Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Airframe/component/system failure/malfunction
Flt control syst,wing spoiler system - corrodedCause
Flt control syst,wing spoiler system - movement restrictedCause
Precautionary landing - performed
Analysis
The pilots were unable to retract the right wing spoilers after takeoff, so they returned to the departure airport for an uneventful landing. An inspection revealed rust & debris in the area of the bellcrank, which prevented the #1, #4 & #5 rgt hand spoilers from retracting. The spoilers remained extended 4 to 5 inches.
