![]() ![]() The lack of proximal feedback on the flight guidance panel might have contributed to his failure to notice that the autopilot was not engaged. It is also possible that differences between the avionics panel layout on the accident airplane and the airplane he previously flew resulted in mode confusion and contributed to his failure to engage the autopilot. A belief that the autopilot was engaged may have contributed to his lack of attention. Inadequate flight instrument scanning during this time of elevated workload resulted in the pilot allowing the airplane to climb through the assigned altitude, to develop an overly steep bank angle, to continue through the assigned heading, and to ultimately enter a rapid descent without effective corrective action. The PFD annunciation was the only indication of autopilot engagement. This implied that the pilot failed to confirm autopilot engagement via an indication on the primary flight display (PFD). However, based on the flight profile, the autopilot was not engaged. It is likely that the pilot attempted to engage the autopilot after takeoff as he had been trained. The enhanced ground proximity warning system (EGPWS) provided both "bank angle" and "sink rate" alerts to the pilot, followed by seven "pull up" warnings.Ī postaccident examination of the recovered wreckage did not reveal any anomalies consistent with a preimpact failure or malfunction. During the subsequent descent, the airspeed and descent rate reached about 300 knots and 6,000 fpm, respectively. The bank angle ultimately decreased to about 25 degrees. ![]() The bank angle increased to about 62 degrees and the pitch attitude decreased to about 15 degrees nose down, as the airplane continued through the assigned heading. The flight director provided alerts before the airplane reached the assigned altitude and again after it had passed through it. The airplane climb rate exceeded 6,000 fpm during the initial climb and it subsequently continued through the assigned altitude of 2,000 ft mean sea level. Dark night visual conditions prevailed at the airport however, the airplane entered instrument conditions shortly after takeoff. The airplane entered a right turn shortly after takeoff and proceeded out over a large lake. ![]()
