What are the ramifications of over torquing a bolt? AN6 with a castle nut is spec’d at 44 ft lbs but the called for bolt length is about 1, maybe 2/6 of a castle too short for the cotter pin. I know what I am going to do but I would like the collective opinion about using the spec’d bolt and...

Generally accepted practices for installing bolts is to follow the “IDA” philosophy. In, Down, or Aft. On my motor mount, the bolts through the firewall were installed from the inside, opposite of that. I kind of like that idea because they are easily looked at during preflights. The...

I was contacted by a lady who has hydrocephalus. She saw somewhere that I had had hydrocephalus. But unlike my case, hers is ongoing. She wants to become a professional pilot. Is it possible for her to get a First Class medical? She did a consultation and was told that it would get...

Just for my general fund of knowledge, what items do an engine logbook cover? Are any of the accessories included or are they part of the airframe logbook? To add on with a specific question, would the replacement of the rubber engine mounts and related hardware be logged in the engine or tha...

How shallow into a castle nut can the cotter pin be before one must add a second washer?

In the interest of reducing the current draw on my 25 amp generator, I have replaced all of my lightbulbs with LED replacements. I have a Whelen nav/strobe combination and my panel lights are dimmable with an appropriately compatible rheostat. When I turn all the lights on an “interesting” thing...

The Stinson parts catalog specifies AN6-36 bolts and AN310-6 nuts plus cotter pins for the motor mount. What is currently installed is AN6-36A bolts and the all metal lock nuts that I can’t put a number to just yet. Is there a reason why someone would have used something other than the bolts...

I am trying to come to grips with what is required in an engine compartment. Specifically, I need to secure spark plug wires. Since it is in a high heat area, is there a specific clamp that is required? Are they color coded? Looking in the Spruce catalog, it appears that I need to use either...

Wandering around Oshkosh yesterday I ran into a couple of guys I know that mentioned they were REQUIRED to get a third class every year. IOW, no basic med. Is this true? If it IS true, at what age does that requirement kick in?

Anyone have one? Pilot report? The good, bad, and ugly?

I am looking for a ‘40’s era altimeter for a Stinson 108. Specifically, I need one with the baro adjustment knob in the six o’clock position. Anyone have any ideas where I can find one? Yes, ideally it should be in reasonable working order. Thanks.

I am looking for a dimmer switch for my panel lights that has an off position. Currently, the panel lights are on the nav light circuit. Since nav lights should pretty much be on all the time, I would rather the panel lights be turned off when not needed. My current solution is to put the panel...

I need to install an ELT antenna on my Stinson. As I understand it, the ELT antenna should not be placed within 36 inches of the Comm antenna. However, there is already a mounting location on the airplane but it is 33 inches aft of the Comm antenna. How critical is this spacing? It is...

I am having issues with the 2-step verification on my iPhone. I enter the code, it indicates all is well but then it rolls right in to needing 2-step verification again. I am not sure whether the issue also affects my iPad because my current login hasn’t expired yet. Help!

I am not a fan of posting anonymously especially when the subject does not affect me personally. In this case I am truly asking for a friend. My friend is a Private Pilot, albeit non current at the moment. It has been several years since he has had a medical but he has the option of going...

Our 150/150 tow plane developed a pretty much irreparable crack in the spinner. Sourcing a replacement is proving to be problematic. As near as we can tell, the spinner is a MASA/Doyn 2512. Never heard of such a thing. For what it’s worth, the STC number is SA527CE. Apparently, the STC...

I am on the southwest corner of Aspen and 23rd, green and yellow tent. We will be here until Thursday sometime. I probably won’t be at the sight much. My cell service here kind of sucks, but my phone number is 816-589-5044.

Anyone here familiar with any Missionary Aviation organizations? I may be interested in flying for one in my retirement, but don’t really know anything about them.

@bbchien JOOC, what are the FAA medical ramifications for a cancer patient? I assume that the medical is invalid until cancer free, but is there a period of time after being cleared that one has to wait before being certified?

Hey Ron, are there any Fly Baby biplanes actually in existence? I know it was an option and at least one was built but I never see any mention of it.
