Australia has grounded its Eurocopter Tiger attack helicopters after fumes were detected in one of the aircraft.
"The Australian Army has suspended Tiger armed reconnaissance helicopter flying operations for training activities due to a concern following the detection of fumes in the cockpit of one of the aircraft," says Australia's department of defence.
The force has 22 Tigers, but the type has yet to enter full operational service. Of these, 19 have a "fully capable configuration" and three are being retrofitted.
Final testing of the type is planned for late 2012.
