Event Description
While conducting a coupled Instrument Landing System (ILS) approach to runway 35, the flight crew encountered anomalies in the navigation indicators. At approximately 100 feet above the decision height, the localizer bar deflected fully to the right and the glideslope flag appeared. The aircraft subsequently executed a hard right turn. The pilot countered the turn by rotating the yoke to the left. Immediately thereafter, the localizer bar deflected fully to the left, and the aircraft attempted to follow the displacement while continuing its descent. The pilot again applied opposite yoke input and simultaneously located the autopilot disconnect button on the yoke.
During the attempted climb, the aircraft struck a light pole located approximately 1.5 miles from the departure end of runway 35. The impact caused substantial damage to the nose landing gear wheel assembly and the left wing spar.
Post-Event Examination
Following the incident, the Federal Aviation Administration (FAA) conducted an examination of the ILS installation. The inspection revealed that the glideslope equipment was out of service at the time of the approach. However, the localizer, outer marker, and middle marker equipment were found to be operational.
Damage Assessment
The aircraft sustained substantial damage to the nose landing gear wheel assembly and the left wing spar as a result of the collision with the light pole.
