8 Aug 2009: PIPER PA-32R-300 (N71MC) — STEVEN M ALTMAN

9 fatalities • Hoboken, NJ, United States

Probable cause

(1) the inherent limitations of the see-and-avoid concept, which made it difficult for the airplane pilot to see the helicopter until the final seconds before the collision, and (2) the Teterboro Airport local controller’s nonpertinent telephone conversation, which distracted him from his air traffic control (ATC) duties, including correcting the airplane pilot’s read back of the Newark Liberty International Airport (EWR) tower frequency and the timely transfer of communications for the accident airplane to the EWR tower. Contributing to this accident were (1) both pilots’ ineffective use of available information from their aircraft’s electronic traffic advisory system to maintain awareness of nearby aircraft, (2) inadequate Federal Aviation Administration (FAA) procedures for transfer of communications among ATC facilities near the Hudson River Class B exclusion area; and (3) FAA regulations that did not provide adequate vertical separation for aircraft operating in the Hudson River Class B exclusion area.
