Narrative:
On final approach into stl, we were the third airplane in a tight landing sequence. The airplane ahead of us was doing s-turns on final for spacing with the airplane ahead of him. We had slowed to our final approach speed for spacing. The airplane ahead of us landed and was turning off the runway. When we were at 100 ft AGL, the airplane ahead of us was clear of the runway, then we heard a blocked transmission from an air carrier flight XXX. We landed uneventfully. After landing, ground control asked us to call the tower on the phone. The captain spoke with the tower controller and the controller informed him that he had issued a 'go around' to us. The captain told the controller that we did not hear the transmission because of a blocked call. This could have been prevented if approach control would've spaced the planes wider. We may have heard the go around transmission if the controller would have tried again over the blocked call. The landing was completed safely and there was no conflict with the plane in front of us. Supplemental information from acn 420049: it looked as if a go around might be required. As we crossed the end of the runway, it appeared to me the aircraft ahead would clear the runway before we touched down. As I started my flare, there was a radio transmission which was totally unintelligible and garbled. I found out later the tower controller had issued go around instructions which were apparently blocked by an aircraft checking in on the frequency. By the time we touched down the other aircraft was clear of the runway.
Original NASA ASRS Text
Title: CAPT OF AN MLG LANDED AFTER THE TWR ISSUED GAR INSTRUCTIONS DUE TO ANOTHER ACFT ON THE RWY. HOWEVER, THE TWR'S XMISSION WAS BLOCKED BY ANOTHER ACFT CALLING IN AND THE RPTR NEVER HEARD THE GAR. THEY HAD ASSESSED THE ACFT THAT LANDED BEFORE THEM AND NOTED THAT HE WAS CLRING THE RWY AS RPTRS WERE TOUCHING DOWN.
Narrative: ON FINAL APCH INTO STL, WE WERE THE THIRD AIRPLANE IN A TIGHT LNDG SEQUENCE. THE AIRPLANE AHEAD OF US WAS DOING S-TURNS ON FINAL FOR SPACING WITH THE AIRPLANE AHEAD OF HIM. WE HAD SLOWED TO OUR FINAL APCH SPD FOR SPACING. THE AIRPLANE AHEAD OF US LANDED AND WAS TURNING OFF THE RWY. WHEN WE WERE AT 100 FT AGL, THE AIRPLANE AHEAD OF US WAS CLR OF THE RWY, THEN WE HEARD A BLOCKED XMISSION FROM AN ACR FLT XXX. WE LANDED UNEVENTFULLY. AFTER LNDG, GND CTL ASKED US TO CALL THE TWR ON THE PHONE. THE CAPT SPOKE WITH THE TWR CTLR AND THE CTLR INFORMED HIM THAT HE HAD ISSUED A 'GAR' TO US. THE CAPT TOLD THE CTLR THAT WE DID NOT HEAR THE XMISSION BECAUSE OF A BLOCKED CALL. THIS COULD HAVE BEEN PREVENTED IF APCH CTL WOULD'VE SPACED THE PLANES WIDER. WE MAY HAVE HEARD THE GAR XMISSION IF THE CTLR WOULD HAVE TRIED AGAIN OVER THE BLOCKED CALL. THE LNDG WAS COMPLETED SAFELY AND THERE WAS NO CONFLICT WITH THE PLANE IN FRONT OF US. SUPPLEMENTAL INFO FROM ACN 420049: IT LOOKED AS IF A GAR MIGHT BE REQUIRED. AS WE CROSSED THE END OF THE RWY, IT APPEARED TO ME THE ACFT AHEAD WOULD CLR THE RWY BEFORE WE TOUCHED DOWN. AS I STARTED MY FLARE, THERE WAS A RADIO XMISSION WHICH WAS TOTALLY UNINTELLIGIBLE AND GARBLED. I FOUND OUT LATER THE TWR CTLR HAD ISSUED GAR INSTRUCTIONS WHICH WERE APPARENTLY BLOCKED BY AN ACFT CHKING IN ON THE FREQ. BY THE TIME WE TOUCHED DOWN THE OTHER ACFT WAS CLR OF THE RWY.
