C-152 PLT EXPERIENCES LOSS OF ACFT CTL AFTER WAKE TURB ENCOUNTER DURING VISUAL APCH.

Narrative

RETURNING TO BUR; I WAS DIRECTED INTO A STRAIGHT-IN APCH TO RWY 15; AND I WAS NOTIFIED THAT A B-737 WILL PASS ME. I SLOWED THE C-152; WHICH I WAS FLYING; TO OPEN UP THE DISTANCE; AND BY THE TIME I TURNED INTO A 5 MI FINAL; THE B-737 WAS NOT VISIBLE; AND I COULD NOT SEE ITS TOUCHDOWN POINT. AS IS MY HABIT; DUE TO THE AMOUNT OF TFC AT BUR; I ACCELERATED MY APCH TO 105 KTS. I HAD BEEN WARNED 'CAUTION WAKE TURB' WHEN I WAS SEQUENCED; SOME 2 MINS BEFORE; AND I THOUGHT THAT SEPARATION WAS ADEQUATE EVEN THOUGH I WONDERED WHETHER I WOULD STILL FEEL REMNANTS OF WAKE TURB. AT THAT POINT (SOME 4 1/2 MI OUT AT ABOUT 2500 FT MSL; WHERE THE GND IS; ROUGHLY; 1500 FT); THE AIRPLANE WAS LIFTED SUDDENLY AND I WAS THROWN FROM THE SEAT; AND THEN THE AIRPLANE WAS DUMPED SO VIOLENTLY THAT I FOUND MYSELF ALMOST IN A FETAL POS WITH MY EYE-LEVEL BELOW THE INST PANEL. THERE WAS NO ROTATION. AS I RECOVERED; AN IDENTICAL RECURRENCE WAS EXPERIENCED. ALL OF THAT WHILE I WAS ABOVE VA. SINCE THERE WAS NO ROTATION; I BELIEVE IT WAS JET BLAST THAT HAD THE FORM OF TWIN WAVES. MY SOLUTION IS THE FOLLOWING: IF; IN THE PATTERN; WHEN A LARGE AIRPLANE CROSSES THE THRESHOLD; I REQUEST A STANDARD TURN FOR WAKE TURB SEPARATION (2 MINS PLUS). IF ON A STRAIGHT-IN; WHEN THE LARGE AIRPLANE PASSES ME; I MAKE THE SAME REQUEST. I REFUSE TO PROCEED OTHERWISE.
