Narrative:

I was on an IFR cross country to melbourne; fl. I was 15 mins away from the end of a 2 hour flight above a broken layer. I had previously been in contact with ZJX; then mco approach. All radio contacts consisted of nothing more than an altimeter setting; and later with a frequency change. According to my VOR indications; I was centered on V3 (161 degree radial from omn) and steering 165 degrees magnetic. Mco approach directed that I contact daytona approach and said good-day. After rechking my altitude and position; I changed frequency and called daytona approach. The controller first said; 'descend and maintain 4000 ft.' before I responded with confirmation; the controller asked for my present heading. I replied 165 degrees; and he responded; 'turn right to heading of 180 degrees.' at about this time I looked down through a broken layer; and saw the shuttle landing facility off my left wing; and estimated that I had strayed into R2934. With alarm; I reconfirmed that my instruments showed me on course. It then suddenly occurred to me that on a previous flight in the same area; in a different aircraft; I was also called by approach; and asked to correct my heading to the west. On that previous occasion; I remember telling the controller that my VOR showed a centered needle even though he saw me 4 mi off course. At that previous time; that controller said; 'yeah; there is a problem right there in that area; right about at the change-over point.' callback conversation with reporter revealed the following information: the reporter stated that prior to this flight he checked the accuracy of the vors. #1 VOR was accurate while #2 VOR was 5 degrees off at takeoff and so he was not using that radio. He experienced a similar event in may flying a different aircraft but did not stray completely into the restr airspace. The controller while talking with him about this incursion sounded conciliatory while he explained that ATC had a problem with that airway in the vicinity of malet. He has heard nothing from the FAA about this event.

Title: A C172 PLT ON V3 CTRLINE RPTS ENTERING R2934 (SHUTTLE LNDG SITE) AND ATC STATING A KNOWN PROB WITH THE AIRWAY.

Narrative: I WAS ON AN IFR XCOUNTRY TO MELBOURNE; FL. I WAS 15 MINS AWAY FROM THE END OF A 2 HR FLT ABOVE A BROKEN LAYER. I HAD PREVIOUSLY BEEN IN CONTACT WITH ZJX; THEN MCO APCH. ALL RADIO CONTACTS CONSISTED OF NOTHING MORE THAN AN ALTIMETER SETTING; AND LATER WITH A FREQ CHANGE. ACCORDING TO MY VOR INDICATIONS; I WAS CTRED ON V3 (161 DEG RADIAL FROM OMN) AND STEERING 165 DEGS MAGNETIC. MCO APCH DIRECTED THAT I CONTACT DAYTONA APCH AND SAID GOOD-DAY. AFTER RECHKING MY ALT AND POS; I CHANGED FREQ AND CALLED DAYTONA APCH. THE CTLR FIRST SAID; 'DSND AND MAINTAIN 4000 FT.' BEFORE I RESPONDED WITH CONFIRMATION; THE CTLR ASKED FOR MY PRESENT HDG. I REPLIED 165 DEGS; AND HE RESPONDED; 'TURN R TO HDG OF 180 DEGS.' AT ABOUT THIS TIME I LOOKED DOWN THROUGH A BROKEN LAYER; AND SAW THE SHUTTLE LNDG FACILITY OFF MY L WING; AND ESTIMATED THAT I HAD STRAYED INTO R2934. WITH ALARM; I RECONFIRMED THAT MY INSTS SHOWED ME ON COURSE. IT THEN SUDDENLY OCCURRED TO ME THAT ON A PREVIOUS FLT IN THE SAME AREA; IN A DIFFERENT ACFT; I WAS ALSO CALLED BY APCH; AND ASKED TO CORRECT MY HDG TO THE W. ON THAT PREVIOUS OCCASION; I REMEMBER TELLING THE CTLR THAT MY VOR SHOWED A CTRED NEEDLE EVEN THOUGH HE SAW ME 4 MI OFF COURSE. AT THAT PREVIOUS TIME; THAT CTLR SAID; 'YEAH; THERE IS A PROB RIGHT THERE IN THAT AREA; RIGHT ABOUT AT THE CHANGE-OVER POINT.' CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT PRIOR TO THIS FLT HE CHKED THE ACCURACY OF THE VORS. #1 VOR WAS ACCURATE WHILE #2 VOR WAS 5 DEGS OFF AT TKOF AND SO HE WAS NOT USING THAT RADIO. HE EXPERIENCED A SIMILAR EVENT IN MAY FLYING A DIFFERENT ACFT BUT DID NOT STRAY COMPLETELY INTO THE RESTR AIRSPACE. THE CTLR WHILE TALKING WITH HIM ABOUT THIS INCURSION SOUNDED CONCILIATORY WHILE HE EXPLAINED THAT ATC HAD A PROB WITH THAT AIRWAY IN THE VICINITY OF MALET. HE HAS HEARD NOTHING FROM THE FAA ABOUT THIS EVENT.
