Boeing B747 Loss Of Control During Landing

The initial cause of the accident was the incomplete reduction of thrust on the left outer engine at the beginning of deceleration. This caused the de-activation of the automatic braking systems and the non-extension of the n° 1 thrust reverser. The inadvertent selection of full thrust on this engine after the landing created high thrust…… Continue Reading →

Boeing B747 Stick Shakers Activation On Takeoff

On takeoff both stick shakers began to operate continuously shortly before V1. The Captain elected to continue the takeoff and, after a period of troubleshooting in the air, dumped fuel and returned to land. Maintenance engineers consulted the aircraft BITE (Built-In Test Equipment) and replaced the right-hand ADC (Air Data Computer). The subsequent takeoff proceeded…… Continue Reading →

Boeing B767 Dual Engine Failure

The B767 climbed to its cruising altitude of 41,000 feet and the first hour of flight was straightforward for the experienced flight crew. The two pilots were shocked to see cockpit instruments warning of low fuel pressure in the left fuel pump. At first they thought it was a fuel pump failure. Seconds later, warning…… Continue Reading →

Boeing B737 Hard Landing

The aircraft was not decelerated enough when nearing the runway end so the pilot flying attempted to turn the aircraft onto taxiway November…… Continue Reading →

Boeing B777 Descent Below MSA and Near CFIT

On 24 July 2011, a Boeing 777-300 on a scheduled passenger flight from Bangkok (Thailand) to Melbourne (Australia) descended so far below the vertical profile for the night non precision approach procedure being flown in VMC at destination that ATC, observing that the aircraft was below the minimum safe altitude for the range from touchdown,…… Continue Reading →

Boeing B777 Runway Excursion on Landing

A Boeing 777-200 aircraft was landing in rain at the Singapore Changi airport, when its left hand landing gear momentarily departed the paved surface of Runway 02L and went onto the soft grass verge before returning to the paved runway surface. Subsequently, the aircraft taxied on its own to the designated passenger gate. All occupants…… Continue Reading →
