Pilot in Command 52 Yrs Old, Stockbroker by Profession Commercial Pilot, SEL since Dec 1990 CFI since April 1992; 8 students in 2 yrs 1,484 hrs; No Instrument Time in last 6 months Active in Young Eagles and similar programs 2 trips from West Coast to Oshkosh Flying Habits as reported by other pilots
27
PIC Sleep and Activity History Prior to Starting the Flight In 3 days prior to last flight, slept an average of 6 hrs per night Visibly tired at last fuel stop prior to Cheyenne Start/End of 1 st Day’s trip over 10 hrs Insisted on 0615 takeoff for next morning due to approaching storm, but all 3 left Hotel at 0714 and took off at 0820
28
PIC Signs of Fatigue on 11 Apr Started aircraft with nose chock installed, shut down, had lineman remove chock, then restarted Prompted for ATIS Asked for “Special IFR” (meaning Special VFR due to field condition) Rolling Takeoff before Clearance Issued

Media Aspects
37
Summary The NTSB concluded that the probable cause “…was the pilot’s improper decision to take off into rapidly deteriorating weather conditions when the airplane was overweight and when the density altitude was higher than he was accustomed to, resulting in a stall caused by failure to maintain airspeed. Contributing to the PIC’s decision to takeoff was a desire to adhere to an overly ambitious itinerary, in part, because of media coverage.”

Results of a Study of 77 Cross-Country Accidents 31 were due to an Externally-Driven, Unplanned Event – Average Distance into Flight 78.1 nm – 23 due to Engine Failure – Avg Age 47 46 Controllable Exposure to Risk (Over twice the number of fatalities) – Average Distance into Flight 72.9 nm – 28 Weather-Related with Avg Dist 92.5 nm – 14 Loss of Control and Collision with Avg Dist 49.7nm – Avg Age 37.8
