Narrative:
A Fokker F28 Fellowship 4000, registered HC-CDT, sustained substantial during a runway excursion following an aborted takeoff from Quito-Mariscal Sucre Airport (UIO), Ecuador. All four crew members and 62 passengers survived the accident.
ICARO Flight 504 to Coca Airport (OCC) was cleared for takeoff from Quito (UIO) runway 35. During the takeoff roll the crew noted a fire alarm for the forward cargo hold and decided to abort the takeoff. The aircraft overran the end of runway 35, struck and destroyed the instrument landing system (ILS) aerials located 167 meters (550 ft) from the end of the runway, the existing security zone, and part of the airport's perimeter enclosure stopping 300 meters (985 feet) from the end of runway 35 after smashing through a brick wall.

La falta de aplicación del CRM durante el manejo de la emergencia.
La condición de humedad de la pista, que redujo considerablemente la eficacia del frenado.
