Cargo aircraft ditching in Río San Carlos following engine failure

No fatalities • Boca San Carlos, Costa Rica • Flight

A cargo flight traveling from Managua to Panama City was forced to ditch in a river after an engine detachment and subsequent fire.

What happened

During a scheduled cargo transport operation flying from Managua toward Panama City, the aircraft experienced a severe mechanical failure while at cruising altitude. The number three engine became detached from the airframe, and a fire subsequently developed in the number four engine.

Although the crew successfully suppressed the fire, they were unable to feather the propeller of the affected engine. In an effort to manage the weight and stability of the aircraft, the occupants jettisoned the cargo. The flight eventually concluded with a controlled ditching in the Río San Carlos, specifically near the area of Boca San Carlos.

Findings

  • The incident resulted in six injuries among the occupants.
  • The aircraft was destroyed during the water landing.
  • The primary mechanical failure involved the separation of the number three engine and an engine fire.

Probable cause

The loss of the third engine and a subsequent fire in the fourth engine led to the emergency ditching.
