Weigel was not fit to fly, since his license had expired. Even though these personal issues surrounding the pilots had a very significant influence on the accident, the legal investigation performed in the following years centered on proving that the pilots were not entirely to blame, but that the lack of controls by the Air Force and LAPA's organizational culture also played a role in the events leading to the crash. Accident As the aircraft started its takeoff run, the take-off warning system (TOWS) sounded an alarm in the cockpit, indicating that the aircraft was not correctly configured for the maneuver. The crew ignored the warning and continued the takeoff, not realising that the flaps were not at the required take-off position and were instead fully retracted, thus preventing the aircraft from lifting off. The jet overshot the runway, breaking through the airport's perimeter fence, crossed a road, hitting an automobile in the process, and finally collided with road construction machinery and a highway median. Fuel spilling over the hot engines and gas leaking from a damaged gas regulation station resulted in a fire that destroyed the aircraft. The Junta de Investigaciones de Accidentes de Aviación Civil (JIAAC) determined that the pilots failed to configure the aircraft correctly for take-off. The penal prosecution focused on proving that the company's policies and organization, lacking the Argentine Air Force's controls, were the main factors that led to the accident. For instance, it was mentioned that a pilot was allowed to fly without a license by the company. Because of these perceived flaws, some of LAPA's directors and the Air Force staff responsible for monitoring the airline were taken to jury trial. Flight review The JIAAC review of the flight reads: The evening of the accident, the captain arrived at the Aeroparque Jorge Newbery one hour before take-off, as usual, in order to perform a regular commercial flight (LAPA 3142), on which 95 passengers and 5 crew members were to be transported to the destination airport Ingeniero Ambrosio Taravella in the city of Córdoba. He arrived before the first officer and had an informal conversation with the flight dispatcher on duty. The aforementioned briefing started with the rest of the flight's crew, and when the first officer arrived, they went back over the weather conditions –which were good– and the NOTAMs for the destination airport as well as for alternative ones. Both pilots
