Report conserning the serious aircraft incident on 18 May 2014 northeast of Bjørkelangen with Apex Aircraft CAP 10C, LN-KAP
Aviation report 2015/05 eng
During practicing of aerobatic manoeuvres northeast of Bjørkelangen, Akershus, the propeller came loose and disappeared. An emergency landing in an agricultural area was performed without any further damage. The investigation showed that three of the six propeller bolts were broken. The other three bolts were missing and had most likely unscrewed themselves. This indicates that the torque on the bolts was too low.
