On February 9, 2024, about 1511 eastern standard time, a Bombardier CL-600-2B16 airplane,
N823KD, was destroyed when it was involved in an accident near Naples, Florida. The two
airline transport pilots were fatally injured. The cabin attendant and the two passengers
sustained minor injuries, and one person on the ground suffered a minor injury. The airplane
was operated by Ace Aviation Services (doing business as Hop-A-Jet) as a Title 14 Code of
Federal Regulations Part 135 on-demand passenger flight.
The airplane was returning to Naples Municipal Airport (APF), Naples, Florida, from Ohio State
University Airport (OSU), Columbus, Ohio, where it had flown earlier in the day. The airplane
was serviced with 350 gallons of fuel before departure from OSU.
ADS-B flight track data and downloaded cockpit voice recorder (CVR) communications
revealed that the flight crew contacted the APF air traffic control tower while on a right
downwind leg of the approach to the airport and maneuvering for a 5-mile final approach to
runway 23. About 1509, the tower controller cleared the flight to land. The airplane was about
6.5 miles north of APF, about 2,000 ft geometric altitude, and 166 kts ground speed, as it
turned onto final approach for runway 23.
Review of the data recovered from the airplane’s flight data recorder revealed that the first of
three master warnings was recorded at 1509:33 (L ENGINE OIL PRESSURE), with the second
immediately following at 1509:34 (R ENGINE OIL PRESSURE), and the third at 1509:40
(ENGINE). These warnings were annunciated by illumination of a “Master Warning” light on the
glareshield, a corresponding red message on the EICAS, and a triple-chime voice advisory
(“Engine oil”).
Twenty-three seconds later, at 1510:03, about 1,000 ft pressure altitude and 122 kts, on a
shallow intercept angle for the final approach course, the crew announced, “…lost both
engines… emergency… making an emergency landing” (see figure 1). The tower controller
acknowledged the transmission and cleared the airplane to land. At 1510:12, about 900 ft and
115 kts, the crew replied, “eh we’re clear to land but we’re not gonna make the runway uh we’ve
lost both engines.”
