As a retired USAF Technical Instructor and Former Training Center Superintendent I can say you would do very well in the Air Force. We need all of that "Attention to Detail" when working on F-16s to F-22s. Aim High!
Double or Quadruple Kudos for you young lady and also for your videographer. I admire airplane mechanics because of their complexity in knowledge and also because the lives of the people who board them, depends from it. But you, being a young female and with that passion and knowledge for airbirds to do hands on services that are allowed by the FAA, is commendable. I am not a pilot nor a mechanic though, but maybe someday i'll be in a plane serviced or flown by you and i'll feel pretty secured. Thumbs Up!! make more videos...!!
Worked and maintained this 150 back in 95 in Wenatchee , had it painted also after etch and alodine, glad to see it still lookin good and in good hands
Nice work and good methodology. It is important to torque fasteners on one smooth motion, at least for the lasat 40% or so of the torque. A couple of times it appeared that you ran out of travel just short of reaching the required torque and then ratcheted the wrench to finish with a very small swing. This can give an incorrect torque, either low or high. Static friction is often 20% higher than dynamic. So, if you stop within 20% of the final value, the fastener may not move at all when the wrench is repositioned due to the higher static friction. Similarly, if it does move, but is close to the final value, the sudden movement when static friction is overcome, can cause the value to overshoot as the wrench reacts. Better to tighten to 50-60% of final torque and then reposition the wrench to ensure that last bit of torque can be applied on one smooth, continuous motion.
Nice to see a girl not scared to get dirt under the fingernails, great video and explanation Maria, you have a new subscriber and I look forward to seeing more 👍
For what it’s worth remove/loosen the oil filler cap when you release the quick drain the oil will drain faster plus it’s a second reminder with the cap off/loosen
Hello lady , you are one good , motivated and careful mecanic on that plane . Fantastic , i'm in awe . I wish you succes and good luck on your path of aviation . The same remark goes for the girl who was filming , good job at that . One remark , when you turn away from the camera your voice-level drops away , and i cannot understand you anymore . But i really liked the two video's on this 150 aeroplane maintenance job . Are there more ? Why don't you make video's of all the maintenance jobs allowed by regulations to be done on the private aeroplane by the owner . I would like that to be done by you , in this here same clear-minded and well commented manner . A good mecanic works more with the brain than with the hands , and that is what you do . Very good job lady , congrats , Erwin , Belgium .
Great video. A few suggestions: Eye Protection, spark plug removal ratchet tool (same brand), shorter extension when tightening with a torque wrench, more the 1 1/2 in extension affects the reading of the torque (Check with the Tool Salesperson) and when removing fasteners, plug, etc. You are suppose to push on the tool away from your body.
No, a socket extension doesn’t change the torque value when using a hand wrench. It doesn’t affect if you are using an impact wrench, but using quasi-static force application will not cause errors.
good video.... In this case, probably OK, but in general, bad practice to ratchet with a torque wrench, especially at higher torques. Get it close with a ratchet....dial it in with the torque wrench.
Really interesting that the oil filter is safety-wired on but not the spark plugs or HT leads. Or the oil filler cap. Maybe oil filters are untrustworthy. I know mine comes off once a week.
Dielectric grease is of course non-conductive, and you don't want it between your conductive surfaces. In an *automotive* application, you coat the inside of the spark plug wire's BOOT and take care to not apply it to the conductive end of the spark plug (the non-spark end ... the end that looks like a nipple of sorts). This might differ in an *aero* application, but I'd be surprised. Technically it is OK to use dielectric grease on conductive surfaces if the grease is wiped/pushed away as the conductors make contact (many electricians swear by this when installing fuses), but this requires very tight connections. This is why you will see a lot of debate re: whether or not to use dielectric grease on conductive surfaces: those who say it's OK often are not aware that an extremely tight connection might sufficiently push the grease away, or take it for common knowledge and do not explicitly mention this fact. Edit: here is a video I found on RU-vid that explains this a bit better. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Kb1VldFpRG8.html
@@christophermichaelson9050 Yes I agree nothing solid and where is it in class where they would tech it. Where connection is most important example ignition systems I would go out of the way of direct soldering and weather proofing the solder connection. spark plugs knowing the connection is a pressure grip type (pressure dimpled) I use it at contact point and all thru the boot and even the insulated wire to the boot to prevent water to make a path for high voltage to travel to. High pressure contact yes under very high humidity and water conditions where h2o and o2 is sealed from. Me not knowing I was just wondering if it would pass inspection for flying using the dielectric grease? I forgot to add that in my question. Thank you for the reply and on the same page in the mater. one of my favorite is the colt dragoon, colt peacemaker
Nice video. You did a nice job until you started tightening the leads. ALWAYS COMPLETE ONE OPERATION BEFORE STARTING ANOTHER!!! When you tighten leads tighten all of them before you start another operation. I'd be fired for tightening one lead and then adding oil and then going back to tightening another lead at the shop I work at.
I'm curious as to why you wouldn't set the propeller north to south when you began the service so you didn't have to keep on walking around it. I also noted that you did a lot of jumping about as far as the steps in the procedure such as sealing the oil drain plug before torquing the spark plugs, etc. You made many movements that could lead to a mistake. It also took you extra time to do the service because of the excessive movements around the plane. I am an Automotive Tech with 50 years experience. Being constructive, not trolling :)
You said it takes six but I only saw five containers. Also, doesn't the 150 have a sump capacity of 6 quarts but the total oil capacity is 7 quarts including the oil filter?
There is no correction for a straight line extension www.snaponindustrialbrands.com/dsn/wwwsnaponindustrialbrandscom/Content/PDF/CDI%20TechAngle%20Manual.pdf
Vinny: Maybe you didn't twist it hard enough. Mona Lisa: I twisted it just right. Vinny: How can you be so sure? Mona Lisa: If you will look in the manual, you will see that this particular model faucet requires a range of 10-16 foot pounds of torque. I routinely twist the maximum allowable torquage. Vinny: How can you be sure you used 16 foot pounds of torque? Mona Lisa: Because I used a Craftsman model 1019 Laboratory edition, signature series torque wrench. The kind used by Cal Tech High Energy physicists, and NASA engineers. Vinny: In that case, how can you be sure THAT'S accurate? Mona Lisa: Because a split second before the torque wrench was applied to the faucet handle, it had been calibrated by top members of the state and federal Departments of Weights and Measures, to be dead-on balls accurate. Here's the certificate of validation! Vinny: "Dead-on balls accurate"? Mona Lisa: It's an industry term. Vinny: I guess the ****in' thing is broken!
Fuel should already be cut off, Master Switch doesn't matter, and mags don't matter because none of the plug wires are connected - although off is better.
A straight extension used between the socket and the torque wrench does not affect the torque setting A universal used on a straight extension may not exceed 15 degrees Any tool that changes the distance between the centerline of the fastener and the torque wrench requires an adjustment to the torque wrench setting Ref: amt general 7.51 and snapon torque wrench manual
