poteroo Posted January 17, 2015 Share Posted January 17, 2015 We had an RV9 landing accident at Kyneton today. The nose wheel collapsed and the plane ended up on its back, but the pilot escaped with a few cuts and bruises. Take it that it was an RV9A? Was it on a good smooth surface strip, or a rough one? Does the aircraft have a history of 'off airport/paddock' operations? Curious because so far in Australia we seem to have less nosewheel incidents than the Yanks. happy days, Link to comment Share on other sites More sharing options...
pmccarthy Posted January 17, 2015 Author Share Posted January 17, 2015 Yes an RV9a on a good grass strip. A low hours aircraft. Link to comment Share on other sites More sharing options...
kaz3g Posted January 17, 2015 Share Posted January 17, 2015 Sorry about the aircraft because it was a really nice example...but very glad the pilot escaped without serious injury. Kaz 1 Link to comment Share on other sites More sharing options...
Ultralights Posted January 17, 2015 Share Posted January 17, 2015 did they get out easy? i love the RV series of aircraft, but the flip over and exit situation is probably the only negative i can think of with the RV's 1 Link to comment Share on other sites More sharing options...

That would be my only concern as I haven't tried them, the seat belt cutter part of them looks very good especially if you found yourself in water but as for the glass breaker on aircraft canopies I don't know Link to comment Share on other sites More sharing options...
SDQDI Posted January 18, 2015 Share Posted January 18, 2015 They work perfectly on the side and rear windows of cars, they DON'T work on laminated windscreens and they won't do anything to plexi/poly/plastic screens. Having said that they are an awesome little tool and I think a good thing to have but just keep in mind their limitations. They might not be the most helpful tool in the plane but have one on your car key ring for sure:thumb up: Link to comment Share on other sites More sharing options...

poteroo Posted January 18, 2015 Share Posted January 18, 2015 Yes an RV9a on a good grass strip. A low hours aircraft. Will be interested to hear of the pilots' technique when everything settles down and the shock passes. The 9A has huge flaps, a very low full flap stall speed around 42-44 kts - which necessitates considerable holdoff even from a 55-60kt approach. On many softer grass strips I've found that adding a touch of power at mainwheels on is useful in being able to hold the nosewheel off for quite some time. Avoiding brake use on grass seems to be a good precaution in the 9A. Anyway, pleased to hear they exited ok. The possibility of being trapped inside and upside down isn't one that anyone looks forward to! happy days, Link to comment Share on other sites More sharing options...
David Isaac Posted January 18, 2015 Share Posted January 18, 2015 It was VH. Exit was assisted by one of our members breaking canopy with a fire extinguisher. Therein lies the problem ... a major problem IMHO. Upside down in a paddock in the middle of nowhere ... very bad. Upside down anywhere and fire ... very very bad. I don't like low wings with lifting canopies for that single hazard. 2 Link to comment Share on other sites More sharing options...
Phil Perry Posted January 18, 2015 Share Posted January 18, 2015 Pack a can opener. Good idea mate,. . . . . but I've got say that every time I rolled me 'ute over into a ditch I could NEVER find that bloody can opener ! Link to comment Share on other sites More sharing options...

Would a sliding canopy with five or six hundred kilos of plane, crew and fuel sitting on it be anymore fun than a lifting one really? 1 Link to comment Share on other sites More sharing options...
facthunter Posted January 18, 2015 Share Posted January 18, 2015 Probably NOT.. Its always been a consideration, like roll bars in convertibles ( soft tops) Car passenger cell strength is a major advance in later cars. Most U/Ls have weak nosewheels. Rather easy to break them off. Tailwheel is better there, as mainwheels are further forward. 1 Link to comment Share on other sites More sharing options...

Rather easy to break them off. Tailwheel is better there, as mainwheels are further forward. I agree Nev, but we're unlikely to revert to t/w in the future, so have to work with the n/w versions. Fundamentally, we need to use aerodynamic braking instead of tramping on the anchors and placing load on the nosewheel. Brakes should be the control of last resort. Elevator command will be aided by having better load distribution, even in LSA. Really comes back to instructors setting the standards during basic training, and insisting on this technique during reviews and future recurrent training. happy days, 2 Link to comment Share on other sites More sharing options...
facthunter Posted January 19, 2015 Share Posted January 19, 2015 It only takes a rabbit hole. Keep the weight off the Nosewheel (whenever possible in a practical sense) on the ground by back stick. Makes some aircraft more pleasant directionally anyhow. Nev Link to comment Share on other sites More sharing options...
Phil Perry Posted January 20, 2015 Share Posted January 20, 2015 I had some interesting conversations with a Gent who came to the UK to assist on the build og the first A22 Foxbat imported into the country. He and his associate came over from Kiev and stayed with us for ten days whilst the first kit was assembled. They were a mine of useful information on light aircraft designs, both having worked for some years at the Antonov design Bureau. ( only one spoke English though ) One of their stories centred on the heated arguments they used to have with regard to the angle of mounting between the longitudinal axis of whatever airframe and nosewheel support strut assemblies,. . . even a very small difference in forward rake of the strut making a large difference to the stress calculations with regard to rearward shear forces applied to the structure, particularly with non - hydraulic / pneumatic oleo fixed installations in an average landing situation. ( Not actually exponential variations, but surprisingly large nonetheless ) Some of the calculations they showed us were quite interesting. It ( like everything else I guess ) always resulted in some kind of trade-off one way or another BUT . . . . . as Nev mentioned, . . .just one unexpected rabbit hole can often screw up all of the sums ! ! And as Poteroo pointed out, . . .if trainee pilots are not fully conversant with the systems at the end of training, . . you then get discussions about lifting and sliding windows. . . . . ! Stay upright. . . . Phil Link to comment Share on other sites More sharing options...

David Isaac Posted January 22, 2015 Share Posted January 22, 2015 It worked on this test: That demonstration is BS. The plexiglass wasn't installed in a frame that braced the edge. At least demonstrate a plexiglass in frame to at least NOT misrepresent a demonstration. 2 Link to comment Share on other sites More sharing options...
turboplanner Posted January 22, 2015 Share Posted January 22, 2015 Also a long way from reality. Have someone tip your aircraft upside down on concrete so you're hanging in the shoulder straps, have someone throw a pan full of dust in your eyes, give yourself a bang on the head with a wooden hammer, then first FIND the escape hammer and see how you go working upside down when the canopy, which is now a structural member cracks like it did in the video. 5 Link to comment Share on other sites More sharing options...
