BFU Releases First Findings on Vietnam Airlines Munich Incident

Germany’s Federal Bureau of Aircraft Accident Investigation has issued its first public summary of the Vietnam Airlines Boeing 787 incident at Munich, confirming key details of the dramatic takeoff, tail strike and damaged landing-gear discovered after the aircraft returned to the airport.

Runway Event Involved Near-Heavyweight 787 Departure

According to publicly available information from German and Vietnamese aviation authorities, the event occurred on 15 August, when a Vietnam Airlines Boeing 787-9 operating as flight VN34 attempted takeoff from Munich’s runway 26L bound for Hanoi. The widebody twinjet, registered VN-A867, was departing with a high takeoff weight approaching its certified limit, carrying more than 270 passengers and a large crew complement for the long-haul sector.

Data shared in official summaries and technical coverage indicates that the departure roll initially followed expected performance, matching previous flights from the same runway. The aircraft accelerated normally through the early part of the takeoff run, with engines set to takeoff thrust and no immediate signs of abnormal behavior.

Investigative material compiled so far points to a critical section of the roll roughly halfway along the 4,000 meter runway. At that point, flight crew reports and performance reconstructions describe an unexpected stagnation in acceleration, followed by a short period in which indicated airspeed did not increase as anticipated. The moment forced a rapid assessment in the cockpit about whether there was enough remaining distance to safely reject the takeoff.

By the time the second slowdown was perceived, the aircraft was close to or beyond decision speed, making a high-speed abort on the wet-concrete runway an increasingly risky option. The crew committed to continuing the takeoff, using available thrust and nose-up input to get the aircraft airborne before the runway end.

BFU Notes Tail Strike and Damage Consistent With Marginal Liftoff

The BFU’s initial account confirms that the 787 experienced a tail strike during rotation, with the aft fuselage contacting the runway surface. Imagery and damage assessments published by specialist accident databases and aviation media show significant abrasion and structural deformation at the rear lower fuselage, consistent with a high pitch angle at liftoff.

In addition to the fuselage contact, the incident left clear signatures along the runway and beyond. Investigators have documented extended tire marks on 26L and damage to approach lighting infrastructure near the runway end, suggesting that the aircraft’s main landing gear either locked or partially lost rolling efficiency at a critical point in the takeoff. Several tires were later found to be destroyed, shredded, or deformed far beyond typical rejected-takeoff scenarios.

After becoming airborne, the crew elected to level off, hold in the vicinity of Munich and return for an overweight landing. Photographs taken after the aircraft stopped on the runway show multiple destroyed main-gear wheels and scorched rubber fragments, illustrating the intense stress placed on the landing gear during both the takeoff run and the subsequent landing.

Despite the extensive structural and landing-gear damage, available reports indicate that there were no serious injuries among passengers or crew. Emergency services met the aircraft on the runway and the jet was later towed away for detailed inspection and repair assessment.

Early Focus on Braking and Thrust Anomalies

The BFU’s confirmation of key parameters has sharpened attention on several potential technical and operational factors. Performance analyses based on flight-tracking data and runway markings suggest that thrust output remained broadly normal during the departure. That pattern has led many specialists following the case to examine possible sources of drag or braking that could explain the sudden loss of acceleration.

Observers have pointed in particular to scenarios such as inadvertent wheel braking, a malfunction in the brake control system, or a related landing-gear issue that reduced the aircraft’s ability to accelerate despite commanded takeoff thrust. Some technical commentary has also noted the role that wet runway conditions, gear loading and anti-skid behavior might play when a high-mass aircraft accelerates near its performance margins.

Vietnamese civil aviation summaries referenced by international coverage state that crew members perceived a short period during which speed failed to increase, followed later by another drop in indicated speed near decision point. Because the event occurred so close to V1 and with limited remaining runway, the crew opted to continue the takeoff while managing an evolving abnormal situation.

Investigators are now working to correlate those cockpit observations with digital flight data. The 787’s onboard recorders, brake-pressure histories, engine parameters and weight-and-balance data are expected to provide clearer insight into whether the anomaly was due to a technical fault, an uncommanded braking input, or a combination of system behavior and human factors.

International Investigation Structure and Next Steps

Under international rules, Germany leads the investigation because the incident occurred at Munich and the engines were manufactured there, while Vietnam participates as the state of the operator and registry. Publicly available information shows that German, Vietnamese and manufacturer representatives are all involved in the work, mirroring the cooperative approach typical in long-haul jet investigations.

The BFU’s early communication outlines a familiar path: securing and analyzing flight recorders, mapping runway evidence, and conducting detailed inspections of the landing gear, brake assemblies, wheels and fuselage structure. Investigators are also gathering maintenance and dispatch records for VN-A867, including recent work on braking, anti-skid and thrust-control systems.

In parallel, the team is reviewing air traffic control recordings, airport surveillance footage and ground handling reports from Munich. That material can help verify aircraft positioning on the runway, clarify any last-minute changes to departure configuration and corroborate the timing of the abnormal acceleration events described in preliminary accounts.

The BFU typically publishes a more comprehensive preliminary report within several weeks of a serious incident, followed by an in-depth final report that can take a year or longer. For now, the bureau’s initial confirmation of core facts in the Vietnam Airlines case offers a clearer baseline, while leaving open the central question of what triggered the loss of acceleration that set the chain of events in motion.
