The National Transportation Safety Board today found a problem with a piece of equipment on the rudder of the small aircraft that crashed and killed two people in Taunton, and its presence will now be a part of their investigation, officials said.

Also killed was the man flying as co-pilot, Roland Deslauriers, 61, of Bridgewater. Full story for BostonGlobe.com subscribers.
