The Bijlmerramp (in English: Bijlmer disaster) was an airplane crash. On October 4, 1992, El Al Flight 1862, a Boeing 747 cargo plane of the Israeli El Al airline crashed into the Groeneveen and Klein-Kruitberg flats in the Bijlmermeer (colloquially "Bijlmer") neighbourhood (part of 'Amsterdam Zuidoost') of Amsterdam, the capital of the Netherlands. A total of 43 people were killed, including the plane's crew of three and a nonrevenue passenger in a jumpseat. Many more were injured.

The plane's cargo included, amongst other things: bullets, spare parts for AIM-9 Sidewinder missiles, spare parts for Patriot missiles and 190 litres of dimethyl methylphosphonate.
Dimethyl methylphosphonate is not classified as toxic, but is harmful if inhaled, swallowed or absorbed through the skin. The primary commercial use of dimethyl methylphosphonate is as a flame retardant. Other commercial uses are a pre-ignition additive for gasoline, anti-foaming agent, plasticizer, stabilizer, textile conditioner, antistatic agent, and an additive for solvents and low-temperature hydraulic fluids. It is a Chemical Weapons Convention schedule 2 chemical used in the synthesis of Sarin nerve gas. The shipment was from a U.S. chemical plant to the Israel Institute for Biological Research under a U.S. Department of Commerce licence.
After the disaster, there were rumours that the Israeli secret service had tried to recover some of the cargo, or the flight recording boxes. The plane, like all Boeing 747s at that time, also contained about 400 kg of depleted uranium as trim weight in the tail, a fact unknown during the recovery effort.
