Aircraft impact during training approach at San Francisco Airport

No fatalities • San Francisco, United States of America • Landing (descent or approach)

A four-engine aircraft sustained heavy damage after impacting the runway surface during a local training flight at San Francisco International Airport.

What happened

During a scheduled transition training session at San Francisco Airport, a four-engine aircraft experienced a hard landing on the runway. The crew was performing a local training maneuver as part of an ongoing instructional program when the descent rate increased significantly during the final approach phase.

As the pilot-in-command attempted to execute the flare, the aircraft failed to arrest its downward momentum, resulting in a direct impact with the runway surface. The force of the collision caused the undercarriage to be sheared from the airframe. Following the impact, the aircraft slid across the pavement for a short distance before catching fire.

Findings

  • The crew successfully evacuated the aircraft during the emergency.
  • There were zero fatalities and zero injuries reported among the three crew members on board.
  • The aircraft sustained damage that rendered it beyond repair.

Probable cause

The aircraft impacted the runway due to an excessive rate of descent during the flare maneuver.
