Question

Larry... not too sure what your trying to do here...

The 100 hr inspection is for any aircraft that has flown that long... and the inspection data is listed in the front section of the service manual... where all the little dots and times for things to be done are... now their are things that should be done before the 100 hrs... i.e. like every 25 hrs, 50 hrs... etc... you need to take a look at these things ... and make sure that they are being accomplished...


Now your mechanic is right... unless you have 100 hrs on the aircraft since the last inspection... then you don't need to do it... until a year has pass since the last annual inspection... again if you have flown more than 100 hrs... you need the 100 hr inspection that he can do... along with your help... but, if for instance you only flew 75 hrs... then you need only look at the last annual date... and count 12 months from it... remember your annual goes south on the last day of the month so you can actually get 13 months in... if you time it right... i.e annual was signed off on the 1st of January... your next annual is due on the 31st of next January....or 12 months plus 30 days... if however you finished and your annual was signed off on the 20th of January... it expires one year later on the 31st...

Now as to lubes and other things... thats a pilot thingiee... and once he shows you how... you can peform routine maintance... so long as you don't have to take anything appart that requires a torque value or safety wire... (with the oil filter and drain plug being the exception)

So you need to keep an eye on the time from last annual... in months and also the time in hours ... because you are not supposed to go over 100 hrs between inspections...

the 100 hr is routinely done along with the annual with the mechanic preparing the plane and the IA doing the inspection after he is done... most of the time it is done concurently... with the IA supplying the mechanic (A&P) with all the things that should be looked at that he has gotten problems on...

However, the 100 hr inspection can be done just by a A&P and returned to service... it is only the annual that requires the IA to sign off...

Now this is for the part 91 operation... you are not flying for commercial operation under part 121,125,135or 141... if you are a private pilot... and thus the only rules that apply are part 91, 61 and 43 for the mechanical...

It gets confusing about commercial ratings vs the parts that you can fly under... along with the ATP rating... but, yes you can be a air carrier and use your skymaster... parts, goods and services are all listed under the different parts... and if you are..then you need to discuss the aspects of annual vs contenual progressive inspection... which you can read about in the service manual... with your local FAA office... but, most of us who use the plane for pleasure... under the GA rules... are operating on the part 91 stuff...
