Aviation Investigation A15O0031
Collision with terrain
On 17 March 2015, a Piper PA-32RT-300T, with three people on board departed Sudbury, Ontario, on an IFR flight to Winston-Salem, North Carolina. Approximately 30 NM south of Sudbury at an altitude of 10,000 feet the pilot turned the aircraft back and advised Air Traffic Control that the flight was returning. This was the last radio communication from the pilot and no reason was specified for the return. ATC cleared the aircraft to a lower altitude and observed it turning and descending on radar. During the descent the aircraft disappeared from radar at 8800 feet then reappeared momentarily at 6300 feet after which there were no further radar contacts. Moments later there was a brief signal from the aircraft's Electronic Locator Transmitter which ended abruptly. The aircraft was located the following morning. All three people on board were fatally injured. The aircraft suffered an in-flight breakup and debris was found over an area covering approximately 1.25 NM. A post-crash fire destroyed most of the main wreckage.

Transportation Safety Board investigation process
There are 3 phases to a TSB investigation:
- Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
- 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.
- 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.
