Creamie, your joking...right?
Unfortunately it appears you have not been present when someone has
Removed injectors for cleaning, as I can tell you, it is quite necessary,
Continental are 300hrs or periodically,
GAMI say 100-200 hrs for cleaning.
And please cut it out with the old " doing it for $$, or creating work bulls#€T,
I'm sick to death of it.
Next time I remove some injectors I promise, I will take some pictures and
Send to you.
Avgas...cleaning medium.. Not so much..
Kero...yes more so.
Firstly, schedule 5 is not used in isolation.
Schedule 5 is a list of things to look at, not how to maintain
Your aircraft.

Some choice quotes..
"However, some operators of privately operated aeroplanes favour CASA Schedule 5 over the manufacturer’s schedule, because it appears at first glance to be simpler (and cheaper) than the manufacturer’s schedule or an SOM. However, you should bear in mind that Schedule 5 is just a list of inspection items, a ‘shopping list’ of tasks to be completed either every 100 hours, or 12 months (whichever comes first), without any specific instructions on how any of the inspection items listed in the schedule should be carried out."
Remember also that under CAR 42V (1), because all maintenance is required to be carried out in accordance
with the applicable approved data, you must still consult the manufacturer’s maintenance manuals for the airframe, engine and propeller, as well as applicable literature such as service bulletins, for instructions on how to carry out inspections and corrective maintenance.
And this one,
"If you do not follow the manufacturer’s maintenance schedule, you should know why, and be able to explain your reasoning to an auditor or accident investigator."
Here is the schedule 5 section on ignition systems.
IGNITION SYSTEM
(1) Remove the spark plugs, clean and inspect them, check the spark plug electrode gap, test the spark plugs and renew them if required.
(2) Inspect the spark plug high tension leads and ceramics.
(3) Inspect the magneto housing.
(4) Inspect the breaker compartment and cam follower.
(5) Inspect the breaker points for serviceability and check the breaker points gap, magneto engine timing and synchronisation.
(6) Inspect the switch and earth leads.
(7) Refit and torque the spark plugs.
(8) Refit the spark plug high tension leads.
Do you see anything explicitly mentioning magneto 500hr inspections?
This paragraph is at the start of the schedule 5 text.
(You say there is nothing saying in schedule 5 you must do components?)
"6.7 Except where otherwise approved or directed by CASA the procedures and limits prepared by the aeroplane manufacturer are to be used when performing an inspection required by this schedule." (Schedule 5)!
I don't think you will find too many LAME's out there that will sign out a magneto that is past it's 500hr inspection limit, I certainly wouldn't, and for bendix, yes I'm afraid in will do the 4yearly also.
But Dukes fuel pumps?
Vac pumps?
Yeah, your right, let's let them go so they fail right when you need them most.
Even though you as a registered operator are responsible that all maintenance is
Bla Bla Bla... You already know.
Let me ask you this, say you have a 182 with a McCauley, under AD/Prop/1, would you operate
It with no consideration to calendar, because it's hours only. Or would you take my advice to
Do it in accordance with the manufacturers timeframe, or do you require some pic's of corroded or failed hubs, the former means a lot more parts in the bin, the latter means.....
You keep referring to human factors without saying it, it is obviously a part of everything
We do, it should not be used as a reason, to not do something, however unnecessary you think
It is.
Quote:
"An experienced maintainer will know how and when to do more of the necessary maintenance and less of the unnecessary maintenance. Schedule 5 will give you more flexibility to do that"
First part, Not worded how I would put it, but I sort of agree,
But saying schedule 5 gives you more "flexibility" is a furphy..
I believe from a CASA insp.
""However, CAR 42V requires persons undertaking maintenance (including inspections) to do so in accordance with applicable maintenance data. CAR 2A(2)(c) defines such data to include instructions issued by manufacturers of aircraft, components and materials.""
Same old argument.
