- The borescope is one of the most important and versatile tools for inspecting GA aircraft, and is the gold standard for assessing cylinder condition in reciprocating aircraft engines. However, aircraft and engine manufacturers have provided no guidance on how to perform a proper cylinder borescope inspection, and A&P training doesn't cover it. In this webinar, Mike Busch A&P/IA discusses what his company (Savvy Aviation) has done recently to fill this vacuum. Savvy has developed a detailed inspection protocol, produced a 35-minute training video demonstrating its use, and published a companion checklist with detailed descriptions and examples of each image to be captured. In addition, it has created a sophisticated Web-based borescope image repository available free to anyone wishing to use it. This repository allows borescope images to be uploaded, tagged descriptively, archived, annotated, and produces elegant PDF reports. Savvy Aviation offers Professional Maintenance Services to owners of General Aviation aircraft, such as: SavvyMx (Professional Maintenance Management including Prebuy Services), SavvyQA (Expert Consulting), SavvyAnalysis (Engine Data Analysis) and Breakdown Assistance. Savvy also publishes a monthly newsletter with lots of interesting information for the general aviation enthusiast; subscribe to it at www.savvyaviation.com or text the word "Savvy" to 33777. This webinar was hosted by the Experimental Aircraft Association (EAA).

I can’t wait to submit my photos at my upcoming oil change. Just got a borescope. Thanks for this.
Hello Mike, I want to start by saying I really enjoy these webinars, as a private pilot shooting for the airlines, an A&P in training, and an aspiring future aircraft owner.
I think you will be happy to hear that the aircraft maintenance school I’m attending is starting to adapt a lot of what you say about borescopes in the reciprocating engine portion of the program, with the 11 requires photos, and borescope techniques. 4 Nvidia borescopes have been purchased and received by the school, and will be put to use in future semesters. The school is also starting to make written and practical assignments based off your Engines book, which I have read a good three times now.
I’m one of the few people in my class that actually enjoys general aviation, and reciprocating engines. And even though I want to fly for the airlines, I want to be as involved with GA as possible throughout my career.
Thanks to Dave who taught me how to do this 6 years ago as a Savvy client
One person asked about compression test vs. borescope as related to predictive capability. I would argue that if a compression test is correct it can only tell you that there is a problem because the cylinder is now leaking excessively. One of the huge benefits of a borescope inspection is that you can see evidence of problems developing before they become so bad that the cylinder leakage becomes excessive. For instance, if the heat signature of the exhaust valve is not symmetric you can tell that either it isn't rotating or it isn't making sufficient contact with the seat all the way around long before it starts leaking so badly that it fails the compression test. Similarly, you can see deposits building up on the valve stem before the valve starts sticking. A borescope inspection enables catching problems and fixing them early with much less risk and cost. By the time a compression test tells you there is a problem, if the result of the test is correct (often not the case) then it is more likely too late to implement the low cost low risk corrective actions.
I find it fascinating that there are problems associated with jug replacements. Please explain to me why a jug replacement procedure is any different than the original assembly of a new engine.
Smart to give away all this for free so you can build the predictive analytics engine on this. Data and images is the real value.
Hi, Guys, I’m an Part 121 Captain and I’m really confused about the overall process of an Defect Deferral, mainly Other then MEL/CDL/NEF are used such as the AMM, or the Engine LMM, etc.
Tip: Only borescope a cool engine, otherwise the heat will create a lot of video noise in the VA400 camera sensor.
And melt the little rubber cover over the hinge.
This would be a great way to collect tons of data comparing 100LL with unleaded alternatives. You'd probably want to categorize the data by make/model of engine, and the most recent type of gasoline. This might help us find winning combinations of (certified or uncertified) engine and fuel.
Regarding AI diagnostics, would there be any value in adding spark plug photos?
On the topic of compression tests, wouldn't it provide a more complete picture by adding cranking (dry or wet) compression tests to this leak-down compression test? That's what automotive mechanics do. Leak-down only tests the sealing at TDC.
Do this every oil change when you rotate the plugs
It's about 27.5 acres. No wonder you were tired.
Why don't we stagger mag checks? Always both off and the same time and out for 500hr IRAN. If their both working, send one out. After it's back and then another 100 hrs send the other one out.
I'm sure you can do this - just do the first one at 400 hours, then the next at 500.
It's a shame we can't get faa credit for watching this after the webinar. It should not matter as if you ask a question during the webinar, they never ask it anyway (unless the webinar holder is interested) and that is the only difference!
If this is needed for you to meet that requirement I would suggest you don’t do enough training
@@AlanOnCA This a stupid reply and is sarcastic your honor as it does not address my statement! But you have a nice day .
So I posted some info on where to get a good articulating borescope for $50 bucks, £36 but CZcams didn’t like it and they got deleted.
However if you have a surf on a certain website you’ll find them.
I’ve bought two and they were very good, as good if not better quality that the $300 ones that Mike is talking about.
China is the place for cheap Tech. The ‘Express’ company have local warehouse so delivery in the UK is quick. Must be the same in the US, preface is ‘Ali’
Any further hints on which specific product from Mr Ali?
Do you have a model number Clive?
There could be spare bolts assembly down there Mike tell them to image everything... All the time... Boeing dose the spare bolts through out the aircraft all the time it must be the new assembly not complete
Mike, Great work as always! A small note for you....this is not Artificial Intelligence. This type of analysis.... is something that has been around for while. This is business intelligence, trend and predictability analysis. I have been building intelligent systems for more than 14 years. the latest buzzword is AI. I hope no one is over selling you a bill of goods. Any way great work! (I am IT professional for 25 yrs and a pilot)
