Background
The aircraft was being ferried under visual flight rules by its owner. Before departure, repairs were made to the radios. However, the glide slope receiver was found to be inoperative at that time. During a fuel stop en route, the weather forecast for the destination indicated that instrument flight rules conditions would be in effect.
Flight Details
To comply with the IFR conditions, the owner hired an instrument flight instructor for the remaining portion of the flight. The owner showed a work order to the certified flight instructor, who incorrectly interpreted it as evidence that the glide slope had been repaired. The CFI later recalled that the destination weather forecast included a ceiling of 600 feet.
Approach
According to records, there was no indication that the CFI had obtained the current weather at the destination, which was reported as a 200-foot ceiling and 1-1/4 miles visibility, before initiating the approach. The CFI stated that a descent rate of 500 feet per minute at an airspeed of 90 knots was used during the approach. While flying the ILS runway 36 approach, the CFI pointed out to the owner that both the localizer and glide slope needles were centered when the aircraft was approximately 2 miles from the runway.
Post-Crash Findings
A test conducted after the accident on the glide slope receiver showed that it was still inoperative, indicating that the earlier condition had not been rectified.
