Korean Air 801
Korean Air Flight 801 Departed Seoul, Korea At 0142 On The 6th Of August, 1997 For Guam International Airport. It Crashed Into High Terrain While Flying A Nonprecision Approach To Runway 6L. The Airplane Had Two Pilots, One Flight Engineer, 14 Flight Attendants And 237 Passengers On Board. Only 26 People Survived.
At 0111 Local Time, The Captain Briefed A Nonprecision Approach For Runway 6L, Which Included Mention Of The Unusable Glideslope.
Upon Joining The Localizer At 0139 Local Time, The Aircraft Descended Through 2,800 Feet With The Flaps Extended 10 Degrees. The First Officer Was Heard Saying “Glideslope (Unintelligible)…Localizer Captured…(Unintelligible Words)…Glideslope Did.” Right After This, The Controller Cleared Them For The ILS Runway 6L And Reminded The Flight Crew That The Glideslope Was Unusable.
The First Officer Responded With “Cleared ILS Runway 6L” Without Acknowledging The Unusable Glideslope. At This Point, We Can Begin To Hypothesize That The Crew’s Shared Mental Model Was Unreliable. The NTSB Accident Report States The Following:
According To The CVR, About 0139:55 The Flight Engineer Asked, “Is The Glideslope Working? Glideslope? Yeh?” One Second Later, The Captain Responded, “Yes, Yes, It’s Working.” About 0139:58, An Unidentified Voice In The Cockpit Stated, “Check The Glideslope If Working?” This Statement Was Followed 1 Second Later By An Unidentified Voice In The Cockpit Asking, “Why Is It Working?” About 0140:00, The First Officer Responded, “Not Useable.”
