On 7 October 2008 , Qantas Flight 72 made an emergency landing at Learmonth airport near the town of Exmouth , Western Australia following an inflight accident featuring a pair of sudden uncommanded pitch-down manoeuvres that resulted in serious injuries to many of the occupants . The Australian Transport Safety Bureau ( ATSB ) identified in a preliminary report that a fault occurred within the Number 1 Air Data Inertial Reference Unit ( ADIRU ) and is the " likely origin of the event " . The ADIRU — one of three such devices on the aircraft — began to supply incorrect data to the other aircraft systems . The ATSB 's continuing accident investigation will include assessment of speculation that possible interference from Harold E. Holt facility or passenger personal electronic devices could have been involved , although based on initial analysis , the Bureau believes these are unlikely to have been of any impact
