Collided with a Piper PA-28-181 Archer owned by Air Pegasus (N1977H). The Falcon was on a VOR/DME-A approach to Teterboro and crashed into an apartment building. Primary causes were inadequate coordination among ATC controllers and a misleading advisory to the Falcon on the Pa-28 heading.

Probable Cause:

PROBABLE CAUSE: "A breakdown in air traffic control coordination which resulted in an air traffic conflict and the inability of the DA50 flightcrew to ‘see and avoid' the other aircraft due to (1) an erroneous and inadequate traffic advisory and (2) the physiological limitations of human vision and reaction time at night. Air traffic control management contributed to the accident by failing to insure that controllers were following prescribed procedures and by failing to recognize and correct operational deficiencies."
