Accidents & Serious Incidents involving WW24

  • WW24, vicinity John Wayne Airport Santa Ana CA USA, 1993 (On 15 December 1993, the crew of an IAI Westwind on a domestic passenger charter flight failed to leave sufficient separation between their aircraft and the Boeing 757 ahead on finals in night VMC and lost control or their aircraft which crashed killing all occupants and destroying the aircraft in the impact and post-crash fire.)
  • WW24, vicinity Norfolk Island South Pacific, 2009 (On 18 November 2009, an IAI Westwind on a medevac mission failed to make a planned night landing at Norfolk Island in unanticipated adverse weather and was intentionally ditched offshore because of insufficient fuel to reach the nearest alternate. The fuselage broke in two on water contact but all six occupants escaped from the rapidly sinking wreckage and were eventually rescued. The Investigation initially completed in 2012 was reopened after concerns about its conduct and a new Final Report in 2017 confirmed that the direct cause was flawed crew decision-making but also highlighted ineffective regulatory oversight and inadequate Operator procedures.)
