The October 2002 NTSB hearing heard evidence from one American Airlines Captain John Lavelle, who had flown a number of times with F/O Stan Molin on the B727 in 1997-1998. He recalled that F/O Molin had aggressively used rudder in an oscillatory mode on a B727 to attempt to control roll. This action didn't level the wings, but it did create sideloads due to yaw. They discussed this during the flight. Captain Lavelle recalled that Molin had told him that he was following American Airlines training procedures. The NTSB concluded that the PF [F/O Sten Molin] tended to react to wake turbulence using excessive control inputs, and that his control inputs in this case were too aggressive and the degree of his initial rudder pedal activation was unnecessary to control the aircraft.
