A National Transportation Safety Board (NTSB) probe revealed that an engine fan blade broke off on a July 10 Ryanair flight, sending debris that shattered a passenger window and caused a 61-year-old man’s head to be partially sucked out of the fuselage over Greece.
The Incident and Flight Mechanics
The terrifying event unfolded shortly after a Boeing 737-800, operated by Ryanair subsidiary Malta Air, took off from Thessaloniki, Greece, on July 10, according to investigations detailed by the National Transportation Safety Board (NTSB). An engine fan blade fractured during the climb, propelling debris that punctured the aircraft’s fuselage in multiple locations and completely shattered a cabin window. The rapid decompression caused oxygen masks to deploy immediately from the cabin ceiling.
A 61-year-old passenger seated near the blown-out window suffered neck and shoulder injuries alongside friction burns when his head was pulled toward the breach. Fellow passengers pulled the man back inside to safety before the flight crew managed to stabilize the aircraft. Flight-tracking data from Flightradar24 indicates the narrow-body jet had climbed past 15,000 feet approximately six minutes after departure before executing an immediate descent to 6,000 feet. The aircraft burned fuel for 30 minutes before returning to Thessaloniki International Airport roughly an hour after takeoff.
The Bottom Line
- Regulatory Friction: The NTSB openly reprimanded Ryanair chief executive Michael O’Leary for public comments prematurely attributing the failure exclusively to foreign object damage before investigators finalized their conclusions.
- Engine Evidence: Investigators confirmed discovering bird remains inside the damaged right engine, suggesting the plane may have struck birds as it took off in Greece.
- Fleet Profile: The aircraft involved is a Boeing 737-800 delivered new to Ryanair (ISE: RYA) in 2008, seating up to 189 passengers and operated regionally by Malta Air.
Regulatory Pushback and Public Statements
International aviation protocols permitted Greece’s Hellenic Air and Rail Safety Investigation Authority to transfer lead investigative responsibilities to the U.S. NTSB. Tensions surfaced when NTSB officials publicly rebuked Ryanair CEO Michael O’Leary after he informed investors that the probe centered strictly on foreign object damage rather than aircraft age or airline maintenance records. The NTSB countered that investigators had not ruled out any contributing factors and asserted that O’Leary lacked authorization to discuss open findings.

Passenger accounts gathered by local media corroborated the sudden violence of the mechanical failure. One traveler described hearing a sound comparable to a bursting tire before recognizing an immediate loss of cabin pressure as the aircraft initiated its emergency descent. Following the safe landing, emergency responders met the flight on the tarmac, where one passenger sought and received medical treatment.
Operational and Fleet Metrics
The following operational details outline the aircraft and flight parameters associated with the July 10 incident:
| Metric | Detail |
|---|---|
| Airline Operator | Malta Air (Ryanair Subsidiary) |
| Aircraft Model | Boeing 737-800 (Capacity: 189) |
| Year Delivered | 2008 (Delivered New) |
| Departure Point | Thessaloniki, Greece |
| Maximum Altitude Reached | Over 15,000 feet (4,570 meters) |
Market Footprint and Outlook
As Europe’s largest budget carrier, Ryanair Holdings plc (ISE: RYA) faces heightened scrutiny regarding engine maintenance protocols and foreign object damage mitigation following the NTSB’s preliminary disclosures. While financial markets have largely absorbed the operational implications of the incident, ongoing oversight from international safety boards will dictate whether maintenance directives or engine inspection intervals face mandatory tightening across the broader narrow-body fleet.
