NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

During the instrument flight rules initial climb after takeoff, in fog, to visual conditions on top, the airplane collided with the ground about 1 mile from the departure runway. Prior to departure on runway 11, the pilot contacted the control tower to request the instrument departure to on-top and was advised to standby. During the course of communication the pilot was advised the "tops" were 300 feet above ground level, and was issued a clearance to taxi to the runway. The tower advised the pilot that they were closing and to contact ARTCC for release. The pilot obtained the IFR clearance and was released to on-top. The pilot's release included a standard instrument departure that required a right turn to 130 degrees after departure. There was no further communication with the pilot and radar contact was never established. The airplane subsequently collided with the ground, south of the runway, in a steep right wing down attitude on a magnetic heading of 180 degrees. Examination of the airplane wreckage did not reveal any system anomalies. The vacuum pump drive shear-shaft was found intact and there was rotational scoring of the attitude indictor gyroscope rotor.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain a proper climb rate to VFR conditions on-top.
