On December 10, 2016, about 1130 central standard time, a Hiller OH-23B helicopter, N5776, impacted terrain during a practice autorotation near Tynan, Texas. The student pilot, who was the sole occupant, sustained serious injuries, and the helicopter was destroyed due to a post-impact fire. The helicopter was registered to Tynan Flyers, LLC, Tynan, Texas, and operated by a private individual as a 14 Code of Federal Regulations Part 91 instructional flight. Visual meteorological conditions prevailed at the time of the accident and a flight plan was not filed. The local flight departed a private residence about 1000.

The student pilot reported he departed a private residence on his second solo flight. Prior to the accident, he completed two takeoffs and landings without incident. During a practice autorotation, the tail rotor struck the ground, the helicopter entered a spin, and came to rest near the place of initial impact. The student pilot reported there were no mechanical or system malfunctions with the helicopter prior to the accident. 

According to the student pilot's flight instructor who witnessed the accident, the student pilot appeared to be conducting a practice autorotation with a power recovery. The instructor reported the deceleration/flare was executed too low and the tail rotor struck the ground. The helicopter then spun 180 degrees and rolled over onto its left side. A small fire was noted near the engine and the student pilot was pulled from the helicopter by another witness. The helicopter was destroyed by a post-impact fire. 

TYNAN, TX (KIII NEWS) - This is what's left of the crash site here in Tynan after a male pilot crashed his recreational helicopter just before noon Saturday...that pilot somehow surviving, but is now left with serious injuries. 

The helicopter crashed in a field off of County Road 796 near 528 in Bee County. DPS troopers tell us the male pilot, who was the only person in the helicopter at the time of the crash, was unconscious on arrival and suffered head injuries, bruising to the face, and other fractures. He was transported by Halo Flight to Christus Spohn Memorial where he remains in serious condition. Once he was out of the plane, officials tell us it caught fire and charred fragments of it remain here on the scene...a kind of crash law enforcement in our area say rarely happens.

"Fighter planes doing their practicing we've had a couple of those go down in the Live Oak area and of course down in Kleberg County but haven't seen any helicopters crash as of lately," said Sgt. Nathan Brandley with DPS.

Right now the pilot's name and age has not been released or where the helicopter had been flying from. 

Even though most of the wreckage has been removed, the FAA and NTSB are on their way to the scene to investigate how and why the helicopter went down.
