N49BX

On July 30, 2025, at 1046 eastern daylight time, a Lancair IVP airplane, N49BX, was destroyed when it was involved in an accident near Greenwood, Indiana. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

ADS-B data was not available from the FAA as FAA ADS-B data relies on data received by official FAA receivers, and no data was found for the accident flight. However, preliminary ADS-B data from a commercial service that utilizes private receiver data was obtained which depicted the accident flight.

The airplane was also equipped with a Garmin G900X avionics suite which had data recording capability that captured the accident flight. The data recorded by the Garmin system ended about 13 seconds before the ADS-B data. The Garmin and ADS-B data showed that the airplane departed from runway 19 at the Indy South Greenwood Airport (HFY), Greenwood, Indiana, at 1045. After takeoff, the airplane began a climbing left turn. The turn continued for about 30 seconds when the turn radius decreased while continuing to the left. The data then showed a rapid descent to the right. The total duration of the flight from the beginning of the takeoff roll was about 1 minute 30 seconds.

The Garmin avionics also recorded engine parameters. The final portion of the data showed that the engine was at 38 inches of manifold pressure, 2,650 rpm, and a fuel flow of about 44.5 gallons per hour. All engine readings were steady from power application during the takeoff until the end of the recorded data.
