Yokota AFB (Tokyo)

The crew started their duty for the flight from Yokota, near Tokyo, Japan to Singapore at 1000 hours local time (0900 hours Singapore time) on 13 December 2002. The aircraft departed Yokota at 1125 hours local time (1025 hours Singapore time). The FO was the handling pilot for the flight. The expected flight time was about 7 hours. The departure and en route segments of the flight proceeded normally. The crew was aware of Changi Airport’s ATIS ‘Y’ weather information provided at about 1640 hours through Changi Airport’s there were thunderstorm activity, low level windshear and heavy rain in Singapore. The aircraft was given clearance to land on Runway 20R. The FO briefed the other crew members on landing on 20R. At about 7 miles from the airport, Changi Tower advised the aircraft that the wind was from 350 degrees at 5 knots, that the runway surface was wet, that the visibility from the Tower was about 1,000 metres and that landing traffic had reported the braking action at the end of Runway 20R to be from medium to poor. The approach and landing was carried out in heavy rain. The approach was stabilized and normal. Approach speed was about 148 knots. Flaps 35 were used. At about 300 feet above ground, the PIC reported having the approach lights and runway lights in sight while the FO still could not see the lights as the rain removal for the windshield on the FO’s side was not effective. According to the FO, he felt the PIC was putting his hands on the controls of the aircraft. The PIC noticed that the aircraft had drifted slightly left of the runway centreline and told the FO to make the correction back to the centerline. Although the FO made the correction, he was still unable to see the approach lights clearly at about 200 feet. The FO indicated he felt the PIC was in control of the aircraft and making corrections and so he let go of the controls. The CVR recording suggested that the PIC was aware the aircraft was floating down the runway and that the PIC informed the crew that “We are floating way down the runway.” The PIC subsequently moved the control column forward to make a positive landing. The aircraft landed at 1743 hours. The aircraft was observed by an air traffic controller to have touched down on the runway at a point roughly abeam the Control Tower and just before the turn-off for Taxiway W6, which was about 1,500 metres from the end of the runway. Two Airport Emergency Service officers of the Civil Aviation Authority of Singapore also observed that while most aircraft landing on Runway 20R would touch down at a point between the turn-offs for Taxiways W3 and W4, the Arrow Air aircraft floated way beyond the normal touchdown zone. The aircraft’s speed at the time of touchdown was estimated from flight data recorder data to be about 135 knots. Upon touchdown, the PIC deployed spoilers and thrust reversers. The thrust reversers for Engines Nos. 1, 2 and 3 deployed almost immediately while that of Engine No. 4 was reportedly slow in deployment. The PIC and FO also pushed hard on the brake pedals, but they felt that there was no braking response. The aircraft did not stop before reaching the end of the runway. It veered slightly to the right as it exited the runway. The speed of the aircraft when it left the runway was about 60 knots. The aircraft rolled in mud during the overrun. The nose landing gear broke off half way during the overrun and the aircraft came to rest in a grass and soggy area at about 300 metres from the end of the runway. There was no fire. After the aircraft had come to a complete stop, the PIC stowed the thrust reversers. The crew completed the evacuation checklist and exited the aircraft from Door L1 with the assistance of the Airport Emergency Service personnel who had already arrived by then.

The airplane was conducting a flight from Clark AFB, Philippines, to McChord AFB with intermediate stops at Kadena AFB, Okinawa, and Yokota AFB, Tokyo, carrying 16 people among them six marines. En route to McChord, while cruising by night, the crew established contact with ATC and was cleared to descend from FL370 to FL150 then FL100. Few minutes later, after confusing the C-141 with another Navy aircraft, the air traffic controller cleared the crew to descent to 5,000 feet which was a too low altitude for the area. While descending at an altitude of 7,000 feet in limited visibility, the four engine airplane struck the slope of Mt Constance (7,756 feet high) located in the Olympic National Park, about 52 miles northwest of McChord AFB. The airplane impacted the mountain about 150 feet below the summit and caused an avalanche. Debris were found scattered on a wide area and none of the 16 occupants survived the crash.

The airplane was completing a charter flight from McChord AFB to Cam Ranh Bay, Vietnam, with intermediate stops in Anchorage and Yokota, carrying 219 military personnels and 10 crew members. During the takeoff roll on runway 06R at Anchorage-Intl Airport, the airplane failed to gain sufficient speed and to get airborne. After V1 speed, the crew decided to abort the takeoff procedure but the airplane overran, struck a wooden barrier, an ILS structure, a 12-foot deep drainage ditch and came to rest in flames. A crew member and 46 passengers were killed while 182 other occupants were evacuated, 163 of them were wounded. The aircraft was destroyed by a post crash fire.

While taxiing to the runway for takeoff the crew completed the Before Takeoff Checklist. The copilot inadvertently missed the item referring to the automatic Spoiler Select Switch. The switch should have been in the "Rejected Takeoff" (RTO) position, but was in the "Autoland" position when the airplane departed. Unnoticed by the crew, between 34-60 Knots, the spoilers automatically deployed to the ground position. The crew noticed a reduced acceleration rate, but elected to continue the takeoff. The aircraft became airborne, accelerated poorly and began a shallow descent. It crashed into the sea just off the end of the runway. Six crew members were killed while two others were rescued.
Those killed were:
Maj Harry Milton Brenn,
Cpt Morris Bowdoin Witt,
SMS Roy Earl Shults,
M/Sgt Herman Eugene Miller,
T/Sgt Marshall Edward Brown,
T/Sgt Harold Eugene Mahy.

The aircraft was engaged in a special flight from Kadena AFB to Yokota AFB, carrying a spare engine to repair another KC-135 grounded at Yokota Airbase. During the takeoff roll, after a course of 2,100 meters, the crew started the rotation when the airplane stalled and struck the runway surface before taking off again. Once it reached the height of 100 feet, it stalled again and crashed in a huge explosion 100 meters to the left of the extended centerline and about 150 meters past the runway end. The aircraft was totally destroyed and all 11 occupants were killed as well as one motorist on the ground.

The aircraft was on its way from Misawa AFB to Yokota AFB with 11 crew members on board. Following an uneventful refuelling mission, something went wrong and the airplane went out of control. Four crew members were able to bail out before the aircraft crashed in a mountainous area located in the region of Fukushima. The seven crew members who remained in the cabin were killed.

While on a local training flight in the region of the Yokota AFB, the four engine aircraft struck the slope of Mt Chichibu locate some 35 km northwest of the airbase. All seven crew members were killed.

Crashed in unknown circumstances near Yokota Airbase, killing all six crew members.

En route from Wake Island to Yokota AFB, Tokyo, while cruising at an altitude of 8,000 feet, the crew informed ground about his position 320 km off the Japanese coast and that all was ok on board. Shortly later, the airplane disappeared and the crew was unable to send any distress call. SAR operations were conducted for eight days but no trace of the airplane nor the 67 occupants was ever found.

The crew was engaged in a weather mission for typhoon 'Emma' but failed to return to his base at Yokota AFB. The exact circumstances of the accident remains unknown and all 16 crew members have been killed.
