  1. until

    Michael, I'll join if the weather permits. You may want to create a new thread in the General Aviation Talk section, as I found this event completely by accident. Thanks for initiating a future event. Regards, Jon
  2. I lost a center electrode on a Tempest FW. During the search for the electrode--borescope, oil change--there was evidence of it bouncing around in the cylinder before escaping. We didn't find the electrode in the engine or oil but several A&P's were of the opinion that it escaped via the exhaust, as it was too large to get past the multiple piston rings. I've had two oil changes since and there was nothing but carbon in the oil when strained. I agree with my A&P's assessments that it escaped via the exhaust. Tempest sent me a replacement plug but did not tell me if they were going to conduct a failure analysis. If Tempest did, I would doubt they would share the report. I've got 62 hours on the new plug and close to 200 hours on the others. Time will tell regarding their longevity but I now have a spare, just in case. I would buy them again, as I had fouling problems with my Champions. My engine ran smoother, hot started easier, and I've yet to foul one.
  3. @Alfredo, Glad you figured out your issue and got down safely. Also glad you joined the forum and started asking good questions, as I learn along with you from the tremendous knowledge-base of MS. I can't speak specifically to your alternate vacuum issue but this is why I replaced the electric turn and bank coordinator with a Garmin G5. I replaced the T&B due to my observation of the AI and the T&B during vacuum failure, while on a VFR flight. The AI was down right dangerous and the T&B bounced all over the place due to turbulence. I believe the Bonanza pilot Paul @kortopates mentioned had a T&B in place and still perished. As others have mentioned on this thread, it sounds like there is an effective way to use your installed alternate vacuum source in your recent scenario but as @Marauder pointed out, it may be safer/better to go a different route. E.g. approved EFIS AI replacements or other dual function products that provide AI functionality such as the AV-20 or AV-30. Just adding my 2¢ to a good conversation.
  4. A future aerospace engineer and pilot if I ever saw one!
  5. Mine stayed the same and I had a switch to Global.
  6. José, ??? The link let me too all kinds of electrodes but I don't see the ones with missing electrodes. Someone more knowledgeable than I will have to tell us if your concern for what damage a loose iridium wire might possibly do. (I did have an engine "swallow" an exhaust valve years ago. The head of that valve, which was hundreds of times larger than a plug wire electrode, did beat up the cylinder and piston surfaces pretty badly but did not interfere with the stroke and I still had 3 cylinders producing power and no oil loss.) You seem to like anecdotal evidence. When I bought my E the previous owner had been running massives. About half the plugs had been replaced and he carried 2 back up plugs in the plane just in case. I replaced the plugs with fine wires within 25 hours having had enough with fouled plugs and hard starting. I only bought 8 plugs, now 6 years old, and I no longer carry a spare. The 8th picture from the left in the link is mine. I lost the electrode following my EDM900 install and the subsequent pre-flight testing and runups. During the search for the electrode--borescope, oil change--there was evidence of it bouncing around in the cylinder before escaping. We didn't find the electrode but several A&P's were of the opinion that it escaped via the exhaust and that it was too large to get past the multiple piston rings and into the engine. I've had two oil changes since and there was nothing in the oil when strained. Judging by looking at the piston cylinder wall and marks in the top of the piston during the borescope, I would agree with the A&Ps assessments that it escaped through the exhaust. Tempest sent me a replacement plug but did not tell me if they were going to conduct a failure analysis. I've got 60 hours on the new plug and close to 200 hours on the others. Time will tell regarding their longevity but I now have a spare, just in case.
  7. In the US. According to Mike Bush's webinars, outside of an annual inspection the only person that can ground an aircraft is a pilot/operator who will/can conduct a flight in a given aircraft. Once an aircraft passes the threshold for its annual inspection time-frame, an A&P/IA must have performed an inspection and signed off on the airworthiness of the aircraft. If there is a disagreement and the pilot/owner wants a second opinion. The A&P/IA must document the work that was performed, annotate the outstanding inspection discrepancies--including the airworthiness items--and provide a logbook entry. The pilot/owner is then allowed to do what ever they please with an unairworthy aircraft. Owners can park the airplane or take it to another A&P/IA to resolve the issues. The annual inspection language is the concern of @DonMuncy. Annual inspections have ramifications towards FAA regulations and airworthiness and being able to fly a given aircraft. A PPI does NOT have the same ramifications. An A&P/IA may find something that they feel is an airworthiness item but the only person that can ground an in-annual airplane is an owner/operator, at least until when the next annual inspection rolls around or by a FSDO. One of the reasons for Mike Bush's webinars is to educate pilot/owners, so their airplanes don't get held hostage to unscrupulous individuals who hide behind inspections. If you are buying from a private owner who is willing to let their airplane go under the annual inspection knife then do it. Don't get offended if they don't go for it... As an owner, if I am selling my airplane that is currently in annual, I would only allow an annual inspection for the buyer if they are using a shop that I explicitly trust or my A&P/IA. I would allow and encourage a buyer to perform a prebuy with whoever they choose, but I would not allow an it to become an inspection/opportunity for my aircraft to become grounded in someone else's maintenance facility. If you are buying an airplane from a broker see if they go for an independent annual inspection. I SERIOUSLY DOUBT THEY WILL and will probably not take or respond to you as a serious buyer. Just my 2¢...
  8. GoPro Studio is still available on the Internet. I use Studio for fast editing. Studio is fast, simple, and capable, although it won't handle content from a Hero7 Black. For the 7 Black, I use PowerDirector16 because I got a deal on the software. PowerDirector16 has far more features than I need but that's the fun part of learning video editing and content creation. I have tried VSDC and it seems capable but its features are not at all intuitive and the software is overly processor intensive. The intuitive feature offerings in VDC steer you towards the pro version which requires money, so I have not continued my experiment with VSDC. I'm and old IT by trade and steer clear of subscription based software. Subscription software may be great and have the newest features but sometimes old technology that is owned still does the trick. Especially when that software can be obtained for free such as GoPro Studio or purchased outright. It's a shame GoPro discontinued Studio. It's more of a shame that GoPro pushed everyone onto Quick and pushed their subscription based/online content editing, while at the same time uninstalling Studio without informing the end user. Fortunately Studio is still available for download from other sources. Just be careful and get it from a reliable source like CNET et al...
  9. That's a CB right there... hand propping a $750k to $1M AMU aircraft. Why, why, why would one do that! Unless that one is a Super Cheap B@$t@rD (SCB)!!! Did I just coin a new MS phrase?
  10. Yeah... that's why one of my goals over the next few years is to get my A&P certification. Hopefully, in the mean-time I can keep my wonderful relationship with my current A&P/IA.
  11. I have it mounted with a Helmet Side mount from GoPro at the top leading edge of the vertical stabilizer. I'm 6'5", so it's easy to reach that high. I'll snap a picture of it next time I'm at the airport.
  12. Taken from a Hero7 Black, which is far superior as compared to the same shots taken with the Session 5. The quality of the video and picture is much better than what is depicted here. I have and will continue to use my Hero 3 Silver, Session 5, and new 7 Black to document my flights. It's enjoyable to put the videos together and bolt on music for later viewing. I also find editing and splicing post flight videos a great debriefing tool. I recently hooked up cockpit audio to the Hero3 and now can overlay audio to my videos. The process is enjoyable and definitely helpful in identifying and correcting mistakes in my flying.
  13. Will send you a PM shortly...
  14. @mstephenson51 Welcome aboard and good luck with your PPL.
  15. Mike @rangermb, I scanned it to .pdf with a copier. I then edited the scan with Adobe Acrobat Pro to make it searchable. If you don't have the software but can scan the POH to .pdf, I may be able to help with making it searchable by sending it to me. Let me know with a PM if interested. Tom @ArtVandelay, do you have links and are any of them for a 77?
