On July 4, 2020, about 1357 eastern daylight time (EDT), an Airbus Helicopter BK117, N263MH, was substantially damaged when it was involved in an accident at Wayne County Airport (KBJJ), Wooster, Ohio. The two commercial pilots, the flight nurse, and flight paramedic sustained no injuries. The helicopter was operated as a Title 14 Code of Federal Regulations (CFR) Part 135 helicopter air ambulance flight.

Surveillance video showed that after lifting off a portable dolly, the helicopter, operated by Metro Aviation, turned right and briefly hovered. As the helicopter began to take off following the hover, it traversed a grassy area adjacent to the ramp about 10 ft above ground level (AGL), where a silt construction fence was obscured by tall grass. As the helicopter overflew, the fence became unsecured and blew up and into the main and tail rotor system as shown in the photo below. The crew then performed a forced landing, which resulted in substantial damage to the fuselage, tailboom, and tail rotor blades.

At the time of the accident, there were no notices to airmen (NOTAMS) for the construction fence and the presence of the fence was not contained within any publications or notices available to pilots.
