Investigation in progress

Summary

The ATSB is investigating an depressurisation and crew incapacitation involving a B737, VH-XMO, near Narrandera NSW, 15 August 2018.

During cruise, the crew of the cargo flight received a wing body overheat warning resulting in a reduction of cabin pressure. The crew donned oxygen and descended to 20,000 ft. The First Officer was subsequently incapacitated and the Captain descended to 8,000 ft and diverted the aircraft to Canberra.

As part of the investigation, the ATSB will collect and examine information from the aircraft’s flight data recorders and interview maintenance and flight crew.

A final report will be released at the end of the investigation.

Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify those affected and seek safety action to address the issue.
