Feeling discouraged

I collected my trike from Flylight today, but was rather disappointed that having fitted the throttle, Ben hadn't tested it, fired up. He said he couldn't without the prop...but I had deliberately left it behind the seat and he had overlooked it.

So Ben agreed to try the engine with me but we couldn't get it to start. Ben kept trying until it drained the battery. He checked all the lines and all looked right - I had put it all back together after cleaning the carb, but couldn't convince him that I hadn't somehow managed to block the idle jet while cleaning it.


Fuel was definitely being drawn up, but the lack of a smell of fuel didn't seem right. So Ben has said that I should take it back to Paul Bailey, who has always been very good to me, but who may not feel as magnanimous a third time. Ben has emailed Paul and hopefully he will get back to me Monday.

This is really getting beyond a joke now. I am not blaming anyone....these things happen and are clearly all part of owner-operating a plane, but for a plane which is meant to start every time (so that you can turn off and be sure of starting it again in flight), I seem to spend a hell of a lot of time trying to start it and keep it running.

Car Trek Voyager

Latest addition to my trike transporter is this bit of metalwork (I made from scrap), which bolts to the one-time back seat member, making a support for tool locker hatches behind the front seats (discreetly extending the back of the van bed over some storage space) and incorporates a drinks bottle holder. More pics when the project is finished, but for now....

When I took this photo the metalwork looked like
a distorted Starship Enterprise - do you see it?


G-CFKK goes home to Flylight


Before heading off to see Neill at Sackville, today, to look at his engine, I dropped my trike off at Flylight to have its foot throttle fitted

It was good to see Cath, Bernie and Paul.

There was a lot of activity....the Harvard showing off, an autogyro refuelling, a Tiger Moth...and lots of flexwings on the grass.

I wished I was flying too :(


an EXTRAORDINARY engine failure

the offending nut - well mallered!

see description below

pitting in cylinder head

goughing in the top of the piston

I had the privilege of being present, today, at the post mortem of Neill Howarth's 912, 48hrs after he brought himself and his student safely down, after it shuddered violently and stopped on take-off.

Amazingly, it turned out that the nut which held a cowl over his air filter's heater had vibrated loose and was sucked through the carb, through the inlet manifold, through the inlet port and was trapped between the piston and the cylinder head, where it was hammered violently. We think the washer must have broken up on the filter cowl bolt, easing the nut so that it wound free...and that the bits of washer got caught in the carb (where we found them). Some debris went into the rear cylinder head too with less catastrophic consequences. The gouging and pitting in both the starboard cylinder heads, just near the valves, and on the pistons is very clear.

It is hoped that the cylinder heads can be cleaned up, the pistons replaced and stress testing done...and that these steps alone will put things right. It could have been a hell of a lot more expensive.

effing celebs in Spits etc

Is anyone as sick as I am of celebs and other TV types getting rides in Spits and Lancs, etc.....because it is part of some programme or other about the war?! Half of them don't even realise what they are being given.

Urrrrgggghhhhhh

Back to Ben

The carb went on fine...along with the electrical re-connections etc....but that frayed throttle cable was a bugger, so I rang Ben, thinking that maybe if it needed a new cable, I ought to bite the bullet and get a foot throttle fitted too...and as I'd be asking Ben to fit them, he'd set up my idle power setting properly for me too.

Ben was delighted to hear that I had been so daft as to remove the brass thingy on the end of the cable, saying, "This is all a bit beyond you really, isn't it" :) Apparently, he insists, I could have removed the throttle without undoing the brass thingy.

So, I am taking the trike to him tomorrow and picking it up again next Friday, at the start of half term.....solving a bunch of problems.
At the end of this crisis, as was the case at the end of the last lay-up, I shall be left with an aircraft which is better than before. It has been odd flying on a hand throttle alone...especially when landing. I think a foot throttle will give me far better control - it is a nice little design too.




p.s. Thinking it through, I can see now exactly how I should have taken the brass thingy out without undoing it. It is just the same as dismantling bicycle brakes. What a numpty! (I feel embarrassed)

Here's the plan

OK, here's the plan. Saturday, SM to do mechanics.
Sunday, go back up there to fly!

(providing I can shake off the last of this cold...and get everything back together satisfactorily)

Sunday looks great, with 3mph winds forecast.





For reference purposes, I have loaded pics of my carb assembly on to my GPS :)
and made up a sheet of them, just in case the battery dies ;)

-It sometimes seems like, no matter how many tools etc I take up with me, I will always have forgotten something...or failed to anticipate a need. But I am getting there.
