The Australian budget airline is at risk of being grounded by the Civil Aviation Safety Authority over a series of serious safety and maintenance breaches. Complaints were made by passengers and CASA has issued a “show cause” notice on March 23 giving the airline 21 days to respond. This is the most serious action taken by CASA against a major Australian airline since Ansett was hit with a similar warning in 2001 of which the airline subsequently went bankrupt. CASA raised concerns to Tiger’s Melbourne-based management of its lack of following proper procedures to ensure utmost safety of passengers. For the past two years, Tiger has been ranked last in Australia’s Choice survey of domestic airlines.
