At our FW the Jet Engine Technicians do all the engine and starter maintenance. I believe most the Active Duty has the Crew Chiefs do the engines/starters on the line. The ANG is mixed from what I can tell...

Here's the question; Who does the Engine and/or JFS maintenance at your installation? (Engine Shop, Crew Chief, etc...)

I'd like to hear from some FMS operators as well, I'm intrested to know their take on engine/JFS operations.

Not that this isn't an international forum, but I would like to know where the answers are from.

Spangdahlem GE, Crew Chiefs do the engine maintenance and starter maintenance. However engines is out there to assis with the engine removal and instalation but not the interim inspections. However any engine maintenance due on the engine it's self the engine shop does most of it, with augmented help from the crew chiefs. In my experience if the engine guys are assigned to the specialist section it is the engine shop doing the engine work. However if the engine guys are assigned to the crew chief flight then the crew chiefs get all the engine work, even if there are no engine guys available.

Aviano Italy here... IDCrewDawg sums it up for us here as well. We have Engine guys who do most troubleshooting but we have crewdogs who can troubleshot as well. Crewdogs do all the starter maintenance...

I have been at Spangdahlem, Osan, Edwards and Nellis and it is the crew chiefs doing 90% of the work. The manual labor mostly: pulling panels, pulling engines and changing the LRU's. The Engine troops will come out to do their engine
"troubleshooting" and then disappear "leaving it for swings" which means the crew chief jumps in to fix the problem. As far as start system problems it is a crew chief system, but I have known 1 or 2 great engine troops that treat it as their system and handle it. When I was at Edwards there was little crew chiefs could do to the engine since there were civilians in the engine backshop. They could file a greivance with their union if GI's take work away from them i.e. trouble shooting or replacing LRU's on the engine. The only thing crew chiefs could really do was pull the engine.

There are only certain components and tasks that can be accomplished on the engine by flight line personnel, anything other than those tasks must be performed by the engine backshop.

On a side note I have friends over in the F/A-22 CRaptor community and they tell me that they will not need or have engine troops on the flightline. Apparently they will have a system similar to and/or better than the DESSC/TDEU that when downloaded will tell the crew chief what is wrong.

O.T.

Read some articles about the 22 and other recent aircraft comming out with a system reporting capability, even heard that the jet trasmits that data back to the maintenance so they know what tools and equipment to bring out to the jet before even comming out to analize the problem. On another note, heard the 22 has NO saftey wire, all I can say is I sure hope so.

Hey ID, not only does it report back to maintenance, but to supply which will run an inquiry and order the part. Can you believe that?

Also it's true about the safety wire.

Ahh.......the fine art of safety wire.

Yes even our F100-PW-220s and -229s are now finished with safety-cable.

It too has it's short-falls, but is alot easier to install most of the time.

Only place you're not authorized to use the safety-cable on the -229 is primary-gas path, and oil-wetted compartments.

Hi guys,

In Holland it's a mixture of people.

The engine guy does NOT help with the removal of the engine and JFS.

Pulling the pannels is done by crewchiefs and asst. crewchiefs.

The engine will be removed by crewchiefs/asst. crewchiefs and hangar personnel mostly a group of 4 people who take out a engine.

The JFS is mostly removed by a hangar personnel.

The engine people only do the inspections on the engines when they are out of the jet and read out the engine and do the JOAP samples and do the engine runs and solve little problems with the JFS if it has a start 2 fail.

Engine guys have the easy job in my eyes but I rather be busy.

Colorado ANG-Crew chiefs do all starter maintenance. They assist engine shop on the removals.

All JFS maintenance is done by our a/r shop. We do not have starter maintenance on our 623's as it is a function that is taught at crewchief school. Hell, we do not even pull engines at home station only TDY.

NM ANG, Engine shop pulls and stuffs motors. Crewchiefs remove, work on, and stab JFS. I had to instal and remove and re-instal a JFS on one of our airplanes about 20 times. Bleed and leak checks and bad conical seals and a leak that I couldn't find. Not bad for my first JFS work. LOL (It sucked don't give me grief)

If you did a JFS change in 20 minutes, it's no wonder it leaked.

Important items for a JFS change:

1. Time
2. All new seals
3. Pet
4. Bees Wax
5. 1 additional person w/2 hands
6. More Time

Those tubes/connections are very damage prone; very easy to kink/cross-thread. By our Engine Shop doing most JFS maintenance, we build a very high proficency at our unit. There are a few CCs who help out with thier JFSs. They seem to want to learn the system so that it works, and not just, "slap a new one in there so I can launch the jet....."

Not something you want to hear when you only have one engine under your @$$.

The first time you see a Viper's JFS on fire you'll thik twice about a "JFS quick change"

Bix,
He said he did it 20 times..........not in 20 minutes.... Cool

Have a great day!

Yes, sorry Opie

Still proves a point chickenlegs............

Take your time and do it right the first time! And/Or Don't always perform "Shotgun Maintenance" and assume the JFS is the fault; experience matters!
