N3816HErcoupe 415-C · 1947

On September 10, 2019, about 0830 mountain standard time, an Ercoupe 415-C airplane, N3816H, was substantially damaged when it was involved in an accident at the Ak-Chin Regional Airport (A39), Maricopa, Arizona. The student pilot and the flight instructor were seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight.

In a postaccident statement, the flight instructor indicated that he briefed the student pilot on the maneuvers that they would be practicing and had the student describe each maneuver. The briefing also included the instructor’s expectation for a positive exchange of flight controls in the event of an emergency. The student pilot acknowledged this information. The flight instructor and the student pilot then performed the preflight.

According to the flight instructor, the student pilot taxied to the runway, and he was instructed to perform a short-field takeoff. During the takeoff roll, the airplane veered to the left of centerline, and the flight instructor told the student pilot to return to runway centerline. The flight instructor stated that he “corrected three times with the yoke” before the airplane lifted off the ground.

As the airplane reached 65 knots, the student pilot rotated abruptly by “applying a strong amount” of back pressure,” which caused the airplane to pitch up and bank to the left. The flight instructor stated that he yelled, “I have the flight controls” as he applied forward pressure to level the wings, but the airplane did not respond to his control inputs. The flight instructor then looked to his left and saw that the student pilot was still flying the airplane. The flight instructor repeated that he had the flight controls and tried a second time to lower the nose and level the wings, again with no response from the airplane.

The owner of the airplane (and the flight club that owned and maintained the airplane) witnessed the accident. The owner saw the airplane depart from the runway and travel in the direction of the airport’s administration building. The airplane was at an altitude of about 50 ft above ground level, and the engine sounded normal. The airplane then pitched up slightly, rolled to the left, and impacted the roof of the building nose first. The owner further stated that the accident flight was the second training flight for the student pilot in the accident airplane.

Examination of the airplane revealed impact damage to the wings and fuselage. Flight control continuity was established. Postaccident examination of the airframe and engine revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation.
