Registration Number: N4465F
Location: Aruba-Reina Beatrix Airport (AUA) –
ÿ Aruba
Phase of Flight: En route
Status: Destroyed, written off
Casualties: Fatalities: 0 / Occupants: 3
Component Affected: Propeller gearbox (No. 3 & No. 4), No. 2 engine.Propeller gearbox (No. 3 & No. 4), No. 2 engine.
Category: Accident
A propeller gearbox failure on the No. 3 propeller resulted in the separation of the No. 4 propeller, causing further damage to the No. 2 engine. This incident occurred during an emergency landing at Aruba, with limited flight controls and braking.A propeller gearbox failure on the No. 3 propeller resulted in the separation of the No. 4 propeller, causing further damage to the No. 2 engine. This incident occurred during an emergency landing at Aruba, with limited flight controls and braking.
Description
The no. 3 propeller gearbox failed, causing the prop to separate. A broken propeller blade struck the no. 4 propeller, which also separated. A propeller then crossed under the aircraft slicing through the fuselage, cables, hydraulics and pressure vessel, damaging the no. 2 engine. The no. 2, 3 and 4 engines were shut down. An emergency landing was carried out at Aruba with no brakes, 10deg flaps and limited flight controls. PROBABLE CAUSE: “The in-flight loss of the nos 3 and 4 propellers and gearboxes for undetermined reasons. The failed components were not recovered from the Caribbean sea.”
Primary Cause
In-flight loss of the No. 3 and No. 4 propellers and gearbox components, potentially due to undetermined causes, leading to component failure and subsequent separation.In-flight loss of the No. 3 and No. 4 propellers and gearbox components, potentially due to undetermined causes, leading to component failure and subsequent separation.Share on:
