Location: 1 km from Juara Airport, MT (JUA) –
ÿ Brazil
Phase of Flight: Approach
Status: Destroyed, written off
Casualties: Fatalities: 17 / Occupants: 17
Component Affected: Fuel injection nozzle and compressor turbine vane ring.Fuel injection nozzle and compressor turbine vane ring.
Category: Accident
A Bandeirante aircraft experienced a significant engine failure during a takeoff, resulting in a stall and subsequent crash. A faulty fuel injection nozzle caused a blow torch effect, leading to compressor turbine vane ring damage and thermal fatigue. This imbalance ruptured the starting control bypass fuel return, ultimately causing the engine to stall and crash 1 km short of the runway.A Bandeirante aircraft experienced a significant engine failure during a takeoff, resulting in a stall and subsequent crash.

Description
A no. 1 engine faulty fuel injection nozzle caused a blow torch effect, damaging compressor turbine vane ring and causing thermal fatigue and loss of one of the turbine blades. The resulting imbalance ruptured the starting control bypass fuel return. The engine was shut down and an emergency landing attempted on a nearby runway. The Bandeirante stalled however and crashed 1 km short of the runway.
Primary Cause
