An airplane on an ILS approach to Runway 16 deviated from the localizer and descended below the glide path. The controller warned the pilot, but the aircraft struck a tree at 600 ft MSL, after last radar contact at 700 ft.

Approach and Controller Warnings

The airplane was conducting an instrument landing system (ILS) approach to Runway 16. During the approach, radar controllers observed the aircraft deviate from the localizer course, first to the left and then to the right. The controller issued warnings to the pilot about these deviations and additionally alerted the pilot that the aircraft was 300 feet too low relative to the normal glide path.

Final Descent

Radar contact was lost when the airplane was at 700 feet mean sea level (MSL) and positioned to the right of the localizer course. The ground elevation at the accident site was 600 feet MSL. The airplane subsequently struck a tree that was approximately 100 feet tall. Weather conditions at the time included partial obscuration and visibility of one-quarter mile.

Pilot Experience

The pilot had accumulated a total of 40 simulated instrument flight hours and 32 night flight hours at the time of the event.
