Thanks Mike,

Wing attach angles and the hat channels in the fuel bays are two huge areas of corrosion concern as I’m sure you are aware. I have shots of this destruction in my thread. A little education might save a lot of heartache down the road. Thanks for the info and photos when you can.

Dan

RyanShort1 posted a couple of pictures for me on another thread. These show the external rib problems, located behind a skin between the flaps and wing.

Just got this from our Maintenance Officer, Ray Clausen, in reply to my
query as to how Saturday went.

"Strange and not as well as we hoped. Didn't try to start her. Oil pressure
on both engines was low, based on the pre-oil instruction we got from the
engine builder. Thing is, it was the same. Everything seemed to be right
but the cockpit oil pressure gauge readings. We had 50 pounds at the pre-oil pump, but while turning over the engine, saw only 20 in the cockpit. The instructions said we should see between 35 and 60 pounds. Both engines showed 20 pounds (in the cockpit) when we went through the checklist.

Later, after we called it a day and were sitting around the table, we began
to think that the 35 to 60 pound range was supposed to be read at the
pre-oil pump gauge. If we make that assumption, then the 50 we were seeing was a very good value. Our pilots all seemed to think that 20 pounds while turning over, and just before it starts, is a good reading, but they weren't sure. Think about it, what is your oil pressure while turning over the engine but just before it fires?

The new engine sounds great turning over and there is no indication of any problem with it. We are just a little confused by the text of the
instructions and the readings we see, and I chose to wait a couple of days to speak with the engine builder rather than throw the dice and chance a start when we're not sure of the situation. Jim Liles and I will call them Monday morning for their opinion. If they agree, both Ron Dietes and Grant Lannon will be in and we'll crank her Monday.

We had another failure, too. Again, this is the best possible time for it,
though. The left wing feather pump made a whole lot of smoke after two of the planned three cycles. It was toast. We were saved when Ron Dietes mentioned that he'd had one overhauled and it was upstairs on a shelf. Took about an hour to swap good pump for bad and we charged on. If we'd had an in-flight engine failure and smoked the pump then, unable to feather the prop, it would have been a bad day indeed! The now-bad pump will be overhauled and shelved for the future.

We have the cable parts ordered and hope to see them Monday. We didn't have any of it on hand. The aileron trim pointer part will be fixed by Ray Ender and we should have it Monday. Could be back on track Wednesday for scheduling a maintenance flight.

On a side note about our sister B-25, Ron Dietes flew the Devil Dog back to Georgetown on Thursday. I understand that Beth is one VERY happy lady right now."

Ray Clausen
Maintenance Officer


Congrats to Beth for having her plane back home!

As you can see, we are taking our time with the Rose and checking and double checking, even triple checking things.

Just off the phone with the hangar. The Yellow Rose had engines running today! Just a few minor tweakings of carbs (one just off the bench) and some cables, etc., to do. Parts are on hand or enroute for the other minor repair items.

The light at the end of the tunnel is getting bigger and brighter!

I'll post a more detailed report from our maintenance officer tomorrow. I understand video was shot as well. I'm not sure where it will post, but I'll let you know when it does!

"We are Close to being back in the Air" was the headline of an Extra edition of the online Yellow Rose Squadron newsletter!

“The Yellow Rose roared back to life today” Stated — Ray Clausen

San Marcos, TX – Despite the heat, there were cheers, smiles, and thumbs-up everywhere. It has been a long time coming, and hearing all that gasoline turn into noise was wonderful! We were on the right track Saturday. The instructions we had for pre-oiling the engines were just a bit confusing and the numbers we were getting from the different
oil pressure gages caused just too much uncertainty to chance a start of the engines.

After the last foul-up during pre-oiling, I felt it best to stop and consult the engine builder before going on. I sure am tired of having to make those calls, but I'm sure it was the right call. This morning (Monday)
we phoned and got some guidance, and some reassurance, from Roy, the engine builder. After talking with him, we headed out to the plane with renewed optimism.

We essentially started from scratch and performed the pre-oiling process again. Just as we had on Saturday, each engine gave us the same oil pressure readings and those readings didn't match what the
instruction sheet said we should see. We charged on and when both engines were done, we retired to the break room for a brief rest and a call to Roy.

After a little phone tag, we got him on speaker phone
and Ron Dietes read to him the instructions we followed. Ron and I gave him every detail we could and asked his opinion on the engines and whether to start or not. I was insistent on a speaker phone so more
than one of us would hear Roy's response and instructions. There were lots of smiles when he said that it sounded like we had
thoroughly pre-oiled both engines and should start them and go through a normal warmup. He did say that if the oil pressure didn't come up within a few seconds that we should shut down the engines.

With that, we pushed the Rose out into the bright (and REALLY hot) sun and brought out the fire extinguisher. Ron and Grant climbed in while Jim Liles manned the fire bottle and the rest of us stood around looking like expectant fathers. When the right engine began to run, the cheers
almost drowned out the engine noise, but my heart was still in my throat and I couldn't breathe.

Maybe it was some sort of A&P connection between Ron and I, but he knew that noise wasn't the measure of success, oil pressure was, and I had no way of knowing how that was going. Ron looked around the plane and found me, and with a HUGE grin flashed me a thumbs up. Now I
was breathing again, but we had one more engine to go. As the new left engine rumbled to life, belching smoke, it took a few seconds to stabilize and heads were down and hands on the controls in the cockpit. Soon, the grin appeared again with the thumb pointed skyward, and my cheers
joined the chorus. It was a really great day!

We have some tuning to do and the prop governor cable adjustment is a pain, but its all downhill from here. Ray Ender brought in the repaired piece for our aileron trim control, so I'll be working on cables Wednesday. Once the cables are rigged, we can rivet up the flap area. When the parts come in for the gear release cable, we'll get it made and installed.
Unfortunately, we will have to do another retract test to check out the new cable but it does need to be tested.

I'll be coordinating with Mike Renck on scheduling the maintenance flight. As Operations Officer, he schedules pilots and I believe we are planning to have Al Maxwell fly her. It's best to have someone outside our unit evaluate her and he can turn around and start checking out our
pilots. Rest assured that we will get the word out when we set the date for the return to flight.

Many folks have worked incredibly hard to get us to this point. Some just can't make it out to the hangar and from many of them, I have emails of support and encouragement that have really helped during some of the tougher times. Some folks have begun to come out as we near
the light at the end of the tunnel. But I really want to express my heartfelt thanks to those have been with me through this entire
project, having no idea what the task of the day would be. Maybe sweep the floor, hang an engine, clean dirty parts, re-attach a wing. I've mentioned some individuals in previous newsletters but I won't get into that here. That list would be a long one! They know who they are. Their devotion to the project has been a blessing and an inspiration.

I'm honored to be the Maintenance Officer of the Yellow Rose
Squadron this period of the Rose's history and proud to work with all of the Squadron members.

Now, let's get her in the air!

Thanks!
Ray

I just wish I could attach the entire newsletter. I tried, but failed, to lift the photos of the start. Sure looked good!

Thanks Chris!!! That's just what this thread needed! Isn't that a beautiful sight? (and the front-on shot of the Rose in the background with engines running is nice as well!!!)

Plans are being made to go to Oshkosh! Of course we have to get the Rose in the air still, and get crews requalified, but it is looking like we will be there!
