Investigation Summary
The accident sequence began during a night approach in heavy rain and wind shear. The crew failed to maintain a stable glide path, resulting in a hard landing where the nose gear struck the runway first. The aircraft bounced three times, causing critical damage to the landing gear, hydraulic systems, and flight control surfaces. During the subsequent go-around, the crew reported that the yoke felt 'light' and had 'lost control,' and the Flight Engineer noted that the airspeed indicator had failed. A significant CRM breakdown occurred when the First Officer repeatedly suggested turning around to land immediately, but the Captain insisted on climbing to 1,200 meters first despite the severely compromised airframe. On the second landing attempt, the aircraft descended at an excessive sink rate. The First Officer repeatedly warned of the high sink rate and speed, but the damaged airframe could not be flared effectively, leading to a catastrophic high-speed impact.
Final Conclusions
The investigation attributed the crash to pilot error aggravated by severe weather. The crew failed to execute a go-around during the initial unstable approach and subsequently mishandled the aircraft after it sustained heavy damage during the first landing attempt. The decision to continue the second approach with a severely compromised airframe and failing flight controls, rather than seeking a more stable configuration or alternative emergency procedures, led to the final loss of control.

Systems & Failure Modes
Landing Gear
Sustained critical damage during the first landing attempt, preventing retraction and contributing to aerodynamic instability.
Hydraulic System
The EFIS master warning indicated hydraulic failure following the initial hard landing, leading to a loss of flight control effectiveness.
GPWS
The Ground Proximity Warning System issued multiple 'GLIDE SLOPE', 'WIND SHEAR', and 'SINK RATE' alerts during both landing attempts.

Leaked Cockpit Voice Recording
Reference ↗In June 2007, a 12-minute audio recording purported to be the final moments of Flight 3456 was leaked on the internet. While the CAAC noted it was unlikely to be fake, the leak of such sensitive data caused significant public discussion regarding the crew's final actions and the intensity of the cockpit environment.
