PROBABLE CAUSE: "The accident was attributed to a maintenance error resulting from inadequate inspection periodic, daily, nightly and transit servicing and consisting in failure to notice the absence of a pin looseness and/or absence of a nut which joins the torsion links of the left landing gear. A possible contributing factor in the accident was pilot error, consisting in involuntary negligence in observing or wrongly interpreting the aircraft instruments during takeoff, at the time of changing over from VFR to IFR flight and/or loss of control of the aircraft by the pilot-in-command when checking the cause of a failure in the landing gear well and no.2 engine.".
