On 17 October 2019, a Saab 2000 overran the Unalaska runway after touchdown following difficulty braking and exited the airport perimeter before finally coming to rest on shoreline rocks. The Investigation attributed the poor braking to incorrect brake system wiring originating during maintenance some 2½ years earlier but noted the touchdown occurred with crew awareness that the prevailing tailwind component was well in excess of the permitted limits with no reason not to use the into-wind runway and attributed this to plan continuation bias. The aircraft operator’s failure to apply their specifically-applicable airport qualification requirements to the Captain was noted.
