1986 (?) B737 severe pitch-up over Los Angeles with two test pilots
Around 1986 there was a close shave over Los Angeles airport where two test pilots flying a Boeing 737 experienced a severe pitch up while approaching to land (?). The pitch up could not be stopped and was so severe that the only way the crew could reduce the effect of the pitch up was to quickly roll the aircraft steeply towards the nearest horizon. Once the nose was lowered by this method, the wings were levelled and the aircraft brought under control.
I believe the aircraft came perilously close to hitting buildings. This recovery from a nose high,wings level, unusual attitude is currently still incorporated in the Boeing 737 Flight Crew Training Manual, Chapter 7 Maneuvers - Upset Recovery.
Despite Googling for details of this incident, none have been successful. Would greatly appreciate if anyone can provide more factual details of this incident. The company I work for in Australia has long since programmed this incident in its Boeing 737 Classic full flight simulator and it is quite dramatic .
