What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The day before the accident flight a line service tech (uncertificated person) had towed the aircraft and subsequently broken the tow lugs off the scissor's pin. The line service tech removed the broken pin for reasons unknown. He informed the mechanic on duty a new pin was needed but did not tell him he had removed the pin.
The day of the flight the pilot asked the mechanic about the broken tow lugs. The mechanic told him the aircraft was "good to go" as is. The line service tech was not on duty that day and thus the removed pin was not discovered prior to the flight.
