Analysis

At the end of a cross country flt, while in the pattern turning from base to final, the plt stated that the arpt environment was lost. At the same time, the instrument white lights, under the glareshield began to flicker which drowned out the normal instrument lighting. The plt does not remember the occurrences from aprx 1000 ft AGL while turning to final to the time the acft collided with the terrain, aprx 1 mile short of the rwy. Other than the flickering lights, there were no other mechanical failures or malfunctions reported.
