NTSB preliminary report:

NTSB Identification: CEN14FA099
14 CFR Part 91: General Aviation
Accident occurred Sunday, January 05, 2014 in Aspen, CO
Aircraft: CANADAIR LTD CL 600 2B16, registration: N115WF
Injuries: 1 Fatal,2 Serious.
This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On January 5, 2014, at 1222 mountain standard time, a Bombardier CL-600-2B16, N115WF, impacted the runway while attempting to land on Runway 15 at Aspen-Pitkin County Airport/Sardy Field (KASE), Aspen, Colorado. There were two crewmembers and a passenger onboard. One crewmember was fatally injured; the other crewmember and passenger received serious injuries. The airplane was destroyed. The airplane was registered to the Bank of Utah Trustee and operated by Vineland Corporation Company, Panama, South America under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed for the flight, which operated on an instrument flight rules flight plan. The flight originated from Tucson International Airport (KTUS), Tucson, Arizona, at 1004.

According to preliminary information from the Federal Aviation Administration, the flight was in radio contact with ASE air traffic control (ATC). At 1210, N115WF utilized the localizer DME-E approach into KASE. ASE ATC reported winds as 290º at 19 knots, with winds gusting to 25 knots to the crew before landing. The crew executed a missed approach, and then requested to be vectored for a second attempt. On the second landing attempt N115WF briefly touched down on the runway, then bounced into the air and descended rapidly impacting with the ground at midfield. No further communications were received by ASE ATC from the accident airplane.

At 1220, the KASE automated surface observation system (ASOS) reported the following weather conditions: wind from 320° true at 14 knots gusting to 25 knots, wind variable from 280° to 360, visibility 10 miles in haze, scattered clouds at 4,700 feet above ground level, ceiling broken at 6,000 feet, temperature -12° Celsius (C), dew point temperature -21° C, altimeter 30.07 inches of mercury. The remarks indicated a peak wind from 320° at 26 knots occurred at 1204.

The KASE ASOS one-minute data at the time of the accident reported the wind at 333º true at 14 knots gusting to 17 knots.

The cockpit voice recorder, flight data recorder, and Enhanced Ground Proximity System were recovered.Index for Jan2014 | Index of months
Bouncing back into the air at midfield seems an awful lot like a few long landings I've witnessed where the airplane was forced onto the runway at excessive speed and landed on the nose wheels first. I saw a Challenger do that once before, but it went around before the nose wheels contacted the runway again. Even at normal touchdown speed it doesn't usually appear that the nose wheels are very far off the runway surface when the mains touch down. Probably not allot of margin for error it looks like to me. Someday when the FDR traces are available for viewing, it will be interesting to see what the indicated airspeed was during the sequence and compare it to the ref speed.

Can any Challenger drivers confirm whether Vref is higher for a given weight at 8,000 PA than it is at SL on the 601? It's not on the types I've flown but I seem to remember hearing something about that once...
