This article is based on an official preliminary report from the National Transportation Safety Board (NTSB) and local reporting.

NTSB Issues Preliminary Report on Fatal Sonex Onex Crash in Caldwell, Idaho

The National Transportation Safety Board (NTSB) has released its preliminary report regarding the fatal aviation accident that occurred on February 6, 2026, in Caldwell, Idaho. The investigation focuses on the crash of a Sonex Aircraft Onex, an experimental amateur-built plane, which resulted in the death of the pilot shortly after takeoff from Caldwell Executive Airport (KEUL).

While initial data streams may have misidentified the location as Caldwell, Texas, the NTSB and local authorities have confirmed the incident took place in Idaho. The preliminary document outlines the factual sequence of events known to investigators at this stage, though a determination of probable cause remains pending as the inquiry proceeds.

According to the NTSB, the accident occurred at approximately 11:30 AM MST under Visual Meteorological Conditions (VMC). The release of this report marks the first official federal documentation of the tragedy, providing a baseline for the ongoing safety investigation led by federal authorities with support from the Federal Aviation Administration (FAA).

Flight Sequence and Crash Details

The preliminary findings indicate that the aircraft, identified by registration number N362DZ, departed from Caldwell Executive Airport late in the morning. Witnesses and local authorities reported that the flight was brief. Shortly after lifting off, the single-seat aircraft descended and impacted the ground near the intersection of Ustick Road and Aviation Way, just outside the airport’s perimeter.

The NTSB report notes that the aircraft sustained “substantial damage” upon impact. Following the crash, the airframe was consumed by a post-impact fire. Emergency response teams from the Caldwell Fire Department arrived on the scene shortly before 11:30 AM to manage the blaze, but the pilot had already succumbed to the crash trauma.

Local officials, including the Canyon County Coroner, identified the pilot as 79-year-old Bayne Just, a resident of Nampa, Idaho. He was the sole occupant of the aircraft. Authorities confirmed there were no injuries to persons on the ground.

Investigation Status and Aircraft Background

Preliminary Findings

As is standard for NTSB investigations, the preliminary report does not speculate on the cause of the accident. Instead, it catalogues the immediate environmental conditions and the state of the wreckage. Investigators noted that weather conditions were clear at the time of the flight, suggesting that adverse weather was likely not a primary factor. The investigation is currently examining the wreckage, pilot records, and aircraft maintenance history to determine if mechanical failure or pilot error played a role.

The Sonex Onex Platform

The aircraft involved was a Sonex Aircraft Onex (pronounced “One-Ex”). This model is a popular experimental, amateur-built kit plane designed for a single pilot. It is well-regarded in the aviation community for its compact size and folding wings, which allow it to be stored in a standard garage. These aircraft are typically powered by Volkswagen-derived AeroVee engines or similar powerplants.

Because the aircraft operates under an experimental airworthiness certificate, the builder, often the owner, is responsible for the construction and maintenance of the vehicle. The NTSB investigation will likely review the build logs and maintenance records of N362DZ as part of the factual report phase.

AirPro News Analysis

The release of a preliminary report typically occurs 10 to 14 days after an aviation accident. It serves to inform the public and the aviation industry of the basic facts while the detailed investigation continues. For the general public, it is important to distinguish between this preliminary document and the final report.

The “probable cause” of the accident will not be determined until the final report is issued, a process that generally takes between 12 and 24 months. During this interim period, the NTSB may release a “Factual Report” containing detailed engineering and medical data. Given the experimental nature of the aircraft, investigators will pay close attention to the engine’s performance and the flight control systems, as these are critical variables in amateur-built aviation accidents.

We advise caution against speculation regarding the cause of the crash until the NTSB completes its rigorous analysis of the recovered airframe and engine components.

Cessna 172S Crashes in Pacoima Near Whiteman Airport

A Cessna 172S crashed upside-down in Pacoima, CA, causing power outages and evacuations. Pilot hospitalized; FAA and NTSB investigating.

Published

on

This article summarizes reporting by NBC Los Angeles and Jonathan Lloyd, supplemented by comprehensive incident research data.

A small single-engine airplane crashed upside-down into a commercial auto parts store parking lot in Pacoima, California, on Monday morning. The incident downed high-voltage power lines and prompted immediate emergency responses, though it miraculously spared bystanders and parked vehicles.

The crash occurred just blocks from Whiteman Airport, a general aviation facility that has been the subject of intense community scrutiny following a series of aviation accidents in recent years. The sole occupant of the aircraft, a 70-year-old male pilot, survived the impact and was hospitalized.

According to initial reporting by NBC Los Angeles, the Los Angeles Fire Department (LAFD) responded to the downed plane near the intersection of Ralston Avenue and Van Nuys Boulevard, where they encountered significant electrical hazards caused by the damaged infrastructure.

Details of the Pacoima Crash and Emergency Response

The Aircraft and the Pilot

Incident research reports identify the aircraft as a 2007 Cessna 172S Skyhawk, which is reportedly registered to a local flight school. The crash was reported to authorities at approximately 11:08 a.m. local time on Monday, April 20, 2026. The plane came to rest inverted in the parking lot of an O’Reilly Auto Parts store located on the 10800 block of N. San Fernando Road, sustaining heavy damage to its nose.

First responders from the LAFD and the Los Angeles Police Department (LAPD) arrived swiftly to find the 70-year-old pilot trapped inside the wreckage. Crews successfully extricated the man, who was able to speak with responders at the scene. He was transported to a local hospital and is reported to be in critical but stable condition.

Public Safety Measures

NBC Los Angeles reported that high-voltage power lines were damaged during the incident. Research data confirms that the aircraft snapped a power pole upon descent. Due to the severe electrical hazard, police and fire crews shut down Van Nuys Boulevard from Ralston Avenue to San Fernando Road.

Authorities also initiated temporary evacuations of nearby businesses and residences as a safety precaution while utility crews worked to neutralize the downed lines. Fortunately, the aircraft did not strike any bystanders or parked cars during its descent.

The Shadow of Whiteman Airport

A History of Aviation Incidents

This latest crash contextualizes ongoing safety concerns regarding Whiteman Airport (WHP), located just a short distance from the crash site. The airport caters to general aviation, hobbyists, and flight schools, but its placement within a densely populated San Fernando Valley neighborhood has made it a flashpoint for controversy.

Over the past decade, the area has seen over a dozen crashes associated with the airport. Historical incident data highlights several severe accidents, including a fatal November 2020 crash of a Cessna 182 into a residential street, a dramatic January 2022 incident where a Cessna 172 lost power and was struck by a Metrolink train, and a fatal April 2022 crash of a Cessna Skymaster near the 210 Freeway.

Political and Community Pushback

Following previous crashes, local residents and community advocacy groups, such as Pacoima Beautiful, have mounted heavy pressure to close the 1940s-era airport. Elected officials, including U.S. Representative Tony Cárdenas and L.A. City Councilmember Monica Rodriguez, have been vocal critics of the facility’s safety record.

“The surrounding community is literally afraid for their lives. There are way too many crashes coming in and out of Whiteman Airport.”
, U.S. Representative Tony Cárdenas, in previous public statements regarding the airport.

The Los Angeles County Board of Supervisors previously approved a $1.9 million study to explore alternative land uses for the 184-acre airport property. However, aviation advocates maintain that the airport provides local jobs, serves as a crucial emergency hub, and is protected by federal grant obligations.

Looking Ahead: Investigations and Airport Future

AirPro News analysis

We anticipate that the Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) will lead the official investigation into Monday’s crash to determine the exact cause. Given that the Cessna is reportedly registered to a local flight school, investigators will likely scrutinize the school’s maintenance protocols, aircraft logs, and the pilot’s training records.

Furthermore, this highly visible incident, where an airplane fell into a commercial parking lot on a Monday morning, will almost certainly accelerate political momentum against Whiteman Airport. Because the crash resulted in downed high-voltage lines and evacuations, it serves as a stark reminder of the inherent risks of operating a general aviation hub in a densely populated urban zone. We expect renewed legislative efforts and heightened community mobilization regarding the future of the 184-acre site in the coming weeks.

Frequently Asked Questions (FAQ)

  • Were there any casualties on the ground? No. Miraculously, no bystanders were injured, and no vehicles were struck when the plane crashed into the parking lot.
  • What is the condition of the pilot? The sole occupant, a 70-year-old man, was extricated by first responders and is currently in critical but stable condition.
  • What caused the plane to crash? The official cause of the crash is currently unknown. The FAA and NTSB typically lead investigations into such aviation incidents.
  • Did the crash cause power outages? The aircraft snapped a power pole and downed high-voltage power lines, prompting street closures and temporary evacuations while utility crews neutralized the hazard.

Airborne Aviation Helicopter Crash Off Kauai Hawaii Investigated

NTSB reports a Hughes 369D helicopter crash off Kauai, Hawaii, with 3 fatalities and mechanical failure suspected in a sightseeing flight.

Published

on

This article is based on an official preliminary report from the National Transportation Safety Board (NTSB), supplemented by AirPro News research.

On March 26, 2026, a Hughes 369D sightseeing Helicopters operated by Airborne Aviation crashed into the ocean off the Na Pali Coast of Kauai, Hawaii. The accident, which occurred at approximately 3:39 p.m. Hawaii Standard Time (HST), resulted in three passenger fatalities and serious injuries to the pilot and one surviving passenger. The aircraft was conducting a Title 14 Code of Federal Regulations Part 135 revenue sightseeing flight.

The National Transportation Safety Board (NTSB) has released its preliminary report detailing the sequence of events. The findings point to a sudden in-flight emergency characterized by severe vibrations and a loss of directional control, prompting an emergency autorotation into the water.

As federal investigators continue to examine the recovered wreckage, the crash brings renewed attention to the Safety of air tour operations in Hawaii. The incident raises specific questions concerning “doors-off” flight profiles, over-water equipment regulations, and the mechanical reliability of aging sightseeing fleets.

Sequence of the Fatal Flight

Departure and In-Flight Emergency

According to the NTSB preliminary report, the helicopter, bearing tail number N715KV, departed Lihue Airport (LIH) at approximately 3:12 p.m. HST. It was scheduled for a local sightseeing tour, marking its sixth and final flight of the day. The flight proceeded uneventfully until it reached the northern shore of the island near Haena, roughly 20 miles northeast of the airport.

The pilot told investigators that upon reaching Kalalau Beach, he initiated a standard left turn away from the shoreline. It was during this maneuver that the aircraft experienced a severe mechanical anomaly.

“Upon entering the turn, the pilot experienced a high frequency vibration throughout the helicopter that came in waves and became stronger each time.”

, NTSB Preliminary Report

Loss of Control and Water Impact

Following the onset of the vibrations, the helicopter began an un-commanded right yaw. The NTSB notes that the pilot attempted to correct the spin using the left anti-torque pedal, but the input was ineffective. The aircraft quickly rotated clockwise, completing approximately two full rotations.

In response, the pilot entered an autorotation, rolling the throttle to idle to stop the spinning and attempting to increase airspeed for better directional control. He subsequently broadcasted a Mayday radio call. Unable to glide to the beach, the helicopter nosedived and impacted the water roughly 75 to 100 yards from the shoreline. The aircraft rolled onto its right side and became partially submerged.

Witness accounts detailed in the NTSB report corroborate the sequence. One witness flying nearby observed the helicopter impact the water and come to rest upright, tilted slightly to the right. The surviving passenger reported hearing a distinct change in the aircraft’s sound before it slowed down, rotated, and nosedived into the ocean.

Aircraft, Operator, and Rescue Efforts

Airborne Aviation and the Hughes 369D

The aircraft involved was a 1979 Hughes 369D, commonly referred to as an MD 500D, equipped with a Rolls-Royce M250 series engine. Federal Aviation Administration (FAA) records indicate the helicopter was registered to AA Leasing LP in Kilauea, Kauai. AirPro News research confirms the aircraft previously operated in Canada, where it was equipped with flotation tanks for water landings. However, it was operating its Hawaii tours without this over-water setup.

The operator, Airborne Aviation, is a Lihue-based company known for offering “doors-off” adventure tours. Following the accident, the company suspended all tour operations. Local authorities identified the three deceased passengers as Margaret Rimmler, 65; Patrick Haskell, 59; and Oksana Pihol, 40.

Emergency Response

The remote location of Kalalau Beach necessitated a rapid and complex rescue operation. According to local emergency response data, campers and Good Samaritans on the beach immediately swam out to the sinking wreckage to pull the five occupants from the water and administer aid.

A large-scale official response followed, involving the Hanalei Fire Station, the Kauai Fire Department, the U.S. Coast Guard, and the Department of Land and Natural Resources (DLNR). The two survivors were medically evacuated to Wilcox Medical Center in Lihue for treatment of serious injuries.

Investigation and Broader Context

Flight Data and Weather Conditions

The NTSB has recovered the helicopter’s fuselage and main rotor blades, which sustained substantial damage, to a secure facility for further examination. Alongside the physical wreckage, investigators will likely scrutinize flight tracking data.

Public ADS-B flight data analyzed in AirPro News research revealed unusual speed fluctuations during the fatal flight. At 3:30 p.m., the helicopter’s speed abruptly dropped from 110 knots to 30 knots at an altitude of 3,500 feet before recovering. Similar sharp slowdowns were recorded on the helicopter’s previous flights that day. Additionally, an AIRMET Tango advisory for aviation turbulence was active across the Hawaiian islands at the time of the crash.

AirPro News analysis

While weather has historically played a significant role in Hawaiian air tour accidents—such as the December 2019 Safari Helicopters crash that killed seven people in low-visibility conditions—the circumstances of the Airborne Aviation crash point strongly toward a catastrophic mechanical failure. The pilot’s description of wave-like, high-frequency vibrations and a total loss of anti-torque control is highly indicative of a failure within the tail rotor drive system.

Furthermore, this incident highlights ongoing regulatory tensions regarding over-water helicopter operations. The fact that this single-engine aircraft was conducting “doors-off” flights over the ocean without emergency pop-out floats exposes a persistent loophole in safety mandates. Despite the FAA implementing a new authorization process in 2023 for Hawaii air tour operators, the industry continues to balance the economic demands of tourism against the inherent risks of low-altitude flying over rugged, maritime terrain.

Frequently Asked Questions

What caused the Airborne Aviation helicopter crash?

The exact cause is currently under Investigation by the NTSB. However, preliminary reports indicate the pilot experienced severe vibrations and a loss of tail rotor effectiveness, suggesting a mechanical failure rather than a weather-related event.

What type of helicopter was involved?

The aircraft was a Hughes 369D, often referred to as an MD 500D, manufactured in 1979. It was operating a “doors-off” sightseeing tour at the time of the Accident.

Were there any survivors?

Yes. The pilot and one female passenger survived the crash with serious injuries and were medically evacuated to a local hospital. Three other passengers were fatally injured.
