... Teterboro Wreckage Tells a CG Story
After weighing aircraft wreckage and contents, the NTSB has determined the Challenger's center of gravity was well forward of the allowable limit. The NTSB took into account the interior cabin configuration combined with full or nearly full fuel tanks, a full or nearly full passenger load and minimal passenger baggage. The horizontal stabilizer was set to a normal position. However, after plugging all of the data into a simulator, the aircraft would not rotate at the defined rotation speeds. No problems were found with the pitch control system or autopilot, but both will be examined further. Assistance from the Flight Data Recorder (FDR) will likely be minimal. The FDR operated for only 10 seconds during the airplane's deceleration. The Cockpit Voice Recorder survived intact.
