Who can conduct a Group 2 In-Flight Functional Check?

• A. Maintenance Staff
• B. Chief Pilot
• C. A Line Check Airman
• D. Any Flight Crew

Answer: (C)

A Group 2 In-Flight Functional Check is an in-flight evaluation done after maintenance to verify that aircraft systems operate correctly before the aircraft returns to service. This check must be performed by someone who is specifically designated and trained to conduct line checks on that aircraft, with the authority to evaluate performance and sign off the airworthiness.

A Line Check Airman is the person who holds that designation. They are authorized and qualified to perform line checks, including in-flight functional evaluations, ensuring the aircraft meets required standards after maintenance. This makes them the appropriate choice for conducting a Group 2 In-Flight Functional Check.

Maintenance staff handle the actual repairs and servicing but are not authorized to certify the aircraft as airworthy post-maintenance. The Chief Pilot oversees operations but does not typically perform this specific check. A generic flight crew may not have the required designation or authority to conduct and certify the check.
