Category:Accident
Location:Gapyeong, 37 mi NE of Seoul -   South Korea
Phase: Approach
Nature:Private
Departure airport:Jamsil Heliport
Destination airport:Cheongshim Hospital
Narrative:
Operated by Tong-il Aviation for the Korea Family Federation Missionary for World Peace and Unification as a private aircraft. Times Aerospace Korea Limited Liability Corp. had initially registered this as a private aircraft on 1 June 2006. Title transferred to the Mission 24 July 2006.

While approaching to land, operating under VFR, the aircraft passed the heliport in clouds. Then the pilot performed a go-around but lost control and crashed into trees halfway up the Janglak Mountain.

HL9292 was totally destroyed by a fire that broke out immediately after the crash, and of the 16 persons on board, six including the captain were seriously injured and 10 had minor injuries.

The Aviation and Railway Accident Investigation Board determined that the probable cause of this accident was that despite that the flight crew could not visually identify the helipad because it was covered with clouds in bad weather conditions, they attempted to land unreasonably at a high speed in the autopilot mode and failed to maintain a proper flight attitude during the go-around, so they impacted on the ground.

Contributing to the accident were ①the flight mission was decided to be made in variable bad weather conditions, ②the co-pilot failed to give proper advice to the captain on the flight mission, en-route flight, final approach and the captain's improper decision and action in the go-around section after passing the helipad, and when the captain lost the flight attitude in a vertigo, he failed to take a proper defensive action, ③despite that the weather was not suitable for visual flight due to an indirect influence of typhoon, the Tong-il Aviation failed to provide the captain with positive operational support such as analyzing weather trends or recommending cancellation of the flight mission, and ④the EGPWS was unservicable (iaw MMEL flight is not allowed in case of its malfunction but the aircraft was operated without an MEL).
