| Confidence Rating: |  Accident investigation report completed and information captured |
In flight the crew noticed that the hydraulic pressure decreased. Prior to landing at Arlanda, the landing gear and flaps were lowered by hand with the manual emergency system.
On landing the braking capability was limited and the nose wheel steering inoperative. No further damage occurred during landing. No person was injured during the incident
During the technical investigation that was carried out following the incident, it was established that hydraulic fluid had leaked through a fracture in a check valve for the right hydraulic pump. The conclusion of the investigation was that the valve had ruptured due to high cycle fatigue caused by vibrations.
The damaged clamps for the hydraulic pipe on which the check valve was mounted indicate that these might have had deficiencies. This circumstance has probably entailed that the pipe – and the connected valve – have been subjected to a higher vibration frequency than normal.
