Solo student pilot in Cessna crash at Parafield walks away. 05/01/26

The degree Of damage a Backfire can cause is dependant on the Amount of charge that Gets Ignited. with a supercharger that can Include IT'S volume, What's in a very Large Carburettor and the Manifold and a cylinder or two. I'm convinced that these backfires on start, resulted in a lot of Failed Cylinders at the shrink Band on Big radials as well as other engine issues.. The forces are enormous. LPG gas Backfires on cars can shorten a  con rod or Split A VEE Block. Fords dedicated gas six RUNS much heavier rods THAN STANDARD. Nev

We will be to scared to fly if we read much more of this.

Are you saying crossing the plug wires to clear the carby jets is not a good idea? 😁

[facthunter]

What BS. you guys.  Easy to get a sandstorm in some parts of Australia . It's getting so it's impossible to have a good discussion Here.  Well done .Just a waste of time.. other people visit THIS  site it's becoming a Joke. That's the SILLIEST thing you've said so far Mb. IF you want to be silly try the  Off Topic section and Leave this one for the non Idiots You are certainly doing your Best to just make My serious input a JOKE. Do you think that is FAIR?  Nev

The only input you want to hear is your own.  It's ok for you to joke when you feel like it.

Can you please post a list of requirements for a post to be satisfactory for you.

You are bullying moneybox .

There is no need to carry on at him the way you have on this thread.

And look at the replies you posted to me yesterday about that gyro.

I think you need to man up and apologise for your behaviour.

you are the only one that said we use motorbike filters.  k&n supplie filters for all rotax aero engines.

 

or K&N air filters suitable for Rotax engines, consider the following options:

• K&N Universal Air Filters: Available in round, tapered, and oval designs, these filters fit various applications, including Rotax engines.

i haven't made judgement of you. just pointed out you can be guilty of exactly what you accuse us of.

but i do agree things can come across as agressive when that is not the intention, keyboards don't convey emotion very well.

i am guilty of pulling your chain, only because you bite so well. i will try and stop doing it.

but everything you said about that gyro was wrong. (sorry i slipped back into my old ways😁)

Unfortunately, sometimes on here we may be dealing with the same person writing under several aliases. I'm not talking about you FH.

I don't mind because some of the material is good.

However some people don't know when to stop and have no idea of engineering or mechanics, so a lot of important safety information just gets blown down the gutter and lessons are lost.

I only have one alias which is my real name.

How does it help safety when you come on here talking crap about 2 mt backfires and saying we are using filters not fit for purpose when they are designed for Rotax and have a part number for each model.

 Aren't you the same bloke who defended finemores dragging a trailer for 65km with all the tyres blown .

Look at yourself before you make up stories about others.

If you are belching out 2mt flames a change of diet may be in order

[BurnieM]

I think it is misleading to say that an air filter originally designed for use on motorcycles should not be used on planes.

 

All the different brands of oil filters I have cut open are low quality, mass produced products. This is generally acceptable on all engines as they do adequate filtering at this quality level. The retail price these oil filters are sold at varies enormously. Branding appears to mean very little.

 

I have replaced 40-50 sets of sparkplugs on motorcycles and the occasional car. I eventually settled on NGK as they (in my experience) never failed and lasted well beyond their stated design life. I have only had 2 sparkplugs fail completely; one was a Bosch 20 years ago and the second was a Bosch 2 years ago. While Bosch may produce reasonable quality in other components I have no faith in any of their spark plugs.

 

Many (most?) decisions on replaceable engine components are not made by engineers, they are made by accountants and lawyers.

The above has a 2 3/4" flange.

FYI: The similar  filter, with a 2 1/2" flange,  K&N part # SN-2540, used by many Rotax 912's,  may have been discontinued.😈

Some filters may alter the Mixture if they are not Large enough or get clogged up, That's important with an aircraft. Nev

Just to clarify what I witnessed.

A backfire lit one of the air filters.

Four side by side filters caught fire and the fuel/oil mixture fed a fire that was 2 metres high.

A person was trapped by a faulty harness, her head about half a metre in front of the tyre.

A fire truck was there in seconds and one team started cutting the harness and the other put out the fire.

It took some minutes to fire-out and person-out.

 

Since we always have a problem unless an example is given exactly in and aircraft, think of this.

 

If the same filter, even the same part number filter is located in the engine compartment of  a recreational aircraft, fuel and materials will be the same so the fire volume will be the same, but this time that two metres of flame is going to have to find a way of escaping, and if you are taxying or flying, that's likely to be in the pilot's direction.

 

I know the origins of these engines, where the rider could depart immediately, so fire would not be an issue, so I would be making a slight change, but it's up to the reader to do whatever he/she likes.

Any filter can block up. That's called maintenance. When you change or wash them at required intervals.

[facthunter]

Depends on whether they are BIG  enough. EVERY Motorcycle I've fitted a filter to has to Be retuned and I fit Bigger ones than those. This is well Known. It doesn't take MUCH TO

 alter THE MIXTURE. Nev

My 618 had the intake silencer box removed. They had to rejet the carbs to allow for the change in restriction. 

Interesting thing with 618 is the main jets are a different size in each carb.
