Tanker 116 in Boise

We shot this photo of U.S. Forest Service air tanker 116, an HC-130H, in Boise on April 20. It was there to deliver the MAFFS unit it has been using so that the Reno National Guard folks can train with it and the other one normally assigned to Reno. After the training the unit will be retrieved by T-116 and hauled back to McClellan in California where that tanker is based.

Two C-130’s and their crews from each of four military bases — Channel Islands, Cheyenne, Colorado Springs, and Reno — are going through their annual training and recertification in Boise this week.

Jon Wright took this photo of Air Tanker 116, which is one of the first of the seven HC-130H aircraft the U.S. Forest Service acquired from the U.S. Coast Guard to be converted to an air tanker.

Mr. Wright said it spent several hours on February 27 and 28 conducting approaches at Mather Airport east of Sacramento.

One of the last steps in the conversion of a U.S. Coast Guard HC-130H into an air tanker for the U.S. Forest Service is applying 80 gallons of paint. The aircraft that just received the new livery is the first of seven that will be going through the transformation over the next several years.

Much of the work is being done at Robins Air Force Base in Georgia. This was a unique project for the Air Force. Normally the paint the workers use is designed to minimize the visibility of their aircraft, but the goal for an air tanker is just the opposite. They had to do shiney gloss red and white, instead of flat grey.

The article below does not specify, but it is likely that the aircraft being worked on is Tanker 116, formerly Coast Guard #1708, which is scheduled to be delivered to McClellan Air Field this month. It will operate with a slip-in MAFFS 3,000-gallon retardant system until a permanent retardant delivery system can be installed.

ROBINS AIR FORCE BASE, Georgia

Painting a C-130H with a new glossy paint scheme doesn’t happen very often in the Corrosion Control Flight at the Warner Robins Air Logistics Complex.

Most of the time its professional cadre of aircraft painters spray on the customary flat gray color familiar on many a surface of weapon systems that visit Robins from across the globe.

But earlier this month things turned a bit more colorful inside one hangar on the flight line, thanks to a visit from one particular aircraft making its way through the final stages of programmed depot maintenance here.

During its visit here, the Coast Guard aircraft received a new center wing box, replacement of its outer wings and work on its elevator, all before its upcoming transfer to the U.S. Forest Service where it will eventually assist in firefighting missions.

The new USFS paint scheme – the first to be laid out on an aircraft – involved hours of tedious work from a team of nearly 45 painters. Much of it involved the careful laying of tape across parts of the plane. That’s so that once a different color of paint was applied to an area masked over, a precise fine line could be seen once the tape was removed.

What you want is a nice, sharp edge on those areas where colored paint is applied. Putting down that tape didn’t involve a laser level of any kind – it was all done freestyle by hand.

“It was a real challenge,” said Ronnie Harrell, Corrosion Control supervisor.

One of the first things you’ll notice is an eye-popping ‘poppy red’ shade that spans from the nose to the tail, and under both wings, along with a thin layer of black that carefully curves along the edges of the former’s dominant color scheme.

There are some nine different colors represented on the aircraft, ranging from yellow and light gray, to matte black and white.

It took about 80 gallons of paint to cover every inch. But it couldn’t all be done in one sitting. Once areas were masked, touch-ups were made, sanding happened and things were rinsed. Thousands of surface points were then seam-sealed, similar to a caulking process, which in this case keeps water from penetrating into the aircraft and causing corrosion.

Once that’s done, PreKote is added across the aircraft, which acts as an adhesion promoter so paint sticks. Once this dries, then the masking process starts. All this before a coat of paint even touched anything.

A coat of white was first applied over the entire aircraft. Then you wait for it to dry. Then it’s applied two more times. Because so many different colors were involved, there was a lot of waiting, sometimes as much as a 12-hour dry time in between paint applications.

Workers had it down to a routine by the end, alternating between demasking areas of the plane, masking, painting, drying, then waiting. Then they repeat the process once other colors are added.

In getting ready to first apply a coat of poppy red over a large swath of the aircraft, you had to make sure the paint underneath was dry. Then mask the surrounding area so any overspray wouldn’t get anywhere.

“You want to give the paint plenty of time to dry between the two so it won’t peel off,” said Harrell.

On this C-130, which stayed in the hangar a little over two weeks earlier this month, a gloss paint was used, making things a little more interesting.

“You have a fine line between getting a good shine and a run,” said Harrell, referring to the careful technique of applying coats of gloss. “You have to worry about running with a gloss, but not as much as with flat. It will run, but not as much.”

He added, “It’s hard to get a big area like this painted, and a challenge not to have paint colors bleeding into the others.”

Some of those challenging areas were laying out the tape prior to applying poppy red, adding stripes, and adding tape under the belly of the plane. Curves toward the tail also required some fine tuning as that involved quite an intricate layout.

A gray paint was also used for a walkway up on top. It’s a gritlike, sandy substance that prevents anyone who’s walking up there from sliding off due to the gloss.

In applying gloss, what you’re looking for is a nice sheen, not a heavy buildup, according to several aircraft painters. In applying the first coat of white, you put on an even coat, and by the final pass you’re trying to get it to shine.

A good estimate is to apply a coat at a distance of 14 to 16 inches away from the surface. It also depends on how fast you paint, since the closer you are to the aircraft, the faster you’ll paint in your spray pattern. Do it for awhile and you get a feel for how things should look, or in this case, shine.

“It looks a lot better than I thought it would due to the paint system we used,” said Paul Lowery, work lead. “It’s good to put out something different.”

Mark Stoddard, a quality assurance representative at Robins from the Coast Guard’s Aviation Logistics Center in Elizabeth City, N.C., has been following the aircraft closely for many months. Until the plane is installed at a later time with a Modular Airborne Fire Fighting System (fire retardant system), the Coast Guard will still maintain configuration management of the airframe and its maintenance procedures.

“Things have gone very well on this first aircraft,” he said.

Added Harrell, “We were really looking forward to this job. Once stencils were added and things started to take shape, it really started to look like what we do. The first thing people will see is that paint job.”

Photos of USFS Air Tanker 116

Earlier this week we posted a photo that showed a portion of Air Tanker 116. This is one of the seven HC-130H aircraft that are being transferred from the U.S. Coast Guard to the U.S. Forest Service to be converted to air tankers. Now we have four more photos that were taken by Bill Tinney while the aircraft was at Robins Air Logistics Compound in Warner Robins,Georgia. Thanks Bill.

The expectation is that T-116 will be delivered to McClellan Air Field by September 15. Sometime after that it will be operated as an air tanker using one of the eight slip-in MAFFS retardant systems until a permanent retardant delivery system is installed.

The photo above shows external fuel tanks hanging from the wings. I would be very surprised if the USFS operated the aircraft as an air tanker with the tanks. The HC-130H is designed as a long range search and rescue platform with a 5,000 mile range, longer than the typical C-130. In an air tanker role, fuel is not usually an issue, since it has to continually land to reload with retardant.

The HC-130H that is being transferred from the Coast Guard to the U.S. Forest Service that will be designated as Air Tanker 116 has recently received a new paint job. The projected delivery date to McClellan Air Field in California is September 15. Sometime after that it should be in service as an air tanker, but will be using on a temporary basis one of the eight USFS slip-in MAFFS retardant systems until a permanent retardant delivery system can be installed.

The paint design is similar what was approved over two years ago and the one on the recently acquired Sherpa C-23B aircraft, but varies a bit from the design, in that the engine cowlings are not red on the top as they are in the design and on the Sherpas.

HC-130H paint design
This is the US Forest Service approved paint design approved in January, 2014 that was to be used on the seven HC-130H air tankers acquired from the Coast Guard.

The USFS has a wide assortment of paint schemes on their firefighting aircraft fleet. This may have something to do with the power the regional aviation officers have over the programs in their regions, as opposed centralizing power in a national aviation program. We collected photos of some of the aircraft in January of 2014.

On August 11 we published a comprehensive update on the status of the transfer of the seven HC-130H Coast Guard aircraft.
