A mechanic reported a cessna 172 was flown in an unairworthy condition due to the annual inspection ...

Narrative:

Aircraft was operated in an unairworthy condition. The aircraft in question had been out of annual for 4 days at the time of this error. The guidance given to me from another mechanic concerning 'ferry permits' was inaccurate or misunderstood by me. I was informed that a ferry permit was to accommodate a single flight to reposition an aircraft to a location where maintenance could be performed; provided it was inspected by an authorized mechanic (me) and a log entry made certifying that the aircraft was in a condition for safe operation. I was not aware; until after I returned that I violated two of the conditions required for a ferry permit.1. It must be approved by the FSDO associated with the flight's origin (not the inspecting mechanic)2. Only required crewmembers are allowed on the flight.I was under the impression that the only requirement for a ferry permit was to make an entry in the logbook that the aircraft was safe for operation with the restriction that the flight only be to reposition the aircraft to a base where the maintenance could be performed. I have since read; and I now understand the details that are involved in requesting a ferry permit.
