S-92 Filter Bowl Assembly
NL, I just cannot recall how the decisioning went as to the filter install location on the S-92. I can guess that one factor was ease of access. On the Hawk, all one does to get at the filter is remove the troop seats and very simple cargo compartment roofing. And by the way, when the filter is pulled, some rags and a container are necessary, as there is the possibility( probability in my experience ) of a bit of oil spillage. In the S-92 the interior roofing is much different. More complicated, bigger parts, not inexpensive and items that you don't want to get oil-stained. Just a guess on my part.
