Narrative:

Lax helicopter control cleared helicopter X for takeoff from the kikroy bldg roof, (1/4 mi south of lax) SVFR industrial route south; to contact hawthorne tower at xerox. I held in right turns over xerox; received the SVFR clearance via the industrial/artesia rtes. I proceeded southbound. Haw tower reported 12 O'clock traffic, altitude unknown. The WX worsened to 500' 1 mi or less (reported was 800'/3 mi). At trw a helicopter Y appeared out of the ragged bases at 12 O'clock. Both aircraft broke right. The helicopter Y passed off my port side as close at 100-200'. At the time I was well inside the lax control zone. I advised both haw and lax towers of the 'near miss'. In a later telephone conversation with FAA supervisor lax tower, he advised me that a helicopter Y called in from the south for the industrial route just after I reported the 'near miss'. How do you protect yourself when in assigned airspace and someone attempt to occupy it lso. If the helicopter Y was squawking mode C hawthorne could have given me a vector, but hawthorne doesn't have altitude reporting radar. The reported traffic was typical of the higher level 'lax corridor' traffic. If lax still had control of me, it might have been prevented. There seems to be a 'weak' area of control on the industrial and artesia rtes, and a review of procedures and coordination techniques is in order.

Title: HELICOPTER Y ENTERED LAX TCA WITHOUT ATC CLRNC HAD NMAC WITH HELICOPTER X. PLTDEV.

Narrative: LAX HELI CTL CLRED HELI X FOR TKOF FROM THE KIKROY BLDG ROOF, (1/4 MI S OF LAX) SVFR INDUSTRIAL RTE S; TO CONTACT HAWTHORNE TWR AT XEROX. I HELD IN R TURNS OVER XEROX; RECEIVED THE SVFR CLRNC VIA THE INDUSTRIAL/ARTESIA RTES. I PROCEEDED SBND. HAW TWR RPTED 12 O'CLOCK TFC, ALT UNKNOWN. THE WX WORSENED TO 500' 1 MI OR LESS (RPTED WAS 800'/3 MI). AT TRW A HELI Y APPEARED OUT OF THE RAGGED BASES AT 12 O'CLOCK. BOTH ACFT BROKE R. THE HELI Y PASSED OFF MY PORT SIDE AS CLOSE AT 100-200'. AT THE TIME I WAS WELL INSIDE THE LAX CTL ZONE. I ADVISED BOTH HAW AND LAX TWRS OF THE 'NEAR MISS'. IN A LATER TELEPHONE CONVERSATION WITH FAA SUPVR LAX TWR, HE ADVISED ME THAT A HELI Y CALLED IN FROM THE S FOR THE INDUSTRIAL RTE JUST AFTER I RPTED THE 'NEAR MISS'. HOW DO YOU PROTECT YOURSELF WHEN IN ASSIGNED AIRSPACE AND SOMEONE ATTEMPT TO OCCUPY IT LSO. IF THE HELI Y WAS SQUAWKING MODE C HAWTHORNE COULD HAVE GIVEN ME A VECTOR, BUT HAWTHORNE DOESN'T HAVE ALT RPTING RADAR. THE RPTED TFC WAS TYPICAL OF THE HIGHER LEVEL 'LAX CORRIDOR' TFC. IF LAX STILL HAD CTL OF ME, IT MIGHT HAVE BEEN PREVENTED. THERE SEEMS TO BE A 'WEAK' AREA OF CTL ON THE INDUSTRIAL AND ARTESIA RTES, AND A REVIEW OF PROCS AND COORD TECHNIQUES IS IN ORDER.
