Electrical malfunction

The occurrence

On 25 May 2016, an Air Canada Embraer ERJ 190-100 operating as flight ACA361 from Logan International Airport, Boston, Massachusetts (KBOS), to Lester B. Pearson International Airport, Toronto, Ontario (CYYZ), was en route when both engine-driven electrical generators went offline. The emergency electrical system deployed automatically. The crew followed emergency procedures and successfully reset the electrical generators. The crew landed the aircraft uneventfully. No emergency was declared and there were no injuries reported.

Peter Machete began in aviation in 1977, joining the Canadian Aviation Safety Board, the precursor to the Transportation Safety Board of Canada (TSB), in November 1985.

Mr. Machete left the TSB in May 1996 to go back to the airline industry, and returned to the TSB in May 2003. During his time away, Peter performed maintenance audits on airlines and did insurance surveyor work. He undertook various familiarization courses on several aircraft types and he has numerous license endorsements.

Peter also completed courses in safety management systems for airlines, aircraft retrieval, aircraft performance and structures, and advanced rotary wing investigations.

Transportation Safety Board 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.
