Template:Short description Script error: No such module "Unsubst". Script error: No such module "Infobox".Script error: No such module "Check for unknown parameters". NLM CityHopper Flight 431 refers to a Fokker F-28-4000, registration PH-CHI, that was due to operate an international scheduled Rotterdam–Eindhoven–Hamburg passenger service. On 6 October 1981, the aircraft encountered a tornado on the first leg, minutes after taking off from Rotterdam Airport, and crashed Script error: No such module "convert". south-southeast of Rotterdam. All 17 occupants of the aircraft – 13 passengers and 4 crew members– died in the accident.[1]Template:Rp[2]
Aircraft and crew
The aircraft involved in the accident was a Fokker F28-4000, registration PH-CHI, that was built in 1979 with c/n 11141. At the time of the accident, the airframe had accumulated 4,485 flight hours and 5,997 cycles.[2]
The captain was 33-year-old Jozef Werner, who had been with NLM CityHopper for nearly 11 years. He had 4,900 flight hours, including 309 hours on the Fokker F28. The first officer was 28-year-old Hendrik Schoorl, who had been with the airline for three years and had 2,971 flight hours, with 2,688 of them on the Fokker F28.[3]
Description of the accident
During the weather briefing 44 minutes before takeoff, the crew was apprised to an area of strong thunderstorms with 3/8 (37.5%) sky coverage of cumulonimbus at a base of Script error: No such module "convert"., south-southwest winds Script error: No such module "convert". strong, and Script error: No such module "convert". visibility at Rotterdam Airport (Template:Comma separated entries).[2] The aircraft took off at 17:04 CET (UTC +1) from RTM.[2] The crew noted heavy rain in thunderstorms on the airplane's weather avoidance radar at 17:09, receiving clearance to avoid the area.[2] At 17:12 the aircraft entered a tornado while flying through clouds.[2] The weather system the aircraft entered into was apparently the same "tornado-like" system that Zeeland locals described as being responsible for considerable property damage.[4] Meteorologically, these vortices are indeed tornadoes, and the disintegrating airliner was seen exiting cloud cover. A police officer first photographed the tornado, then smoke from the burning plane a few minutes later. An investigation concluded that a sharp increase in altitude registered on the altimeter was not a change in altitude, rather a pressure drop associated with the tornado.[5][6]
Stresses experienced by the airframe owing to severe turbulence[7] resulted in loads of +6.8 g and −3.2 g causing the starboard wing to detach.[2][8] The aircraft was designed for a maximum G-load of up to 4 g.[7] The aircraft spun down into the ground from Script error: No such module "convert"., crashing some Script error: No such module "convert". from a Shell chemical plant on the southeastern outskirts of Moerdijk.[4] All 17 occupants of the aircraft perished in the accident.[2] While observing the unfolding incident from the ground, a firefighter suffered a fatal cardiac arrest.[3]
