Airworthiness Directives (ADs) Research | Cessna 140 Annual Inspection (Part 1) Part 6

[@kevintaylor791]

Great video. I agree that the seat belt AD solution is kind of funny in it simplicity, but the serious reality of it is if that bracket was made of aluminum and you had an accident, the seat belts are far more likely to fail at that bracket. If that bracket fails the belts will not keep you in your seat. If something happens that breaks that bracket... you probably REALLY needed it not to break in that moment.

Thank you! Im still learning but loving it!

Now is the research so long because you don't have the logbook records? If you did would that research be done by looking at previous logbooks? I guess I am just curious as to how to make that process less cumbersome. Just seems like there could be more filters or something that could help you search those documents to get rid of any that doesn't make sense.

[@The_Flying_Mechanic]

Basically not having any records just means that everything that I got with the Aircraft needed to be thoroughly looked over. When I talk about research in this video, I’m really discussing the fact that I want to make sure that all the airworthiness directives were completed on this Aircraft, even if I don’t have the paperwork for it. I was very fortunate to find that in a later video, even though it was partially destroyed.

[@DucttapesUnicycle]

Any component that has a serial number can potentially have an AD.

[@The_Flying_Mechanic]

That’s right! That’s why it take so long to do the research! I discussed some airframe items mention other stuff like carbs and mags as well that I reviewed. It overall took about 20 hours of time to research… probably 15 if I wasn’t messing with a camera the first little bit of it.

Does 47/43-06 apply? I want to see a video on doing that one

[@The_Flying_Mechanic]

The ribs supporting the ailerons were too weak on the batch of 120/140 manufactured from SN 8000 to the mid 10,000. Mine was a few months after the AD came out and it doesn’t apply to my aircraft but per the AD you have to do an Inspection required whenever airplane is tied down in high winds without controls locked and upon each 100 hours of operation until Cessna parts 0422200-2 and 0422200-3 are installed.

[@richarddavis9895]

Do you have inspection holes in the wing?

[@The_Flying_Mechanic]

Yes! I have a drag wire AD that required a few holes to be installed.

[@richarddavis9895]

How about a hole at the outbd aileron hinge?

[@DucttapesUnicycle]

7:35 what about rebuilding completely lost logs?

[@The_Flying_Mechanic]

A lot of mixed opinions out there. Fortunately only about 10 years of records from the first part of its life were lost. I recommend discussing options for completely lost logs with both the FAA representatives at your local FSDO and experienced mechanics. I did both even with my partial logs. It’s definitely not a deal breaker (depending on AD/time limited parts) but is a time consuming expense that sometimes isn’t worth rebuilding the logs. This was almost the case with @rebuildrescue 401 project until he found the logs.

[@DucttapesUnicycle]

@@The_Flying_Mechanic yeah a friend of mine keeps talking about buying his own plane and asking me to look stuff over(I’m an a&p but no IA yet.) a lot of the aircraft he send me have zero logs.

[@The_Flying_Mechanic]

@@DucttapesUnicycle if you want to do IA I can highly recommend Bakers School of Aeronautics in middle TN for the prep. I did ASA and failed the test with a 62%. I took a trip to Bakers and made a 100% on the retake.

[@DucttapesUnicycle]

@@The_Flying_Mechanic I was already planning to go back to them for my IA. I did my a&p testing with them. Got my 8610-2 through military experience.

[@The_Flying_Mechanic]

@@DucttapesUnicycle lot of guys I was with in IA class did that too. I did a Part 147 school for A&P and then their IA course.
