From March 2021 FAA Air Traffic Bulletin:
On August 13, 1985, Captain Jack Brasher was the pilot in command of Republic Airlines Flight 77 from Chicago O'Hare (ORD) to Minneapolis-Saint Paul (MSP). During the flight, with the First Officer at the controls during a climb, the crew deviated from an assigned altitude by 700 feet; however, they quickly recovered to the correct altitude. At the time of the event, no mention of a potential pilot deviation was made to the crew. In fact, Captain Brasher was unaware that the FAA had any concern regarding altitude non-compliance. It was not until almost six months and 150 flights later, Captain Brasher received notification from the FAA of a Notice of Proposed Certificate Action. During the investigation, when asked about the flight, Captain Brasher replied that he had no recollection of the flight or any events associated with the flight.
This event, and the subsequent investigation, served as the catalyst for the current FAA Order JO 7110.65, Air Traffic Control, paragraph 2-1-27, Pilot Deviation Notification, also known as the "Brasher Notification.”
