Investigation Docket - National Transportation Safety Board:
Location: Ithaca, Nebraska
Accident Number: CEN22LA345
Date and Time: July 28, 2022, 12:15 Local
Registration: N719TF
Aircraft: ROBINSON HELICOPTER COMPANY R44 II
Aircraft Damage: Substantial
Defining Event: Collision with terr/obj (non-CFIT)
Injuries: 1 None
Flight Conducted Under: Part 137: Agricultural
Analysis
The pilot was enroute to the next field he would spray and used a handheld GPS unit to navigate. When he finished imputing information into the GPS, he looked up and saw power lines across his flight path. The pilot pulled up on the collective and cyclic to climb; however, the helicopter struck the upper power line. The pilot entered an autorotation, during which the pilot felt unusual vibrations, but had full authority of the flight controls. The helicopter settled into a mature stand of corn, which resulted in structural damage to the tail boom and main rotor system. The pilot stated that he should have climbed to 500 ft agl before he used his GPS to navigate to the next field.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s failure to maintain clearance from power lines during low level aerial application operations due to a distraction.
Findings
Personnel issues (general) - Pilot
Personnel issues Monitoring environment - Pilot
Aircraft Altitude - Not attained/maintained
Environmental issues Wire - Awareness of condition

Preventing Similar Accidents
Preventing Obstacle Collisions in Agricultural Operations
Accidents involving collisions with obstacles, including poles, wires, guy wires, meteorological evaluation towers (MET), or trees, are among the most common types of agricultural aircraft accidents. Some collisions involved obstacles that the pilots did not see (even during survey flights) but others involved obstacles that were known to the pilot and/or had characteristics that would make them visibly conspicuous.
Agricultural pilots should do the following:
Maintain a quick-reference document (paper or electronic) at the operations base that contains field maps, charts, photographs, and details of all known obstacles.
Frequently review current aeronautical charts for information about obstacles.
Before leaving the ground, spend time becoming familiar with all available information about the target field and programming navigation equipment. Such preflight action can help reduce the potential for confusion or distraction in flight.
Conduct aerial surveys of the target field but do not rely solely on an aerial survey to identify potential obstacles.
Conduct regular ground surveys of fields. Some towers can be erected in hours, and obstacles can change since you last worked that field. Speak with farmers and land owners to raise awareness about obstacle hazards.
When possible, use ground crews. They may be in a better position to see certain obstacles and help you ensure that your aircraft remains clear of them.
Watch for shadows and irregularities in growth patterns to help identify obstacles. Use GPS and other technology to maintain awareness of obstacle locations.
Be aware that workload, fatigue, sun glare, and distractions in the cockpit can adversely affect your ability to see, avoid, or remember obstacles. Heavier loads and higher density altitudes can affect the performance of your aircraft.
The National Agricultural Aviation Association's Professional Aerial Applicators' Support System reminds pilots that, when ferrying an aircraft or transitioning between sites, flying above 500 feet reduces obstacle collision risks: "Ferry Above Five and Stay Alive."
