## Factual narrative (aircraft 2)

On May 28, 2012, about 1604 eastern daylight time, a Beech V35B, N6658R, and a Piper PA-28-140, N23SC, collided in flight in the vicinity of Sumerduck, Virginia. The Beech was destroyed, and the pilot and flight instructor were fatally injured; the Piper was substantially damaged, and the pilot was seriously injured. Neither of the local flights was operating on a flight plan, and both were being conducted under the provisions of 14 Code of Federal Regulations Part 91. Day visual meteorological conditions prevailed. The Beech departed Warrenton-Fauquier Airport, Warrenton, Virginia, on a flight review for the private pilot, and the Piper departed Culpeper Regional Airport, Culpeper, Virginia, on a personal flight. The pilot/owner of the Beech was an employee of the NTSB, and the pilot/owner of the Piper was an employee of the Federal Aviation Administration (FAA). Under the provisions of Annex 13 to the Convention on International Civil Aviation and by mutual agreement, the United States delegated the accident investigation to the government of Canada.
