SilkAir Flight 185 was a scheduled Boeing 737‑300 flight from Jakarta to Singapore that tragically crashed into the Musi River near Palembang on 19 December 1997, resulting in the loss of all 104 souls on board (97 passengers, 7 crew) .

Flight details & crash sequence

Departed Jakarta at 15:37 local time, crew included Captain Tsu Way Ming and First Officer Duncan Ward .

Reached cruising altitude FL350 (~35,000 ft) at 15:53. At 16:05 CVR stopped; at 16:11 FDR ceased .

At around 16:12, the aircraft entered a near-vertical dive, broke apart midair, and crashed supersonically into the Musi River within seconds .

Investigation & cause controversy

Indonesian NTSC

Found CVR/FDR stoppages puzzling but couldn’t identify a definitive cause—neither pilot action, mechanical failure, nor environmental factors conclusively .

US NTSB

Based on radar and forensic analysis, determined the dive was consistent with deliberate inputs by the captain, concluding pilot suicide as the likely cause .

California Superior Court ruling

Heard evidence suggesting a rudder power control unit servo valve failure, leading to an uncontrollable rudder hard-over; jury found this credible enough to absolve pilot intent .

Resulted in an out-of-court settlement with PCU manufacturer by victims’ families .

Why the differing conclusions?

CVR/FDR shutdown: Some suspect manual switch-off; NTSC kept an open mind but found no proof, while NTSB viewed it as intentional .

Radar & control analysis: NTSB simulations showed the rapid and unrecoverable dive could only be pilot-induced. California court considered mechanical failure plausible given servo valve evidence .

Pilot’s personal circumstances: NTSB noted Captain’s financial stress; NTSC dismissed this without concrete motive .

Legacy & media coverage

The crash remains one of Southeast Asia’s most debated, balancing between pilot suicide and mechanical failure theories .

The documentary SilkAir 185: Pilot Suicide? (2006, National Geographic Asia) explores both theories through interviews and reenactments .

Featured in episodes of Air Crash Investigation and Mayday: Air Disaster, highlighting the controversy .

In summary:

Theory Verdict

Indonesian NTSC undetermined cause

US NTSB pilot suicide likely

California court mechanical rudder failure credible

Ultimately, no single cause has been universally accepted, and the tragedy continues to be a subject of intense debate.
