Narrative:

I was PF of a beech F33 bonanza. We were returning from psp en route to vny. We left psp VFR through the banning pass and picked up an IFR clearance. We were directed to pdz VOR (112.2) direct, then V186 to vny. Our altitude was 6000 ft MSL. About 12 mi west of paradise VOR we changed to vny VOR (113.1). Our HSI had been centered on the 278 degree radial of pdz. When vny VOR was selected and new course 275 degrees set on the HSI, the needle deflected left, indicating we were north of course, V186. I took a heading of 265 degrees (10 degree intercept) to reacquire V186. Several mins later the socal approach controller told me to turn to heading 300 degrees and intercept V186. He asked my heading and I replied 265 degrees. He said I was south of V186. I rechked D6 HSI and wet compass indications and they were ok. My indication showed I had corrected and was on V186 centerline. At about 20 mi east of vny the socal controller said turn heading 260 degrees and contact socal on 124.6 frequency. The PNF replied 'aircraft identify' and set 220 degrees in the heading bug of the HSI. I thought the controller said 220 degrees as well. At the time of the transmission, we were discussing why the HSI did not agree with socal's reported position of the aircraft. Only 1 VOR was available in the aircraft. The #2 system was in the shop for maintenance. Anyway, the other pilot failed to read back the appropriate heading of 260 degrees and we changed frequencys. Our first 2 calls to socal on 124.6 were not received, blocked. On our third call checking in 'with them, level at 6000 ft' we were instructed to turn to 300 degrees 'immediately.' we did and proceeded to fly the vny lda C approach uneventfully. On contacting vny ground control I was instructed to contact socal TRACON and given a phone number. I called and spoke to the operations supervisor. He said that I had flown into los angeles class B airspace and posed a potential conflict for lax traffic flow from the north. I told him of our HSI indications and that I flew 220 degree heading as instructed by the socal controller. He asked the controllers who said they never issued 220 degree heading. I reluctantly gave him my name and phone number. After listening to the tape, he called me at XA00 that evening and debriefed the event. We were told to turn 260 degrees and call socal. He confirmed a garbled radio transmission followed by our instruction to turn to 300 degrees. He also said there was some scalloping of the VOR signal in the vicinity of V186 where we were, but not enough to cause us to drift that far south. I said our HSI indicated we were north of V186 but he said our radar track never showed us north of course. I had no prior experience flying the lda C approach from that direction, so I assumed the 220 degree heading from socal was a vector to keep me south of bur's traffic flow.

Title: A BE33 BONANZA PLT EXPERIENCES A TRACK POS DEV AND INVADES THE LAX TCA CLASS B.

Narrative: I WAS PF OF A BEECH F33 BONANZA. WE WERE RETURNING FROM PSP ENRTE TO VNY. WE LEFT PSP VFR THROUGH THE BANNING PASS AND PICKED UP AN IFR CLRNC. WE WERE DIRECTED TO PDZ VOR (112.2) DIRECT, THEN V186 TO VNY. OUR ALT WAS 6000 FT MSL. ABOUT 12 MI W OF PARADISE VOR WE CHANGED TO VNY VOR (113.1). OUR HSI HAD BEEN CTRED ON THE 278 DEG RADIAL OF PDZ. WHEN VNY VOR WAS SELECTED AND NEW COURSE 275 DEGS SET ON THE HSI, THE NEEDLE DEFLECTED L, INDICATING WE WERE N OF COURSE, V186. I TOOK A HDG OF 265 DEGS (10 DEG INTERCEPT) TO REACQUIRE V186. SEVERAL MINS LATER THE SOCAL APCH CTLR TOLD ME TO TURN TO HDG 300 DEGS AND INTERCEPT V186. HE ASKED MY HDG AND I REPLIED 265 DEGS. HE SAID I WAS S OF V186. I RECHKED D6 HSI AND WET COMPASS INDICATIONS AND THEY WERE OK. MY INDICATION SHOWED I HAD CORRECTED AND WAS ON V186 CTRLINE. AT ABOUT 20 MI E OF VNY THE SOCAL CTLR SAID TURN HDG 260 DEGS AND CONTACT SOCAL ON 124.6 FREQ. THE PNF REPLIED 'ACFT IDENT' AND SET 220 DEGS IN THE HDG BUG OF THE HSI. I THOUGHT THE CTLR SAID 220 DEGS AS WELL. AT THE TIME OF THE XMISSION, WE WERE DISCUSSING WHY THE HSI DID NOT AGREE WITH SOCAL'S RPTED POS OF THE ACFT. ONLY 1 VOR WAS AVAILABLE IN THE ACFT. THE #2 SYS WAS IN THE SHOP FOR MAINT. ANYWAY, THE OTHER PLT FAILED TO READ BACK THE APPROPRIATE HDG OF 260 DEGS AND WE CHANGED FREQS. OUR FIRST 2 CALLS TO SOCAL ON 124.6 WERE NOT RECEIVED, BLOCKED. ON OUR THIRD CALL CHKING IN 'WITH THEM, LEVEL AT 6000 FT' WE WERE INSTRUCTED TO TURN TO 300 DEGS 'IMMEDIATELY.' WE DID AND PROCEEDED TO FLY THE VNY LDA C APCH UNEVENTFULLY. ON CONTACTING VNY GND CTL I WAS INSTRUCTED TO CONTACT SOCAL TRACON AND GIVEN A PHONE NUMBER. I CALLED AND SPOKE TO THE OPS SUPVR. HE SAID THAT I HAD FLOWN INTO LOS ANGELES CLASS B AIRSPACE AND POSED A POTENTIAL CONFLICT FOR LAX TFC FLOW FROM THE N. I TOLD HIM OF OUR HSI INDICATIONS AND THAT I FLEW 220 DEG HDG AS INSTRUCTED BY THE SOCAL CTLR. HE ASKED THE CTLRS WHO SAID THEY NEVER ISSUED 220 DEG HDG. I RELUCTANTLY GAVE HIM MY NAME AND PHONE NUMBER. AFTER LISTENING TO THE TAPE, HE CALLED ME AT XA00 THAT EVENING AND DEBRIEFED THE EVENT. WE WERE TOLD TO TURN 260 DEGS AND CALL SOCAL. HE CONFIRMED A GARBLED RADIO XMISSION FOLLOWED BY OUR INSTRUCTION TO TURN TO 300 DEGS. HE ALSO SAID THERE WAS SOME SCALLOPING OF THE VOR SIGNAL IN THE VICINITY OF V186 WHERE WE WERE, BUT NOT ENOUGH TO CAUSE US TO DRIFT THAT FAR S. I SAID OUR HSI INDICATED WE WERE N OF V186 BUT HE SAID OUR RADAR TRACK NEVER SHOWED US N OF COURSE. I HAD NO PRIOR EXPERIENCE FLYING THE LDA C APCH FROM THAT DIRECTION, SO I ASSUMED THE 220 DEG HDG FROM SOCAL WAS A VECTOR TO KEEP ME S OF BUR'S TFC FLOW.
