In its 2024 report, Safety and Industry Data Improvements for Part 135 Operations, the NTSB examined 116 fatal and 460 nonfatal accidents from 2010 through 2022. It reported that Part 135 accident rates had historically exceeded Part 121 rates. It also identified gaps in the data needed to compare different kinds of Part 135 flying.
That matters because on-demand operations include very different missions. A broad charter category is not a clean measurement of professionally operated business jets alone. The report makes a case for stronger risk management and better evidence, not for a blanket “safest” claim.
A newer, independently authored study offers another useful perspective. Janeen Adrion Kochan, Stuart “Kipp” Lau and Paul “BJ” Ransbury’s October 2026 U.S. NTSB Accident Data 2016–2025 analysis estimated the following fixed-wing accident rates using NTSB records and FAA activity data.
Operating categories in one study
U.S. fixed-wing operations, 2016–2025 · estimated rates
Executive/corporate, paid crews
0.17 accidents / 100,000 flight hours
0.83 accidents / 100,000 flight hours
General aviation business, without paid crews
1.33 accidents / 100,000 flight hours
Source: Kochan, Lau & Ransbury, October 2026, Table 13. Categories are not private-jet-only and are not directly comparable with passenger-airline odds.
These are estimated accidents per 100,000 flight hours, not passenger fatality odds. The study was sponsored by upset-training company APS, was independently authored and was not an NTSB report or endorsement. Its category mapping involves assumptions; 2025 flight hours were extrapolated from the 2022–2024 average. These categories include more than jets, and their missions differ.
The paid-crew category’s lower estimate is encouraging, but does not prove that crews alone caused the difference or that private flying beats airlines. Our conclusion is narrower: the operating model deserves as much attention as the aircraft.
Airline statistics cannot fill that gap. Barnett and Reig Torra’s peer-reviewed 2024 study, Airline safety: Still getting better?, concerns scheduled passenger airlines. Its widely reported safety figures should not be presented as private-jet odds.
