Anyone know of a source that sells the Continental injector line hold down clips. I need to replace a few of them but having a hard time finding them as a separate item from TCM. Maybe there is a part number, but I can't seem to find it. Thanks in advance!

My new project is building a 3D model representative of an instrument panel and all of the associated structure that sits behind the panel. Of course I want to populate this panel with accurate models of the various instruments and avionics. Does anybody have knowledge of an existing repository...

A question for the engineering arm of the POA brain trust. I’m trying to understand how an instrument shop calibrates an airspeed indicator and also to find the associated tables of pressures. It seems that this would be very simple if all an airspeed indicator concerned itself with was the...

Noticed my alternator (ES-4011) has a fair amount of movement in the lower bracket attach point contributing to excess vibration and wear. I pulled the unit and examined all of the mounting hardware and discovered several problems as shown. Trying to find an assembly drawing but Hartzell tech...

Back in the heyday of GA a company by the name of Meletron made a variety of pressure switches for pneumatic, fuel & hydraulic systems. These units found application in various high end GA aircraft include some bizjets. My Aero Commander has several of the Meletron switches performing different...

No doubt there are dozens of sealant/adhesives out there, but some must be better than others. I want to install some side windows. Looking for a material that will handle the bonding task but will also allow me to form a nice tapered border to smooth out the step between the aircraft skin and...

Here is my situation: IO-520 with Airwolf remote filter, Hartzell prop, Woodward governor, Twin Commander. During a recent left engine oil/filter change I observed the following… drained the oil from sump – let it drain for a couple of days until it stopped dripping. Then I proceeded to remove...

Had an attention getting experience today. Climbing out some 20 minutes after takeoff the left engine prop on my Commander started running away. RPM surging up and down by over 800 RPM with no warning. This event was not preceded by any power change or other pilot action. Prop control had...

While traveling on a commercial airliner recently I noted how thin yet strong the side panels were. Thickness was about .125 to .156. Panels were formed to match various curves and other features. Anyone know what materials might be available for GA interior use that have these characteristics...

I like a clean and shiny engine compartment, but I’m a little hesitant to get in there with a pressure washer and just have at it. What kind of solvents or cleaning agents are a good solution for keeping things in good condition and how would these be used? Appreciate any help from the collective!

Would appreciate any leads on the existence of a 3D CAD model of a Continental big bore engine. SW or IGES or any 3D format would be very helpful. I've checked on GrabCAD and don't see anything. Someone must have done this?

Anyone have a lead for me on an aircraft moving service? I have a couple of planes that I need moved... one from the Bay area and another from near the Oregon border, both down to SoCal. Aircraft are in pieces so no disassembly required, but it will take a couple of strong bodies to get these...

Planning to replace some hydraulic hard lines (3/16 OD alum). In reviewing all of the videos it seems that they all talk about a double flare, however the old lines that I am replacing all have single flare ends. Also, most of the dies in my flaring tool say "double flare". I do have a 37 deg...

The linkage shown in the attached picture (from Continental fuel control) obviously changes the mixture based on throttle position. This linkage is clearly adjustable along with the idle adjust screw. My question is: how do you calibrate this adjustment and know when it is correct?

The Garmin GI-275 base model is really packed full of a lot of features, including a VFR GPS. It seems like a lot of functionality for the price and can be installed with an A&P sign-off. I’m trying to understand the options – and differences – found in the many small portable GPS antennas...

Anyone using the Teflon fuel hose with the integrated firesleeve? This would be Stratoflex 124J or the Aeroquip equivalent. Any downside to this hose for the 4 or 5 fuel related hoses in the engine compartment?

When an IA performs the AD review as part of an annual, how does he determine if an AD still applies? I'm referring to one-time repairs, not so much recurring ADs. For example several ADs are very old that relate to engine and accessories components, in my case issued long before my engine was...

Any opinions on the best option for flexible brake hose? Replacing 30 year old hoses. When my gear retracts it creates a fairly tight loop so I need something flexible. Thanks!

Planning to replace the pitot-static tubing behind the panel. Looking for feedback on the best materials to use. Is the plastic tubing with the push-on fittings now the de facto standard (such as the SteinAir components)? Are there different qualities of tubing? I just want to make sure I end up...

Many threads have been written about the Century 2000 autopilot, which reflect about a 50/50 split between “it works great” and “it’s a real problem”. A used system does represent a bargain based on its feature set. It is also one of the few autopilots with my aircraft on the STC list. In...
