Scheduled 14 CFR operation of BUSINESS EXPRESS, INC.
Incident occurred Tuesday, February 20, 1996 in RIFLE, CO
Probable Cause Approval Date: 07/17/1996
Aircraft: British Aerospace AVRO 146-RJ70A, registration: N832BE

NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

The first officer, who flew the LOC/DME-A approach to runway 26 at a Vref speed of 115+5 knots, said the airplane touched down 2500 feet past the threshold and went off the end of the 7000 foot runway, coming to a halt 300 feet beyond. The airport manager said, and FDR and GPS confirmed, the airplane touched down 4600 feet beyond the runway threshold at 138 knots ground speed and 119 knots indicated airspeed, and traveled 3400 feet before coming to a halt. Prior to landing, the crew did not request, nor did the airport or company dispatch give, runway condition, braking action, or precipitation reports. The captain said he found one inch of slush on the runway. The Airplane Flight Manual states landings 'on a slippery surface having a braking coefficient of friction of 0.05...are not permitted on a downhill runway unless the downhill slope is less than 0.5% and there is no tailwind component.' Runway 26 has a 1.2% downhill gradient and FDR data indicates the wind was 098 at 6 knots.

The National Transportation Safety Board determines the probable cause(s) of this incident to be:

The copilot's failure to compensate for wind conditions, resulting in excessive airspeed, and his failure to attain the proper runway touch down point. Factors were inadequate dispatch procedures and the captain's improper inflight planning/decision in that runway conditions were not requested or obtained; a tail wind, a wet downhill runway, hydroplaning conditions, and the captain's failure to adequately supervise the copilot.
