When a repair station completes work on an aircraft and wants to return that aircraft to service, we all know that someone has to sign the aircraft’s logbook. But “who” is required to sign has been a confusing issue (at least it has been confusing for some FAA personnel). Fortunately, the FAA’s Office of the Chief Counsel answered that question and set the FAA personnel straight in a recent legal interpretation. For an answer to the question and a discussion of the interpretation please read my latest article on the topic:Who Can Return An Aircraft To Service On Behalf Of A Repair Station.
