Aircraft Involved:
• Aircraft Type: Boeing 777-300
• Registration: PH-BVS
• Operator: KLM Royal Dutch Airlines
• Flight Number: KL-835
• Route: Amsterdam (Netherlands) to Singapore (Singapore)
Incident Overview
A KLM Boeing 777-300, operating flight KL-835 from Amsterdam to Singapore, encountered a hydraulic system failure while cruising at FL290. The crew elected to return to Amsterdam Schiphol Airport. The incident required the use of alternate gear and flap extension systems and prompted a controlled fuel dump to reduce landing weight. The aircraft landed safely on runway 27 about 90 minutes after departure.
Sequence of Events
1. Departure:
• The flight departed Amsterdam Schiphol (AMS) as scheduled, heading to Singapore.
2. Enroute Hydraulic Failure:
• While cruising at FL290, the crew identified a hydraulic system failure. This system issue rendered standard gear and flap operation unavailable.
3. Decision to Return:
• The crew declared an emergency and decided to return to Schiphol for safety reasons.
• The aircraft performed a fuel dump to achieve a safe landing weight.
4. Landing:
• Using alternate gear and flap extension procedures, the crew executed a controlled and safe landing on runway 27.
• The aircraft required a tow truck after landing due to the hydraulic failure’s impact on normal taxiing capabilities.
5. Impact on Operations:
• The full rotation of KL-835 (AMS-SIN-DPS-SIN-AMS) was cancelled, impacting passengers on subsequent legs.
Initial Findings and Hypotheses
1. Hydraulic System Malfunction:
• The failure likely stemmed from a critical component in the hydraulic system, which affected gear, flaps, and other related systems.
2. Crew Response:
• The crew followed standard operating procedures, demonstrating professionalism in managing the emergency and ensuring passenger safety.
3. Aircraft Maintenance:
• The aircraft remained on the ground at Schiphol for over 23 hours for inspection and repair.
Analysis and Recommendations
1. Hydraulic System Inspection:
• Conduct a detailed inspection of the hydraulic system to determine the root cause of the failure.
2. Maintenance Protocol Review:
• Review recent maintenance records to identify any missed signs of potential hydraulic issues.
3. Crew Training:
• Reinforce alternate landing gear and flap extension procedures during crew training to maintain high standards of emergency response.
4. Passenger Communication:
• Enhance communication with affected passengers to ensure their concerns are addressed promptly and rebooking options are efficiently handled.
