At 18:08 eastern time, a Grumman American AA-5A was damaged during landing at Bowman Field but the two pilots aboard were not injured. The pilot said he had been undergoing instruction for the instrument rating and had completed a lesson. He and the flight instructor were returning to the airport and were cleared for a straight-in approach to runway 19. On final approach, the pilot was instructed to do a go-around due to traffic on the runway. On the downwind leg, he surrendered the flight controls to the CFI. After the CFI landed, the airplane veered to the left, departed the runway and struck railroad ties used to block off a closed taxiway. The CFI said, I dont know if its something I did or didnt do.
