A post mortem examination showed three separate medical conditions, which had they been known about by the Civil Aviation medical authorities, could have resulted in the pilot being assessed as unfit for flying duties.

- Improper in-flight decisions,
- Inadequate supervision of flight on part of the pilot-in-command,
- Improper use of equipment,
