Aircraft involved
Probable cause & findings
Incorrect lubrication of the foreflap fitting assembly.
Factual narrative
The flight crew reported that upon arrival at KMIA, another flight reported seeing something fly off their airplane. Post-flight inspection revealed damage to the right-hand inboard flaps, fuselage and right horizontal stabilizer. Upon lowering flaps, a section of the trailing edge flap was also missing. Examination of the damaged components revealed that the right inboard foreflap fitting assembly had not been lubricated in accordance with a manufacturer’s service bulletin.
