Vietnam Airlines 787 Near-Disaster In Munich: Investigators Reveal A Bizarre Cause
Investigators said repeated brake inputs at the captain’s pedals slowed acceleration and left the 787-9 grounded after an emergency landing.
On September 28, the German Federal Bureau of Aircraft Accident Investigation released an interim report on the August 15 Vietnam Airlines Boeing 787-9 incident at Munich Airport, revealing repeated brake inputs during takeoff.
Flight recorder data showed brake system activation shortly after the takeoff roll began, with maximum commands reaching around 27% on the left and 17% on the right.
The aircraft attempted rotation at 163 knots, below the calculated 175 knots, while the tail and landing gear struck approach lights after overshooting the runway, leaving it "substantially damaged."
Before returning for an emergency landing in Munich, the crew dumped 62 metric tons of fuel to reduce weight, and no injuries were reported among the 287 people on board.
German investigators have not determined whether the brake inputs stemmed from pilot action or technical malfunction, as the cockpit voice recording was overwritten and examination of brake system control units remains ongoing.
A Vietnam-Airlines-machine shoots in Munich beyond the runway and can just take off. Now the competent experts give an insight into the investigations into the incident.
