During aircraft startup, the right engine caught fire after the left engine was started. The pilot shut down both engines and evacuated passengers. Fire department extinguished the fire. Investigation revealed a ruptured fuel line and metal particles blocking the shut-off valve.

Incident Overview

During the startup sequence of the aircraft, the right engine began to burn. After the left engine was started, the pilot observed flames emanating from the top of the right engine. In response, the pilot initiated a shutdown of both engines and evacuated all passengers. The fire continued to burn until it was extinguished by the responding fire department.

Examination Findings

Post-incident examination of the right engine revealed a ruptured fuel line. Additionally, metal particles were found blocking the shut-off valve, which prevented the valve from closing properly. As a result, fuel continued to flow even after the engine shutdown was initiated, sustaining the fire until external suppression was applied.

Probable cause

A fuel line ruptured and metal particles blocked the shut-off valve, causing continued fuel flow and the fire.
