Analysis

The Piper PA-23-250 attempted a go-around after crossing the threshold and observing the runway lights were not on during a night instrument approach. The pilot reported that he added full power and retracted the wing flaps. The procedure in the Piper manual is to add full power, retract the landing gear, and then slowly retract the wing flaps. The aircraft made ground contact with the landing gear still extended and it passed through a drainage ditch.
