National Airlines Flight 102 was a cargo flight operated by National Airlines between the British military base Camp Bastion in Afghanistan and Al Maktoum Airport in Dubai, with a refueling stop at Bagram Airfield, Afghanistan. On 29 April 2013, the Boeing 747-400 operating the flight crashed moments after taking off from Bagram, killing all seven people on board.[1][2]

The subsequent investigation concluded that improperly secured cargo broke free during the take-off and shifted to the back of the cargo hold. The change in balance caused the aircraft to pitch up and stall. The shifted cargo also disabled the rear flight control systems, rendering the aircraft uncontrollable and making recovery from the stall impossible.[3]

At the time of the crash the airline had been operating between Camp Bastion and Dubai for a month.[1] The accident flight had originated in Camp Bastion and had stopped at Bagram Airfield to refuel.[4][5] The aircraft then took off from Bagram's runway 03 at 15:30 local time and was climbing through 1,200 feet (370 m) when its nose rose sharply. The aircraft then stalled, crashed, and exploded into a large fireball.[1] The crash site was off the end of runway 03, within the perimeter of the airfield. All seven crew, all of whom were U.S. citizens,[6] died: four pilots, two mechanics, and a loadmaster.[1]

A thunderstorm was also in the vicinity of Bagram at the time of the crash and the wind changed direction by 120° during a one-hour period commencing approximately 35 minutes before the crash.[7] A dashboard camera on a car in the vicinity of the runway end recorded the crash.[1][8] CNN stated that a government official speaking on the condition of anonymity said that the video was authentic.[5]

Aircraft[edit]

The aircraft involved was a Boeing 747-428BCF,[note 1] registration N949CA,[9] S/N 25630.[7] It was manufactured in 1993 as a passenger aircraft and later modified for service as a freighter, seeing service with two other airlines before being sold to National Airlines.[7] At the time of the crash, the aircraft was flying on behalf of the United States Air Force's Air Mobility Command.[1][6]

Crew[edit]

The captain was 34-year old Brad Hasler, who had been working with the Airline since 2004. He had 6,000 flight hours, including 440 on the Boeing 747.[10]:6[11][12][13]

The first officer was 33-year-old Jamie Lee Brokaw, who had been working with the airline since 2009. He had 1,100 flight hours, including 209 hours on the Boeing 747.[10]:10

The relief captain was 37-year old Jeremy Lipka, and the relief first officer was 32-year-old Rinku Shumman.

The loadmaster was 36-year-old Michael Sheets, who had been working with the airline since 2010.[10]:7

The two mechanics were Gary Stockdale and Timothy "Tim" Garrett, both 51 years old.

Aftermath[edit]

The crash interrupted the New Zealand Defence Force's (NZDF) withdrawal from Afghanistan, as it was only hours away from using another National Airlines aircraft to fly equipment out of the country; after the crash the NZDF indefinitely postponed using National Airlines for its airlift requirements.[14]

Investigation[edit]

The United States National Transportation Safety Board (NTSB) and the Afghanistan Civil Aviation Authority investigated the crash.[6] The NTSB reported in a 30 April 2013 press release that representatives of the Federal Aviation Administration and the Boeing Company would also provide technical expertise and aid in the investigation.[15]

On 2 June 2013, investigators from the Ministry of Transport and Civil Aviation of Afghanistan confirmed the load shift hypothesis as the starting point: three armoured vehicles and two mine-sweeping vehicles, totalling 80 tons of weight, had not been properly secured. At least one armoured vehicle had come loose and rolled backwards against the airplane's rear bulkhead, damaging the bulkhead. This also crippled key hydraulic systems and damaged the horizontal stabilizer components - most notably the jackscrew, which rendered the airplane uncontrollable.[3] Control of the aircraft was therefore lost, with the abnormal pitch-up rotation, stall, and crash to the ground ensuing.[1] The damage made it impossible for the crew to regain control of the aircraft.

The NTSB determined that the probable cause of this accident was "National Airlines’ inadequate procedures for restraining special cargo loads, which resulted in the loadmaster’s improper restraint of the cargo."[16] One of the key recommendations was to mandate training for all loadmasters.

In media[edit]

The Canadian TV series Mayday (also known as Air Crash Disaster and Air Emergency in the US and Air Crash Investigation in the UK and the rest of the world) covered Flight 102 in episode 10 of series 16, called "Afghan Nightmare", first broadcast in 2017.[17]

Notes[edit]

  1. ^ The aircraft was a Boeing 747-400 model; Boeing assigns a unique code for each company that buys one of its aircraft, which is applied as an infix to the model number at the time the aircraft is built, hence "747-428". This aircraft was converted to freighter configuration as part of Boeing's conversion program of passenger 747-400s, hence "747-428BCF" for Boeing Converted Freighter.
