Fatal Arizona Helicopter Crash: Was the NOTAM System Warning Missed?

The NTSB is probing a fatal MD Helicopters 369FF crash in Arizona that killed four after hitting a slackline, raising questions about the FAA's NOTAM alert system.

Key Points

1Four people died on January 2, 2026, when an MD Helicopters 369FF struck a slackline in a remote Arizona canyon.
2A Notice to Air Missions (NOTAM) was issued for the obstruction but was linked to a nearby airport, not the helicopter's departure airport.
3The NTSB is investigating the NOTAM distribution process and pilot pre-flight briefing procedures, with a preliminary report expected within 30 days.
4The incident highlights the critical and ongoing challenge of mitigating wire strike risks for low-altitude helicopter operations.

A fatal aviation incident in Arizona has put the spotlight on the Notice to Air Missions (NOTAM) system.

A helicopter crash near Superior, Arizona, killed all four people on board. Initial findings suggest the aircraft struck a high-tension slackline. The crash has prompted a comprehensive investigation by the NTSB.

The Arizona Incident

The accident occurred on January 2, 2026, in a remote canyon area. The helicopter was an MD Helicopters 369FF model. Pilot David McCarty and three passengers were killed. The passengers were identified as his nieces. The aircraft had departed from Pegasus Airpark (5AZ3) in Queen Creek.

An eyewitness reported seeing the helicopter strike a portion of the line. The slackline was reportedly more than a half-mile long. It was stretched across Telegraph Canyon. The line was approximately 600 feet above ground level.

The NOTAM System Controversy

Federal aviation records confirm a NOTAM was issued before the crash. The notice warned pilots about the temporary obstruction. It was in effect from late December 2025 through early January 2026. The International Slackline Association confirmed the line was marked. They also noted the FAA was informed and a NOTAM was issued.

Key Details of the Alert

The core of the investigation centers on the NOTAM's distribution. The alert was linked to the Superior Municipal Airport (E81). This airport is near the crash site. However, it was not the helicopter's departure airport.

Experts suggest the pilot may not have seen the NOTAM. Pilots check notices along their flight path. They also check notices within a 25-nautical-mile radius. The NTSB is examining the entire process. They will determine if the slackline was properly authorized.

Industry Implications and Safety Focus

This tragic event highlights the perpetual risk of wire strikes for helicopter operations. Power lines and unmarked cables are difficult to see. This is especially true without poles or markers. The incident is considered unique in aviation history. Safety experts are unaware of other slackline-related helicopter crashes.

The incident also renews focus on the NOTAM system itself. The FAA has been working to update the system. The NTSB investigation will likely result in safety recommendations. These findings could impact pre-flight briefing requirements. They will also affect how temporary obstructions are filed. A preliminary report is expected within 30 days of the accident. The final determination of probable cause may take 12 to 24 months. For more commercial aviation news and updates, visit the flying.flights website.

Helicopter pilots are trained to look for wires. They are constantly looking for pylons and towers. The incident is a stark reminder that aviation is unforgiving. All pilots must be vigilant during flight planning.
