NTSB: ASA CRJ900 'sustained substantial damage' in Boston incursion

US National Transportation Safety Board, which has opened an investigation into last Thursday's Boston Logan runway incursion, provided more details on the incident (ATW Daily News, July 15).

NTSB said the Delta Air Lines Boeing 767-300ER was moving on BOS taxiway B, headed for departure on runway 04, when the winglet on its left wing "struck the horizontal stabilizer" of the Atlantic Southeast Airlines Bombardier CRJ900. The regional jet was sitting idle, third in line on taxiway M waiting for departure on runway 09.

"The CRJ900 sustained substantial damage, which included damage to the horizontal tail and vertical tail," NTSB stated, adding that "the airplane lost fluid in all three hydraulic systems. Parts of the 767 winglet were sheared off and embedded in the tail of the CRJ900. The passengers on the CRJ900 were deplaned on the taxiway and the 767 taxied back to the terminal."

The board said flight data recorders from both aircraft will be transported to its headquarters in Washington. DL, ASA, FAA and the Air Line Pilots Assn. will be parties to the investigation.
