Additional Investigation
After the first issue of the preliminary report several subjects were investigated additionally. By pure coincidence an aircraft spotter took some photographs of El Al 1862 when it arrived at Schiphol Airport on October 4, 1992. On these photographs it appears that engine no 3 has an upward tilt in relation to the other three engines. The question arose whether this upward tilt could have been caused by disconnections of the wing to strut attachments. Experts explained that a disconnection could not possibly result in a tilt as shown on the photographs. Because a transit maintenance check (including condition of engine and strut) was properly carried out and also because the Board at this stage of the investigation became aware of the technical improbability that pylon no.3 attachments had failed prior to the accident flight, further investigation on this subject was put aside. Another subject of additional investigation was the question if the
depleted uranium balance weights in the El Al Boeing represented potential health hazards. From the originally installed depleted uranium weights, two were replaced by Tungsten so not more than 400 kg. of depleted uranium was involved in the crash and the fire
