[[File:"Alitalia" I-BIKE (3097537511).jpg|thumb|250x250px|I-BIKE, the aircraft involved in the A320 incident]]
On 25 June 2005, an [[Alitalia]]<!-- see http://www.baaa-acro.com/Photos-27/I-BIKE.jpg --> [[Airbus A320-200]] registered as I-BIKE departed [[Milan]] with a defective ADIRU as permitted by the [[Minimum Equipment List]]. While approaching [[London Heathrow Airport]] during deteriorating weather another ADIRU failed, leaving only one operable. In the subsequent confusion the third was inadvertently reset, losing its reference heading and disabling several automatic functions. The crew was able to effect a safe landing after declaring a [[Pan-pan]].<ref>{{cite web

On 1 August 2005, a serious incident involving [[Malaysia Airlines]] Flight 124 occurred when an ADIRU fault in a [[Boeing 777|Boeing 777-2H6ER]] (9M-MRG) flying from [[Perth Airport|Perth]] to [[Kuala Lumpur International Airport|Kuala Lumpur International]] caused the aircraft to act on false indications, resulting in uncommanded manoeuvres.<ref>{{ASN accident | id = 20050801-1 | title = Malaysia Airlines Flight 124 | accessdate = 2008-10-15}}</ref> In that incident the incorrect data impacted all [[flight dynamics|planes of movement]] while the aircraft was climbing through {{convert|38000|ft|m|-2}}. The aircraft pitched up and climbed to around {{convert|41000|ft|m|-2}}, with the stall warning activated. The pilots recovered the aircraft with the autopilot disengaged and requested a return to Perth. During the return to Perth, both the left and right autopilots were briefly activated by the crew, but in both instances the aircraft pitched down and banked to the right. The aircraft was flown manually for the remainder of the flight and landed safely in Perth. There were no injuries and no damage to the aircraft. The ATSB found that the main probable cause of this incident was a latent software error which allowed the ADIRU to use data from a failed [[accelerometer]].<ref>
