Narrative:

While repositioning a helicopter from one FBO to another on the orlando-sanford airport, I thought I heard the tower controller tell me to 'turn across a runway now.' I did, and he said he didn't tell me to cross. He also said he had landing traffic, but there was no conflict. I would not have crossed an active runway unless I thought I had been told to. Maybe other traffic on the frequency cut out part of his transmission.

Original NASA ASRS Text

Title: HELI CROSSES RWY WITHOUT CLRNC AT SFB, FL.

Narrative: WHILE REPOSITIONING A HELI FROM ONE FBO TO ANOTHER ON THE ORLANDO-SANFORD ARPT, I THOUGHT I HEARD THE TWR CTLR TELL ME TO 'TURN ACROSS A RWY NOW.' I DID, AND HE SAID HE DIDN'T TELL ME TO CROSS. HE ALSO SAID HE HAD LNDG TFC, BUT THERE WAS NO CONFLICT. I WOULD NOT HAVE CROSSED AN ACTIVE RWY UNLESS I THOUGHT I HAD BEEN TOLD TO. MAYBE OTHER TFC ON THE FREQ CUT OUT PART OF HIS XMISSION.
