A PA28 PLT HITS THE WAKE OF A BE02 WHILE ON SHORT FINAL APCH AND ROLLS UP TO APPROX 60 DEGS OF BANK BEFORE GOING AROUND.

Narrative

DOING PATTERN WORK AT MVY; WAITING FOR NIGHT TO PRACTICE TKOFS AND LNDGS USING RWY 6. INBOUND; ACR X; A BE1900D; REQUESTED RWY 24. I OFFERED TO MAKE A SHORT APCH TO RWY 6 TO EXPEDITE TFC. AFTER I DID A TOUCH-AND-GO ON RWY 6; TWR CLRED ACR X TO LAND ON RWY 24; THEN CHANGED RWY 'ACTIVE' TO RWY 24. TOLD ME TO ENTER L BASE FOR RWY 24; 'KEEP IT TIGHT BEHIND THE 1900;' WHICH I DID. WIND WAS 140-180 DEGS AT 5 KTS. AT LESS THAN 100 FT AGL; THE ACFT ENTERED A 45-60 DEG BANK (I DON'T RECALL L OR R) AND STALL WARNING CAME ON. I RECOVERED WITH RUDDER AND MADE A NORMAL LNDG/TKOF. I MADE NO MENTION OF THIS TO THE TWR AND CONTINUED IN THE PATTERN WITH A COUPLE OF MORE TOUCH-AND-GOES; THEN 4 NIGHT STOP-AND-GOES. I DIDN'T EXPECT TO GET WAKE TURB OF THIS MAGNITUDE FROM A BEECH 1900 SIZE ACFT; WHICH I ASSUME WEIGHS 15000-20000 LBS. NEXT TIME I WILL PAY CLOSER ATTN TO ANYTHING MORE THAN 2-3 TIMES MY ACFT WT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THIS PLT OF A PIPER PA28-181 ADMITTED THAT HE WAS CLOSE BEHIND A BE1900D; BUT HE SAID THAT HE KNEW THE GENERAL WT OF THAT ACFT AND DID NOT EXPECT TO HAVE A PROB WITH ITS WAKE. THE WINDS WERE LIGHT AND FROM THE SIDE AS HE TURNED FROM BASE TO FINAL; THE RPTR SAID; AND THE BE1900D WAS JUST TOUCHING DOWN. THE RPTR SAID THAT HE STAYED HIGH ON FINAL APCH UNTIL PASSING OVER THE END OF THE RWY. AS THE BE1900D WAS TURNING OFF AT THE END; HE WAS OVER THE NUMBERS AT 100 FT AGL WHEN HE ROLLED SHARPLY TO A 60 DEG BANK. THE STALL WARNING SOUNDED CONTINUOUSLY. HE SAID THAT HE APPLIED RUDDER AND SOME AILERON AND FORWARD PITCH ALONG WITH PWR TO CORRECT THE ROLL AND START HIS GAR. THE ACFT RESPONDED AND DURING THE RECOVERY THE STALL WARNING CEASED. THE RPTR WANTED TO EMPHASIZE THAT HIS PREVIOUS AEROBATIC TRAINING WAS VERY HELPFUL IN HIS RECOVERY. HE REACTED INSTINCTIVELY AND RAPIDLY; HE SAID; AND THAT SAVED HIM. HE SAID THAT ALTHOUGH HE IS NOT A HIGH TIME PLT; HE HAS FLOWN A NUMBER OF ACFT TYPES AND HE DOES MAINTAIN CURRENCY IN THE TYPES THAT HE USES FOR CHARTER AND INSTRUCTION.
