Loss of separation
By press agency :
An aircraft separation incident over the Atlantic Ocean involving two passenger aircraft is being investigated by the U.S. National Transportation Safety Board (NTSB). The two aircraft involved in the incident were a Boeing 737-800 operated by Delta Air Lines, and a Boeing 747-400 operated by Russian carrier Transaero. No one was injured.
According to information provided by the NTSB, on August 28, 2008, at approximately 18:37 Atlantic Standard Time, the two aircraft "came within zero feet vertical and 1 minute lateral separation at an altitude of 33,000 feet about 179 miles north of San Juan, Puerto Rico." The incident occurred over the Atlantic Ocean in a non-radar environment where 15 minutes of lateral separation is required.
The NTSB says that the Transaero 747 "descended 200-300 feet after receiving an alert from its Traffic Collision Avoidance System (TCAS). " The NTSB statement did not mention what action was taken by the Delta aircraft.
The Transaero Boeing 747-400, operating as Flight TSO554, was en route from Moscow Domodedovo International Airport to Punta Cana International Airport in the Dominican Republic. The Delta Air Lines Boeing 737-800, operating as Flight DAL 485, was en route from John F. Kennedy International Airport in New york to Piarco International Airport in Trinidad.
