Narrative:
ATC cleared an SF340 for takeoff from runway 13L while I was approximately 2 NM final for runway 17L. The saab crossed right to left in front of me (approximately 1 NM) and as I crossed runway 13L, at 110 ft radar altitude, I hit his wake. No control problems, just a sharp jolt. This is the first time I have hit a wake while landing runway 17L. However, I have twice hit wakes of runway 17L traffic when departing runway 13L. I feel eventually a turboprop and a large jet will cross paths with serious results.

Title: AN ACR E120 FLC RPT HITTING THE WAKE OF AN SF340 THAT TOOK OFF FROM RWY 13L WHILE THEY WERE ON APCH TO RWY 17L.
Narrative: ATC CLRED AN SF340 FOR TKOF FROM RWY 13L WHILE I WAS APPROX 2 NM FINAL FOR RWY 17L. THE SAAB CROSSED R TO L IN FRONT OF ME (APPROX 1 NM) AND AS I CROSSED RWY 13L, AT 110 FT RADAR ALT, I HIT HIS WAKE. NO CTL PROBS, JUST A SHARP JOLT. THIS IS THE FIRST TIME I HAVE HIT A WAKE WHILE LNDG RWY 17L. HOWEVER, I HAVE TWICE HIT WAKES OF RWY 17L TFC WHEN DEPARTING RWY 13L.
