Aircraft Maintainer Saves Air Force $5 Million

Air Force Tech. Sgt. Dennis Hertlein is an avionics, electro-environmental and propulsions systems expert. But he`s not your average specialist flight expediter -- his expertise has saved the Air Force $5 million.
Hertlein, assigned to the 57th Aircraft Maintenance Squadron, worked with teams to complete modifications and upgrades to Nellis Air Force Base`s F-16 fleet locally, rather than having to send them to a depot. The idea decreases costs and increases aircraft availability.
Specifically, he helped upgrade five F-16s with an advanced electronic countermeasure system. Hertlein also aided in developing the Tulsa [Oklahoma] Air National Guard [Base`s] identification friend-or-foe system upgrades and helped identify an engineering error during electronic warfare management system modifications on 22 Ohio Air National Guard F-16s.
I went TDY out to Toledo, Ohio, to see how the Ohio Air National Guard performed their upgrades and use the lessons learned for out upgrades here, " Hertlein explained. The Tulsa ANG came here TDY to assist us with our upgrades. We worked with their personnel to ensure that our modifications went smoothly. "
Attention to Detail
After the upgrade, there are still three separate systems -- threat warning, jamming and electronic countermeasures -- but now have one centralized control. Hertlein said threat detection was increased by 80 percent, due to the easier user interface of the centralized control.
We worked hand-in-hand with engineers from Hill Air Force Base [Utah] while modifying the jets, " Hertlein said. While going over wiring schematics, we noticed that two wires were going to interfere with an upcoming upgrade, and it needed to get sorted out. "
Hertlein`s attention to detail prevented future system failures stemming from the interference caused by the wires.
Hertlein insists he was just doing his job.
The upgrades come in a packet that tells us what to do, " he said. The engineers will do it on one jet, [and] then they give us instructions on how to do it. A lot of it is just learned over time through experience and working with it constantly. "
Hertlein`s former supervisor, Air Force Master Sgt. Maximilliano Heredia, said he was impressed by Hertlein`s meticulous work ethic.
He didn`t need too much encouragement, " Heredia said of Hertlein. You have to know your people`s strengths and weaknesses. I knew he would be perfect for the job. The entire documentation of the modification was error-free, from aircraft forms to the maintenance databases.
He`s a hard-driven NCO who drives his airmen as hard as he drives himself to get the mission done, " Heredia continued. His attention to detail and technical expertise is what sets him apart from his peers. "
Heredia also said he encourages airmen with potentially great ideas to not be afraid to come forward with them and to chase their ideas down, just as Hertlein has done.
