The 1979 Garuda Fokker F28 crash occurred on 11 July 1979 when a Garuda Indonesian Airways Fokker F28 airliner on a domestic flight in Indonesia from Talang Betutu Airport, Palembang, to Polonia International Airport (now Soewondo Air Force Base), Medan, struck Mount Sibayak at 5560feet on approach to landing, with no survivors.
The aircraft had departed Palembang 80 minutes earlier and had been cleared for an approach to runway 05 at Medan Airport. The aircraft was asked to report passing the nondirectional beacon (NDB) "ON" at 2500feet. The pilot then reported he was maintaining a height of 9300feet as the NDB was unreliable. The approach controller then asked them to maintain that height until after they had passed the NDB. The pilot then reported they were at 6000feet. The aircraft struck the 7200adj=midNaNadj=mid volcano Mount Sibayak at 5560feet.
