Proceeding on V2 to camps to intercept localizer for runway 2 ILS approach in heavy rain. Cleared by approach from 5000 to 3000' MSL. Told by approach to maintain 3000' till intercepting localizer. I glanced at approach plate, saw the figure 2300 for the localizer approach and, being tired from flying heavy IFR all day, didn't rechk minimum altitudes and started descent. Realized at 2300' I was way below G/south and minimum altitude for that segment of approach. As I started to correct back to 3000' approach control advised me of the altitude and to correct situation, which of course I did. The obvious cause was pilot fatigue. The minimum altitude should have been checked and rechked by me. I knew I was tired. In the future that knowledge will set off mental alarms to avoid the above situation, which could have turned out to be lethal.

Title: FAILED TO COMPLY WITH CLRNC TO MAINTAIN 3000' TO THE LOCALIZER GLIDE SLOPE INTERCEPT.
Narrative: PROCEEDING ON V2 TO CAMPS TO INTERCEPT LOC FOR RWY 2 ILS APCH IN HEAVY RAIN. CLRED BY APCH FROM 5000 TO 3000' MSL. TOLD BY APCH TO MAINTAIN 3000' TILL INTERCEPTING LOC. I GLANCED AT APCH PLATE, SAW THE FIGURE 2300 FOR THE LOC APCH AND, BEING TIRED FROM FLYING HEAVY IFR ALL DAY, DIDN'T RECHK MINIMUM ALTS AND STARTED DSCNT. REALIZED AT 2300' I WAS WAY BELOW G/S AND MINIMUM ALT FOR THAT SEGMENT OF APCH. AS I STARTED TO CORRECT BACK TO 3000' APCH CTL ADVISED ME OF THE ALT AND TO CORRECT SITUATION, WHICH OF COURSE I DID. THE OBVIOUS CAUSE WAS PLT FATIGUE. THE MINIMUM ALT SHOULD HAVE BEEN CHKED AND RECHKED BY ME. I KNEW I WAS TIRED. IN THE FUTURE THAT KNOWLEDGE WILL SET OFF MENTAL ALARMS TO AVOID THE ABOVE SITUATION, WHICH COULD HAVE TURNED OUT TO BE LETHAL.
