The accident aircraft was Fokker F.VIII H-NADU, c/n 4993. The aircraft was manufactured in 1926 and had entered service with KLM on 24 June 1927.[1]


On 22 August 1927, H-NADU departed Croydon at 8:07 am,[1] bound for Rotterdam.[2] it was carrying two crew, nine passengers, 13 kilograms (29 lb) of mail and 144 kilograms (317 lb) of freight. About 10 minutes after take-off, a tensioning wire at the tail broke, tearing off the rudder and tailfin. This made the aircraft very difficult to control, with a crash inevitable.[1] The aircraft crashed into the crowns of some trees in the grounds of a large house named St Julian's at Underriver.[3] The mechanic was killed when he was crushed by one of the engines.[4] The pilot and seven passengers were injured.[1] The tailfin and rudder were recovered at a distance of over 1 kilometre (1,100 yd) from the wreckage of the aircraft. Damage to the aircraft was assessed at ƒ68,985.07.[2]
