                     b. If any bungee is incorrectly installed, remove the bungee and reinstall it correctly before the next flight.

                     c. Attach label, P/N FE289006200, to both left and right elevator overload bungees to show the correct orientation of the outboard end.

                     d. Re-identify the P/N to read "FE289000001" on the identification plate of both the left and right elevator overload bungees.

                   Previous accomplishment of Bombardier Service Bulletin 84-27-27, dated
                   24 May 2005, meets the actions detailed in Requirement 1a and 1b of this AD.

                   Previous accomplishment of Requirements 1a through 1d of this AD in accordance with the original issue (dated 8 February 2007), Revision A (dated

             This Amendment becomes effective on 28 August 2008.
Background:  Several production aircraft have been found with the elevator overload bungees installed in reverse orientation: i.e. larger end outboard rather than inboard.  This bungee reversal does not impact normal operation of the elevator and would not increase
