A brave new world for Army maintenance...


Hold the phones and stop the presses... the Army Research Laboratory has developed NEW aircraft maintenance technologies for the FAA.  

Before we send out the thank you notes, what exactly are these cutting edge and heavily researched technologies that our taxpayer-funded researchers hath wrought?  
The first one is the Health and Usage Monitoring System, or HUMS for short.  This quite valuable and capable system collects data from various sensors on helicopters which aims to predict impending failures of critical components.  It was developed by... wait for it... helicopter operators in the offshore oil industry.  And we have had it fielded in our civilian helicopter fleet for many years.

The second and even more technically advanced system that is sure to rock the civil rotorcraft industry is called "Condition Based Maintenance" or CBM.  For the less technically inclined, CBM means "replacing parts when they need to be replaced" which will eventually supercede the former Army system of "time-scheduled maintenance" or "replacing parts regardless of whether they need to be replaced".  

In practice, CBM states that you will regularly inspect certain components and replace them when necessary, while time scheduled maintenance means your maintainers spend countless man hours removing components at set times regardless of the condition.  Quite like changing your engine every 3,000 miles instead of changing the oil.  This is known in some quarters as "wasteful", "pointless" "stupid" and "a grievous waste of time and money".  

This is why civilian operators, with limited budgets and clients with limited patience, have been doing condition based maintenance for years, with strict governmental oversight.  

Some in the military will argue that time scheduled maintenance has historically been necessary because of the size of Army aircraft, the stress on components, the pace of operations, blah blah and so forth.  This argument works best on those who believe that the Army is the sole repository of aviation knowledge on the planet and think that an aircraft with 10,000 hours belongs on a pole in front of a museum.  

I would argue that the Army pays thousands of people millions of dollars to keep hundreds of aircraft broke most of the time, and that they are idiots with unlimited funding who think they know everything.  Regardless of how you might feel about this, I would bet you a paycheck that most civilian companies would be out of business by lunchtime if they managed maintenance like the Army.

I will further argue that the most outside-the-box thinkers in the Army probably brought these long standing civilian processes and systems under the Army umbrella, relabeled them with a cool sounding acronym, and then got themselves a nice OER bullet out of it.  

Glad to see the greatest minds in the Army are slowly catching up, and I can't wait to see what they come up with next.

Let me be clear...


Disarm the Afghans


There is a really easy way to cut down on the number of green on blue shootings in Afghanistan, Disarm the Afghans in any situation where they could be a threat to NATO troops.  

Far from being a ridiculous suggestion, this is a common practice for the US military, who disarms their own people in Afghanistan when the SECDEF visits, and who restricts firearms on stateside installations, leading to events like the murders of 13 troops on Fort Hood.  

The military has long since passed the point where political correctness is prized above force protection.  If we are not willing to take drastic measures to protect our own people from our alleged allies, its time for us to leave Afghanistan.  And its time.  

An unemployment numbers allegory...


Let's say when I'm 19, I say to my Dad: "If you pay my room and board and tuition for the next four years, I promise I'll never fail a class".  

Then I proceed to flunk every class for the next three and a half years.  All along the way I blame the school, my professors, society, my enemies, everything but my own performance.  

Finally, in the second semester of what is my fourth freshman year... I pull out a D minus in ONE class.  

So then I say to my Dad: "My grades are at a 44 month high!  See, I just needed a little time to see the results of my study habits.  How about paying my way for another four years?"

Would my Dad be a racist if he didn't believe me?
