NTSB Blames Pilot and Air Traffic Controller for Houston Helicopter Tower Crash That Killed Four

On September 23, 2026, the National Transportation Safety Board published its final report on the night air tour crash that killed four people in Houston in October 2024. The board found that the pilot failed to keep clear of a radio tower, and that the air traffic controller watching her contributed by never issuing a safety alert.

The accident destroyed a Robinson R44 registered N881KE, operated by National Helicopter Solutions on a sightseeing flight under Part 91. The NTSB filed the investigation as CEN25FA019.

Nine minutes from takeoff to impact

The helicopter left Ellington Airport at about 7:42 p.m. local time on October 20, 2024, and flew north, then northwest toward downtown Houston. The pilot called the William P. Hobby Airport control tower and asked for the “downtown loop.” ADS-B data showed the same helicopter had flown that route seven times between October 17 and October 20, five of them at or after sunset.

The controller identified the helicopter on radar, approved the request and passed the altimeter setting. Several minutes later the controller issued a traffic advisory for a second company air tour helicopter.

The pilot replied that she could see the other helicopter on her ADS-B display but had not spotted it visually. She was reading back an instruction to maintain visual separation when her transmission stopped.

The R44 struck a 1,003-foot radio tower about 100 feet below the top. The final ADS-B point was recorded at 7:51:19 p.m., at the tower’s position. The tower collapsed onto the wreckage and a post-impact fire destroyed the helicopter.

The air traffic control operations supervisor saw the crash through the tower window. The pilot, 42, and her three passengers were killed.

Why the controller appears in the probable cause

The NTSB’s probable cause reads: “The pilot’s failure to maintain clearance from a lighted radio tower during a visual night flight. Contributing to the accident was the air traffic controller’s failure to issue a safety alert notifying the pilot of the flight’s unsafe proximity to the tower.”

Naming a controller in the probable cause of a visual-flight-rules accident is notable, because under VFR the pilot is responsible for seeing and avoiding obstacles and a controller is not obliged to navigate for them.

The obligation the board invoked is narrower than that. FAA Order 7110.65, paragraph 2-1-6, requires a controller to issue a safety alert once the controller is aware that an aircraft is at an altitude that, in the controller’s judgment, puts it in unsafe proximity to terrain, obstructions or other aircraft.

Paragraph 2-1-2 ranks that duty first, ahead of everything else a controller is doing. The order concedes a controller “cannot see immediately the development of every situation where a safety alert must be issued,” but requires vigilance for them.

The finding turns on what was on the controller’s screen. The tower was depicted as an obstruction on that radar display and on the charts, and the helicopter tracked straight at it, below its height, for long enough to be seen.

An FAA safety review found traffic volume was light, complexity routine, and no unusual factor that would have distracted the controller. That is what moved the omission from understandable to contributory.

The tower was lit

The detail that dominated coverage in the days after the crash was that the tower’s lights were out. That is not what the investigation found.

The distinction matters because it removes the simplest explanation. A dark obstruction that a pilot could not reasonably have seen is a different accident from a lit one on a charted position.

The board’s findings list an environmental factor as contributing, alongside the pilot’s identification and recognition and the lack of communication from air traffic control. Beacons on a tower compete with the city skyline behind them, which is a recognition problem rather than a lighting failure.

A pilot four weeks into flying the company’s helicopters

The pilot held commercial and flight instructor certificates with helicopter and instrument ratings, and had logged 1,075 total flight hours. She was hired in August 2024 and first flew a company helicopter on September 23, 2024, about four weeks before the accident.

Another company pilot trained her on the tour routes, including operating near high-rise buildings and a 700-foot lighted pole by the Houston aquarium. The operator had no documented training program and, under Part 91, was not required to have one.

The NTSB recorded that the company never handed over the pilot records it said it held, despite repeated requests, so investigators rebuilt her flying history from interviews. Her husband told them she had worked about nine days in a row.

The Robinson R44 was built in 2002 and had 4,676.7 airframe hours at its last inspection, 13 days before the crash.

Rather than issue new recommendations, the report points back to AAR-21/03, the study the NTSB adopted in March 2021 on revenue passenger flights run under Part 91. That report sent the FAA six new safety recommendations and reiterated four more.

The board restates the gap it identified then. A Part 91.147 air tour operator is not subject to oversight comparable to Part 135, including a safety management system, and the letter of authorisation process collects no pilot qualification information and requires no checkrides.
