These pilot deviations need to be examined to determine if a common thread exists that we should address to help reduce the number of deviations that continue to occur and thus enhance aviation safety.
In the reporting period from April 11, 2025, through May 16, 2025 there were twenty-four pilot deviations reported by the FAA SDL FSDO. These deviations were committed by pilots with certificates ranging from Student Pilot through ATP/CFI Pilot, and a military pilot. There were ten out of state pilots that committed these deviations, there was only one Brasher issued for an IFR deviation.
Note: A controller will issue a Brasher notification to a pilot when further FAA action will be taken, and the controller is thus giving the airman the opportunity to make note of the occurrence, collect information, and their thoughts for their future interaction with FAA Flight Standards.
The deviations weren’t as serious as past reports because apparently there was a need to issue only one Brasher for an IFR deviation. Obviously, pilots don’t get the message to be more careful in their flying. Some of these pilots may not be accustomed to flying in some of the complex/crowded airspace that we have in Arizona.
I would certainly like to think that the information presented has been valuable to pilots out there and will make them safer pilots.
Moving on, pilots must listen carefully to ATC instructions and comply with them, and if they can’t comply, tell ATC why they cannot. Also, when flying in controlled airspace, pilots should never do something on their own but always talk to ATC before they do anything that may differ from the instructions given. Pilots must always be aware of what type of airspace they are flying in, or may be about to enter, and know what may be expected of them. Always observe the airport, and runway markings, and signs and obey them. Fly with care and forethought, and don’t be part of the problem.
