The National Transportation Safety Board (NTSB) says it is investigating a collision in Boston between two airline jets that occurred on July 14, 2011, at about 7:33 P.M. EDT. According to the safety board, a Delta Air Lines B767-300ER (N185DN) operating as Delta flight 266, was taxiing on taxiway B for departure on runway 04 at Boston Logan International Airport (BOS), when its left winglet struck the horizontal stabilizer of an Atlantic Southeast Airlines CRJ900, N132EV, operating as ASA flight 4904.
The ASA CRJ900 was number three in line on taxiway M waiting for departure on runway 09, says the NTSB.
A brief narrative provided by the agency said that as the B767 approached and passed the intersection with taxiway M, the left winglet of the B767 struck the horizontal tail of the CRJ900.
The CRJ900 sustained substantial damage, which included damage to the horizontal tail and vertical tail. The ASA CRJ900 regional jet also lost fluid in all three hydraulic systems. Pieces of the B767 winglet were sheared off and found embedded in the tail of the CRJ900. The passengers on the CRJ900 were deplaned on the taxiway, and the B767 taxied back to the terminal, according to the NTSB.
