Walkaround #609

Sikorsky HH-60G Pavehawk

I'm including 46 photos of two aircraft. Even though there's two aircraft I've stuck to the walkaround concept as if there was one aircraft. One HH-60G is an old style configuration which is still out in the fleet, and the second HH-60G is the new configuration. I've indicated "old style" or "new Mod" in the photos so the readers can see the differences. Mainly that's with the placement of the RHAW gear or plume detectors, and positioning of the position lights. The old style had them on the main gear sponsons but the new Mod has them up on the ESSS fairings. This is due to the new Mod having plume detectors on the main gear sponsons.

OK, These pictures were taken at my unit's hangar. They are two Alaska Air National Guard 210th RQS (Rescue Squadron) HH-60G Pavehawks. One HH-60G (26472) is an old style configuration undergoing maintenance, and the second HH-60G (26466) is a new Mod bird. The photos were taken in December 2003.
