Narrative:

Upon takeoff roll at rotation (90 KTS) binding was discovered in the elevator controls. Aircraft was brought to stop using full length of runway 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 flight control check had been performed prior to taxi. Company maintenance was notified and the VOR gauge removed prior to ferry to maintenance headquarters for further work. The incident can be prevented with regular insertions of aircraft panel and support screws supporting the aircraft's gauges to ensure that they remain in place. Callback conversation with reporter revealed the following information: the reporter stated that the preflight control check was normal. It is his observation that the VOR indicator and tuning head slid forward and dropped in a position that precluded elevator inputs behind the instrument panel. The company reported that the mounting screws had sheared allowing the unit to drop free of the bracket. The forward movement jammed the elevator linkage. The aircraft was stopped using every ft of 2700 ft runway at lup.

Title: 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.
