What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The flight was conducted in accordance with 14 CFR part 91, the purpose appears to have been a personal trip to go fishing. The aircraft last departed lamar, CO, IFR to Rexburg, Idaho. Upon arrival in the vicinity of Rexburg, the pilot cancelled IFR, reported left downwind and left base for runway 17. At about this time an FBO manager reports observing the aircraft on what appeared to him about a 1 1/2 mile final, a little low and crabbing to the right. Then suddenly the aircraft appeared to pitch-up, the right wing dipped and the aircraft appeared to enter a spin and crashed. The FBO manager estimated the aircraft to be at 200 or 300 feet above ground when the stall spin occurred. A post accident weight and balance calculation indicated a CG of 89.94 and weight of 4,406 lbs. This puts the CG within the envelope. There was no reported icing. The aircraft arrived with possibly 9 to 10 gallons of gas. The FBO manager arrived within minutes of the accident and stated he did not smell any fuel in the area and did not observe any dripping from the wings, fittings or fuselage. There is a report that some first responders reported the smell of fuel in the area. The props indicated the engines were under power at impact.
