Narrative:
A Volpar Turboliner II, a stretched turbine conversion of a Beechcraft C-45 Expeditor, crashed during the approach to Baltimore/Washington International Airport, Maryland. The pilot was killed.
The airplane operated on a cargo flight from Dayton, Ohio.
Prior to departure, the pilot supervised the loading of the airplane. The plane was loaded to a gross weight of 11,979 lb with the cg 2.7 inches behind the aft limit. At the destination, the flight was vectored for an ILS runway 10 approach. About 3 miles from the runway, the pilot was told to make a missed approach due to inadequate separation from traffic. The pilot acknowledged, but soon thereafter, radar contact with the plane was lost. Witnesses saw the plane descend from a low cloud layer before it crashed. There was evidence the plane impacted in a flat attitude with little forward movement. Four cargo straps were found loose with no sign of tensile overload; 3 others and a restraining board were found loose as if they had not been used. No preimpact mechanical problem was found.

Probable Cause:

The National Transportation Safety Board determines the probable cause(s) of this accident as follows: "Failure of the pilot to properly secure the cargo, which allowed a shift in the center of gravity during a missed approach maneuver and resulted in subsequent loss of aircraft control and flying speed. A factor related to the accident was failure of the pilot to assure the airplane was loaded within its proper weight and balance limitations."
