The flight crashed during the initial climb phase, shortly after takeoff from Anchorage due to pilot intoxication.[1][2][3] AircraftThe aircraft involved in the accident was a Douglas DC-8-62AF, equipped with four Pratt & Whitney JT3D engines; registered JA8054 to JAL Cargo, a subsidiary of Japan Airlines. The aircraft had a total of 19,744 flight hours, of which 8,708 were since that last major inspection and 45 since the last check. Records showed the aircraft had been maintained within Japanese, American, and ICAO recommendations.[2] Ice on the aircraftMechanics report ice present on the inlet guide vanes, engine cowlings and engine bullet noses, but no ice was found on the aircraft surfaces. A mechanic recommended that the engine anti-icing system be used, but no maintenance was performed on the aircraft in Anchorage. Investigators suspected that ice on the airfoil or transducer may have caused the stall warning to fail. The ice present on the surface of the wings and leading edges could have reduced the angle of attack needed to produce a stall.[2] CrewOn board the aircraft were three flight crew members, two cattle handlers, and live cattle being shipped to Japan as cargo.[1][4] The cockpit crew consisted of:[2] Captain Hugh L. Marsh- 53 year-old Hugh L. Marsh was hired by Japan Airlines on June 24, 1969. He was certified to serve as the pilot-in command of the DC-8 on February 9, 1970; and on October 30, 1969 issued a JCAB airline transport rating, No. 001168, as well as type rated for the DC-8. Due to minor vision impairment he was required to wear corrective glasses for near vision as needed in flight. On September 10, 1970 he was certified as second class navigator. Copilot Kunihika Akitani- 31 year-old Kunihika Akitani was hired by Japan Airlines on May 6, 1970 and certified as a copilot on the DC-8 on August 1, 1976. Flight Engineer Nobumasa Yokokawa- 31 year-old Nobumasa Yokokawa was hired by Japan Airlines on April 1, 1960. On November 20, 1960 he received his flight engineer DC-8 type rating. Yokokawa was also certified to serve as flight engineer on Convair-880 and Boeing 747 aircraft. Pilot intoxicationThe taxi driver who drove Captain Hugh L. Marsh to the airport told investigators that he seemed disoriented. At 04:50 local time a taxi dispatcher phoned JAL and warned of an intoxicated pilot. JAL responded by saying there seemed nothing unusual about the flight crew. Autopsies after the crash showed that the captain was heavily intoxicated, with the initial blood alcohol level 298 mg % and a vitreous alcohol level of 310 mg % taken twelve hours after the crash; the state of Alaska considers 100 mg % legally unacceptable for driving. Of the thirteen people questioned who had spoken with Marsh before the flight, six stated he had been drinking or appeared to be drunk.[2] Flight synopsisAt 05:15 the crew boarded the aircraft; the driver of the crew car stated: "...he was in good condition as far as way's I've seen him sometimes and I made that statement before I ever heard any rumors that he was supposedly drunk or had been partying or whatever." as to whether the pilot appeared intoxicated. Cockpit voice recorder data showed that the crew began the prestart checklists at 06:09; CVR data showed the takeoff was normal until the aircraft slowed acceleration from VR to V2 speed; the aircraft stalled almost immediately after reaching V2 speed. At 0635:39 AST, JAL Cargo Flight 8054 crashed at Anchorage International Airport shortly after takeoff from runway 24L. A witness reportedly saw the flight climb to approximately 100 feet above the ground, veer to the left, and then slide out of the air. All five people on board the aircraft perished in the crash.[1][2] CauseAccording to the National Transportation Safety Board, flight 8054 crashed due to erroneous inputs to the flight controls, factors for such inputs being pilot intoxication and airframe icing. The NTSB noted that the two other flight crew members should have corrected the intoxicated pilot, Hugh L. Marsh, but did not. "The National Transportation Safety Board determines that the probable cause of the accident was a stall that resulted from the pilot's control inputs aggravated by airframe icing while the pilot was under the influence of alcohol. Contributing to the cause of this accident was the failure of the other flightcrew members to prevent the captain from attempting the flight."[2] References1. ^1 2 {{Cite web|url=https://aviation-safety.net/database/record.php?id=19770113-0|title=ASN Aircraft accident McDonnell Douglas DC-8-62AF JA8054 Anchorage International Airport, AK (ANC)|last=Ranter|first=Harro|website=aviation-safety.net|access-date=2017-04-05}} {{Aviation accidents and incidents in 1977}}{{JAL Group}}2. ^1 2 3 4 5 6 {{Cite web|url=http://reports.aviation-safety.net/1977/19770113-0_DC86_JA8054.pdf|title=Japan Airlines, Company, Ltd., McDonnel-Douglas DC-8-62F, JA 8054, Anchorage, Alaska, January 13, 1977.|publisher=National Transportation Safety Board|language=en|ref=Report|accessdate=2017-04-05}} 3. ^{{Cite book|url=https://books.google.ru/books?id=mWCYAAAAQBAJ&pg=PA14&lpg=PA14&dq=Kunihika+Akitani&source=bl&ots=bAuWwAKabb&sig=9D57rq_GbxTC7BCZwVVqaPy5S5k&hl=ru&sa=X&ved=0ahUKEwizrPmt96jJAhWiSXIKHWwzDqkQ6AEIHTAA#v=onepage&q&f=false|title=Confronting Mistakes: Lessons from the Aviation Industry when Dealing with Error|last=Hagen|first=J.|date=2013-08-13|publisher=Springer|isbn=9781137276186|language=en}} 4. ^{{Cite web|url=https://www.planelogger.com/Aircraft/Registration/JA8054/650615?seo=DC-8-62AF_Japan%20Airlines|title=Registration Details For JA8054 (Japan Airlines) DC-8-62AF - PlaneLogger|website=www.planelogger.com|language=en|access-date=2017-04-05}} 6 : Airliner accidents and incidents caused by pilot error|Japan Airlines accidents and incidents|Accidents and incidents involving the Douglas DC-8|Aviation accidents and incidents in the United States in 1977|January 1977 events|Ted Stevens Anchorage International Airport |
