Abstract
A gas turbine engine assembly includes an inlet lip assembly, a fan containment case, and a front flange. The fan containment case surrounds a fan section and is positioned downstream from the inlet lip assembly. The front flange is mounted between the inlet lip assembly and the fan containment case and is positioned upstream from the fan section.

A nacelle assembly, comprising:
- an inlet lip assembly;
- a fan containment case surrounding a fan section and positioned downstream from said inlet lip assembly;
- a front flange mounted between said inlet lip assembly and said fan containment case, wherein said front flange is positioned upstream from a nose cone of said fan section;
- and
- said fan containment case attached to a downstream side of said front flange.
