Event Summary

On an unspecified date, two aircraft were involved in a collision on a taxiway. The incident occurred after one aircraft landed and the other was taxiing for takeoff. No injuries were reported, and the investigation is ongoing.

Sequence of Events

Aircraft N49985 landed on runway 32 and turned off the runway at a midfield intersection. After clearing the runway, the aircraft came to a full stop to retract the flaps and turn off the carburetor heat. The pilot reported that a check for other traffic was made at this time. The student pilot then began taxiing toward the ramp with the landing light off, while the navigation lights and beacon were on.

Meanwhile, aircraft N8172 was taxiing to runway 32 for takeoff. The pilot of N8172 stated that he observed N49985 land and take the first taxiway turnoff. He reported that he was making 'S' turns during taxi but did not see N49985 turn onto the taxiway.

As N49985 proceeded along the taxiway, the certified flight instructor (CFI) on board initiated a sharp right turn upon seeing N8172 approaching. Despite this evasive action, the CFI was unable to prevent a collision. The nose section of N8172 contacted the left side of N49985.

Aircraft and Pilot Information

N49985 was operated by a student pilot with a CFI on board. N8172 was under the control of a pilot who was taxiing for departure. The specific aircraft types and engine configurations were not provided.

Investigation Notes

The investigation into the collision is based on pilot statements. The pilot of N8172 noted that he was making 'S' turns, a technique used to improve visibility from the cockpit, but still did not see N49985 enter the taxiway. The pilot of N49985 reported conducting a traffic check before resuming taxi. The collision occurred despite the CFI's evasive maneuver.
