The FAA is reconsidering its policy surrounding in-person supervision of unlicensed mechanics and plans revised or new guidance.

The FAA has issued a stay on a legal interpretation that would have required supervising aircraft mechanics to observe apprentices closely enough to intervene if needed, according to the Aeronautical Repair Station Association (ARSA).

Referred to as the Moss Interpretation, the response was from an FAA lawyer to a request for clarification by Little Rock, Arkansas Flight Standards District Office manager Jonathan Moss. His request sought to determine whether it is legal for mechanics to supervise non-licensed technicians remotely—for example, via streaming video calls or similar technology.
