Narrative:

An inbound pitts on tower frequency almost hits an outbound citation jet. The pitts just landed and the tower controller knowing he parked right across the taxiway, taxied him in without coording. I was working ground control at vny airport when citation jet called for taxi. I walked from my position across the cabin and saw he was parked at the base of the tower on the north side of the taxi corridor's centerline. I saw a pitts (that I recognized and was familiar with) taxiing from the runway opposite direction on centerline. The taxiway is wide so I taxied the citation to runway 34L and issued a caution for the pitts. A few seconds later after I had walked back to my normal position, the citation wanted to know where this 'asshole' in the pitts was going. I walked back over and saw that the citation had moved about 2 to 5 ft and stopped and the pitts was taxiing right in front of him. The pitts then slammed on his brakes and almost ended up on his propeller but then skillfully made an abrupt left turn and taxied to parking. The citation pilot was not happy and complained. Notes: tower controller is noted for taxiing in arrs without coording. I was familiar with the local controller taxiing in aircraft while working tower (especially if they parked close by) and keeping them on his frequency. When I saw the pitts taxiing, I assumed (correctly) that local controller had taxied him in. The taxi corridor is wide and aircraft pass there normally. Jets are towed to this area for engine starts as part of a noise abatement procedure. Propeller aircraft are exempt. Most jets are towed to either side to allow inbound or outbound aircraft access. The pitts was halfway across the taxiway and almost to the corridor side when I first saw him. He was on centerline and if he would have stayed, there should have been no problem to pass. The citation moved forward and slightly turned. From my perspective it allowed even more wingtip clearance.

Title: RPTED GND NEAR MISS WHEN PITTS ACFT INBOUND TO PARKING TAXIES IN CLOSE PROX TO A C500 OUTBOUND FROM PARKING. THE LCL CTLR DID NOT COORD THE PITTS NOR SWITCH IT TO GND CTL FREQ.

Narrative: AN INBOUND PITTS ON TWR FREQ ALMOST HITS AN OUTBOUND CITATION JET. THE PITTS JUST LANDED AND THE TWR CTLR KNOWING HE PARKED RIGHT ACROSS THE TXWY, TAXIED HIM IN WITHOUT COORDING. I WAS WORKING GND CTL AT VNY ARPT WHEN CITATION JET CALLED FOR TAXI. I WALKED FROM MY POS ACROSS THE CABIN AND SAW HE WAS PARKED AT THE BASE OF THE TWR ON THE N SIDE OF THE TAXI CORRIDOR'S CTRLINE. I SAW A PITTS (THAT I RECOGNIZED AND WAS FAMILIAR WITH) TAXIING FROM THE RWY OPPOSITE DIRECTION ON CTRLINE. THE TXWY IS WIDE SO I TAXIED THE CITATION TO RWY 34L AND ISSUED A CAUTION FOR THE PITTS. A FEW SECONDS LATER AFTER I HAD WALKED BACK TO MY NORMAL POS, THE CITATION WANTED TO KNOW WHERE THIS 'ASSHOLE' IN THE PITTS WAS GOING. I WALKED BACK OVER AND SAW THAT THE CITATION HAD MOVED ABOUT 2 TO 5 FT AND STOPPED AND THE PITTS WAS TAXIING RIGHT IN FRONT OF HIM. THE PITTS THEN SLAMMED ON HIS BRAKES AND ALMOST ENDED UP ON HIS PROP BUT THEN SKILLFULLY MADE AN ABRUPT L TURN AND TAXIED TO PARKING. THE CITATION PLT WAS NOT HAPPY AND COMPLAINED. NOTES: TWR CTLR IS NOTED FOR TAXIING IN ARRS WITHOUT COORDING. I WAS FAMILIAR WITH THE LCL CTLR TAXIING IN ACFT WHILE WORKING TWR (ESPECIALLY IF THEY PARKED CLOSE BY) AND KEEPING THEM ON HIS FREQ. WHEN I SAW THE PITTS TAXIING, I ASSUMED (CORRECTLY) THAT LCL CTLR HAD TAXIED HIM IN. THE TAXI CORRIDOR IS WIDE AND ACFT PASS THERE NORMALLY. JETS ARE TOWED TO THIS AREA FOR ENG STARTS AS PART OF A NOISE ABATEMENT PROC. PROP ACFT ARE EXEMPT. MOST JETS ARE TOWED TO EITHER SIDE TO ALLOW INBOUND OR OUTBOUND ACFT ACCESS. THE PITTS WAS HALFWAY ACROSS THE TXWY AND ALMOST TO THE CORRIDOR SIDE WHEN I FIRST SAW HIM. HE WAS ON CTRLINE AND IF HE WOULD HAVE STAYED, THERE SHOULD HAVE BEEN NO PROB TO PASS. THE CITATION MOVED FORWARD AND SLIGHTLY TURNED. FROM MY PERSPECTIVE IT ALLOWED EVEN MORE WINGTIP CLRNC.
