Olathe-Johnson County (New Century)

The airplane had recently undergone an annual inspection, and the pilot planned to fly the airplane back to his home base. After receiving clearance from air traffic control, the pilot proceeded to take off. The airplane accelerated and reached a peak groundspeed of 81 kts about 2,075 ft down the 4,097-ft runway. Once airborne, the airplane drifted slightly to the right and the pilot radioed an urgent need to return to the airport. The controller cleared the airplane to land and no further transmissions were received from the accident airplane. The airplane’s flight path showed that it slowed before turning back toward the left and the airplane’s speed continued to decrease throughout the remainder of the data. The final data point recorded the airplane at a groundspeed of 45 kts. The groundspeed would equate to 60 kts airspeed when considering the 15-kt headwind. The stall speed chart for the airplane listed the minimum stall speed for any configuration as 64 kts. Postaccident examinations of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. External and internal engine damage indicated that the engine was producing power at the time of impact, but the amount of power output could not be determined. Based on the available information, the pilot perceived an urgent need to return the airplane to the airport; however, due to the amount of damage from the impact and postimpact fire, the reason that the pilot was returning to the airport could not be determined. Stall speed information for the airplane, the recorded winds, and flight track data, indicated that the airplane encountered an aerodynamic stall before impacting the ground near the departure end of the runway. Since the airplane stalled and impacted the ground before reaching the perimeter of the airport, the pilot may not have had sufficient altitude to execute a forced landing to the empty field off the departure end of the runway.

The noninstrument-rated private pilot was conducting a visual flight rules (VFR) cross-country flight while receiving VFR flight following services from air traffic control. Radar data and voice
communication information indicated that the airplane was in cruise flight as the pilot deviated around convective weather near his destination. The controller issued a weather advisory to the pilot concerning areas of moderate to extreme precipitation along his route; the pilot responded that he saw the weather on the airplane's NEXRAD weather display system and planned to deviate around it before resuming course. About 3 minutes later, the pilot stated that he was around the weather and requested to start his descent direct toward his destination. The controller advised the pilot to descend at his discretion. Radar showed the airplane in a descending right turn before radar contact was lost at 2,900 ft mean sea level. There were no eyewitnesses, and search personnel reported rain and thunderstorms in the area about the time of the accident. The distribution of the wreckage was consistent with an in-flight breakup. Examination of the airframe revealed overload failures of the empennage and wings. No pre-impact airframe structural anomalies were found, and the propeller showed evidence of rotation at the time of impact. Further, there was no evidence of pilot impairment or incapacitation. Review of weather information indicated that the pilot most likely encountered instrument meteorological conditions as the airplane descended during the last several minutes of flight. During this time, it is likely that the pilot became disoriented while attempting to maneuver in convective, restricted visibility conditions, and lost control of the airplane. The transition from visual to instrument flight conditions would have been conducive to the development of spatial disorientation; the turning descent before the loss of radar contact and the in-flight breakup are also consistent with a loss of control due to spatial disorientation.

According to the flight instructor, he and the pilot rated student receiving instruction were operating under instrument flight rules in instrument meteorological conditions. He reported that throughout the flight the airplane accumulated light rime ice. He recalled that after holding at a Very High Frequency Omni-Directional Range (VOR), they completed a VOR approach, executed the missed approach procedure, set the power to climb at the airspeed of 130 knots indicated airspeed and began to climb to 5000 feet. He reported that as they climbed they encountered freezing rain, the airspeed began to deteriorate and the degree of ice accumulation increased from light to moderate. He reported that all of the airplane's de-ice systems were functioning yet he was not able to maintain altitude. He determined that landing at the destination airport was not an option and executed a forced landing in an open field. He affirmed that during the landing the airplane bounced several times before coming to a stop. The airplane sustained substantial damage to the firewall, forward pressure bulkhead and puncture holes in the airplane skin. The pilot reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal flight operation.

The pilot and his wife were en route from Palm Springs, CA, to Olathe, KS, and had stopped for fuel at Farmington, NM. After departure, the aircraft was eventually cleared to FL210. At 1934 the pilot gave Denver ARTCC the following pirep: 'there's been some snow but I've been mostly in and out of the tops. Looks like I got clear skies above me most of the time...and it is moderately rough from time to time.' At 2045 Kansas City ARTCC advised the pilot he was at FL213. The pilot acknowledged he had drifted off altitude and was correcting and was heading 060°. At 2047 the controller advised the pilot he was at FL203. The pilot replied, 'we've had a gyro failure.' At 2049 radar contact was lost. The aircraft impacted an open field in a near vertical attitude. There was no evidence of airframe, engine, propeller, or flight control failure. Only one vacuum pump was recovered. The instrument panel and autopilot system were destroyed. Both occupants were killed.

The pilot departed Iola Airport in poor weather conditions on a cargo flight to Olathe-Johnson County Airport. En route, communication systems (transmitter/receiver) failed and on approach, the pilot lost control of the airplane that stalled and crashed in a field. The aircraft was destroyed and the pilot, sole on board, was killed.
