FIRE FLAP ASSEMBLIES
The LT is outfitted with a main engine combustion air fire flap assembly (figure 2, item 1). This arrangement upgrades the
previous blanking plate arrangement that was used to secure the main engine intake if a catastrophic casualty required
shutdown of a main engine. The main engine combustion air fire flap assemblies are rectangular in shape, and their quick
release T handles (figures 3 and 4, item 1) are located at the front of the stacks on the 02 level. Access to the main engine
combustion air fire flap assembly is gained by entering the manhole cover on the stacks at the 01 level.
