On November 21, 1977, Austral Líneas Aéreas Flight 9 crashed near Bariloche, Argentina, resulting in the deaths of 46 out of the 79 individuals aboard.[1]: 1, 5 [2]
Accident
Three planes had been arranged to transport 31 newlywed couples to Bariloche for their honeymoon, with the aircraft involved being the second to take off.[3] While ascending to an altitude of 35,000 feet (11,000 m), the aircraft encountered issues with cabin pressurization and was forced to descend to 29,000 feet (8,800 m). At 00:40, clearance was granted for an Instrument Landing System (ILS) approach to runway 28; however, this approach was aborted due to problems with the VOR receiver. The pilot then requested permission for a visual approach to runway 10 but subsequently opted to attempt another ILS approach to runway 28. The final communication from Flight 9 came when the pilot reported proximity to the VOR beacon. Shortly thereafter, the plane collided with a mountain, resulting in fatalities among all five crew members and 41 passengers.[4]</ref>
Investigation
The inquiry concluded that the crew descended earlier than permitted and failed to adhere strictly to the ILS approach procedures. These errors were possibly influenced by malfunctions in the VOR signal and factors related to the captain’s psychological condition.[1]: 10
