Background
On 3 February 2022, three aircraft belonging to a Civil Aeronautics Instruction Center (CIAC) scheduled an instructional navigation flight between Villarrica Aerodrome (SCVI) and Cañal Bajo Aerodrome (SCJO). A departure order was established for the three participating aircraft.
Aircraft and Crew
Aircraft N°1 was commanded by a commercial pilot with a flight instructor rating. Aircraft N°2, a Cessna 172S, was under the command of a commercial pilot with an assistant flight instructor rating, accompanied by three student pilots. Aircraft N°3 was commanded by a flight instructor.
Sequence of Events
After takeoff, the three aircraft were to proceed to the Licanray area, approximately 20 km south of Villarrica, and then continue to their final destination in Osorno. However, after departure, around 18:30 local time, the flight instructor of aircraft N°1 contacted the pilot in command of aircraft N°3 by radio, inquiring if they had information on aircraft N°2, as its transmission on the frequency had not been heard since the notification of its takeoff.
Accident
The Cessna 172S ended up crashed on the northwestern slope of Villarrica volcano on 3 February 2022 at 19:00 local time.
