| Description |
The normal hose assembly of LH undercarriage of an aircraft has failed by cracking at the ferrule edge of the end fittings connected to undercarriage main jack. Excessive bending stresses on the hose at this location appeared to be the most probable reason for such failure. After failure of the normal hose, the high-pressure oil jet impinged on the emergency hose (pt No.A20982-03) resulting in the damage of the reinforcements and the PTFE inner core. This has led to the failure of the emergency hose when it was operated. Therefore, failure of the emergency hose is secondary in nature and subsequent to the primary failure of the normal hose.
