The Cub trim jackscrew is removed from the top . The hole for access should have an aluminum cover plate that can be removed for access. The TriPacer trim jackscrew comes out from the bottom of the trim assembly mount. I have to slack the elevator cables to gain access through the belly...

My opinion would to be, “run Forrest, run”. First of all, is a lack of integrity by someone in the ownership chain. Second, I have personal experience with this sort of issue. Thirty years ago I had a 1939 Luscombe that I restored along with its Continental C-65. There was no notation in the...

My TriPacer is a 1955 model and it looks like the engine mount had a bracket welded on both sides to take the early aircraft muffler support rods assemblies. I just need to find a drawing or pictures to source the items required. I am on the road so I do not have access to our drawings flash...

During my flight from Oregon to Florida I had the left exhaust pipe break. The break was about 1/8 inch aft of where the #4 down pipe enters the collector pipe. I was fortunate to be only 5 miles from a suitable airport. The pipe was broken completely in two. The weight of the muffler...

Anyone planning on S&F this year? I am leaving Oregon this weekend and heading for home in Florida. Looks like the South route due to wx. Put a couple hours in yesterday for the initial break in of the newly overhauled engine. We hope to have the TriPacer there, if not, we will definitely be...

That is why I clarified my answer that if an item was added after original certification. If it was added via STC, 337 or other approved method, it now becomes legally part of the aircraft and unless you have an approved MEL or CDL for that item on that aircraft, it has to be operational for...

Mark, we will have to agree to disagree. Using your line of reasoning, you have just saved all the rag wing Pipers a lot of money. The rudder is not called out specifically in the Piper TDCS either. Just remove it and fly away. No rudder AD to comply with since there is not a rudder...

Steve, the early O-290 and O-320 pushrods used a number of grooves around one end of the rod to indicate length. These pushrods did not have part numbers on the pushrod. The number of grooves ranged from none to three grooves. I do not remember whether no groove was longest or the three...

Does anyone know the length dimension for an O-320 pushrod with one groove? I have misplaced my old Lycoming information packet. Thanks! Blue Skies, N2709P

Steve, the information is actually contained in what the FAA calls a “Handbook”. They used to be called an Advisory Circular. This handbook is FAA-H-8083-3C , Airplane Flying Handbook. The hand propping advice is in chapter 2, paragraph 16. Every pilot of all levels should have this handbook...

The FAA is very specific in their AC that they consider hand propping to be a TWO person operation. This means a qualified person in the cockpit, even when the aircraft is properly tied down. Anything otherwise is considered by the FAA to be “careless and reckless operation”. They will write...

There can be a big difference between “repair as necessary” and “Overhaul”. Overhaul requires replacement of all parts and testing as required by the manufactures overhaul manual specifications and requirements. Repair as necessary means that the unit will be inspected and repaired. Defective...

You are only talking a gain of 20 or 30 knots on the TriPacer over another reasonable priced aircraft unless reasonable priced includes turboprops or jets to you. Not enough gain in my opinion to make it worthwhile. Anything over three hours, we buy an airline ticket. It is usually quite a...

I am not quite sure how disk brake STC’s get approved on Pipers with the original Cub type master brake cylinder. The original brake systems are non-vented. Disk brakes actually need a bit of disk warpage to keep the brake pads off the disk and keep the heat down. The heated and pulsed brake...

If I remember correctly, my original rivets in that area were steel tubular rivets. I replaced them with keyed rivnuts and stainless 8-32 washers and screws. In fact, all the belly pan screws are the same. It takes about 10 minutes to remove the belly pan for maintenance and inspection. N2709P

Steve, please remove this thread. In fact, please remove my supporting membership. Regards, Ron

Sorry about the extra pictures! I am Fred Flintstone in George Jetson’s neighborhood. N2709P

Finally finishing up the new interior installation ( I know, it has only been a year ) and am ready to install the rear seat belts. The outboard attachments are obivious but the center attach point does not seem correct. The attach fitting welded to the airframe for the center seatbelt end...

Flew thousands of hours behind those AN gyros in BEECH 18’s, DC-3’s and AT-6’s. Even my 1958 Comanche had the AN gyros. The ones from WW2 had bronze bearings and were bulletproof. The “new style” 3 1/8 inch gyros were junk back then and I did not trust them for hard IFR. The pin is just a...

Sorry, I misunderstood your issue. Yes, there is a retaining nut and a shim washer on top of the upper bearing. The upper and lower bearings are usually in pretty poor condition. I soaked my assembly in penetration oil and then used a press and mandrel to remove it. I also had to use a bit...
