An MD88 first officer notes restricted throttle movement that is apparently caused by improper loading of luggage in the aft cargo compartment. The luggage appears to be pressing on the thin; easily-deformed compartment ceiling.

Narrative:
There have been 2 maintenance write-ups for jammed throttles over the last few weeks. Maintenance personnel discovered luggage in aft cargo bin jammed up against ceiling; causing ceiling to interfere with throttle linkage. Corrective action was to move luggage. One event was before takeoff; another event after landing! Boeing needs to investigate to develop long term corrective action. Poor design needs to be corrected as soon as possible.callback conversation with reporter revealed the following information: the reporter stated the forward and aft cargo compartment ceilings are made of a thin fiberglas material that is easily deformed by slight pressure. The procedure that is to be followed when loading the cargo compartment is no baggage to be located within 2 inches of the ceiling. The reporter noted that the baggage loading in many stations is contracted out and in many cases it appears that employees receive no training on airplane loading procedures.

Title: AN MD88 FO NOTES RESTRICTED THROTTLE MOVEMENT THAT IS APPARENTLY CAUSED BY IMPROPER LOADING OF LUGGAGE IN THE AFT CARGO COMPARTMENT. THE LUGGAGE APPEARS TO BE PRESSING ON THE THIN; EASILY-DEFORMED COMPARTMENT CEILING.
Narrative: THERE HAVE BEEN 2 MAINT WRITE-UPS FOR JAMMED THROTTLES OVER THE LAST FEW WEEKS. MAINT PERSONNEL DISCOVERED LUGGAGE IN AFT CARGO BIN JAMMED UP AGAINST CEILING; CAUSING CEILING TO INTERFERE WITH THROTTLE LINKAGE. CORRECTIVE ACTION WAS TO MOVE LUGGAGE. ONE EVENT WAS BEFORE TKOF; ANOTHER EVENT AFTER LNDG! BOEING NEEDS TO INVESTIGATE TO DEVELOP LONG TERM CORRECTIVE ACTION. POOR DESIGN NEEDS TO BE CORRECTED ASAP.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE FORWARD AND AFT CARGO COMPARTMENT CEILINGS ARE MADE OF A THIN FIBERGLAS MATERIAL THAT IS EASILY DEFORMED BY SLIGHT PRESSURE. THE PROC THAT IS TO BE FOLLOWED WHEN LOADING THE CARGO COMPARTMENT IS NO BAGGAGE TO BE LOCATED WITHIN 2 INCHES OF THE CEILING. THE RPTR NOTED THAT THE BAGGAGE LOADING IN MANY STATIONS IS CONTRACTED OUT AND IN MANY CASES IT APPEARS THAT EMPLOYEES RECEIVE NO TRAINING ON AIRPLANE LOADING PROCS.
