Boeing 747 F-GITA operated Flight AF072, Paris-Los Angeles-Tahiti. Weather was good when the flight approached Tahiti at night. The aircraft positioned for a Runway 22 VOR-DME approach. At 21:05 the aircraft touched down at a speed of 168 knots. Two seconds later no. 1 engine power increased to 107% N1.
Because of this the spoilers did not deploy and the automatic brake disarmed. Reverse thrust was used on all remaining engines. Because of difficulties due to thrust asymmetry, the no. 4 engine thrust reverser was cancelled. The aircraft overran the runway and ended up in a lagoon.
There was an issue with the ATH, at 500ft radioalt. all 4 engines passed from 68% to 96% N1. The speed was too high and the crew should have selected a TOGA. Instead the PF tried to set the TL to idle without announing it. While doing so he couldn't disconnect the ATH.

The report stated that the crew was probably too busy evaluating the aircraft trajectory and during that time never looked at the instruments.
in particular the PF was found to be anxious to activate the reverse thrust as soon as possible that his hand was probably not on the TL when engine 1 increased power to 107% N1.
