Narrative:

I was flying VFR-on-top with an IFR clearance to fly the VOR runway 30 approach into lgb. I was vectored, cleared for the approach, and told to descend to 1500 ft MSL IMC. Just before crossing the sci VOR, I was handed off from socal approach to lgb tower over top of sci VOR. I had full scale deflection of my CDI, I overcorrected and had to get back on course. Lgb tower inquired about my course, and I told them I was correcting. Shortly after that, lgb tower told me I was south of course and to go missed. There was a faster airplane behind me. My 80 KT speed was a factor as stated by ATC. I executed a missed approach at that point and turned to 200 degrees and climbed to 2500 ft MSL. I was later told I should have flown to the map and then executed the missed approach. Lgb tower was the controling agency that told me to go missed approach, and when I immediately turned and climbed, nothing was said to make me think I was in error. I now understand that socal approach was in control of another aircraft on the ILS runway 30 to lgb. We were 2 aircraft on 2 different approachs for the same runway at the same time, but controled by 2 different facilities. Although we never saw each other, when I was told to go missed, and did, my left climbing turn created a conflict with the traffic on the ILS. I thought I was correct to fly the missed approach when I did, because of my CDI having full scale deflection and lgb tower telling me to go missed. I do not think lgb tower was fully aware of other traffic in the area under the control of socal approach. I do, however, see where I may have been in error. I did what I thought was correct at that moment. I pride myself on being capable and proficient pilot and CFI.

Title: LOW TIME IFR RATED CFI IN C152 BECAME DISORIENTED WHILE PASSING OVER SLI ON VOR RWY 30 APCH TO LGB. EXCESSIVE CORRECTIONS TO GET BACK ON COURSE CAUSED A TFC CONFLICT TO DEVELOP WITH FASTER MOVING SECOND ACFT MAKING ILS RWY 30 APCH BEHIND HIM. SUBSEQUENT MISSED APCH WAS INITIATED PRIOR TO REACHING THE MISSED APCH POINT.

Narrative: I WAS FLYING VFR-ON-TOP WITH AN IFR CLRNC TO FLY THE VOR RWY 30 APCH INTO LGB. I WAS VECTORED, CLRED FOR THE APCH, AND TOLD TO DSND TO 1500 FT MSL IMC. JUST BEFORE XING THE SCI VOR, I WAS HANDED OFF FROM SOCAL APCH TO LGB TWR OVER TOP OF SCI VOR. I HAD FULL SCALE DEFLECTION OF MY CDI, I OVERCORRECTED AND HAD TO GET BACK ON COURSE. LGB TWR INQUIRED ABOUT MY COURSE, AND I TOLD THEM I WAS CORRECTING. SHORTLY AFTER THAT, LGB TWR TOLD ME I WAS S OF COURSE AND TO GO MISSED. THERE WAS A FASTER AIRPLANE BEHIND ME. MY 80 KT SPD WAS A FACTOR AS STATED BY ATC. I EXECUTED A MISSED APCH AT THAT POINT AND TURNED TO 200 DEGS AND CLBED TO 2500 FT MSL. I WAS LATER TOLD I SHOULD HAVE FLOWN TO THE MAP AND THEN EXECUTED THE MISSED APCH. LGB TWR WAS THE CTLING AGENCY THAT TOLD ME TO GO MISSED APCH, AND WHEN I IMMEDIATELY TURNED AND CLBED, NOTHING WAS SAID TO MAKE ME THINK I WAS IN ERROR. I NOW UNDERSTAND THAT SOCAL APCH WAS IN CTL OF ANOTHER ACFT ON THE ILS RWY 30 TO LGB. WE WERE 2 ACFT ON 2 DIFFERENT APCHS FOR THE SAME RWY AT THE SAME TIME, BUT CTLED BY 2 DIFFERENT FACILITIES. ALTHOUGH WE NEVER SAW EACH OTHER, WHEN I WAS TOLD TO GO MISSED, AND DID, MY L CLBING TURN CREATED A CONFLICT WITH THE TFC ON THE ILS. I THOUGHT I WAS CORRECT TO FLY THE MISSED APCH WHEN I DID, BECAUSE OF MY CDI HAVING FULL SCALE DEFLECTION AND LGB TWR TELLING ME TO GO MISSED. I DO NOT THINK LGB TWR WAS FULLY AWARE OF OTHER TFC IN THE AREA UNDER THE CTL OF SOCAL APCH. I DO, HOWEVER, SEE WHERE I MAY HAVE BEEN IN ERROR. I DID WHAT I THOUGHT WAS CORRECT AT THAT MOMENT. I PRIDE MYSELF ON BEING CAPABLE AND PROFICIENT PLT AND CFI.
