After engine change, major overhaul, or replacement/removal/reinstallation of cylinders or magnetos in a CAP airplane, for how many tachometer hours is it prohibited to carry or tow an aircraft with CAP or ROTC cadets on orientation rides?

After engine change, major overhaul, or replacement/removal/reinstallation of cylinders or magnetos in a CAP airplane, for how many tachometer hours is it prohibited to carry or tow an aircraft with CAP or ROTC cadets on orientation rides?

• A. 5 tachometer hours
• B. 10 tachometer hours
• C. 15 tachometer hours
• D. 20 tachometer hours

Answer: (B)

After engine change, major overhaul, or replacement/removal/reinstallation of cylinders or magnetos in a CAP airplane, there is a safety buffer before carrying cadets on orientation rides. The rule uses tachometer hours, which track the engine’s running time rather than flight time. You must not carry or tow CAP or ROTC cadets on orientation rides until the engine has accumulated ten tachometer hours. This run-in period helps ensure any new or reinstalled components have seated properly and any early issues are identified during controlled testing. To comply, document the maintenance, conduct the required test/run-up flights under supervision, and only then proceed with orientation rides once those ten hours have elapsed.
