On August 11, 2025, about 1505 Central daylight time, a North American T-28B airplane, N28XT, was substantially damaged when it was involved in an accident near Monticello, Iowa. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to witnesses, the pilot reported, over the Monticello Regional Airport’s Common Traffic Advisory Frequency (CTAF), that he was experiencing a propeller governor failure, and he was returning to the airport. Shortly thereafter, he reported a total loss of engine power, and that he was attempting an emergency landing in a bean field about 2 miles Southeast of the airport (See figure 1). Figure 1.

During the subsequent emergency landing in the bean field, with the landing gear in the retracted position, the airplane continued along the wreckage path for about an additional 275 ft from the initial impact point. The main fuselage, and associated debris path was oriented on about a 217° heading. The debris path between the initial impact point and the main wreckage site displayed signs of extensive fuselage fragmentation. Debris consisting of an engine oil tank and oil cooler, a propeller blade, and the accident airplane’s Wright R-1820 Cyclone 9 engine, were all found in the debris path. The airplane came to rest inverted, which resulted in substantial damage to the fuselage and wings (See figure 2). Figure 2.

An investigator from the National Transportation Safety Board's (NTSB) Alaska Regional Office, along with an NTSB aviation piston engine specialist, responded to the accident site and examined the airplane wreckage on August 12-14. During the detailed on-scene examination, the investigative team retained various components for additional examination and testing, and results are pending. The wreckage has been moved to a secure site and additional postaccident examinations are pending.
