One more time for clarification Andy. This from the CAMI report itself:

The first issue confronted was the definition of the population to be studied. For example, the Senate directive requested a comparison of accident rates by age for "nonscheduled commercial" and "scheduled commercial" pilots. "Non-commercial" pilots were to be included as available. This implied defining the pilot population in terms of types of operation (scheduled versus unscheduled) and employer (commercial and noncommercial). However, the data required to segment the pilot population along these lines are not available from FAA pilot records. The available FAA data source is the
Comprehensive Airman Information System (CAIS), which describes (a) the type(s) of certificate(s) issued to a pilot, (b) aircraft type ratings for a pilot, (c) class of medical certificate issued, (d) self-reported employer, and (e) self-reported hours flown. The Pilot Age & Accident Rates Report
official system of FAA records does not capture the types of operation (scheduled or unscheduled, commercial or non-commercial) in which a pilot has engaged. Given the limits of available data, therefore, the definition of the population of pilots to be studied had to be based on the type of certificates held by a pilot. One definition of the population likely to be included in the phrasing "non-scheduled commercial (and noncommercial, if available)" and "scheduled commercial pilots (and non-commercial pilots, if available)," based on available data, was pilots holding Class 1 medical and air transport pilot (ATP) certificates. Pilots holding these certificates can conduct scheduled and non-scheduled flights for air carriers and commercial operators under 14 CFR §121 and §135. Depending on the employer, they may also engage in commercial or noncommercial operations.

Essentially your assertion that the study is for 121 pilots only is an exaggeration. As you can plainly see it also includes 135. That could be scheduled or it could be on-demand charter. I would be fairly certain that is where the majority of the accidents are from so this whole study is somewhat flawed for use when talking about Air Carrier Operations.

Please try again.
