On November 17, 2025, about 0830 mountain standard time, a Piper PA 28-181, N4402N, was substantially damaged when it was involved in an accident near Mesa, Arizona. The flight instructor and student pilot were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight. The flight instructor reported that after a training flight they had returned to Falcon Field Airport (FFZ), Mesa, Arizona, where they then conducted 3 touch and go landings and a go-around. They continued their training in the traffic pattern and were in an extended downwind for runway 4L. After entering the base leg of the traffic pattern and as they were preparing for the approach, an uncommanded reduction of power occurred. The flight instructor took control of the airplane and advanced the mixture lever and moved the throttle lever; however, he was unable to restore engine power. The flight instructor soon realized they would not make the runway and assessed the limited landing options. He subsequently made a forced landing on a gravel road that paralleled a water canal. After landing, about 100 yards into the landing roll, the right wing collided with a cinder block fence and the airplane came to rest. The airplane sustained substantial damage to the fuselage, left stabilizer and both wings. The airplane was recovered to a secure location for further examination.
