Narrative:

There was a misunderstanding in what the controller said and what the crew thought the controller said. We were approaching memphis on a heading to intercept the VOR runway 27 approach in a descent from 3000 ft to 2000 ft. When the approach clearance was given, the crew also understood the controller wanted at least 180 KTS until 5 DME. Therefore, the crew kept their speed up. Shortly after, the controller asked us our speed and we said 200 KTS. He told us he said 180 KTS until 5 DME. Therefore, we slowed to 180 KTS.

Title: FLC SPD DEV ON DSCNT PROC, APCH TO MEM IN A BA31.

Narrative: THERE WAS A MISUNDERSTANDING IN WHAT THE CTLR SAID AND WHAT THE CREW THOUGHT THE CTLR SAID. WE WERE APCHING MEMPHIS ON A HEADING TO INTERCEPT THE VOR RWY 27 APCH IN A DSCNT FROM 3000 FT TO 2000 FT. WHEN THE APCH CLRNC WAS GIVEN, THE CREW ALSO UNDERSTOOD THE CTLR WANTED AT LEAST 180 KTS UNTIL 5 DME. THEREFORE, THE CREW KEPT THEIR SPD UP. SHORTLY AFTER, THE CTLR ASKED US OUR SPD AND WE SAID 200 KTS. HE TOLD US HE SAID 180 KTS UNTIL 5 DME. THEREFORE, WE SLOWED TO 180 KTS.
