On 17 December 1960, a Convair C-131D Samaritan operated by the United States Air Force on a flight from Munich to RAF Northolt crashed shortly after take-off from Munich-Riem Airport, due to fuel contamination. All 20 passengers and crew on board as well as 32 people on the ground were killed. Accident On 17 December 1960, the Samaritan was due to fly from Munich-Riem airport in Germany to RAF Northolt in the United Kingdom with 13 passengers and 7 crew. Shortly after takeoff, the aircraft lost power to one of its two Pratt & Whitney R-2800 radial engines. Unable to maintain altitude and with bad visibility due to fog, it hit the steeple of St. Paul's Church next to the Oktoberfest site (then vacant) in the Ludwigsvorstadt borough. Subsequently, at 2:10 PM, it crashed into a crowded two-section Munich tramway car on Martin-Greif-Straße, close to Bayerstraße. All 13 passengers and 7 crew members on the plane died. 32 people on the ground were killed and 20 were injured. A section of the wing crashed through the roof of a building at Hermann-Lingg-Straße, a block away from the main accident site, without injuring anybody there. The Free Lance-Star, a daily newspaper for Fredricksburg and its surrounding areas, reported that some passengers on the Convair were holiday-bound University of Maryland students who were dependants of military personnel stationed in England. Aircraft The accident aircraft, Convair C-131D-CO Samaritan, (c/n 212, company designation: Model 340-79), was a twin piston engined military transport with seating for 44 passengers. Given the military serial number 55-0291, the aircraft was the first United States Air Force C-131 to be based in Europe, at RAF Northolt, where it was under command of the 7500th Air Base Group, 3rd Air Force, U.S. Air Forces in Europe (USAFE). Investigation A crash investigation revealed water in the fuel tank booster pump. Because water is more dense than fuel it can settle to the bottom of the tank, into the pump inlets; when it freezes it blocks inlets and deprives the engine of fuel. This deprivation of fuel caused the Munich C-131 to lose power and eventually shut down the engine. Aftermath After the accident, the Munich Fire & Rescue Services ordered new TLF 16 powder trucks to complement their fleet of traditional water tenders. Munich had initiated the expansion plans for Munich-Riem Airport in 1954. However, two plane crashes within the Munich
