What’s this about notches in the needle. My Jab engine book mentions them, but they don’t have a notched needle nowadays. 

Why fit EGT to a Jab or a Rita’s. Neither have mixture control as standard.

Well you can search on YouTube. Someone will know how to adjust them.

Why shouldn't a significant section of the Flying community Administration that has regarded itself as the New GA Be similar to any Airline in principle and be active re accident and incident concerns, treatment and involvement?. Nev

OK, all in favour of being in the New GA, and upping the RAA subscription to $5,000.00 to build ATSB2?

That's for the above . ALL Airlines get documents and advice of inspections required or Parts replaced or retraining . Any Airline worthy of the name has a operational flight safety department. IF THEY do the appropriate thing , The Authority leaves them alone which the Companies prefer, naturally so often they impose a greater penalty than the Authority would have.  Nev

You realise we are talking about RA aircraft and the recent decision of Recreational Aviation Australia?

Before Sept 11

The ground staff (& occasionally crew) would keep the public on the terminal side of the fence and shepherd the passengers to/from the aircraft.

Unfamiliar faces around hangers, picnicking on the runway threshold, etc would be challenged by maintenance/ local pilots/engineers and the like.

After Sept 11

What has changed ?

Nothing other than having to go through the charade and expense of acquiring an ASIC and airfield owners having to put up extra fencing (may not go very far) with a security (ha!) gate- its a complete shame.

You're only telling, us, the converted Skippy.

What is specified inRAAus rules and regs, I thought they were responsible for safety and I fail to see how they can be responsible without investigating accidents.

Well first priority is their duty of car to eliminate reasonably forseeable risks.

Then comes investigating accidents becaise that an inform future rules and actions.

Surely that’s like saying Qantas has to do it’s own fatal (hopefully not) accidents because they have an SMS that requires them to analyse all safety reports.

I don't think that is it, your typical lycon is probably more rich at low power setting unless the pilot leans on the ground.

Maybe not but I'm not thinking of flight, just the last few minutes or just the shut down itself. I've pulled pistons out that were bone dry and others soaked in fuel/oil.

I have seen about 20 lycoming/ Continental pistons following cylinder removal due low compression. Non have had stuck rings if I remember correctly. What is the difference with these engines designed to and all would have been run on avgas.  

Lycoming/Continental are shut down by pulling the mixture to zero, so relatively dry cylinder shut down.

RA 4 and 2 stroke usually have on/off switches so oil up on taxy to parking area, full rich shut down?

OME : It's significant that the sticking wasnt random. they're stuck within a few degrees of precisely the centre of the minor thrust side.

A lot of things are happening inside the combustion chamber which is alternatively heating to around 2000 deg C, then cooling, piston going up then reversing and coming down piston faces pushing against ro bore on opposite sides alernately, rings banging on each adjacent land every rotation, ring to barrel pressure in different directions, gugeon distorting the piston, and mixture entering at all sorts of different richness in each cylinder and each owners engine and each make of engine. and each hour/hundred hours of service.

The result of this is that your engine on your application with your fuel richness, your timing, your exhaust, your rpm behaviour cool down behaviour wil produce a different visual/mechanical result.

Some people glaze bores, some burn holes in pistons, some have sticking rings, multiplied by different makes, models, sizes,layouts.

In my racing engines, I get to see the results often and at early hours and now and again through the open barrel hole in the side of the cylinder. You get to expect the characteristics of normal cylinder temps, and a sharp rise due to the cylinder being given a very heavy load perhaps due to a spark plug lead coming of another cylinder.

So if this pattern of stuck rings you're seeing is common across the engines you're pulling down, pick one of the above; it will relate to some common thing being done to those engines.

I think you're right turbo. But I would add that if the government is interested enough to place lots of regulation on RAA, surely they should do this with open eyes and understand if the regulations do good or not. In otherwords, the government can't have its cake and eat it too. And like I said earlier, I'm pretty sure ATSB treat VH- experimental the same as a type certified aircraft operation. This is only because there is a part 61 licence holder at the helm. 

 

It's all just splitting hairs to me. 

You're looking at it back to front; the government gave RAA and exemption to fly and gave them the freedom to set their own rules (Self Administering Organisation.

Experimental flies under GA rules.

If you start to pick and choose parts of RA, parts of GA, parts of US regulations or European regulations or NZ regulations they all started from different beginnings, different people and different pilots changed them along the way and here we are nearly a hundred years later each with their own rules. RA was never meant to fly interstate let alone nationally, so better to pick one and live within its rules.

3 minutes ago, Flying_higher said:

The only reason ATSB are there for VH- registered aircraft is because they wrote the rules (TSI Act) around what their capacity (funding) is. I just can't see why the life of one Australian is more important than another depending upon whether you have numbers or letters on the aircraft. Surely this is about improving aviation safety?

RA flyers wanted to build their own, use specifications below the safety minimums of GA aircraft, do their own maintenance, do their own training and qualifying to a lower standard and make up safety ground by setting a very low stall speed. There might be more, but enough to demonstrate what RA was established for, so you can't have your cake and eat it too. RAA has to decide what level it's going to place on a life.

RAA through it's predecsssor took RA aircraft from the limitations of paddocks away from airfields and below 300' to flying out of regional airports. The current safety system is based on that scenario. I understand the dot you are drawing, but the present RAA system doen't have a bad bad name for interfering with GA.

Turboplanner -

 

I have no recollection of "terrorist activities where people simply walked on to an airfield started up light aircraft and went on their mission to crash the aircraft on a city targe" . If this did happen, there are better ways to combater such behaviour  eg  try having an ignition key in each aircraft and or locking the cockpit - we do it for car why not small aircraft (my last & my current both have this simple logical feature)

It did happen; I believe ignition keys were tried; the result was the cabin padlock everyone uses today; you do have one fitted?

As I see it, the majority of pilots in the small aircraft fraternity, have consistently voiced our opposition to the imposition of ASIC on us, where it relates to minor airports around the country.  These pilots have not been heard no have the airport operators who have had considerable extra expense for no discernible benefit.

They certainly have voiced their opposition to each other. There are several threads on tis forum and others, and the threads eventually peter out so instead of 200 people contacting the government just a few have, so it's seen as a non event.

I've given the pathway to the OP, so I guess we will see if he has a meeting with his Member, and starts the ball rolling. I did that on another subject about three years ago and the issue was fixed in a fortnight. Nothing to stop you doing the same.

From what RAA said at their AGM, they will continue to help Police where they can. I don't think their aim is to be obstructionist but just make sure they aren't trying to be the ATSB. They also said they'll always analyse what they can with the info they can through their SMS and that CASA were ok with this.

 

I actually think its odd that the Government (via CASA) issue all these regulations but because the ATSB won't do their job, they (CASA/Govt) have no idea whether the risks they say they're supposedly controlling with the regs work, because the investigation part of the cycle is missing. Does this mean we should ignore the regs too? From my perspective you either do the whole cycle or you don't do any of it!

Be careful going down that path.

ATSB are there for VH registered aircraft; they will if the issue is important, step in and investigate an RA aircraft.

RA aircraft fly because RAA is a self administering organisation; it's up to RAA to manage the organisations risks.

Where it gets a bit confusing is that the minute you enter a runway at your local airfield,  CASA, Airservices and ATSB rules also kick in, but I certainly wouldn't be saying ATSB won't do their job.

Actually my comment was not in relation to that. The Coroner, aided by the police investigation on the Coroner's behalf, welcomes any reliable information when conducting an Inquest. The Coroner is seeking factual information and if it comes from experienced sources, all the better.

 

My comment harkens way back to the fundamentals of Management Systems which can be identified in this simple diagram:

An organisation creates a plan or procedure aimed at attaining a result. Then it does (implements) that plan or procedure. After implementation the results are monitored (checked) to see if they match the expectations, and decisions made to keep the status quo, or to modify the plan or procedure and go around the cycle again, again and again until there no more reasonable improvement can be made,or the goal of the plan is reached . Does that sound like Harvard School of Business mumbo-jumbo? Hardley. You did exactly that when you made your cuppa this morning.

 

Failure to be involved in the investigation of incidents breaks the cycle and precludes any further improvement on the one hand, and on the other opens the door to declining standards.

Yes, I agree with your cycle.

I agree that anyone or an organization can provide information to Police, Coroner and ATSB.

And Police have been calling in RAA for assistance at sites. (Not sure if this will continue under the new RAA intent)

However the grids I was referring to were a person or organization going into a crash scene and doing their own thing, so just the legal grids or boundaries.

Rough running engine between 4800/5200 , new throttle cables , Carbys done, balance good , runs fine either side of those revs, 

Needles, check manufacturer needle specification (needles come in many sizes and tapers), check manufacturer clip specification.

Bring it back to manufacturer specification.

Needles control the mixture from around 3/4 throttle for the transition to cruise/full throttle where the main jets do the controlling.

(Rotax may have the rpm for transition just to make sure this problem isn't on the main jets)

As others have said no need to do anything near the engine when you test for the rough spot.

Start engine on the manufacturer's needle specification and clip specification; if the engine is stumbling because it's over-rich, move the circlip one groove away from the point of the needle (which pushes it further into the jet). If still rough go another notch if there is one until you run out of notches. If that hasn't fixed the rough spot, go back to the manufacturer's groove +1 groove towards the sharp end like you did before, which is now leaning the 1/2 to 3/4 section of rpm. If that doesn't do it return to the manudacturer's grroves.  If it ran clean immediately before you fitted the new throttle cables, with a vernier gauge tail and the carbies off, check the slides are equal depth at idle, half throttle, 3/4 throttle (where the rough spot is) and if you can feel them hit WOT together (or if not, measure them just before the touch point). Sometimes with new cables one has a kink or is stiff and one slide pulls ahead or lags, and one could be getting on the main jet while the other is still using the slide cut.

Its implementation was a kneejerk over reaction to Sept 11.

It was in response to some terrorist activities where people simply walked on to an airfield started up light aircraft and went on their mission to crash the aircraft on a city target; from memory the attacks that did occur were erratic and didn't do much damage. There were also the pilots in the 9/11 attacks who trained at US airfields.

After Victorian elections I used to have dinner with a Minister; when my side won I shouted, when his side won he shouted. In 2002, 14 months after 9/11 which had already faded from most people's minds including mine, I asked him what he was going to do. He said the new government would focus on security and water. I asked him why Security? and he said We've got 12 terrorists convicted and locked up in prison from the last three years, but the scary thing is we don't know how many more are out there.

A lot of the key people like Osama Bin Laden who had the skills to organise attacks around the world and organise the conditioning of young people have been taken out, but we the public still don't get to know how many are locked up and how many are out there we don't know about.

The recommendation I made four days ago sets in motion an action system in the Member's office, which usualluy results in a visit to the Minister or Shadow Minister and if there's smoke can lead to a question in question time or to a Senate Committee Hearing if there is any substance to the claim.

In 2015 the Government had decided to drop bulk billing and make us pay around $80 to $120 per visit. I happened to be in the Parliament, and dropped into the Senate Committee Hearing when the people's complaints played out. The people weren't getting anywhere until the local GP from Tamworth made his submission. He pointed out that he had to rent a large Clinic, pay staff, power, cleaning, reception, materials etc and was not making a lot of money after that. He said if bulk billing was dropped a lot of his patients wouldn't attend and would becomes more seriously ill, and he would have to close the clinic and could make more money working out of the local hospital. There were some murmurs and talk among the Senators as both major parties realised that meant they would be paying for all the doctors, not the States, and the Committee was brought to a close. Bulk billing wasn't dropped.

By someone asking about ASIC it triggers someone to check the current status, and if in addition to the personal visit a three or four page submission, which covers the pros and cons is handed over it could well be that a committee is set up to take evidence.

Absolutely foolish. 

I agree; there are definitely grids of government responsibility to stay away from, e.g. Police, Coroner, ATSB limitations.

However the benefits of examining the simpler cases are self benefiting. 

Ultimately Self Administering bodies need to minimise their casualties regardless of the sport, or they risk running out of PL insurance capacity, or are shut down. Setting up compliance and enforcement and a natiral justice protocol are relatively simple.
