What happened
While arriving at the destination airport, the pilot was executing an ILS runway 5R approach following radar vectors. During the final approach course, air traffic control issued course correction instructions to the pilot. However, the aircraft exhibited erratic movement that continued until it descended and disappeared from radar coverage. A witness located near the accident site observed the airplane falling from the sky in several pieces.
The investigation

Findings
A physical examination of the wreckage failed to disclose any mechanical or system malfunction or component failure.
