Accidents & Serious Incidents involving AT45

  • AT45 / B733, Munich Germany, 2004 (During the hours of darkness at Munich on 3 May 2004, an ATR42-500 was given a conditional line up clearance for Runway 08R but contrary to this clearance then taxied onto that runway as a Boeing 737-300 was landing on it. The landing aircraft missed the right wingtip of the ATR-42, which continued taxing onto the runway as it approached, by “a few metres”.)
  • AT45, Sienajoki Finland, 2006 (On 11 December 2006, a Finnish Commuter Airlines ATR 42-500 veered off the runway on landing at Seinäjoki, Finland.)
  • AT45, vicinity Prague Czech Republic, 2012 (On 31 October 2012, the crew of an ATR42 on a handover airworthiness function flight out of Prague briefly lost control in a full stall with significant wing drop after continuing a prescribed Stall Protection System (SPS) test below the appropriate speed and then failing to follow the correct stall recovery procedure. Failure of the attempted SPS test was subsequently attributed to both AOA vanes having become contaminated with water during earlier aircraft repainting at a specialist contractor and consequently being constrained in a constant position whilst the SPS test was being conducted at well above the prevailing freezing level.)
  • AT45, vicinity Sienajoki Finland, 2007 (On 1 January 2007, the crew of a ATR 42-500 carried out successive night approaches into Seinajoki Finland including three with EGPWS warnings, one near stall, and one near loss of control, all attributed to poor flight crew performance including use of the wrong barometric sub scale setting.)
