The Australian Civil Aviation Safety Authority (CASA) has directed regional air carrier Brindabella Airlines to conduct maintenance reviews on six of its aircraft.
These aircraft may not be flown until the maintenance reviews are completed and CASA has given approval for their return to service. In November 2013 CASA directed Brindabella to conduct maintenance reviews on four Jetstream aircraft. Two of these aircraft are now approved for service.
The latest direction, which takes effect from on Saturday 14 December 2013, ensures that any outstanding maintenance related issues have been addressed on all Brindabella aircraft.
CASA initially required the reviews on the four Jetstream aircraft after finding Brindabella had overrun engine inspections. Since then CASA has identified additional inspection and maintenance overruns, leading to the decision to require the six Jetstream and Metroliner additional aircraft to be reviewed.
