On December 10, 2019, a Piper PA-60 Aerostar (Ted Smith 600) (registration C-FQYW) operated by Private Canada was involved in an aviation accident near Gabriola Island, Canada during landing or approach. 3 people were killed. Investigators recorded the probable cause as: The occurrence aircraft was equipped with a BendixKing KI 825 electronic horizontal situation indicator (HSI) that was interfaced to the flight control system and GPS (global positioning system) Garmin GNS530W/430W. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 8 related events involving the same aircraft type or operator are linked below.
A Piper Aerostar PA-60-602P (C-FQYW) crashed on Gabriola Island, BC, on 10 December 2019, killing all three occupants after an instrument approach in poor weather.
The occurrence aircraft was equipped with a BendixKing KI 825 electronic horizontal situation indicator (HSI) that was interfaced to the flight control system and GPS (global positioning system) Garmin GNS530W/430W. The HSI also supplies the autopilot system with heading information. The investigation determined that the HSI had failed briefly during operation on 22 November 2019 and a 2nd time, 3 days later, on 26 November 2019. The KI 825 HSI is electrically driven and therefore is either on and working, or off and dark with no display. The aircraft owner was in contact with an aircraft maintenance organization located at Boundary Bay Airport (CZBB), BC, and an appointment to bring the occurrence aircraft in for troubleshooting of the 2 brief HSI malfunctions had been made for 11 December 2019, i.e., the day after the accident. In total, 13 flights had been conducted after the 1st failure of the HSI. There were no journey log entries for defects with the HSI or evidence of maintenance completed. Regulations require that defects that become apparent during flight operations be entered in the aircraft journey logbook, and advisory guidance in the regulatory standards states that all equipment required for a particular flight or type of operation, such as the HSI in this case, be functioning correctly before flight. The HSI was destroyed in the accident and the investigation was unable to determine if it was operational on impact. Similarly, it could not be determined if the HSI was supplying the autopilot with heading information, or if the autopilot was engaged during the approach.
