Brindabella Airlines grounds planes for 'maintenance review' A Brindabella Airlines plane at Canberra Airport. REGIONAL airline service Brindabella has taken four planes out of service while it undertakes a "maintenance review." The planes were voluntarily removed from service on Friday night. It's understood the Civil Aviation and Safety Authority was made aware of the decision by the airline. Qantas, which in July signed a codeshare agreement with the airline, has suspended the arrangement until the issue is resolved. Founded in 1994, the popular country airline conducts over 280 flights per week to Brisbane, Canberra, Cobar, Cooma, Coffs Harbour, Moree, Mudgee, Narrabri, Newcastle, Orange, Sydney and Tamworth. Four of the airline's 10-strong fleet were taken out of service. An industry source said three of the four planes were in service at the time of the decision. "The airline is undertaking a maintenance review," the industry source said. The planes should be back in service by Tuesday or Wednesday. Brindabella officials were unavailable for comment. A Qantas spokesman said the airline would service two of the affected routes between Brisbane and Tamworth and Sydney and Moree. "We will be putting on a dozen planes on affected routes," he said.
