I'm a pats number guy. With that, I'm able to look at many possibilities. A picture might help as well.
No, never thought about it! It is just a plastic knob about 1.5 inches in diameter and it screws onto the side of the console. I think John Talmadge with Diamondaire may be able to help me. I've also put up a request on an Apache forum. But if anyone here has a lead I'm all ears!
OK, maybe not really maintenance but I am curious if anyone has tried the GoTow tug that is powered by an electric drill? I had never seen one before. My hangar neighbor (who has a Piper Arrow AND a Pitts!) had a "tug" that is powered by a drill. Very neat! In looking for it online I only see the GoTow Tug. You have to buy a Piper adapter. Just wondering if anyone else has tried this and liked it. My neighbors seemed pretty pleased with it.
Do you have a part number for the friction knob? Or a picture of it.
As has been typical so far with 89P we made progress but not as much as we hoped. We did some nice paint work on the panel and interior and when we put everything back together we couldn't find the throttle friction knob. Sigh...
I took the plane up for one spin around the pattern. Not a great idea as the props kept creeping forward to full rpm. And one prop is overspeeding. So for now no more flying until we find the throttle friction or replace it. Then we can deal with setting the prop governor properly.
Everything else look good and engine ran well, no leaks. We have a few more punch list items to knock out so we can still get a few more things done but this plane wants to fly!
Picture is of the plane parked on the side of the ramp next to my mechanic buddy's 182RG (in background). He is doing some major upgrade work on his plane so I parked next to him to consult on our next move while he was working on it.
Even with just one turn around the pattern I got a nice comment on the UNICOM from someone on how nice the Apache looked. At least that was encouraging!
Congratulations on getting your medical back! What an ordeal. Hope it's all smooth sailing (or flying) from here on.
Always a bump in the road somewhere.
You'll have fun.
After 10 1/2 months (who is counting??) I finally have a piece of paper in my wallet that says I can fly! I got my medical today. Thought it would be yesterday but we had one more "bump in the road" before getting it done. The FAA had incorrect dates on the Special Issuance and we had to figure out how to deal with that. So.... My mechanic buddy is flying home from San Juan, PR tomorrow. He is going there to visit with his wife and MIL as the MIL is in hospice. Once he is back we just need to finish the paperwork on the annual and I am back to flying the Apache. At least I hope so. So far not much has gone as predicted!
A few answers from our February One Question Survey --
Articles regarding new products
The magazine which highlights the important information about our "type" aircraft. And the web site too.
All the knowledge I gain from reading the magazine.
I'm a new owner (3 years) of a Warrior and each month I learn a little more about my aircraft and what needs to be fixed or upgraded. AND...I love the monthly laughs I get from reading Kevin Garrison's articles.
As a new pilot and hope to be plane owner, the association does an excellent job of providing general information related to cessnas
The step by step technical projects articles. The text book instruction articles regarding flying.
Opportunities for social interaction with fellow Cessna owners.
Availability of info on the Cessna that I rent.
The magazine - especially Kevin Garrison's column!
Practical discussion of chronic Cessna aircraft issues.
Being part of a like-minded community with the same (aging aircraft) interests.
Access to information pertaining to vintage Cessna 172's. The links, web addresses, informative articles, and AD awareness. Great job done by the staff! Love the magazine!
Everything. Especially Jen. She is the best. Kent is pretty clueless, but what would you want from a Canadian.
That's good news.
I'm glad you asked the question--I hadn't heard to Precision before I started searching.
FWIW, When I talked to Kim he told me that the parts would not be painted when they were returned.
Hi Thanks for the pointer.
I spoke with Kim there and he said that they can do the work.
Since we might be the first Aztec part he has repaired it would take a bit longer as they would ship the part to an engineering lab to test the materials and then he would have to do some FAA paperwork to get the part number added to their approved list. Once that was done then they could do the work and ship back a yellow tagged repaired part. As the first guy it would be about a month start to stop for the engineering, faa, and repair work.
The next person would have a much shorter period of time....
Kim seemed knowledgeable and the pricing was reasonable (in aircraft monetary units).
Trunnion would be around $1200. The collar would be around $350
These are March 2021 ESTIMATES...
The best information I could find is this company:https://www.precision-welding.com/trunnions.
Their website says it has approval to do many Piper Trunnions; unfortunately I didn't see the Aztec on there but I would call them and see if the website is out of date.
I would start by checking to see that the valve core is the correct type.
There are two types of valve cores--the kind that is used in tires and the kind that is used in struts.
The ones used in struts have a little "H" on the plunger pin. H for high pressure.
After servicing a strut I always spray soapy water around the bottom of the trunnion where the strut comes out and around the valve core.
Obviously bubbles signal a leak.
If no bubbles how up at the core or strut, then spray down the trunnion.
I was going to say Granville, but you've already done that.
It's certainly possible that the O-ring seal was damaged during installation. If you can't find any leaks, that's the next step.
Let me know what you find.
I would next check for air leaks through the holes in the fuselage skin at the fuselage-to-wing junction.
The flap control rod (on each side), the aileron cables, the pitot and static tubes and the fuel line from the fuel tanks (on each side) go through these holes.
The fresh air vents/shutoff valves are all functional. These are the 2 grills that are on the front face of the bench seat that (should) take air out from the cabin, thru the battery wing box and discharge from the vent hole in the belly, instead it’s back flowing in thru those non-closeable vents.
Further info, today I taped off the leading edge fresh air inlets on the inboard wing (the inlets you mentioned) the backwards airflow is still there, question is, where is it coming from?!
Hello, I'm wondering if there are any places that can repair the nose wheel trunnion for a D Aztec.
The one I'm looking to buy has damage from being turned to far left and right. probably ground handling mistakes.
Great news. Keep us informed.
Hi Eric, Congratulations on your Special Issuance! I know you have been waiting for that. Good luck on your 1st Class. Back to work.
Finally the good news I have been waiting on... The FAA has approved my Special Issuance for my medical. I'm scheduled to take my FAA 1st class on Monday. So the first thing I will do is call the airline and get off sick leave. Second will be to fly the Apache (at least once the weather is good enough!).
