Narrative:

During climb out from burbank airport, cleared to 13000 ft and told to level at about 4800 ft for traffic. We did so and spotted high wing single engine aircraft doing air work at 12 O'clock slightly above our altitude. We descended to 4500 and passed under traffic, as he did steep turn, etc. After clear were again cleared to 13000 ft. Climbing through about 9000 ft TCASII mandated a descent for traffic above us at 12 O'clock. We followed the commands of the vertical speed indicator until issued appropriate TCASII indications at approximately 8000 ft. ATC said traffic was not a factor. We said we had to follow TCASII. We then resumed normal climb. Comments: how many deaths will it take to keep uncontrolled aircraft out of busy airspace such as this? I came from GA and firmly feel every aircraft in this type of airspace should be with ATC, assigned a code, have an encoding altimeter and preferably TCASII. Tell the AOPA lobby that the 'good old days are gone'! It's unsafe! Period!

Title: ACR MLG REVERSED CLB OUT FROM BUR IN RESPONSE TO TCASII TA.

Narrative: DURING CLB OUT FROM BURBANK ARPT, CLRED TO 13000 FT AND TOLD TO LEVEL AT ABOUT 4800 FT FOR TFC. WE DID SO AND SPOTTED HIGH WING SINGLE ENG ACFT DOING AIR WORK AT 12 O'CLOCK SLIGHTLY ABOVE OUR ALT. WE DSNDED TO 4500 AND PASSED UNDER TFC, AS HE DID STEEP TURN, ETC. AFTER CLR WERE AGAIN CLRED TO 13000 FT. CLBING THROUGH ABOUT 9000 FT TCASII MANDATED A DSCNT FOR TFC ABOVE US AT 12 O'CLOCK. WE FOLLOWED THE COMMANDS OF THE VERT SPD INDICATOR UNTIL ISSUED APPROPRIATE TCASII INDICATIONS AT APPROX 8000 FT. ATC SAID TFC WAS NOT A FACTOR. WE SAID WE HAD TO FOLLOW TCASII. WE THEN RESUMED NORMAL CLB. COMMENTS: HOW MANY DEATHS WILL IT TAKE TO KEEP UNCTLED ACFT OUT OF BUSY AIRSPACE SUCH AS THIS? I CAME FROM GA AND FIRMLY FEEL EVERY ACFT IN THIS TYPE OF AIRSPACE SHOULD BE WITH ATC, ASSIGNED A CODE, HAVE AN ENCODING ALTIMETER AND PREFERABLY TCASII. TELL THE AOPA LOBBY THAT THE 'GOOD OLD DAYS ARE GONE'! IT'S UNSAFE! PERIOD!
