Small aircraft X was in a practice VOR DME a into teb. Subject aircraft was transmitting a discrete code assigned by ny TRACON, and maintaining VFR. Small aircraft X was inbound on the teb 305 degree right, approximately 1-1.5 mi inside clifo intersection at an altitude of 1000' MSL. The other aircraft, small aircraft Y, had just departed off runway 24 at teb. Small aircraft Y apparently made a left turn out, and then proceeded nwbnd on the teb 305 degree right. The safety pilot in small aircraft X observed the small aircraft Y traffic climbing, headed directly toward small aircraft X. He immediately alerted the PIC, who made an immediate accelerated descent. Small aircraft Y passed overhead, with a vertical sep of approximately 200-300'. Note: during the period of time the VOR DME a pahc is being used at teb, departing VFR aircraft should be alerted to avoid the teterboro 305 degree right.

Title: CLOSE PROX 2 GA-SMA ACFT IN TEB ATA.
Narrative: SMA X WAS IN A PRACTICE VOR DME A INTO TEB. SUBJECT ACFT WAS XMITTING A DISCRETE CODE ASSIGNED BY NY TRACON, AND MAINTAINING VFR. SMA X WAS INBND ON THE TEB 305 DEG R, APPROX 1-1.5 MI INSIDE CLIFO INTXN AT AN ALT OF 1000' MSL. THE OTHER ACFT, SMA Y, HAD JUST DEPARTED OFF RWY 24 AT TEB. SMA Y APPARENTLY MADE A LEFT TURN OUT, AND THEN PROCEEDED NWBND ON THE TEB 305 DEG R. THE SAFETY PLT IN SMA X OBSERVED THE SMA Y TFC CLBING, HEADED DIRECTLY TOWARD SMA X. HE IMMEDIATELY ALERTED THE PIC, WHO MADE AN IMMEDIATE ACCELERATED DSCNT. SMA Y PASSED OVERHEAD, WITH A VERT SEP OF APPROX 200-300'. NOTE: DURING THE PERIOD OF TIME THE VOR DME A PAHC IS BEING USED AT TEB, DEPARTING VFR ACFT SHOULD BE ALERTED TO AVOID THE TETERBORO 305 DEG R.
