GAO examined 46 types of aircraft and found that only three met their annual mission capable goals in a majority of the years for fiscal years 2011 through 2019 and 24 did not meet their annual mission capable goals in any fiscal year as shown below. The mission capable rate—the percentage of total time when the aircraft can fly and perform at least one mission—is used to assess the health and readiness of an aircraft fleet.
[Emphasis added by me]

Continuing.
quote:
For fiscal year 2019, GAO found only three of the 46 types of aircraft examined met the service-established mission capable goal. Furthermore, for fiscal year 2019:
• six aircraft were 5 percentage points or fewer below the goal;
• 18 were from 15 to 6 percentage points below the goal; and
• 19 were more than 15 percentage points below the goal, including 11 that were 25 or more percentage
points below the goal.
Program officials provided various reasons for the overall decline in mission capable rates, including aging aircraft, maintenance challenges, and supply support issues as shown below.

... GAO was asked to report on the condition and costs of sustaining DOD’s aircraft. GAO collected and analyzed data on mission capable rates and O&S costs from the Departments of the Army, Navy, and Air Force for fiscal years 2011 through 2019. GAO reviewed documentation and interviewed program office officials to identify reasons for the trends in mission capability rates and O&S costs as well as any challenges in sustaining the aircraft. This is a public version of a sensitive report issued in August 2020.. Information on mission capable and aircraft availability rates were deemed to be sensitive and has been omitted from this report.


Interesting that the ONLY aircraft meeting its mission capability goal every year of the study is the USAF’s UH-1 helicopters. They’re quite familiar to me here because F.E. Warren AFB uses them in its missile defense system mission. This seems to be their most common role, support of missile defense across the country, although some Air Force Hueys are based near Washington DC to fly government officials away from the capital should the need arise. I believe I read were talking about just 34 helos.

The numbers are eye opening and it’s incredible to me that half the military’s aircraft did not meet their mission capable goal in ANY year of the study. You’ll see that we have a problem with parts availability in particular, and for most of our country’s aircraft.

It’s a 248 page report, but you can glean a lot of information with just 15 minutes of study.

1st, I have not read the report.

2nd, you have to understand the terms FMC (fully mission capable) and PMC (partially mission capable). I am guessing that most of the aircraft I flew during my career were PMC (including my time deployed in a combat zone). They were fine for the mission I was flying that day/week, just not ok for every mission they could possibly be tasked for.

Would I have rather been flying aircraft built in 2005 vs 1974? Sure. Is is as bad as it sounds? Nope.

What is the NMC rate?

NMC - Non Mission Capable (can't fly)

PMC - Partial Mission Capable (able to fly safely but cannot perform some of its mission (like can't shoot guns but can shoot missiles) )

FMC - Full Mission Capable (can do everything the aircraft was designed to perform)

Now with that, during Desert Storm VF-1 and VF-2 (USS Ranger, CAG-2) had one NMC aircraft between them (24 aircraft total). All i can say is trust me, in war time, standards change when air medals (with a "V") are considered. Wink

To me anyway, 46 types seems like a lot. Now I will spend all weekend trying to name them.

In my experience with Army, DOD and GAO auditors, many of them didn't have a clue as to what they were auditing.

I may have misread, but I thought I read that each military service told the GAO what they defined as “mission capable” and therefore what to audit.

I can only speak on how the Navy does it's reporting.

Each Squadron reports up to their Type Wing (AMSRR), and then each Wing reports their rates up to Naval Air Forces. The reports state how many aircraft each squadron has "In Reporting" (a aircraft can be out of reporting if its going though rework or Mod, ect...) The report also states the number of aircraft that are FMC, PMCM, PMCS, NMCM, NMCS. An Audit would be easy to do for the GAO

Back in my day we would try to consolidate all the PMCS or NMCS grips against one bird so our FMC rate would be as high as possible. I understand now they have more of a truth in reporting system.

No need, they're all in the chart on page 2. And it depends on your definition of the word "type." Under cargo the C-130 is listed three times as a T, H, and J. Then twice more under refueling as a T and a J. The AC is not listed.

The AC-130 is not a type, but a mission. The AC-130 uses three types; the AC-130J, AC-130U, and AC-130W.

The AC-130W is an C-130H model with some package additions, but an H model none the less.

The AC-130J is a C-130J model.

The AC-130U is a also a modified C-130H model.

I would like to see the data breakdown and how/what data was requested. When the data was collected would be nice too such as pre/post deployment. I'd like to see the tasking, FMC/PMC/NMC rate, mission completion rate, and failed sortie rate graphed.

At the end of the day the real questions are:

1. Are the requested missions being completed regardless of FMC/PMC/NMC rates?
2. In relation to mission completion rates, is there excess capacity to overcome
aircraft that go NMC during preflight/launch?
3. Is there excess capacity to meet unforeseen/war/power projection missions?
4. Are less taskings being doled out due to a higher NMC rate?

Probably more and better questions.

Those are very good questions. As TMats implied, any answer with specific numbers will be classified.

These type of reports you gotta read between the lines. As others have mentioned, the bird may not be in perfect working order (cranky left gear, 1:3 radios not working right, can't connect to SATCOM, one of the modes not working on the display, etc..) BUT, if it can fly safely and perform 80% of it's mission-set, that may be good enough.

AC-130U is retired. We only have J and a few W remaining. Within 2 years the fleet will be pure ACJ.

In the Navy NATOPS and The Mission Essential Subsystem Matrix (MESM) determines what systems are needed to perform a mission. If you have a gripe against one of the system components the aircraft must be listed PMC.

True: still H models and J models, though.

Disclaimer: I flew A models (and no, they didn't have wooden propellers).
