Analysis narrative
The pilot was conducting an ils approach to runway 11, at night. The reported visibility was 8 miles with light rain. He dropped below the glide path and struck an approach light tower about 1/4 mile from the runway threshold. The pilot had not flown at night in about 90 days. Also, he had only flown about 4 times in this period. Examination revealed no discrepancies with the engines, and the ils was flight tested satisfactorily. A witness observed the airplane 'on a gradual decline...hit the pole.'
