Timeline of the February 9, 2024, N823KD Accident

On February 9, 2024, while operating a flight from Ohio State University Airport (KOSU) in Columbus, Ohio, to Naples Municipal Airport (KAPF) in Southwest Florida, N823KD departed at approximately 1517 Eastern Standard Time. The charter flight, operated as Hop-A-Jet Flight 823, was carrying two pilots—Captain Edward Murphy (50) and First Officer Ian Hofmann (65)—along with two passengers and one flight attendant.

Shortly before landing, Hop-A-Jet Flight 823 experienced a dual engine failure during final approach to Naples Airport, around mid-afternoon. The crew configured the aircraft for landing with gear and flaps extended. At roughly 1,800 feet above ground level and approximately two miles from the runway, both engines lost thrust. The crew immediately declared an emergency to air traffic control.

Critical Sequence

• Within approximately 60 seconds, the aircraft lost over 50 knots of airspeed

• Altitude dropped more than 1,000 feet

• High-drag configuration severely limited the glide distance

• Pilots selected Interstate 75 southbound as the emergency landing site

The jet crashed on Interstate 75 in Naples, Florida, colliding with vehicles, breaking apart, and being consumed by post-crash fire. The incident resulted in the fatalities of both pilots, while one flight attendant and two passengers survived with minor injuries. No ground fatalities were reported.

Flight Data, Investigation, and NTSB Findings

The National Transportation Safety Board launched a full investigation immediately after the accident, supported by the FAA, GE Aerospace, Bombardier, and Transport Canada. The NTSB investigates aviation accidents to assess factors such as flight data, maintenance records, and crew qualifications, which are critical for understanding safety issues and the aircraft's operation. Establishing strong relationships with regulatory bodies like the FAA and NTSB is vital for effective crisis management, as it allows for better cooperation and support during investigations following an accident.

Investigators recovered the flight data recorder (FDR) and cockpit voice recorder (CVR) from the wreckage. The I-75 southbound lanes remained closed for documentation and debris recovery, reopening by February 11, 2024. Recorders were analyzed at NTSB headquarters in Washington, D.C.

Central Technical Finding:

The investigation determined that a non-recoverable dual-rotor compressor stall occurred in both CF34-3B engines. This failure was linked to severe internal corrosion and binding in the variable guide vane (VGV) system, which prevented proper adjustment during the power increase demanded on approach. The NTSB reported that the crew received oil pressure warnings shortly before the engine failures, highlighting the importance of monitoring operational data and adhering to safety procedures.

The data revealed that thrust loss happened precisely as pilots configured for landing. With gear and flaps deployed, the aircraft’s drag increased significantly while available power dropped to zero. Despite crew efforts, neither engine recovered thrust.

The report focused on technical facts rather than apportioning legal blame, emphasizing lessons for regulators and operators industry-wide.

Maintenance History and Engine Corrosion Issues

The investigation examined N823KD’s maintenance records, uncovering gaps that obscured a progressive corrosion trend in the CF34-3B engines. Operational reliability and safety management are critical in ongoing maintenance and inspection routines, ensuring that every aspect of the aircraft's operation is thoroughly monitored to maintain safe and efficient performance.

January 2024 Events

Approximately two weeks before the accident, the aircraft experienced dual “hung-start” issues—incomplete engine spool-up during startup. Maintenance actions included:

• Air filter replacements

• Engine restarts with GE input

• Return to service for multiple flights

However, technicians did not perform deeper borescope inspections, such as Maintenance Practice 68 Step 22.

Earlier Inspection Gaps

Date	Inspection Type	Finding	Documentation
March 2019	3,200-hour borescope	Corrosion near the VGV bushing bore holes	Inadequately logged
November 2020	192-month inspection	Compressor case corrosion	Not fully recorded

These documentation deficiencies made it difficult for later technicians to determine the scope of corrosion progression. The gaps represent a systemic issue in tracking VGV-related risks on aging CF34-3B engines.

Other CF34 Engine Events and Regulatory Response

The CF34 engine family powers thousands of business jets and regional airliners. Prior incidents had already triggered regulatory action before the N823KD accident.

In 2021, GE Aerospace issued a Category 1 Service Bulletin addressing VGV and compressor issues on certain CF34 models following a regional jet incident. The FAA subsequently issued an Emergency Airworthiness Directive (AD) for CF34-8 variants on Part 121 airliners.

However, this directive did not apply to CF34-3B engines on Part 135 business jets like the Challenger 604—creating a regulatory gap.

After the N823KD crash:

• Operators revisited inspection requirements for CF34-3B engines

• Industry discussions intensified on aligning Part 135 maintenance with airliner standards

• Legal actions filed in 2025 sought damages and pushed for updated service bulletins

The incident highlighted the difference between commercial airline oversight and business aviation maintenance requirements, which becomes apparent when reviewing the broader landscape of charter airlines and private flight options.

Human Factors, Crew Actions, and Industry Lessons

The flight crew demonstrated professional skill under catastrophic circumstances. Both pilots lost their lives while working to save their passengers and protect people on the ground. In the event of a dual engine failure, pilots face significant challenges, including increased drag from deployed flaps and landing gear, which complicates their ability to glide to a safe landing area.

Available data shows the crew:

• Declared an emergency promptly and communicated clearly with air traffic control

• Fought to maintain airspeed despite rapidly decaying thrust

• Selected the I-75 highway landing to avoid populated areas

• Prioritized survivable impact geometry over personal safety

The flight attendant played a critical role in evacuating survivors after the impact. Industry organizations, including the National Business Aviation Association, later recognized these life-saving actions.

Emergency preparedness in aviation involves routine training for scenarios that are unlikely to occur, ensuring crews are ready to respond effectively if emergencies do arise.

Industry-Wide Lessons

• Enhanced simulator training for engine-out scenarios and consideration of crowdsourced private jet flights and shared empty seats to make safety-focused private travel more cost-effective

• Updated emergency checklists for highway landing decisions

• Improved operator-manufacturer communication on maintenance trends

• Support systems to assist crew and families affected by aviation accidents

• Training for emergency scenarios is essential, and companies must have a plan and regularly assess risks

• Following an aviation accident, it is essential for companies to activate their emergency response plans (ERPs) to manage the situation effectively and assist those affected

The accident remains a case study in how crew training and decision-making can determine outcomes even in non-survivable situations.
