Narrative:

Landing in pit on runway 10R in a BAE3100. On short final I was caught in wake turbulence from another aircraft (DO328). My aircraft rolled left violently. When leveling the wings the stall shaker and pusher came on. I over pwred the pusher as best I could and advanced full power -- this did not stop the descent. The plane hit the runway hard, may have been short of the runway. I believe I was inadvertently below the GS. I wasn't real cautious due to VMC conditions and underestimating the wake potential of a DO328. Fatigue was also a possible factor. I was on the 7TH leg of a 10 leg day, 14 hours on duty. Initial fear kept me from reporting the incident (of prosecution).

Title: AN ACR BA31 FLC HIT THE WAKE OF A DO328 WHILE ON SHORT FINAL APCH TO RWY 10R.

Narrative: LNDG IN PIT ON RWY 10R IN A BAE3100. ON SHORT FINAL I WAS CAUGHT IN WAKE TURB FROM ANOTHER ACFT (DO328). MY ACFT ROLLED L VIOLENTLY. WHEN LEVELING THE WINGS THE STALL SHAKER AND PUSHER CAME ON. I OVER PWRED THE PUSHER AS BEST I COULD AND ADVANCED FULL PWR -- THIS DID NOT STOP THE DSCNT. THE PLANE HIT THE RWY HARD, MAY HAVE BEEN SHORT OF THE RWY. I BELIEVE I WAS INADVERTENTLY BELOW THE GS. I WASN'T REAL CAUTIOUS DUE TO VMC CONDITIONS AND UNDERESTIMATING THE WAKE POTENTIAL OF A DO328. FATIGUE WAS ALSO A POSSIBLE FACTOR. I WAS ON THE 7TH LEG OF A 10 LEG DAY, 14 HRS ON DUTY. INITIAL FEAR KEPT ME FROM RPTING THE INCIDENT (OF PROSECUTION).
