NINE MEMBERS OF A VARSITY BASKETBALL TEAM BOARDED THE ACFT W/O THE PLT GETTING ACCURATE PASSENGER WEIGHTS & THE BAGGAGE WAS PLACED IN THE AFT BAGGAGE COMPARTMENT. AS THE PLT ENTERED THE CABIN & WAS CLOSING THE DOOR, THE TAIL OF THE ACFT FELL HARD TO THE RAMP. THE PLT RAISED THE TAIL & ELECTED TO CONT THE FLT. AFTER REBOARDING, HE TAXIED TO THE RUNWAY & BEGAN THE TAKEOFF. AS THE ACFT WAS CLIMBING THRU APRX 200 TO 400 FT AGL, THE PLT ANNOUNCED THERE WAS A PROBLEM & ASKED THE PASSENGERS TO MOVE FORWARD. AT THAT TIME, THE NOSE OF THE ACFT WAS HIGHER THAN NORMAL & THE STALL WARNING HORN SOUNDED. THE PASSENGERS MOVED AS FAR FORWARD AS FEASIBLE & STAYED THERE UNTIL AFTER THE ACFT WAS LANDED. A POST-FLT EXAM OF THE ACFT REVEALED A STRINGER, REAR BULKHEAD, ELEVATOR CONTROL TUBE & THE HOUSING FOR THE TAIL NAVIGATION LIGHT WERE DAMAGED. NO BALLAST WAS INSTALLED IN THE FORWARD BAGGAGE COMPARTMENT. A RECALCULATION OF THE AIRCRAFT'S WEIGHT & BALANCE, USING THE ACTUAL WEIGHTS OF THE PASSENGERS, REVEALED THE CENTER-OF-GRAVITY (CG) WAS BEHIND THE AFT LIMIT.
Probable Cause: INADEQUATE PREFLIGHT PLANNING AND PREPARATION BY THE PILOT WHICH RESULTED IN IMPROPER WEIGHT AND BALANCE (AFT CG). THE AFT CG ALSO CONTRIBUTED TO THE UNCOMMANDED ALTITUDE DEVIATION AFTER TAKEOFF.
