The occurrence

The Beechcraft V35B Bonanza (registration N6658R, serial number D-103232) was in a shallow climb, heading southbound, in the vicinity of Warrenton, Virginia. The aircraft was operated under visual flight rules for the purposes of a biennial flight review. The Piper PA-28-140 (registration N23SC, serial number 28-21217) was in level flight, also under visual flight rules, and was heading in a southeasterly direction. At 1604:45 Eastern Daylight Time, the aircraft collided approximately 1800 feet above sea level. The Beechcraft broke up in flight, and the pilot and flight instructor were fatally injured. There was a post-impact fire at the Beechcraft accident site. The pilot of the Piper, who was the sole occupant of the aircraft, conducted a forced landing in a pasture, approximately 6 nautical miles south of the Warrenton-Fauquier Airport. The pilot sustained injuries, which required examination at a local hospital.

The Piper was registered to a Federal Aviation Administration (FAA) employee, and the Beechcraft was registered to a National Transportation Safety Board (NTSB) employee. Given the unique circumstances surrounding the ownership and operation of the accident aircraft, the United States, as the State of Occurrence, represented by the NTSB, and Canada, represented by the Transportation Safety Board (TSB), respectively requested and accepted delegation of the accident investigation, in accordance with paragraph 5.1 of Annex 13 to the Convention on International Civil Aviation (International Civil Aviation Organization).

This is a class 3 investigation. These investigations analyze a small number of safety issues, and may result in recommendations. Class 3 investigations are generally completed within 450 days. For more information, see the Policy on Occurrence Classification.

TSB investigation process

There are 3 phases to a TSB investigation

  1. Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
  2. Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
  3. Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.

The TSB is an independent agency that investigates air, marine, pipeline, and rail transportation occurrences. Its sole aim is the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability.
