What happened
On March 18, 2019, an Avianca Airbus A330-243, registered as N342AV, was involved in a technical incident at Ministro Pistarini International Airport (Ezeiza) in the province of Buenos Aires, Argentina. The aircraft, operating a regular international commercial flight from El Dorado International Airport in Colombia, had successfully completed its landing sequence.
While the aircraft was performing taxi operations following its arrival, the flight crew observed a cockpit indication signaling a low level of hydraulic fluid within one of the aircraft's hydraulic circuits. No injuries were reported among the 255 occupants on board, and the aircraft sustained no damage during the event.
The investigation
The investigation focused on the technical alert received during the post-landing taxi phase. Authorities examined the operational sequence from the arrival at Ezeiza to the moment the hydraulic system alert was triggered. The scope of the inquiry centered on the functionality of the hydraulic monitoring systems and the specific circuit that reported the low fluid level.
