Which of the following is considered allowable personnel on Part 91 flights?

• A. PIC & SIC
• B. Company Technician
• C. Non-company technician w/ OCC authorization
• D. All of the above

Answer: (D)

Part 91 operations allow the presence of personnel beyond just the flight crew when it serves the safety and operation of the flight, as long as proper authorization and qualifications are in place. The pilot in command (PIC) and the second in command (SIC) are the essential flight crew, but a company technician can accompany the aircraft to assist with maintenance or troubleshooting as needed and with the operator’s approval. A non‑company technician may also be aboard if the Operations Control Center (OCC) authorizes them to perform necessary tasks. When these conditions are met, all of these scenarios are permissible, so “All of the above” is correct.
