US-FAA14 CFR 135.339

Initial and transition training and checking: Check pilots

Read the official rule

This regulation sets the training and currency requirements for check pilots who evaluate other pilots in Part 135 operations.

To serve as a check pilot, a person must complete initial or transition check pilot training and, within the preceding 24 months, successfully conduct an observed proficiency or competency check watched by an FAA inspector or company-designated examiner. This observation can occur in an aircraft, simulator, or training device, and is considered current if completed within the month before or after it's due.

Initial ground training covers check pilot duties, applicable regulations and company procedures, evaluation techniques, detecting inadequate training or unsafe personal characteristics, corrective actions, and aircraft procedures. Transition training focuses on procedures specific to the new aircraft type.

Flight training teaches check pilots how to conduct evaluations safely from either pilot seat (or observation seat in powered-lift aircraft), handle emergency situations during checks, and for simulator check pilots, operate training devices effectively. This training may be completed in actual flight or approved simulators.
