I think going under the microscope might be preferable to an overshoot into the Shotover 😄

It's in the former Lytton Quarantine station in Brisbane, now national park. Something to do with killing off the bugs on new imports.

Rapid deceleration, I think you'd want your seat belt fastened.

Theis is an open forum..... I'm telling people she's been admitted to hospital.

I caught her once with her hands into the gold so now I keep it secure...

I'm trying to offset the aircraft and training expenses. https://youtu.be/02hW0NyZTto

I'm sure you're right but you are tampering with a well proven design that in most cases has a good service life.

I did it last night. Mrs M is away so I have rare but full control of the remote controls and I failed to take advantage. I was too engrossed in the glossy magazine to be bothered with all the bad news and propaganda found on our TV.

Helical gears produce thrust, it might just be the start of another set of problems.

Anything over a fast idle should have sufficient load from the propeller to take up the slack. Some backlash is need to allow space for lubrication and expansion but any sort of load should prevent the components separating enough to rattle. Most new components will have a certain amount of metal from the machining process and run-in collected in the first filter change but that shouldn't continue to show up.

Yes Sean I agree however it's not that I didn't do it. The may be a little old school but I trust my mercury level more than I trust the modern electronic device although if your gauges are balanced it should do well. Each intake manifold is connected to one end of the tube filled to the required level with mercury. All I have to do is level the mercury so I have it pretty close.

From the Rotax forum; Gentlemen Before everyone assumes in all cases crankcase fretting is strictly a Rotax design issue, please consider there are many influencing factors that ultimately can lead to a certain destructive harmonics being transmitted through the engine, resulting in loss of crankcase stud torque leading ultimately to crankcase fretting! I've seen this issue from time to time in our Diamond Katana Commercial Flight School fleet and in all cases we found it attributable to a series of compounding issues which if not resolved ultimately lead to the fretting issue. Things such as proper carb synchronization, intake induction design influence on mixture settings, worn carb parts such as slide needles, slide bores, float arms, etc., bad engine mounts(worn out, too stiff, too soft, wrong design for isolating first order natural frequency of engine), poor engine mount design(again fails to totally isolate engines first order natural frequency), propeller balance and tracking, mass inertia, blade flex influence etc., gear box maintenance including friction torque settings, gear dog spring pack pressure etc., and gear box gear wear(pitting caused by poor oil quality with inadequate zinc content to prevent gear tooth pitting etc.). As well, and as important is prop loading. Many people are over propping their engines by adding too much pitch, in essence running to high a gear(too much load), for the amount of throttle they are loading the engine too! I've seen a lot of chat on this site about prop loading and can tell you one rule of thumb that works for one aircraft/prop/engine combination may not neccesarily work for another as there are many floating variables here also. Too many people run over square on engine load versus throttle setting like running your car in fourth gear with a boot full of throttle trying to climb a steep hill when they should be in second gear! The Rotax 912 series can run it's entire life wide open throttle at 5500rpm and will love you for it and at this loading has the absolute least natural engine vibration! Lastly, if you are sure you have discovered a safety issue with your engine, you can file a Customer Service Information Report(CSIR) by going to the "Service" button on this web site, then scroll down and click on "File a Customer Service Information Report". Make sure you fill in completely this form with all required information and then submit it. Copy of your submission will be sent to the factory and the other to the applicable Rotax Distributor in your area but only if it is deemed legitimate and not a fart in a mitt! Upon submission you may be further contacted for more information and follow up depending on the issue and circumstances. The BIG advantage is the system is designed to pick up repetitive problems allowing the factory to track trends and act on them! I've used this CSIR reporting system many times and it is the absolute best way to report issues and get action on them! In Canada here where I operate we're pretty lucky to have the Rotax Distributor Rotech, these guys are responsible for all "Certified" Rotax engines in North, Central and South America, most of which are run in high utilization flight schools meaning they see many problems and find solutions to them in most cases years before the non-certified fleet does! They also have a Hugh store of Used serviceable parts including crank cases, gear boxes, cylinder heads etc., for those looking for saving some money, as well they have the best Rotax factory approved engine overhaul shop in the industry. Their web site is www.Rotech.ca , I use these guys all the time to solve weird problems and they always seem to have the answers, many which I've reflected in this writing! Hope this info helps.......

Perhaps it's a simple as propeller balance and the associated vibration. My engine is 2004 so obviously within the suspect engine range however I've submitted an application for the MARAP program. Engines and other items on this program will be monitored to see if the lifespan applied by the manufacturer is accurate. My LAME chose to not rebalance my carburettors and propeller even though he brought the gear with him. He said it was a smooth and quiet as any Rotax so best not stuffed around with. If it's vibration related which it must be then I may have dodged that one.

Yes I mentioned this after the Korean airliner crash. On steep descents our truck arrester beds are filled with pea gravel/bauxite ore and it can be done at a much reduce cost. https://www.facebook.com/share/v/165ofjUU7k/ Many years ago, in the 70's we had an arrester bed at the apex of the hairpin bends on the Mount Cotton hill climb in Queensland. A car could be half buried in Macadamia nut shells without sustaining any damage however I was shouted down stating that it would create problems for rescue teams gaining access to the bogged plane.

I'm not bored but I'm only that busy because any job that I used to do in a day now takes a week.

FlyingVizsla wrote, I read - Kitplanes, EAA's Sport Pilot, RAAus Sport Pilot, Airnews (Aust Women Pilots Assoc) - in Print. Read a number of other publications in digital - Kitplanes, EAA's Sport Pilot & EAA webinars. Like their Engine & Kit Buyer's guides too. I have the last two SP magazines sitting in their plastic cover because I have too many unfinished projects. I've started building the airstrip but haven't got back to it because the grader (Ripper) I bought has no brakes so I picked up some parts for that earlier this week in Perth. I have a half finished gold cone (wet processing plant) waiting for bits and pieces to turn up. I have Mrs M's carport half built and I just brought home an industrial sewing machine yesterday to sew the shade cloth. I just picked up an oil transfer pipe and two windows for out motorhome that I need to get out there and fit. I just ordered a new park brake cable for the iLoad van I was driving in Perth when the park brake started to stick on. I have the plane sitting at Northam Airport waiting for registration so I can get back to flying and to top it off Mrs M has organized a trip to China right in the middle of my annual prospecting trip north. Right now I came in after snapping the two sewing machine needles that came with the machine and I've only done about 20m of sewing. The new needles are the wrong size so that project can go on the back burner for a bit. Mrs M is away in hospital so I might just sit back with a glossy magazine for a bit 😊

I think it's time I found that magazine I picked up from the post office a few days back. Where do you guys find the time...?

Aircraft traffic over a 48hr period. 13 March 2025 The FAA issued a revised helicopter route chart for the Washington DC area, specifically removing the helicopter routes 4 and 6 in the area of DCA and revising route 7 to the west of the airport. You can compare the old chart above with the revised chart below. For the full notice, including text descriptions of the route changes from the FAA. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.faa.gov/air_traffic/flight_info/aeronav/safety_alerts/media/VIS_25-02_CN_DCA_Helicopter_Route_Chart_Revisions.pdf

Aren't they in different states?

Probably a good choice, better than hitting the hard ground.

I love the undercarriage deign.

It depends on what you want to read. If you want articles of interest to aviators then perhaps you'd get the most interesting written by aviators and where are you going to find those?

Everybody is invited to put forward stories that they feel may be of interest to others. It's ok to sit back and have a grumble about the magazines content but how many aviators put pen to paper for the rest of us to read? If you have a story that is worthy of publication get it out there and then the rest of us might enjoy flicking through the SP magazine.

The bottom option looks the simplest. If you have two valves left and two valves right it could be quite confusing. A single L to R valve would be much easier to select and you are less likely to lose track of what's full and what's empty.
