The Australian Transport Safety Bureau (ATSB) is investigating an in-flight propeller loss involving Jabiru J170, registered 24-7496, that occurred 2.6 km north-east of Muchea, Western Australia on 22 December 2021.

During a missed approach and go-around, the propeller separated from the aircraft and the pilot conducted a forced landing into a paddock. There were no injuries reported.

As part of the investigation, ATSB investigators will examine recovered physical components, relevant maintenance documentation, and interview the pilot and witnesses.

Decisions regarding whether to conduct an investigation, and the scope of an investigation, are based on many factors, including the level of safety benefit likely to be obtained from an investigation. The Jabiru J170 is an Australian manufactured aircraft, often used for flight training, and can be registered with either the Civil Aviation Safety Authority or Recreational Aviation Australia.

A final report will be released at the conclusion of the investigation. However, should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate safety action can be taken.
