Accident Details

On November 11, 2017, about 1300 mountain standard time, a Robinson R44 helicopter, registration N744BS, impacted terrain during takeoff from Page Municipal Airport (PGA), Page, Arizona. The commercial pilot and passenger sustained minor injuries; the helicopter sustained substantial damage. The helicopter was registered to R44 White LLC and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originally departed about 1245.

Pilot and Passenger Accounts

The pilot reported the purpose of the flight was to practice in the traffic pattern, landings, and hovers. After a normal traffic pattern and landing, he hovered the helicopter. While the helicopter was transitioning from hover to forward flight, the nose suddenly pitched down steeper than the pilot expected. The pilot immediately applied aft cyclic, however, he was unable to recover. The helicopter impacted the ground and came to rest on its side.

The passenger reported that the helicopter started to lift off; when it was about one foot above the ground, the helicopter started leaning forward and it continued forward until the skids, then rotor blades, touched the ground.

Postaccident Examination

During a postaccident examination of the helicopter, the collective, cyclic, and left anti-torque pedal were manipulated within the cockpit and corresponding motion was observed at the appropriate flight controls. The right anti-torque pedal moved freely from both within the cockpit and from the tailboom; however, no corresponding motion was observed. Visual examination revealed the control tube was fracture separated underneath the heavily damaged floorboard.

Operator Information

The operator reported that, on the morning of the accident, the owner of the helicopter flew about two hours with the pilot to orient him in the make/model helicopter involved in the accident.
