Occurrence Briefs are concise reports that detail the facts surrounding a transport safety occurrence, as received in the initial notification and any follow-up enquiries. They provide an opportunity to share safety messages in the absence of an investigation.
On 27 February 2019, at approximately 1800 Western Standard Time, a Cessna 172M with one pilot on board was conducting a private flight from Lindon, Western Australia (WA) to Carnarvon, WA. During cruise at approximately 6,000 ft, the pilot heard a loud bang and observed oil on the windscreen of the aircraft. The engine subsequently ran rough for two minutes before failing completely. The pilot located an appropriate landing area at Middalya Station, WA and conducted a forced landing. The pilot was uninjured and there was no damage to the aircraft as a result of the forced landing. The engineering inspection determined that one cylinder in the engine had broken in half.
This incident highlights the importance of frequent emergency procedures training. The pilot’s handling of the forced landing contributed positively to the outcome of this incident. The ATSB investigation report, Engine failure and forced landing involving Gippsland GA-8 Airvan, VH-BFL, 8.5 km NNW or Bellburn Airstrip Western Australia, on 15 May 2018 (AO-2018-036) states, ‘Although, as a minimum, flight reviews are required every two years, pilots and operators are reminded of the benefits of more frequent practice of emergency procedures.’
