I don't believe there is an updated Parts Usage Flowchart. After taking a quick look at the 2009 flowchart, with the exception of the "Traction Devices" box I believe that the flowchart should look about the same for this year. You may be able to use the 2009 Flowchart as a starting point to quickly determine whether a part may be legal or not.

Based on the lack of a Parts Usage Flowchart for this year you will either have to be very familiar with or review the Section 8 rules for an individual part you are questioning the legality of.

The 2010 Rules, Updates and Q&A are, as always, the only official source of rulings for this year's game so any use of last year's flowchart in the manner I mentioned above is unofficial, non-binding and should on;y be used as a starting point if at all.
