Follow-up / safety actions
Operations had been voluntarily suspended after August 4, 2018. The Swiss Federal Office of Civil Aviation (FOCA) allowed operations to be conducted per August 17 since the investigation by the STSB had not yet brought to light any technical problems with the accident aircraft. However, JU-Air first had to comply with the precautionary measures of the FOCA to commence flight operations. First, the FOCA required that, for the time being, a minimum altitude above the legal minimum altitude be maintained. Secondly, JU-Air’s aircraft had to carry a GPS data recorder that records every flight and allows subsequent assessment of the route. Third, the passengers should also remain strapped during the flight and not be able to circulate freely in the aircraft. This also applies to visits to the cockpit during the flight.
