Scratch a Cirrus ?
Dear Dad,
How I love the smell of a new plastic aeroplane in the afternoon !
I was making a flying(!) visit through YMMB on Tuesday afternoon when I spotted a new Cirrus start-up at the fuel station, strobes flashing away from engine start, but then maybe that is a kind of holding point.
The aircraft then taxied away down-wind with the huge left door held wide open. The gusting west wind was of 10-17 knots so the door-sail no doubt helped conserve power!
As the Cirrus taxied out on the inbound taxi way the door was of great assistance for other pilots taxying in to see.
I always knew that my instructor gave me a bum steer on that left and right thing!
That door must have given a lot of push to the a/c, It sailed right past both run-up bays and straight out for departure off runway 31.
These Cirrus plastic fantastics must be real good that you don't need to do a run-up check. Probably a sales feature.
I like the finish on the Cirrus but I suppose someone will scratch one, unfortunately probably sooner than later.
On another subject, while Victoria has water restrictions I am told that there are no such restrictions in Tasmania. I suppose the Wallys of the world gather down there.
If you can tell me otherwise I will be ZEL-defied.
Safe flying
Your loving son.
CJ.
Dad,
P.S.
When I write next I must tellyou about the reasons for the rising cost of aeroplane insurance and the need for tougher BFRs'

What a load of absolute rubbish, the industry doesn't need people like you, crawl back into your hole. I've noticed other posts like this by yourself, something to do with GFS in a thread a little while back. Go away.

Initially I thought....this is gonna be a real sensible letter from a young aspiring aviator to the Dad on how he/she's gonna become a great pilot to enjoy the pleasure of operating a Cirrus....
But then,,,,Zippidi Doo Daa
May be we could post this to the Roving Enterprise.
WHAT THAAAAAAAAAAAAAAAAA?!?!

I second that SmoothCriminal. New as I may be to this forum, this would have to be the most un-informative post I've seen to date. If somebody can identify what C.J. is trying to express here, please let us all know.

I fly Ultralights even! (yes, a plastic fantastic) and even i do run ups on the move! but there isn't to much to check during a runup with a 2 stroke powerplant!
the joy of plastic! 110Kts on 40 HP. oh, and stressed to +12G.

The sounds of silence if you don't. 
Or are those Rotaxes oil injected?

Well there you go.
The real wonder of PPRune is that it allows the posters to self sort themselves into the realuns, the going to be, wannabes and the neverwillbes.
CJs letter to Dad was tres droll and a joy to read.
The points, supposing that you were you able to see them (see above categories) were exactly spot on.
I think my friend Jarse would agree, that no runup and runups on the run, share about the same level of risk, though for quite different reasons.
And we don't need to go on about the use of strobes do we, what's the betting the transponder was on too.
If I recall the door on one of them is at least as big as the tailplane and would be able to have much the same magnitude of effect with the the not unimportant exception being that the result of the effect is out of your control.
Which brings us back to the beginning, was this aircraft under the full control of the driver.
He may have thought so, I like CJ suspect otherwise.
Anyone?

Hugh Jarse,
Re the oil-inhected 2-strokes:-
The Rotax 582 99 UL CD model (the "blue-top" engines) can have oil injection as an option. Earlier 582s were pre-mix only and retro-fit is not possible. Oil-pump is driven by a cross-shaft and linked to the throttle cables by a cable-mixer. Users tell me it reduces oil injected at low revs to a 1 in 100 ratio but reverts to a 1 to 50 ratio at higher revs. My CFI reports the reduction in oil usage is noticable and he gets almost no oil-residues deposited on the prop-blades (pusher installation). He has owned a lot of 582s and likes his injected one a lot.
The bomb-proof Rotax 503 can also have oil injection as an option although I've never seen one. Oil-pump is fitted to front of recoil-starter housing, driven by a shaft extended off the alternator drive (which is direct off the crankshaft anyway).
At the rebuild my 582 will get oil injection retrofitted. Nice to be able to put fuel in fuel tank and oil in oil-tank instead of doing the "pre-mix rhumba" at the servo!
As for run-ups on the run as it were, yes, quite possible although prefer to do mine whilst parked with the brakes on. With a dual CDI ignition system on the 582 they don't take long and at 3000 RPM the brakes hold the a/c perfectly for the run-ups.
Trick for good life in the Rotax 2-strokes seems to be use the right kind of oil and in the right ratio. Regular compression tests and cyclone bearing end-float tests also help check for adverse wear or stuck rings.

Yes there is. That you have put oil in your petrol The sounds of silence if you don't.
Or are those Rotaxes oil injected?
I have a Rotax 447. and i usually pre-mix my fuel-oil Before i start the engine!
Unfortunatly Rotax 2 strokes are very pickie when it comes to oil, Myslef and others have never had any probs with Castrol synthetic 2 stroke oils.

My Bonanza, as part of a speed kit, had the rotating beacon removed and only has strobes, which go on before engine start the way a beacon should....I know nothing of Cirrus aircraft but perhaps they are similar.
Is a FULL engine run up check required before every flight on a given day or just the first? Perhaps he just made a quick 'dead mag' check as he taxied for the second sector of the day...as he was taxiing from the bowser seems reasonable.
One way taxiways? Don't know YMMB so looked up in Jepps...no mention of 'inbound' or 'outbound taxiways'...presumably he was talking to Grnd or Twr so there is the destinct probability that he was following instructions.
Taxiing with the door open in a stiff breeze certainly sounds dumb...obviously the individual concerned is a complete fool and should not be allowed anywhere near an aircraft...you were right to report this serious matter to you Dad.

I don't know anything about the Cirrus aircraft but when I flew aircraft that wern't airconditioned I must admit in the warmer months I was certainly guilty of taxing with the door open (at least on those types that I could ).
And I can assure you I was not on my lonesome in doing so.
Tres uncomfortable inside a hot aircraft with no airflow is what I remember.

Interesting
My first job out of school was in a Suzuki dealership fixing bikes. Back then, Suzuki did not produce 4 stroke motorcycles.
The oil injection they used was really weird (IMHO) in the fact that the pump ran one line to each cylinder that injected just downstream of the carburettor, and lines to all the main bearings except the left. The left main ran in the transmission oil.
All the other Jap manufacturers simply injected downstream of the carby, or near the rotary valve and this also took care of the mains. Much simpler IMHO. But we never replaced many main bearings though.
Failures due to oil starvation were extremely rare unless you ran the oil tank dry
Plus you don't have to do the mental gymnastics when doing up a batch of pre-mix

Chuckles.
I remember the debate some time ago when it was mandated that strobes could be used in lieu of the rotting beacon that used to be a requirement and ground movement at night.
It got pretty willing but was mostly driven, as usual by cost.
I am still a firm believer on not turning on strobes until you are about to enter the runway, certainly at night, hence the need IMHO for a rotting beacon as well. Sitting at the holding amongst a sea of flashing strobes when you are about to launch into a black hole, isn't my idea of being well prepared. But then I'm an old duffer now.

Well done CJ - but your Satire (not sarcasm) appears to be a bit too advanced in format for most of the dummies who have posted comments here. The translation for those people is that the cirrus belongs to a senior public servant from Canberra who occasionly allows his little right hand man to fly down south in it to keep a tight rein on the minions in the ml office. Hope I've hit the nail on the head CJ.
