According to the instructor’s accident report, the student was making a soft field takeoff on runway 33 with 15 degrees flaps deployed. As the airplane was rotated, it began to drift to the right side of the runway and was slow to gain airspeed because it was in the takeoff configuration. The student pilot lowered the nose in an attempt to increase airspeed, but the airplane continued to drift to the right. The instructor took control, felt resistance in the control yoke, and called for full control. The instructor pulled back on the control yoke to climb in an attempt and clear a house adjacent to the runway. The right wing clipped a portion of the roof, impacted the driveway, and slid across the street, striking a stop sign at a road intersection. Postaccident examination of the airplane failed to show any anomalies that would have precluded normal operation.
