𝗞𝗼𝗿𝗲𝗮𝗻 𝗔𝗶𝗿 𝗙𝗹𝗶𝗴𝗵𝘁 𝟴𝟬𝟭 was a scheduled international passenger flight from Seoul to Guam, operated by a Boeing 747-300 (Reg. HL7468) on 𝗔𝘂𝗴𝘂𝘀𝘁 𝟲, 𝟭𝟵𝟵𝟳.
The plane departed Seoul at 21:53. Upon arrival to the Guam area, the first officer made initial contact with the Guam CERAP controller about 01:03. At 01:39 the controller stated, "Korean Air 801 cleared for ILS runway 6L approach...glideslope unusable." The first officer responded, "Korean 801 roger...cleared ILS runway 6L" The flight engineer then asked, "is the glideslope working? glideslope? yeh?" One second later, the captain responded, "yes, yes, it's working." One second later an unidentified voice asked, "why is it working?" About 01:40:42, the CERAP controller instructed Flight 801 to contact the Agana control tower. About 01:41:01, the Agana tower controller cleared Flight 801 to land.
About 01:42:14, as the plane was descending through 840 feet msl and the flight crew was performing the landing checklist, the GPWS issued a "minimums minimums" annunciation followed by a "sink rate" alert about 3 seconds later. About 01:42:19, as the plane descended through 730 feet msl, the flight engineer stated, "200 [feet]," and the first officer said, "let's make a missed approach." As the plane descended through 670 feet msl, the autopilot disconnect warning sounded. About 01:42:26, the plane impacted hilly terrain at Nimitz Hill about 660 feet msl. It struck trees and slid through dense vegetation before coming to rest. A post-impact fire broke out.
𝗣𝗿𝗼𝗯𝗮𝗯𝗹𝗲 𝗖𝗮𝘂𝘀𝗲:
"The captain's failure to adequately brief and execute the nonprecision approach and the first officer's and flight engineer's failure to effectively monitor and cross-check the captain's execution of the approach. Contributing to these failures were the captain's fatigue and Korean Air's inadequate flight crew training. Contributing to the accident was the Federal Aviation Administration's intentional inhibition of the minimum safe altitude warning system and the agency's failure to adequately to manage the system."
