Report details Vietnam Airlines 787’s troubled Munich take-off

A recently submitted report has provided the clearest picture yet of how a Vietnam Airlines Boeing 787 departing Munich came close to overrunning the runway, suffering a tailstrike and tire failures before making an emergency return to the airport.

Late rotation and fluctuating speed on runway 26L

According to publicly available information from Vietnam’s Civil Aviation Authority and translated local media coverage, the incident involved Vietnam Airlines flight VN34 from Munich to Hanoi on August 15. The flight was operated by a Boeing 787-9, registration VN-A867, departing from runway 26L at Munich Airport.

Reports indicate that during the take-off roll, roughly halfway along the runway, the flight crew noticed the aircraft’s speed stagnate for about two seconds instead of continuing its normal acceleration. After that brief plateau, the speed increased toward the decision speed but then reportedly began to decrease again, creating a rapidly narrowing margin for either a rejected take-off or a safe lift-off.

With limited distance remaining, the crew assessed that there was not enough runway length left to safely abort the take-off. They reportedly advanced the engines to maximum thrust and continued the roll. As the end of the paved surface approached, with only several dozen meters remaining, the pilots initiated rotation, raising the nose to get the 787 airborne.

The aircraft became airborne but at the cost of contact with the runway and overrun markings at the far end. Video recordings shared on social media and aviation forums show dust and debris being kicked up behind the aircraft as it lifts off, consistent with the jet using almost every available meter of pavement.

Tailstrike warnings and blown tires prompt emergency return

Shortly after liftoff, cockpit systems began to register abnormal indications. Publicly available summaries of the crew’s report state that the pilots received warnings associated with a possible tailstrike, along with alerts that four of the eight main landing gear tires had lost pressure. The combination pointed to significant contact between the aircraft and the runway during the last seconds of the take-off roll.

With these indications and potential structural or landing gear damage, the flight crew decided not to continue toward Hanoi. Instead, they informed air traffic services of the situation and set up for an immediate return to Munich to have the aircraft inspected on the ground.

Because the aircraft had departed on a long-haul international sector, it was still heavy with fuel. To reduce landing weight and lower the stress on the airframe and landing gear, the crew began fuel jettison procedures while circling in the vicinity of the airport. Flight-tracking data shared by enthusiasts shows the 787 holding in extended patterns over southern Germany for more than an hour as it burned and dumped fuel.

As part of the return, the crew flew several low passes to allow ground observers and airport services to visually assess the condition of the landing gear. Public reports suggest that these external checks did not reveal obvious fire or uncontrolled structural failure, and the crew proceeded with an approach to runway 26R, the airport’s other main runway.

Heavy landing scatters debris and disrupts operations

The 787 touched down on runway 26R at Munich at approximately 15:57 local time, about two hours after the initial departure. Even with the reduced fuel load, the landing weight remained high for the aircraft, and the condition of the main gear was uncertain.

Photos and video published online after the event show extensive damage to the tires on the left main landing gear, with shredded rubber and fragments of wheel assemblies visible on the runway and adjacent taxiway. Aviation community reports describe large amounts of debris scattered along the landing roll, requiring a full closure of that runway while inspection and cleanup took place.

Despite the severe damage to the landing gear tires, the aircraft came to a controlled stop on taxiway A4. Emergency vehicles surrounded the aircraft, but there were no reports of fire. Passengers and crew disembarked via mobile stairs and were transported to the terminal. No injuries have been reported among the 250 people on board, according to media summaries.

The disruption to airport operations was significant. With emergency services concentrated on the incident aircraft, one runway remained closed to traffic until inspections were completed and the debris removed. Flight tracking data and eyewitness accounts indicate that departures and arrivals were temporarily suspended, with residual delays persisting after operations resumed.

Preliminary findings focus on performance margins

While only an initial report has been submitted, early information points to a critical chain of performance and decision-making factors. Aviation specialists commenting publicly note that a long, late rotation near the end of the runway is often associated with tight take-off performance margins, either because of aircraft weight, environmental conditions or miscalculated settings.

Observers have highlighted that Munich’s runway 26L offers substantial length for widebody operations, which makes the near-overrun particularly notable. Video footage shared by passengers and ground spotters shows the 787 still on the ground at an unusually late point, before finally rotating in a plume of dust and debris just beyond the runway end.

At this stage, no official explanation has been released regarding the momentary stagnation and subsequent fluctuations in airspeed during the take-off roll. Potential contributing factors under discussion within the aviation community include thrust setting issues, incorrect performance calculations, or unexpected resistance such as braking or system anomalies. Investigators are expected to examine recorded flight data in detail to clarify the sequence.

Vietnam’s civil aviation regulator has outlined, in general terms, that the aircraft sustained a tailstrike and multiple tire failures, as well as scraping damage along the rear underside of the fuselage. The 787 remains grounded in Munich while engineers and investigators document the structural condition of the airframe.

Next steps for investigators and the airline

The full technical investigation is being coordinated between Vietnamese and German aviation authorities, with support from the aircraft manufacturer and engine suppliers. A preliminary factual report is typically issued within weeks, while a comprehensive final report detailing causes and safety recommendations can take many months.

Investigators are expected to focus on several key areas, including take-off performance calculations, crew decision-making at high speed, aircraft configuration, and the functioning of systems that monitor speed, thrust and braking. Detailed examination of the damaged landing gear and fuselage structure will help determine how close the aircraft came to suffering more serious failures during both the take-off and the overweight landing.

For Vietnam Airlines, the incident comes at a time when long-haul operations are central to its network strategy. The 787-9 fleet is a cornerstone of its services to Europe and other intercontinental destinations, and the loss of a single airframe to long-term repairs or potential write-off could have noticeable commercial implications.

The event in Munich is likely to draw close attention throughout the industry as a high-profile case study in take-off risk management. As more details emerge from the investigation, regulators and airlines may review procedures for high-speed take-off decision points, fuel management and overweight returns, with the aim of ensuring that future flights faced with similar scenarios have wider safety margins than the one that left Munich’s runway with meters to spare.
