The MIG 21 Lancer plane crashed because of a human error, according to the commission that probed the plane accident which occurred on November 1 last year, near Campia Turzii, Realitatea.net reports. Both pilots aboard the plane – Sorin Avram and Laurentiu Chirita – died in the crash. According to the findings of the commission, the pilots decided to start their last maneuver at the wrong altitude. “The probe has been completed and the commission reached the conclusion that the last maneuver – the vertical climb, loop and return to normal flight – was made at a lower altitude than provided by flight manuals. The pilots probably were blinded by the sun and did not correctly read the onboard altimeter. The conclusion is that the accident was caused by human error,” said, Lt. Col. Liviu Lascu, prosecutor with the Military Prosecutor’s Office of Cluj, quoted by stiridecluj.ro. Investigators believe that, because of the high speed, the plane began to vibrate and stalled.
