but I am aware that this company did not enforce the policy of Jepessen charts
1.8.3 Instrument approach charts
Pilots employed by Transair were expected to use charts produced by Jeppesen and both pilots of VH-TFU held current subscriptions to the Jeppesen chart amendment service. Although those charts were produced by Jeppesen, they were developed from data published by Airservices Australia. Due to the impact damage and postimpact fire, the investigation was unable to conclusively determine whether both pilots were carrying and using the appropriate charts for the flight.
