Lancair Legacy




New Dynon EFIS gizmo soon available to kit builders.

RV-10 panel all glassed out with current tech. The lack of any personal touches is because the builder didn't build this for himself, but posted it for sale "ready for paint job of buyer's choice" - building for profit violates the intent of the experimental aircraft laws and has furrowed some legislative brows. Not good.




DynAero MCR 01, carbon fibre wonder of the ultralight world. Its speed envelope is between 34 and 160 knots.

Something is wrong with one of the engines, too, as one nozzle is tight while the other is open. And only one is spouting flames during the impact, but that might be coincidence.

I agree. If you look at the video it seems like he's doing the low/slow/high alpha pass, which is a staple of any F-18 performance. When he hits full burners to accelerate out of it, the right engine isn't responding and that much asymmetrical thrust at near stalling speed means instant membership in the Martin Baker Ejection Tie Club. The shots of the sequence are incredible.

Raytheon Permier Jet crash at Oshkosh.

Eyewitess says:

quote:

It was Jack Roush's Premier. I saw most of it until it disappeared behind some planes. He appeared to be at high alpha, way behind the power curve, and then went into what appeared to be a 45-60 degree bank. Wing hit first, jet spun around 180 degrees or so, and the rear section of the fuselage broke off. No fire. I watched the pilot walk out (very bloody) and heard that the sole passenger was ok.

Pics of said bloody pilot in the thread. drat! Probably not as bad as it looks, you do bleed a lot from face/nose cuts.

I'm dreaming about owning an ultralight as well. No way it's going to be without a BRS. There's been two fatal ultralight crashes in Norway this summer, don't think either one had a chute. But both cases was low altitude, stall or engine failure, that thing does need quite a few feet to develop fully.

Although in rare cases it can be a liability as well.

Other than sperg value, what's the real difference between the two?

The difference is basically just the name. Military bureaucracy demands its units in service to follow the official military naming convention. But fundamentally the DC-3 was a passenger plane and the C-47 a cargo plane, so militarizing it means ripping out the interior, widening the door and painting it green. But both of them were used for a zillion different things with different modifications.

They also do a full rebuild every 300 flight hours vs USAF's 10k+ hours.

It's a different doctrine, not just different maintenance schedules. Russians have conscripts doing aircraft maintenance, so they don't do troubleshooting or repairs on the field. The engines run virtually without maintenance for (say) 300 hours, then they simply pull the engines and send them into a central site.

This classic example of commernist centralization probably works best in a world where cruise missiles / stealth bombers don't exist and your central maintenance site won't get blown up on day 1 of the war.

I know it's a whole different mindset, but it's hard to say their engines are better because they're more willing to eat small pebbles.

Yeah and I don't think the pebble statement is very true either. The Soviet have often designed their aircraft with rough runways in mind, either high mounted intakes or FOD doors.

Saw this video on another forum a while back and just came across it again, it might've been posted here as well. Inadvertent IMC, or getting into clouds when you shouldn't, is a big killer in general aviation.

Ok, I'm a big fan of experimental aviation a.k.a. kitplanes. Done right it is one of the finest home engineering hobbies and with easy access to the wealth of knowledge from fellow builders it can truly turn out a wonderful flying machine that puts comparable certified machines to shame.

But this is the complete opposite. This is the most incredible NTSB report on a GA accident I have ever read. Put something soft on your desk, your jaw will be doing multiple drops.

I could understand someone duct taping a piece of wood or styrofoam to the rudder when trying to size the fixed trim tab which most of these aircraft have. But only for sizing it, after the quantity is know it gets installed properly with rivets or aluminum and ideally it takes place during the Phase 1 testing.

This guy didn't bother with the Phase 1 testing, although he claimed to have done 40 hours in one week. Which should have launched many eyebrows up into the stratosphere given that a completely orthodox installation gets a 25 hour Phase 1 but easily takes a month to finish.

The list of errors is so long and amazing, it's frankly quite shocking that nobody in the community around him really sat him down for a talk. If afraid of personal confrontation someone should just have called the FAA.

Anyway, one has to admire the linguistic restraint of the NTSB guys writing that report.

The whole premise of the lightweight F-16 was that it would be stationed up and down the European front lines and intercept the Soviet bombers. The MiG-29 was designed with the same concept in mind, a point defense fighter. The scenario is long dead of course, now F-16s look like this:

Have been reading a few NTSB reports lately, this one is quite amazing.

Summary:

- Cessna 337 (the one with 2 engines, tractor/pusher) goes to high altitude to take pictures
- Oxygen system has erroneously been filled with compressed air, both occupants go hypoxic and pass out at 20.000 feet.
- Plane descends uncontrolled, overspeeds and breaks up.
- Passenger loving survives!

I've always liked the RV series and in an ideal world would love to build an RV10, but one thing that puts me off is I just wouldn't trust myself not to screw something up.

That's a good attitude to have. I think you need to approach it like someone doing a 15,000 piece puzzle - it's not the finished object that's attractive, but the meticulous process of building it right. If you want a big pretty picture of a Venetian bridge, buy a poster. If you want to fly right away, buy a factory plane. But the resources available for the builder, particularly in the US, provides such a vast amount of knowledge, experience and technology within easy reach. And of course the NTSB provides a lot of "don't do this" information. If you approach it as a hobby engineering project where you're willing to learn everything that remotely affects your situation, above and beyond what is actually required, you're on the right track. And also the patience and persistence of a Buddhist monk traveling to the shrine by glacier.

Obviously the massive carrot at the end of the 3-7 year project is a plane that will blow the doors off any rental/club machine, perfectly equipped to your desires.

I'm currently dreaming about a night VFR RV-7 with a Deltahawk diesel, autopilot, a bit of EFIS candy and oxygen system to take advantage of the high altitude capability of the engine. Might as well be dreaming about my own F-15 with Nerf missiles. :xd:

Hahaha I love stories about aircraft idiosyncrasies. I don't have any links or usable memory available, but have read some rather hairy stories about, for instance, Royal Navy pilots in the early jet age. Carrier ops in the 50s was pretty rudimentary stuff.

Here's a great video which I'm not sure has appeared in this thread. Yak-50, popular acro plane, suffers engine failure and lands in a field. All in glorious high-res, annotated, pilots perspective video.

quote:

Post major maintenance/life extension at EGMJ a YAK 50 loses oil pressure over the Lake District at 1250ft.
Engine runs until dry before seizing, gearbox u/s and windmilling prop at 3100ft followed by glide, wheels up (no flaps on the 50) into a rough field with an upslope at 500ft amsl.
First impact to full stop 47 metres, first belly impact approx 35 metres.
Aircraft did not go through wall, right aileron did contact with a fence post.
Wind reported at Carlisle less than 5kts - windmills visible not turning and shutdown. Ground soft.
When the engine seized it caused the reduction gearbox to disintegrate hence a windmillling prop and engine shut down with mags off and fuel cut. On inspection the cylinders completely solid, engine core since scrapped.

Beautiful, but I wonder how they're dealing with fatigue in the CF. From my classes, it's a bitch to detect fatigue damage before it reaches unsafe limits.

That made me wonder too. There is quite a lot of glass fiber aircraft around, is it very different from carbon fiber?

In other news, flying a U-2 is hard.
