Maintenance Schedule
 

I had been a owner pilot of a non-hiring Mooney for the last 4 years. Now because I normally fly approx 100 hours a year so my annual always coincides with 100-hourly conveniently.

But now the work dictates that I will be flying around 250 a year, what choice do I have when it comes to maintenance schedule?

In US, as long as the plane is not for hire, there is no requirement for 100-hourly at all. AFAIK, it's not the case in Australia (yet another example of how CASA thinks it knows better than FAA). Is that true?

FlyDoc

Yes that is true. Speak to your maintenance provider about which schedule is best for your situation.

At 250 per year I'd still go for the 100 hourly think of it as preventive maintenance.

This way the aircraft won't let you down when you most need it

Private maintenance
 

Actually our rules are exactly the same as the US. No need to do 100hourly inspections on private aircraft using CASA maintenance schedule. See CAO 100.5 (7.3)
7.2
"Subject to regulation 47 of the Regulations and paragraph 7.3, a maintenance release for a class B aircraft remains in force for whichever of the following periods ends first:

(a) a period not exceeding 1 year;

(b) the aircraft time-in-service that is identified by the certificate of registration holder in the aircraft’s log book statement as the period for which the maintenance release is to remain in force.

7.3 Subparagraph 7.2 (b) does not apply to private class B aircraft being maintained to the CASA Maintenance Schedule."

All AD,s must not exceed their limits though

I also think 250 hours is stretching things a bit. Maybe do the inspection at around 125 hours would be better if you are going to do 250 hours p.a.

CAsA Schedule 5 requires you to do every item of maintenance that the manufacture calls up at its interval times.


So every 25,50 or 100 hr items & calendar time items are also due.

CAsA Schedule 5 does not exempt you from any time limit maintenance in the manufactures manuals (all of them A/F, eng, prop and every component on the aircraft from every manufacturer).

So keep in mind many small craft work on 100 hrs cycles on most of the engine and airfame - some larger have items due 200 - 400 for inspections. So on CAsA shed 5 the 200-400 will not be required if you do 199 hrs in 12 months.

* On a side note all maintenance due to be put on the MR is pretty hard for a Shed 5 if you list all due items - on open hours. For this reason I always had expire hours, but I have seen many N/A with no maint due entered.

So if you have any 100.5 inspections on your 100hourly then no matter what you do you will,have to comply with these, hence 100 hours or 12 months

I am pretty sure 100.5 inspections give a time - but if the manufactures also give a time for the same inspection, then the manufactures time limit must be used.

FlyDr, I wrote you a longer PM but I cannot PM you. I'll pull out some points:

The regulation you are looking for is in CASA Schedule 5 of the CAR at paragraph 2.3:
That's it. Just make sure your log book statement doesn't say "12 months or 100 hours", Just 12 months.

Remeber CAR 41 says:
That makes YOU responsible for the maintenance of your aircraft, despite what the LAME may tell you. You can issue your own Log Book Statement on the relevant forms, despite what they tell you, this job does not belong to the engineer.

Remember the majority of Schedule 5 is a "shopping list" of inspections that apply to your aircraft, not so much an actual doing list (eg change this, change that). If you are happy to not have the aircraft "inspected" every 250 hours, that is your choice and in your legal right to do so. That is why there is a PRIVATE category.

Get hold of a copy of the maintenance manual for your aircraft. Try google. You will find some interesting things in the MM. It may even disagree with what your engineer has been telling you all this time. The Cessna SIDS document on 100 series Cessna's is a prime example.

Learn how to do the schedule 8 items yourself if that floats your boat. CASA like you to have been signed off by someone who is competent (a LAME).

Yes - AD's must be complied with, including AD ENG4 every 100 hours. These can be re forecast on the same MR for the next 100 hours.

Hope this helps,

100.5 items are now so varried its almost impossible to understand. Were we once have simple ad,s that were simple to understand we now have a document that like reading war and peace. This now has the reverse of what aopa pushed for with the introduction of 100.5 and the removal of ad,s. Takes 5% of brain power for a change and 200% to see were that change is going to take you. Aopa obviously didnt have that 200% si now we have just about an unworkable document.

If no time limit is given by the manufacturer then yes you can push it to 250 hours - but if the manufactures maintenance manual says every 5 hours, then even under schedule 5 it MUST be done every 5 hours. It is not an option!

Connedrod yes 100.5 has been the bin, to put everything in to keep the things CAsA wont part with - that can not be included in the new rules. It is a mess.

Would you be able to provide me with a regulation for this?

You've suddenly put out of the air every aircraft that has not had a prop (AD Prop 1) and governors overhaul every 6 years, Every aircraft that hasn't had new hoses fitted every 5 years, every aircraft that has an engine past 12 years since overhaul, actually most aircraft maintained on schedule 5.

I think you may be confusing items listed as airworthiness limitations which are applicable to the type certificate, not maintenance schedules listed in the maintenance manual.

Haydn

Do yourself a favour, Haydn: It isn’t worth your while making eye contact.

AD's overrule any other publication.


CAsA AD is number 1 in the list of the order - Aircraft manufacturer is # 2.


I HAVE NEVER SAID ad'S ARE NOT PART OF WHAT NEEDS TO BE DONE - IN FACT THE OPPOSITE.

Sorry caps lock and lazy to type again

AD/ENG/ 4 think it is - excepts allish as you list - Why because it is an AD.

If you have a starter or turbo or mag inspection on hours - they are still due.

Bend alot and Connedrod,

Friday, I'll be again spending the night at the Criterion Hotel at Crookwell. I invite you both to have breakfast with me in the morning, at my expense.

(Sadly, my technical skills were deficient and one of the wind farm generators is still faulty.)

yr right's welcome too.

Conned Rod,
What on earth are you talking about, and what did AOPA have to do with it.
Removal of ADs ??? 200% si ??
Tootle pip!!

As i have said before im not in crookwell. How ever i cant say for the other two im guessing you think they me but alass not

I thought so. Is Connedrod really yr right?
