Forward C.G. implicated in TEB Challenger

“The center of gravity was found to be well forward of the allowable limit,” according to an NTSB update on the accident in which a Challenger 600 overran a runway on takeoff from Teterboro Airport, N.J., on February 2 (see page 58). Initial findings of the investigation have indicated that, as configured, the airplane would have had a c.g. “well forward of the forward limit based on its cabin interior configuration combined with full or nearly full fuel tanks, including the fuselage tank, and a full or nearly full passenger load and minimum passenger baggage,” the NTSB said. In addition, the horizontal-stabilizer trim position was in the middle of the green band (normal takeoff range). The NTSB said it conducted tests using a simulator to evaluate the airplane’s takeoff characteristics based on the trim settings and weight-and-balance data. “The initial findings of those simulations indicate the airplane would not rotate for takeoff at the defined rotation speed.”
