According to the FAAs website, a licensed pilot has a mandatory duty to report any of the following occurrences:
"Examples of Reportable Administrative Actions (Not a comprehensive list)
Examples of Reportable Convictions (Not a comprehensive list)
Note: Under 14 CFR 61.15, all pilots must send a Notification Letter (MS Word) to FAA�s Security and Investigations Division, within 60 calendar days of the effective date of an alcohol-related conviction or administrative action."
Pilots should therefore take special care with a DUI and/or DMV administrative hearing ("APS") to avoid FAA difficulties.
