Last Update: November 29, 2023 / 12:08:26 GMT/Zulu time
Netherland's Onderzoeksraad (DSB) have opened an investigation into the occurrence.
The Aviation Herald received information that there has been damage to the aircraft, not visible from the outside of the aircraft.
On Nov 29th 2023 the Onderzoeksraad reported that the investigation was aborted after establishing the facts. The DSB summarized the sequence of events:
During the takeoff roll, the flight crew received a ‘Bleed Air Leak’ message on the Engine Indicating and Crew Alerting System (EICAS), followed by ‘Bleed Air Failure’ message, shortly after. At that moment, they also received a call through the intercom from one of the cabin crew members and were informed of the presence of dust and debris in the passenger cabin.
The pilots decided to abort the takeoff at approximately 90 knots indicated airspeed. Several passenger heard a loud bang, just before the aircraft aborted its takeoff. They subsequently noticed dust and debris in the passenger cabin compartment as well as hot air near the ventilation outlets at floor level.
Investigation revealed that a titanium pneumatic duct, located in the left sidewall near the aft cargo compartment, had ruptured. The material insulating the duct was also damaged, which resulted in dust and debris from ducting insulation entering the passenger compartment through the ventilation outlets near the passenger floor.
According to Boeing, the duct is wrapped with a high temperature air duct insulation blanket. In addition to the insulation around the duct, there were insulation blankets along the interior of the fuselage adjacent to the duct rupture. All insulation material used in the area of the rupture is fiberglass-based insulation material.
