A C402 FLC HAD A VOR INDICATOR AND TUNING HEAD DISLODGE; BLOCKING THE ELEVATOR CTL ON TKOF ROLL AT LUP.

Narrative

UPON TKOF ROLL AT ROTATION (90 KTS) BINDING WAS DISCOVERED IN THE ELEVATOR CTLS. ACFT WAS BROUGHT TO STOP USING FULL LENGTH OF RWY AND BLAST AREA. INVESTIGATION DISCOVERED THAT THE #1 VOR GAUGE HAD FALLEN THROUGH THE BACK OF THE PANEL AND BLOCKED AFT MOVEMENT OF THE YOKE. A FLT CTL CHK HAD BEEN PERFORMED PRIOR TO TAXI. COMPANY MAINT WAS NOTIFIED AND THE VOR GAUGE REMOVED PRIOR TO FERRY TO MAINT HEADQUARTERS FOR FURTHER WORK. THE INCIDENT CAN BE PREVENTED WITH REGULAR INSERTIONS OF ACFT PANEL AND SUPPORT SCREWS SUPPORTING THE ACFT'S GAUGES TO ENSURE THAT THEY REMAIN IN PLACE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE PREFLT CTL CHK WAS NORMAL. IT IS HIS OBSERVATION THAT THE VOR INDICATOR AND TUNING HEAD SLID FORWARD AND DROPPED IN A POS THAT PRECLUDED ELEVATOR INPUTS BEHIND THE INST PANEL. THE COMPANY RPTED THAT THE MOUNTING SCREWS HAD SHEARED ALLOWING THE UNIT TO DROP FREE OF THE BRACKET. THE FORWARD MOVEMENT JAMMED THE ELEVATOR LINKAGE. THE ACFT WAS STOPPED USING EVERY FT OF 2700 FT RWY AT LUP.
