Hayward ATIS was reporting 300 ovc because of fog. The ovc was dropping rapidly. I shot the localizer DME 28L approach into hwd. The MDA for the approach is 400 MSL. The map is 0.9 DME on the localizer frequency. During the approach I asked hayward tower how the plane just ahead of me completed the approach. He said the plane had trouble seeing the runway. As I shot the approach at 0.9 DME and 400' MSL, I could not see the airport. The tower asked if I could see the mall just east of the runway. I said negative. While I was looking down for landmarks and the runway environment, I descended below the MDA (400'). Shortly after 0.9 DME I saw the approach end of the runway and did a circle to land. At the MDA and map I should have done the missed instead of relying on visual cues. Switching from instruments to looking outside to the ground caused me to bust the MDA. Next time I will not go any further down if I don't have any runway environment in sight. This was a very scary and stupid experience.

Title: SMA PLT DESCENDS BELOW MDA ON LOC DME RWY 28L AT HWD.
Narrative: HAYWARD ATIS WAS REPORTING 300 OVC BECAUSE OF FOG. THE OVC WAS DROPPING RAPIDLY. I SHOT THE LOC DME 28L APCH INTO HWD. THE MDA FOR THE APCH IS 400 MSL. THE MAP IS 0.9 DME ON THE LOC FREQ. DURING THE APCH I ASKED HAYWARD TWR HOW THE PLANE JUST AHEAD OF ME COMPLETED THE APCH. HE SAID THE PLANE HAD TROUBLE SEEING THE RWY. AS I SHOT THE APCH AT 0.9 DME AND 400' MSL, I COULD NOT SEE THE ARPT. THE TWR ASKED IF I COULD SEE THE MALL JUST E OF THE RWY. I SAID NEGATIVE. WHILE I WAS LOOKING DOWN FOR LANDMARKS AND THE RWY ENVIRONMENT, I DESCENDED BELOW THE MDA (400'). SHORTLY AFTER 0.9 DME I SAW THE APCH END OF THE RWY AND DID A CIRCLE TO LAND. AT THE MDA AND MAP I SHOULD HAVE DONE THE MISSED INSTEAD OF RELYING ON VISUAL CUES. SWITCHING FROM INSTRUMENTS TO LOOKING OUTSIDE TO THE GND CAUSED ME TO BUST THE MDA. NEXT TIME I WILL NOT GO ANY FURTHER DOWN IF I DON'T HAVE ANY RWY ENVIRONMENT IN SIGHT. THIS WAS A VERY SCARY AND STUPID EXPERIENCE.
