## Discrepancy

C/W SB TFE 731-72-3471, A REWORKED SUPPORT AND SEAL ASSEMBLY MUST BE INSTALLED.  THIS REWORKED SUPPORT INCORPORATES A HONEYCOMB SEAL AND IS IDENTIFIED AS P/N 3072412-3.  BIZJET ORDERED AND RECEIVED FROM ALLIED SIGNAL (THE ENGINE MANUFACTURER), A SUPPORT AND FAA FORM 8130-3, BOTH IDENTIFIED AS P/N 3072412-3.  HOWEVER, THE PART IS ACTUALLY A 3072412-1.  THE DASH 1 SUPPORT INCORPORATES AN ABRADABLE SEAL.
