Brief Description: Work on the Cooling Duct and Cowl Interface
Placed the Cooling Duct and Cowl Duct Interface on the Cowl Bottom, and installed on the fuselage. Trimmed the aft part of the cooling duct some more and the outboard flange of the duct interface. Had to do fitting, marking and sanding several times before getting the 1/4 inch clearance between the interface the FF-1209 Seal Face. Drilled #40 holes in the interface and into the cooling duct.
