Overview
On January 2nd, 2025, Jet2 flight LS-995, an Airbus A321-200N registered G-SUNJ, encountered a flaps problem while on approach to Las Palmas Airport (GCLP) in the Canary Islands. The aircraft, originating from Manchester, UK, was on its final approach when the crew identified a flaps malfunction and decided to abort the approach. Following standard procedures, the crew entered a holding pattern, performed the necessary checklists, and completed a safe landing on runway 03L with emergency services on standby.
No injuries or damage to the aircraft were reported.
Incident Summary
Flight Details
• Aircraft Type: Airbus A321-200N
• Registration: G-SUNJ
• Flight Number: LS-995
• Operator: Jet2.com
• Route: Manchester (EGCC) to Las Palmas (GCLP)
• Passengers and Crew: Unspecified
Sequence of Events
1. Final Approach: While descending towards runway 03L at Las Palmas, the crew identified a malfunction with the flap system.
2. Go-Around: The crew initiated a go-around and entered a holding pattern to troubleshoot the issue.
3. Checklist Execution: The crew executed the related abnormal procedures to address the flap problem and configured the aircraft for a safe landing.
4. Landing: The aircraft landed safely on runway 03L approximately 25 minutes after aborting the initial approach. Emergency services were on standby as a precaution.
Technical Analysis
Flap System Overview
The Airbus A321-200N is equipped with advanced trailing-edge flaps that enhance lift and allow for slower speeds during approach and landing. The flap system is hydraulically operated and monitored by the Flight Control Computers (FCCs).
Possible Causes of the Malfunction
1. Hydraulic System Issue:
• A leak, loss of hydraulic pressure, or actuator failure could have compromised flap deployment.
2. Electrical Fault:
• A fault in the Flap Control Units (FCUs) or wiring could result in improper flap position feedback or deployment.
3. Mechanical Failure:
• Jammed or misaligned flap tracks or slats might prevent full deployment.
4. Operational Limitation:
• Incorrect or conflicting data in the aircraft’s flight management system could have inhibited the flap extension.
Crew Actions
The crew’s decision to abort the approach, enter a hold, and perform checklists aligns with Airbus’ standard operating procedures. By configuring the aircraft for a landing without full flap deployment, they mitigated risks associated with higher approach and landing speeds.
Passenger Reports
Passengers reported that the crew announced a flap failure and explained the need to abort the approach. Despite the delay, passengers commended the clear communication from the flight deck and the safe landing.
Post-Incident Actions
1. Aircraft Inspection:
• The aircraft underwent maintenance inspections in Las Palmas to identify and rectify the cause of the flap problem.
2. Aircraft Return to Service:
• The aircraft resumed operations after approximately 2.5 hours on the ground, completing the return flight to Manchester (LS-996).
Recommendations
1. Maintenance Review:
• Conduct a thorough inspection of the flap hydraulic and electrical systems to identify potential faults.
• Evaluate maintenance logs for any recurring flap-related anomalies.
2. Crew Training:
• Reinforce training for abnormal flap scenarios, focusing on go-around and landing configurations.
3. Monitoring and Reporting:
• Ensure timely reporting of similar events to Airbus and regulatory authorities to identify patterns or systemic issues.
Conclusion
The flap malfunction on Jet2 flight LS-995 was managed effectively by the flight crew, ensuring the safety of all passengers and crew. The incident highlights the importance of robust standard operating procedures, thorough crew training, and proactive maintenance practices in mitigating in-flight anomalies.
