6/17/2014 - MISAWA AIR BASE, Japan -- (This
article is part of a series featuring the 35th Maintenance Group on
their ability to generate airpower for the 35th Fighter Wing's Wild
Weasels. The 35 MXG is compiled of 22 career fields that support the
mission of the Suppression of Enemy Air Defenses, the only SEAD wing in
Pacific Air Forces.)
When Airman 1st Class Ashton Youngblood was 17 years old, he spent an
entire year rebuilding a Ford F-150 pickup truck from the ground up. He
didn't know it at the time, but it was just a minor tune-up for what his
career had in store.
A couple years later, he traded his backyard garage in Missouri for one
in northern Japan that stores a little more horsepower. When he walks
into work these days, he's surrounded by huddles of hulking F-16
Fighting Falcon engines. Today, there are 10 engines in the hangar and a
combined 1 million horsepower between them.
They're the heart and soul of a fleet of 44 F-16s stationed at Misawa,
and it's up to Youngblood and his fellow aerospace propulsion
maintainers to bring them to life.
"These engines are what the jets are built around," Youngblood said.
"The work we do back here is what really sends them off the runway."
Aerospace Propulsion is commonly referred to as "props," and every day
around 80 props Airmen ripple into their hangar, ready to repair engines
and set the frame for mission-ready fighter jets. They'll use hundreds
of tools, utilizing things like bore scope cameras to see hard-to-reach
places inside the engine, dry ice to condense specific parts and basic
wrenches for bolt turning.
Youngblood works in the Jet Engine Intermediate Maintenance section in
the props back shop, where the vast majority of props Airmen work. It's
one of three major areas that fall under aerospace propulsion, and they
work hand-in-hand with flightline engine troops and engine test cell
maintainers.
Following each flying day at Misawa, flight line props run extensive
tests on each F-16 engine using computer programs to analyze and monitor
different parameters to ensure they're functioning properly, said Staff
Sgt. Jeremy Howard, 35 Aircraft Maintenance Squadron.
With Misawa pilots flying more than 6,000 sorties annually, the cohesion
of back shop and flight line maintainers must remain solid and fluent.
It's a story of two different worlds working together. While Howard and
about 10 other flight line props troops battle the elements and fast
pace, the back shop digs into depths of the engines seen by no other
maintainers.
"It's a higher tempo out here [on the flight line]. We have to
constantly push sorties so the pace is a little faster," said Tech. Sgt.
Keith Wright, 35 MXS. "We all work well together and everyone plays
their part."
Following testing and downloads on the flight line, Howard said they'll
review the information and either perform maintenance on the fly or turn
to their counterparts for more advanced and hard-to-reach help.
"Basically, anytime the flight line has more maintenance than quick
fixes on the engines or identifies upcoming long-term maintenance,
they'll send it to us at the back shop," said Airman 1st Class Hannah
Stout, 35 MXS, who has spent the past year fixing engines at Misawa.
Once at the back shop, the elaborate hands-on dissection begins.
"What we'll do is receive an engine, tear it down, inspect any parts, and replace them," Youngblood said pragmatically.
It's hardly that simple - unmasking a 5,530-pound engine is no easy task, but it's one props troops take on wholeheartedly.
"It's a big deal - the F-16 is a single-engine jet, so everything we do
must be exact," said Staff Sgt. Rubiani Navarrette, 35 MXS. "It's very
complex at first and a lot to take in, but after a while you get used to
it and take pride in going in there and doing your job with no
problems."
Back shop maintainers practically swarm an engine to break it down --
some on wheeled seats deconstructing the underside, some scaling the
engine's sides and top, and others reviewing technical orders and
supervising the process. They're patient and methodical, calling others
in for opinions and assistance to ensure perfection.
"The most challenging part is what you face mentally," Youngblood said.
"You're always learning something new and relying on coworkers to get
the job done."
Disassembling an engine usually takes around a week, and putting one
back together takes about double that. Along with faults and fixes,
scheduled maintenance as part of a service life extension program
requires that each engine be inspected thoroughly and necessary parts be
replaced after a certain amount of flying hours.
On top of supporting Misawa's Wild Weasel mission of the Suppression of
Enemy Air Defenses, the props back shop is a designated Central Repair
Facility, meaning it also takes on the bulk of engine responsibilities
for both Osan and Kunsan Air Bases in the Republic of Korea.
"We support the entire Pacific theatre," Youngblood said. "It means a
lot to know we're part of the bigger picture. We have a hand in every
jet that flies out here."
When all their hard work comes to a head, the final piece of the trio -
the engine test cell maintainers - bring the engine to life.
About once every week, an F-16 engine is loaded into the test cell's
"Hush House," a warehouse-like structure designed to muffle the roaring
sound of jet engines. It's the final test after hours, days and months
of laboring work.
"It's our goal to catch any last issues and have each engine ready to go
before it reaches the flight line," said Staff Sgt. Joseph Martinez, 35
MXS. "It's imperative to have our end squared away so maintainers
aren't spending any more time troubleshooting and making repairs."
A 15-foot flame on full afterburner and an engine thrust up to 30,000
pounds signifies a job well done and another engine ready to support the
mission of Misawa.
"That one pilot is putting his or her life on the line to keep the rest
of us alive," said Staff Sgt. Mitchell Morelos, a 35 MXS test cell
maintainer. "It means everything to us to know that props is the reason
those jets are in the air."
It's a demanding job, complete with incomparable satisfaction. While
some just see it as another day at work, Youngblood said his life around
engines takes on another meaning.
"I see these engines go into jets and watch them take off," Youngblood
said. "We take a lot of pride in knowing we played a part in protecting
our people on the ground."
