ASRS report 196447

Narrative

I WAS PF. MY FO WAS COMMUNICATING WITH PHL APCH. WE WERE BEING VECTORED FOR APCH TO PHL. I ESTIMATE WE WERE #4 IN LINE WITH THE ARR CTLR. PHL WAS LNDG E ON RWY 9R AND WE WERE NNW OF THE ARPT HDG 080. THE CTLR GAVE US A TURN TO 070. I HEARD HIM TO SAY 170. MY FO READ BACK 070; BUT I ONCE AGAIN HEARD 170. MY FO WAS USING A BOOM MICROPHONE THAT WAS TOUCHING HIS LIPS. I BELIEVE THIS WAS A FACTOR IN THAT IT MUFFLED HIS WORDS A LITTLE BIT. I TURNED TO 170 DEG WHILE MY FO ATTENDED TO OTHER DUTIES. HE STATED THAT HE WAS REVIEWING THE APCH CHART. I HAD BEEN STEADY ON THE 170 HDG FOR ABOUT 30 SECONDS WHEN THE CTLR ADVISED THAT HE HAD GIVEN US A 070 HDG. HE QUICKLY DETERMINED THAT THE BEST MOVE WAS TO KEEP US ON THAT HDG TO ENTER US INTO A BASE LEG SET UP FOR THE 9R LOC. HE MADE A HOLE BY SLOWING AND TURNING ACFT THAT WERE COMING IN FROM OUR L. THE REST OF THE APCH WAS UNEVENTFUL. UPON ARR AT THE GATE I PHONED APCH CTL TO COMPLIMENT THE CTLR ON HIS HANDLING OF THE SITUATION AND EXPLAIN WHAT HAPPENED. HE WAS A CTLR UNDER TRAINING; WHICH MADE IT EVEN MORE IMPRESSIVE. THE SUPVR STATED THAT NO CONFLICT EXISTED WITH OTHER TFC AT ANY TIME. THIS WAS A MATTER OF LUCK; SO IT COULD EASILY HAVE BEEN HAZARDOUS. I HAD A DISCUSSION WITH MY FO REGARDING VERIFICATION OF CTLRS INSTRUCTIONS AND ENSURING THAT THE PF COMPLIES WITH THE INSTRUCTIONS. IT IS PART OF THE PNF DUTIES HE WAS TRAINED TO PERFORM. I BELIEVE I WILL REPEAT HDG ASSIGNMENT IN THE FUTURE JUST AS I REPEAT ALT ASSIGNMENTS NOW.; I was taxing the 1946 Aeronca Champ (tailwheel) to the end of Runway XX at ZZZ. The wind was between 60 and 70 degrees and 8-10 knots. This would be a quartering tailwind for the taxiway. I had the appropriate control inputs in place. I realized I was taxiing faster than I should have due to the taxiway sloping downhill just prior to the turn to the runway. I attempted to break but with the heel style brakes I believe I had too much pressure on the brakes and not enough rudder input and began to veer to the right. When I realized this I put full left brake and rudder but it did not stop the airplane from going off the taxiway and hitting a taxi light. Miraculously there was no prop strike and no damage to the airplane at all. I called the airport and spoke to the ramp person in charge at the time and explained the situation and they said they would go out and take a look at it. I asked if there was any further action required from me and he said no there would not be. I believe the way to prevent a similar event in the future would be to taxi at a slower pace
