The aircraft continued its descent until it began striking the approach lights approximately from the threshold of runway 22L . } } Of the 124 people on board, 107 passengers and 6 crew members died as a result of the crash.

,Juba International Airport had a new runway light system commissioned with simple approach lights for Runway 13 / 31, runway edge lights, taxiway lights for Exit Delta, Apron edge lights, illuminated windsocks, ATC tower rotating beacon as well as PAPI for both approaches ..

Flight 1420 from Dallas / Fort Worth Airport slid off the runway at 11 : 51 p . m . at a speed between 92 and 103 mph, went down an embankment, struck steel supports for runway approach lights, broke apart and caught fire.
44.
Executive has three runways, two lighted : Runway 2 / 20 measures 5, 503 ft x 150 ft . A Medium Intensity Approach Light System with Runway Alignment Indicator Lights ( MALSR ) is installed on Runway 2, while REIL and VASI are on Runway 20.
45.
With this requirement formulated, impact experiments were carried out ( 1976 2000 ) on commercial and experimental approach light masts in the US, Sweden, The Netherlands, Finland, Norway and Canada, with light wing structures impacting the masts at velocities of up to 140 km / h.
46.
Contributing to the accident were the pilots failure to make standard callouts and the current Federal Aviation Regulations that allow pilots to descend below the minimum descent altitude into a region in which safe obstacle clearance is not assured based upon seeing only the airport approach lights.

;August 31, 1988 : CAAC Flight 301, a Hawker Siddeley Trident 2E ( B-2218 ), struck approach lights at Kai Tak Airport and struck a lip, collapsing the right main landing gear; the aircraft then slid off the runway into Kowloon Bay, killing 7 of the 89 on board.

The captain directed the plane to go off the end of the right half of the runway in an effort " to go beside the stanchions holding the runway lights " and thus avoid a collision with the approach light stanchions, which were positioned immediately beyond the end of the runway.
49.
Nonetheless, violating standard procedures, the captain decided to continue the approach to as close as to the runway and descended further to and beyond, well below the MDA . At off the threshold of the runway and at an altitude of ( which in this case constituted the approach lights at a speed of around.
50.
Upon reaching MDA of, Lutz declared that he had " ground contact " and would continue on, then deliberately descended the plane below the minimum descent altitude ( MDA ) without having the required visual contact with either the approach lights or the runway, a major piloting error that ultimately led directly to the crash.
