US investigates Army helicopter altitude in fatal January crash

The National Transportation Safety Board announced on Wednesday that tests revealed faulty altitude data on U.S. Army chopper aircraft like the one which collided with a plane of American Airlines on January 29 near Ronald Reagan Washington National Airport, killing 67 people.

The NTSB's investigation will examine the air data systems, altimeters and the Federal Aviation Administration's oversight over Washington airspace as well as air traffic.

The accident, which occurred a half mile southeast of the Potomac River airport and over the Potomac River, was the worst U.S. aviation disaster in 20 years. Army helicopters were found to have a discrepancy of up to 130 feet between their actual altitude and the height they reported in flight.

The NTSB played audio clips of communications between air traffic towers in the minutes leading up to the crash, including a controller's request to the American Airlines aircraft to move to a new runway.

The NTSB had previously stated that the helicopter was flying higher than the altitude recommended for the area when it crashed.

The collision happened at a height of approximately 300 feet, which is higher than the maximum altitude the helicopter could have reached.

A crew of experienced Black Hawk pilots was wearing night vision goggles while on an evening training flight.

After a close call on May 1, which forced two civilian aircraft to abort their landings, the FAA banned the Army in May from helicopter flights near the Pentagon. This week, the FAA said that the helicopter flights were still on hold despite the fact that the agency had announced it had signed a revised agreement with the Army in July.
