JTSB inquiry after JAL 777 tail strike

On March 31, 2012, a Japan Airlines 777 landed at Tokyo Haneda. The captain believed that the aircraft had bounced and was floating after the
touchdown, and ordered a go around, despite the first officer activating reverse thrust. The first officer apparently had control of the aircraft at
the time. The captain ordered the go around, took over, cancelled the reverse thrust and pushed the power up.

The aircraft at that point had been down for 10 seconds and was down to 180 knots. During the time it took the engines to spool up, the nose rose
dramatically, and six seconds later a tail strike warning was initiated. There was substantial damage to the lower aft fuselage as a result.

Japanese investigators believe that a Boeing 777-200 struck its tail after the captain ordered a go-around despite the first officer’s having
already initiated reverse thrust.

The captain of the Japan Airlines aircraft believed the aircraft had bounced and was floating after the touchdown at Tokyo Haneda on 31 March 2012.

Japan Transport Safety Board indicates that this perception arose from fluctuations in vertical acceleration as the 777 settled, having landed
initially on its right main gear.

While the first officer, who was flying, had activated the speedbrakes and raised the reverse-thrust levers after touchdown, the inquiry says this was
probably unnoticed by the captain because he was looking out of the cockpit window to confirm the aircraft’s attitude.
