Japan Airlines Flight 446 was a Japan Airlines flight from Sheremetyevo International Airport of Moscow, Russian SFSR, Soviet Union to Tokyo International Airport (Haneda Airport) in Ōta, Tokyo, Japan.

On November 28, 1972 the DC-8-62 on the route crashed during the initial climb phase upon takeoff from Sheremetyevo. While it is established by investigation that the direct reason for the crash was stalling shortly after takeoff, the Soviet Accident Investigation Committee noted the possibility of accidental deployment of the spoilers and reduced thrust due to engine problems as the cause for this accident.
Accident
On November 28, 1972, Japan Airlines Flight 446, operated by JA8040 (a DC-8-62), departed from Copenhagen Airport, Denmark bound for Tokyo International Airport, Japan with an intermediate stop at Sheremetyevo International Airport. At 7:51 PM Moscow time (1:51 AM, Nov 29 for Tokyo time), the flight took off from Sheremetyevo, reached an altitude of 100 m, stalled, and crashed 150 m beyond the runway end, 30 seconds after leaving the ground.
On board were 6 flight crew (3 of them backup crew), 7 cabin crew, 1 employee of Japan Airlines, and 62 passengers (of whom 52 were Japanese). All except for 5 flight attendants and 9 passengers (of whom 8 were Japanese; the other was E. Bruce Smith of New Zealand) perished, which made 62 fatalities. All survivors were seated near first-class seats located in the front section of the fuselage, suffering severe injuries.
The aircraft involved, JA8040, was delivered on July 1969, and written off less than 3.5 years after its delivery, thus being the most short-lived among Japan Airlines' DC-8s. This aircraft was noted for previous involvement in several major incidents: with the nickname Hida, it was used to carry passengers involved in the hijack of Japan Airlines Flight 351 back to Japan in April 1970; on November 6, 1972, 22 days before the crash, this plane was offered to the hijackers of the JA351 hijack in response to their demand to flee to Cuba, although they were ultimately arrested at Haneda Airport.
This was the second fatal accident within the same calendar year for Japan Airlines, following Japan Airlines Flight 471 in June.
Reason
The Soviet Accident Investigation Committee released (according to ICAO standard) the result of CVR and FDR data analysis.
CVR transcript:
00s (Takeoff roll begin)
10s "Time?" "Time is OK." "It's a bit slow..."
25s "Yes." "What?" "We are going."
30s "V1." at 129kt(IAS)
40s "Rotation." "Attention." at 145kt
45s "V2." at 154kt
50s (Mechanical sound)
55s "What's up?" "Spoiler!" at 350ft
60s "What's this?!" "Sorry..." "Left clear." at 300ft
65s "Engine! Engine! No.2! No.2 Engine!" at 100ft
The survivors reported three abnormal situations indicating an engine failure, which matched the description of eyewitnesses on the ground:
The direct reason to the crash was an excessive nose-up attitude leading to a stall. The cause was determined to be one of the following by both sides (Japanese and Soviet investigating personnel):
Based on the above, the sequence of the entire accident could be presumed (but not determined) that:
There was a largely believed theory that the copilot mistook the ground spoiler lever as the landing gear lever. Not impossible as in our days still happens that flaps retraction is done instead of gear retraction. It may happen with spoilers, too.
Public reaction
The accident was attributed to pilot error, i.e. the co-pilot's lack of adequate attitude. The voice recorder recorded some of the captain's insensitive colloquial conversation, such as "Yeah(はいよ)" "Kay, Here we goin(やっこらさ)"note. After reports containing the information above was released to the public, Japan Airlines drew much criticism, such as "our floppy flag carrier" from public media, and the problem was even presented before the Diet of Japan.
Apart from this accident, Japan Airlines suffered several other incidents attributed to human error in the same year: Haneda Airport overrun incident (on May 15), New Delhi crash (on June 14), Gimpo Airport overrun incident (on September 7), Bombay Airport overrun incident (on September 24). As a result, the airline suffered harsh criticism from the public.
In the popular comic strip Sazae-san, Machiko Hasegawa made a sarcastic scene, referring to these accidents:
While preparing for a business trip, Namihei panicked when he heard Sazae and Wakame talking about "Nikkō ´falling´ again", and rushed toward them.
But it turned out that the two was just watching the sunset. Relaxed, Namihei shouted "Please say ´Nikkō is descending´ !"
Aftermath
On DC-8s, spoilers are used after landing only (i.e. ground spoiler). Few methods can be used to reduce speed in flight (e.g. before landing), such as deploying the thrust reverser of inner engines on both port and starboard side. Other accidents attributed to accidental deployment of ground spoiler in flight have also occurred. As a result, modifications were done to make ground spoilers unable to deploy in flight altogether.
There are emergency air brakes installed on DC-8s.
"Safety badge"
According to the wish of the families of victims, "Don't forget the pain of the accident and remember to take adequate safety measure", a green cross "safety badge" is attached to the uniforms of all employees of Japan Airlines. During the merge of the airline system of Japan in 2002, uniforms were changed, so the safety badge was dropped. However, on every anniversary of the accident, all employees of the Moscow branch of Japan Airlines would visit the memorial of the victims, and mourn the dead.
As recently as 2010, many of the survivors annually meet around the anniversary of the crash. Noriko Hatanaka of Japan's AOPA and fellow survivor, is the regular coordinator of each annual reunion.
