Broken engine fragments smashed a cabin window of a Ryanair plane causing a man's head and right shoulder to be sucked into the hole last month, US investigators have said.
The National Transportation Safety Board (NTSB) wrote in a preliminary report that this happened after an engine fan blade broke shortly after takeoff on the 10 July flight from Greece to Germany.
Serbian national Ljubisa Karović's head and right shoulder were sucked out of the plane's window, leaving him "seriously injured and in shock".
His wife Svetlana Grković Maksimović later told BBC Serbia that she and two other passengers held onto his legs for several minutes.
The NTSB said the flight from Thessaloniki to Memmingen "experienced a No. 2 (right) engine fan-blade-out (FBO) failure during climb out".
"The crew elected to return to SKG [Thessaloniki International Airport] where they made an uneventful landing."
The NTSB was "delegated the investigation in full" by the Greek authorities in the days following the incident.
It also detailed a timeline of events given by the flight crew, who said they received a "high vibration" engine alert during the climb.
In response, they reduced the engine power and carried out a series of checks. When the vibrations stopped, the crew continued to climb on autopilot, the report said.
But the engine vibrations then increased and the crew heard a loud bang, prompting them to declare an emergency and begin their descent.
Flight attendants reported hearing and feeling the vibrations, and seeing a small amount of smoke before the oxygen masks were deployed.
One flight attendant said they then noticed passengers calling for help after a passenger became "partially lodged in a damaged cabin window", with the entire window missing.
The engine had undergone ultrasonic inspections in May this year with no findings of fault, the report stated.
Ryanair boss Michael O'Leary earlier suggested that the incident may have been caused by "foreign object damage" to an engine.
The aircraft was operated by Ryanair's subsidiary Malta Air.

"A confirmed uncontained fan-blade failure after recent clean inspections signals elevated maintenance and possible regulatory risk for Ryanair’s 737 fleet that the market is currently under-pricing."
The NTSB preliminary report pins the 10 July Ryanair incident on an uncontained engine fan-blade-out (FBO) failure despite a clean ultrasonic inspection in May, directly contradicting Michael O’Leary’s initial “foreign object damage” narrative. For RYAAY (and its Malta Air subsidiary) this is the second high-profile engine event in recent memory; while the aircraft landed safely, the cabin decompression, passenger injury, and potential grounding of similar CFM56-powered 737s raise near-term maintenance and regulatory cost risks. The market has so far treated this as isolated, but any pattern of blade fatigue could force fleet-wide inspections and hit margins in an already high-cost environment.
Engine FBO events are statistically rare; Ryanair’s overall safety record remains strong, the aircraft returned uneventfully, and European regulators have not issued emergency airworthiness directives. Shares could easily shrug this off as a one-off with no lasting earnings impact.
"The failure of a blade that passed ultrasonic inspection just two months prior indicates a potential breakdown in maintenance oversight that could trigger costly, fleet-wide regulatory interventions."
The NTSB report on the Malta Air incident is a significant tail risk for Ryanair (RYAAY). While management initially deflected toward 'foreign object damage,' the confirmation of a fan-blade-out (FBO) failure despite May ultrasonic inspections suggests a potential systemic failure in maintenance protocols or engine life-cycle management. If the investigation reveals that the ultrasonic inspection process was flawed or that the engine manufacturer (likely CFM) has a latent defect in these blades, Ryanair faces not just reputational damage, but massive grounding costs and fleet-wide inspection mandates. Investors should watch for the FAA or EASA to issue an Airworthiness Directive (AD) for this engine type, which would severely impact operational margins and capacity guidance for the upcoming quarters.
The incident could be a statistically isolated manufacturing defect rather than a maintenance failure, meaning the financial impact will be limited to a one-off insurance settlement rather than a systemic fleet grounding.
"The mechanical failure itself is manageable; the reputational and regulatory aftermath depends entirely on whether this is isolated or signals a fleet-wide inspection gap."
This is a contained mechanical failure, not a systemic safety crisis. Fan-blade-out events happen in commercial aviation—they're engineered-for scenarios. The real story: the aircraft performed as designed. Engine failed, crew managed descent safely, passengers survived an extreme event. The window breach is the anomaly, not the engine failure itself. Ryanair's maintenance (ultrasonic inspection in May) followed protocol. However, the gap between 'no findings' in May and July failure warrants scrutiny—either inspection methodology, blade material fatigue, or foreign object damage timing matters for liability and fleet confidence.
If this blade failure mode is recurring across CFM56 or similar engines on aging narrow-bodies, a single incident becomes a pattern. Ryanair's cost-cutting reputation could amplify regulatory pressure even if the airline followed rules—perception risk to bookings and insurance premiums is real regardless of technical culpability.
"The potential for incremental maintenance costs and stricter inspections could dent Ryanair's near-term margins if a broader root-cause investigation unfolds."
A single blade-out event on a Ryanair (RYAAY) Malta Air Boeing 737-800 flight highlights safety risk but is not evidence of a systemic engine defect. The NTSB notes no fault found in ultrasonic May checks; authorities are exploring foreign object damage as a cause. The risk to investors is twofold: near-term cost from inspections and maintenance if regulators require broader checks, and potential sentiment risk if a series of similar events surfaces. However, the incident is unlikely to trigger a fleet-wide grounding unless a pattern emerges. The missing context: engine model specifics, parts supply, and whether any regulator actions follow.
The strongest counter is that this reads like a single-outlier incident with no proven defect; regulators typically treat this as a rare event unless multiple events occur, so the market may overreact to headlines rather than data.
"Crew retention risk from the incident could raise Ryanair’s labor costs more than direct maintenance or grounding expenses."
Claude correctly flags perception risk from Ryanair’s cost-cutting brand, but nobody has noted second-order crew and pilot retention pressure. A decompression event plus O’Leary’s initial deflection could accelerate fatigue-related attrition at a carrier already facing European pilot shortages, lifting unit labor costs faster than any AD-driven maintenance hit.
"The primary financial threat is not labor attrition but the operational margin compression from potential AOG mandates and the reputational cost of misleading public statements."
Grok, your focus on labor is misplaced. The real risk isn't pilot attrition; it's the liability shift. If O'Leary's 'foreign object' narrative is proven false, the legal discovery process could expose internal maintenance culture, not just technical failures. This creates a 'reputational tax' on the stock. If EASA mandates inspections, the cost isn't just the labor; it's the AOG (Aircraft on Ground) time during peak travel, which is far more damaging to margins than pilot retention issues.
"Reputational liability exposure matters more than AOG timing; the real tail risk is regulatory restrictions on fleet utilization, not margin compression from scheduled maintenance."
Gemini conflates two separate risks. An AD-driven inspection mandate is a cost; AOG time during peak travel is an operational constraint. But Ryanair's margin compression from AOG depends entirely on load factors and pricing power—neither guaranteed to collapse. More pressing: if discovery reveals maintenance shortcuts (not just the blade failure), that's a regulatory capital-allocation problem, not a margin problem. EASA could impose operational restrictions beyond inspections.
"AD- or OEM-driven inspections could dominate Ryanair's near-term margin risk, especially during peak season."
Gemini's focus on liability shift undervalues the near-term margin risk from regulatory-driven inspections and AOG time. If an engine blade issue prompts an AD or OEM-backed inspection campaign, Ryanair faces costly downtime and spare-parts bottlenecks during peak season, likely eclipsing any labor-cost concerns. Even without an AD, airlines may preemptively stock spares and accelerate MRO with higher day-rate charges, embedding a material margin risk that could persist beyond the initial headlines.
