Flight crew: Instrument proficiency check requirements

This regulation establishes instrument proficiency check requirements for pilots operating under fractional ownership programs (Part 91 Subpart K).

Pilot-in-command must complete an instrument proficiency check every 6 calendar months, while second-in-command pilots need one every 12 months. These checks must be administered by the FAA or an authorized check pilot.

The check includes an equipment test (oral or written) covering aircraft systems and emergencies, plus a flight check demonstrating instrument navigation, emergency procedures, and approach procedures. Within the preceding 6 months, pilots must also demonstrate specific approach types: precision approaches require demonstrating that specific procedure, while nonprecision approaches require demonstrating either that procedure or any two different nonprecision procedures. All demonstrations must include at least one straight-in, one circling approach, and one missed approach to published minimums.

Pilots assigned to multiple aircraft types must rotate checks among those types. Those flying both single and multi-engine aircraft must alternate between them, starting with multi-engine. Simulators may be used if approved.
