    chronically low vacuum indication

    Regardless of fitting type the gyros it appears you have did not exist yet. Your’s fits a 3 1/8 in hole which is same as asi, roc and alt. The then popular “ AN Gyros” were rather large with a bigger hole for the AH and a smaller hole for the DG. IIRC they did not need as much vacuum as...

    Bolt torque

    Hope this is not on a Connecting Rod! AN 320 (shortie ) is for shear.

    chronically low vacuum indication

    Just in case you decide to replumb; you may want to consider the fittings. Preferred vacuum fittings do not have an abrupt 90 degree bend. Instead they are radiused and allow air to flow smoothly around the bend. And they are $$$. You do not want to pull existing hose off. Cut it...

    chronically low vacuum indication

    I don’t think I said that! Several ways you can plumb the Venturis. I have teed 2 of them together and have 1 relief valve. They can also be connected using a case as a junction. Important = Inlet hose goes to filter. Vacuum hose goes to Venturi / Relief Valve

    Starter recommendations?

    It’s not unheard of to have problems with the engine not starting with a Starter that cranks the engine faster. This was made infamous with the earlier O-235 L2C as in152. Lycoming actually has a chart that shows the faster the engine spins the more “ Starting Timing” is retarded...

    A&P Schools in Fun Cities

    IIRC at one time Duell Tech ( ?) was located in a prison.

    Hyd leak under cabin fuselage on piper Apache pa23-150

    Hmmm. Since a lot of IA’s are ROGs ( real old guys) it just might be possible that someone might not be an A&P ( Airframe & Powerplant). Could they still be an A&E ( Aircraft and Engine aka Anything & Everything?) Would they have been required to change during the CAA- FAA transition?

    Hyd leak under cabin fuselage on piper Apache pa23-150

    Isn’t the Brake and Hydraulic System Reservoirs in that area? Could they have been overfilled? It’s been a while but I seem to recall the landing gear must be up to properly service the Rez. Will it puke out if done incorrectly?

    Cessna Generator Troubleshooting

    I agree with Dan’s comments. On some aircraft it would be easier to just keep the existing 20 amp fuse and not change the Power Lead. HOWEVER; this could result in “ someone” later changing the fuse to 50 amps. End result could be 50 amps going through a wire designed to handle 20 amps...

    Cessna Generator Troubleshooting

    The Agency that signs off the installation bears the burden of assuring compliance with all pertinent requirements. If this does not take place the aircraft would not be in Airworthy Condition and the Tech may be given a violation notice. My guess that how it happens is that the Owner...

    Cessna Generator Troubleshooting

    IIRC The Instructions do not include a updated wire size. You are referred to AC 43.13- 1A instead.

    Cessna Generator Troubleshooting

    Fast The Alt upgrade is a nice change but please don’t describe the install as “ simple”. It does require skilled labor hours. What method did you use for the connection at the Bus? I have seen Installations where the wiring originally designed for 20 amps is now required to handle 50 + amps!

    Carburetor Intake Cessna 182

    All aircraft that utilize a flex duct to the Carb require careful inspection. That includes some Cherokees, 172’s , Citabrias and Mooneys. There are at least 2 failure modes that come to mind. 1. Collapsing of the Intake Duct. 2. Ingesting parts of the duct or gasket into the Fuel Metering...

    Carburetor Intake Cessna 182

    That is a CRITICAL item. IIRC there is an old AD that required checking the gasket for security. Unfortunately ; it is a “ one- time inspection “ to assure the adhesive is doing it’s task. Worth checking every time the cowl is off.

    From pilot to A/P?

    My belief is that anyone that gets involved in aviation maintenance of any sort should log ALL of the time involved. This includes technical research , ordering parts and diagnosis etc. that an A & P would normally do. Let the Fed Folks determine what can be used if you decide to move...
