Boeing 747-400SF, B-HKH

Summary:

The flaps were slow to retract when the crew selected them after landing. Subsequent inspection revealed damage to panels surrounding the inboard flaps on the right wing and that the outboard end fitting of the right wing landing gear support beam had failed. The manufacturer was aware of the potential for water ingress behind the main bushing in the end fitting to lead to corrosion, and subsequent cracking, and had issued an Alert Service Bulletin in November 2009 detailing inspection requirements and remedial actions.
