Japan Air Lines Flight 350 crashes near Haneda Airport in an attempted pilot mass murder-suicide, killing 24 of the 174 people on board.

Japan Air Lines Flight 350 was a McDonnell Douglas DC-8-61, registered JA8061, on a domestic scheduled passenger flight from Fukuoka, Fukuoka Prefecture, to Tokyo in Japan. The airplane crashed 9 February 1982 on approach to Haneda Airport in Tokyo Bay, resulting in 24 fatalities. Flight 350 was the first crash for Japan Air Lines in the 1980s. The investigation traced the cause of the crash to the deliberate actions of the captain.

Haneda Airport , also known as Tokyo International Airport and sometimes abbreviated to Tokyo-Haneda, is the busier of the two international airports serving the Greater Tokyo Area, the other being Narita International Airport (NRT). It serves as the primary domestic base of Japan's two largest airlines, Japan Airlines and All Nippon Airways, as well as RegionalPlus Wings Corp., Skymark Airlines, and StarFlyer. It is located in Ōta, Tokyo, 15 kilometers (9.3 mi) south of Tokyo Station. The facility covers 1,522 hectares of land.

Suicide by pilot is an aviation event in which a pilot deliberately crashes or attempts to crash an aircraft as an act of suicide, with or without the intention of causing harm to passengers on board or civilians on the ground. If others are killed, it may be considered an act of murder–suicide. It is suspected to have been a possible cause in several commercial and private aircraft crashes and has been confirmed as the cause in other instances. Determining a motive can be challenging and sometimes impossible for investigators to conclude especially if the suspected pilot sabotages or disengages their in-flight recorder or in-flight tracker. In the United States, investigations are primarily undertaken by the National Transportation Safety Board and the Federal Bureau of Investigation (FBI).
