COLORADO SPRINGS, Colo. (Reuters) - Gencorp Inc on Tuesday pushed back against comments by Orbital ATK Inc that blamed the Oct. 28 Antares rocket explosion on excessive wear in the bearings of its AJ-26 engine, and said its own probe found the root cause to be debris in the engine.
GenCorp spokesman Glenn Mahone said his company's independent investigation would be completed in about three weeks, but the bulk of the work had been done. He said Orbital's statement was "inaccurate and could be misleading."
He said GenCorp's investigation identified excessive wear of the bearings as the direct cause of the explosion that destroyed a rocket bound for the International Space Station, but further research revealed that the bearings likely wore out due to "foreign object debris" in the engine.
