Factual narrative

THE ACFT ROLLED TO THE RIGHT AND CRASHED AFTER A CATASTROPHIC (UNCONTAINED) FAILURE OF THE RT ENG DURING TAKEOFF FOR A NIGHT FLT. THE RT ENG FAN ROTOR DISC SEPARATED FROM THE HUB WHICH DAMAGED THE COWLING AND SOME DISC FRAGMENTS BURIED IN THE FUSELAGE BUT WITHOUT DAMAGE TO THE FLT CONTROLS. THE DRAG CREATED BY THE LOSS OF THRUST AND THE DISTORTED COWLING LED TO YAW AND ROLL WITH LOSS OF CONTROL OF THE ACFT. THE FAN FAILURE PROPAGATED FROM A LOW GRADE FATIGUE CRACK ON THE HIGH TIME FAN WHICH WAS NOT DETECTED BY THE VISUAL INSPECTION PROCEDURES EXISTING AT THE TIME. THE MAUNUFACTURER HAS SINCE IMPROVED THE MANUFACTURING AND INSPECTION TECHNIQUES. AN AD 86-04-02 WAS ISSUED ON 2/14/86 WHICH DEALS WITH FAN REMOVAL FROM SERVICE ACCORDING TO AN OPERATING CYCLE SCHEDULE.
