris knocked out a window.
The FAA gave airlines until July ۲۰۲۸ to complete the modifications, and the NTSB report found the required changes had not yet been made to the Ryanair plane.
Guzzetti said the latest accident could prompt the FAA and NTSB to examine whether that deadline should be moved up.
