What happened
On the day of the accident, an Aero Commander 560E, registration N3827C, was performing an IFR flight from Blairstown to Teterboro Airport following minor maintenance work. The pilot was operating under instructions from New York TRACON, maintaining an altitude of 2,000 feet MSL on a radar vector for an ILS approach. While the aircraft's altitude-encoding transponder was active, air traffic controllers alerted the pilot to several other targets directly ahead.
Simultaneously, a Cessna 182Q, registration N96402, was traveling from Kupper Airport toward Ramapo Airport. This flight was being conducted under VFR without a filed flight plan or active radio contact with air traffic control. Although the aircraft had an operational transponder, it lacked altitude-encoding capabilities. As the two aircraft converged on a northeasterly heading, they collided approximately one mile inside the New York Terminal Control Area boundaries. Following the impact, both aircraft struck the ground roughly 1,500 feet apart. A map recovered from the Cessna 182Q showed a hand-drawn route intersecting the controlled airspace. The collision resulted in six fatalities, as all three occupants from both aircraft perished.
Findings
Investigations into the accident identified several contributing factors related to the operation of the Cessna 182Q. Key findings included a failure to maintain proper air/ground communications and a failure to follow established procedures or directives. Additionally, the pilot of the second aircraft failed to obtain necessary traffic advisories and did not identify hazardous conditions. The collision was primarily driven by inadequate visual lookout from both pilots involved in the incident.
