The aircraft
The aircraft involved was a 19-year-old
INU failure and failed repair
Following the plane's departure from
At Stansted, the engineers who attempted to repair the ADI did not have the correct Fault Isolation Manual available and did not repair or replace the faulty number 1 INU. One of them identified and repaired a damaged connecting plug on the ADI. When the ADI responded correctly to its "Test" button, they believed the fault had been corrected, although this button only tested the ADI and not the INU. The ADI's input selector was left in the normal position.[2]
Flight crew
The flight crew consisted of:
- 57-year-old Captain Park Duk-kyu (M-R: Pak Tŭkkyu)
- 33-year-old First Officer Yoon Ki-sik (M-R: Yun Kishik)
- 38-year-old Flight Engineer Park Hoon-kyu (M-R: Pak Hun'gyu)
- 45-year-old maintenance mechanic Kim Il-suk (
The captain was a former colonel and pilot in the Republic of Korea Air Force and a highly experienced airman,[8] with a total of 13,490 flying hours – 8,495 of which were accumulated flying Boeing 747s. The first officer, in contrast, was relatively inexperienced with just 195 hours of flying experience on the 747 and a total of 1,406 flight hours. The flight engineer, like the captain, had a lot of experience flying 747s – 4,511 out of his 8,301 total flight hours were accrued in them. The maintenance mechanic had been involved with the failed INU repair.[8]
Flight
It was dark when the plane took off from
Aftermath
After the investigation, the United Kingdom's Air Accidents Investigation Branch (AAIB) issued recommendations to Korean Air to revise its training program and company culture, to promote a more free atmosphere between the captain and the first officer.[8] The first recommendation of the AAIB's final accident report was that:
Korean Air continue to update their training and Flight Quality Assurance programmes, to accommodate Crew Resource Management evolution and industry developments, to address issues specific to their operational environment and ensure adaptation of imported training material to accommodate the Korean culture.[2][1]
In popular culture
A March 2012 episode of Mayday also called Air Crash Investigation in the U.K. and the rest of the world (Season 11 Episode 7) titled "Bad Attitude" or "Stansted Crash" investigates this accident.[8]
