How the NTSB plane crash investigation works: What to know
As the investigation into Friday’s fiery and deadly plane crash on Interstate 75 near Naples continues, people throughout Southwest Florida may be wondering what’s happening at the crash site at mile marker 106.8 north of Exit 105 (Golden Gate Parkway).
The southbound lanes of I-75 near the crash site remained closed Sunday as investigators from the National Transportation Safety Board analyzed the site and what remained of the twin-engine Bombardier 600 plane that landed just after 3 p.m. on February 9. The co-pilot was killed. Three people on board the plane survived.
Initially, the southbound lanes were expected to be closed for 24 hours.
What to know: NTSB investigation
According to the NTSB website, “While the precise scope and extent of any specific investigation depends on the nature of the incident being investigated, every NTSB investigation goes through the same general process.”
What is the “process” in an NTSB investigation?
- Initial notification and investigation decision
- Collect facts on site
- Analyze the facts and determine the probable cause
- Acceptance of the final report
- Advocate for acceptance of safety recommendations arising from the investigation
NB: “This process is not strictly linear, and the stages overlap. For example, investigators may wait for log books while they analyze weather information, or their analysis of engine performance data may prompt them to request additional information,” the NTSB says on its website. From the manufacturer.”

How long does the investigation take?
The timing between the start of an investigation, a probable cause determination and a report varies based on the complexity of the investigation and the workload of the agency’s investigators, the NTSB says. Generally, the NTSB attempts to complete an investigation within 12 to 24 months, but these and other factors can significantly affect this timing.
What likely happened at the Naples plane crash site?
- During this phase, NTSB investigators collect the data and information necessary to analyze the accident and determine probable cause. This includes when an NTSB investigator or investigative team – known as the Got Team – travels to the accident site, as well as time spent gathering additional information from outside the accident scene itself, such as flight logs, maintenance logs and personal interviews.
- What’s known as a party system allows the NTSB to designate other organizations or companies as parties to investigations — in the case of the Florida Highway Patrol — and allows the board to leverage its resources to investigate.
Did you know? NTSB Annual Investigations
The NTSB investigates about 1,200 aviation accidents and accidents annually, and about 60 accidents in other modes of transportation: railroads, highways, marine, and pipelines. In some cases, the NTSB decides to hold an investigative hearing to help determine the facts about a transportation accident.
What is the difference between an aviation accident and an accident?
- An aviation accident is defined under the International Civil Aviation Convention, Annex 13, as an event related to the operation of the aircraft, which occurs from the time any person boards the aircraft with Intent to fly Until all of these people disembark, in which case (a) someone is fatally or seriously injured, (b) the aircraft sustains significant damage or structural failure, or (c) the aircraft disappears or becomes completely inaccessible.
- Annex 13 defines an aviation accident as an event, other than an accident, associated with the operation of an aircraft that affects or could affect operating safety.
