ISO dock keeps Yokota, Kadena flying high

9/8/2011 - YOKOTA AIR BASE, Japan -- Every C-130 Hercules from Yokota and Kadena Air Base must undergo a unique and extensive two-week inspection every 540 days, and when they do, the 374th Maintenance Squadron isochronal inspection team, know as ISO dock, comes in to do job.

When the ISO dock performs an isochronal inspection, they strip most of the content off the aircraft's frame and body to inspect it 100 percent.

"The purpose of the ISO dock is to find naturally occurring defects before they become problems," said Staff Sgt. Anthony Miller, 374th MXS crew chief.

Problems for the C-130s can range anywhere from corrosion and cracks to tension and hardware checks.

"What we do during inspections is find the problems and fix them," said Senior Airman Travis Farr, 374th MXS aerospace maintenance technician. "It keeps these planes mission-ready."

During the inspection, the planes are divided into five different sections. Each shop in the ISO dock performs its own specialty inspections on all the different parts of the aircraft. Splitting the plane up ensures that nothing is missed and that personnel inspect the entire aircraft.

"We're taking a closer look than flight line personnel do during their pre-flight and post-flight inspections," said Sergeant Miller.

Since Yokota has the only C-130 ISO dock in the Pacific region, C-130s from Kadena are brought here to be inspected.

Yokota and Kadena together support more than 20 C-130s. As such, the Airmen in the ISO dock play a key role in keeping the Pacific Air Forces' mission going.

For Senior Airman Allan Cafeey, 374th MXS aerospace propulsion journeyman, seeing the newly inspected planes tear through the clouds is what being in maintenance is all about.

"The best part of the job is when we basically rebuild the entire engine and it goes out to fly," said Airman Cafeey. "It's a really good feeling to see that happen."

Once all of the inspections are preformed, the ISO dock Airmen reassemble the planes, check their operability, then send them back mission-ready to their respective places.

"There's great satisfaction in seeing the work that we do go up in the air every day," said Sergeant Miller.
