Incident Overview

Description
Aerolineas Argentinas flight 8524 was a scheduled flight from Buenos Aires to C¢rdoba and San Luis. The flight arrived at San Luis at 20:46. The landing was heavy, so the copilot asked the mechanic to check the undercarriage before departure. A quick turnaround for the flight back to Buenos Aires was performed. The aircraft taxied onto the runway towards the beginning of runway 18. While turning 180 degrees to line up for takeoff, the aircraft tires left signs of rubber marks. During the takeoff roll the no. 3 tire lost pressure and the no. 4 tire lost some thread. The no. 4 tire, on the right main gear, burst, just before reaching the V1 speed. Takeoff was aborted when the aircraft began vibrating and banked to the right. The aircraft overran by 125 m and caught fire. CAUSAS: “Aborto de despegue y despiste del avi¢n por la cabecera opuesta, provocando en principio da¤os en el mismo y posteriormente a la evacuaci¢n de los pasajeros su destrucci¢n total por el fuego, debido a la rotura de ambas cubiertas del tren de aterrizaje derecho durante la carrera iniciada.” FACTORES CONTRIBUYENTES: – Programaci¢n de vuelo con escalas de tiempo reducido y etapa corta en el tramo CBA – UIS que posiblemente no permiti¢ la necesaria refrigeraci¢n de las ruedas, dando origen al desinflado y posterior destrucci¢n del neum tico de la rueda 4 y la explosi¢n y destrucci¢n del neum tico de la rueda 3. – Disminuci¢n de la acci¢n de frenado en el conjunto del tren de aterrizaje con las cubiertas rotas; – Conocimiento parcial y desconocimiento de los tiempos y procedimientos para enfriamiento de las ruedas por parte de los pilotos; – Atraso en la salida del vuelo, respecto al horario programado; – Dificultad para apreciar en el aer¢dromo San Luis, durante operaciones nocturnas, referencias visuales de la pista recorrida y por recorrer y falta de inquietud de los pilotos durante el aborto del despegue (RTO); – Acci¢n poco eficaz de los medios contra incendio disponibles.
Primary Cause
The incident was likely caused by a combination of factors, including a premature tire failure and thread loss during the takeoff roll, exacerbated by a reduction in braking force on the landing gear, combined with a lack of proper wheel cooling and a failure to adequately assess and respond to the situation during the aborted takeoff and subsequent fire.The incident was likely caused by a combination of factors, including a premature tire failure and thread loss during the takeoff roll, exacerbated by a reduction in braking force on the landing gear, combined with a lack of proper wheel cooling and a failure to adequately assess and respond to the situation during the aborted takeoff and subsequent fire.Share on:
