'Well forward' C.G. Implicated in TEB Challenger Overrun
"The center of gravity (c.g.) was found to be well forward of the allowable
limit," according to an NTSB update of the investigation into the Challenger
600 that overran Runway 6 on takeoff from Teterboro Airport, N.J., on
February 2. Initial findings of the investigation have indicated that the
airplane, as configured, 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
(the 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." The Safety Board also found that on the morning of
the accident, icing conditions at Teterboro were "minimal or nonexistent"
and there were "no anomalies" of the pitch-control system. A CVR transcript
will be released in the near future. Meanwhile, the FAA revoked the Part 135
certificate of Darby Aviation (dba AlphaJet), one of the operators connected
with the Challenger flight.
