Stupid questions from new owner

by Darren Pralle in 912 / 914 Technical Questions 7 years ago

Hello folks,

We recently purchased an RV-12 S-LSA and I'm trying to figure out a few things relative to ongoing maintenance and service bulletins. Any help is appreciated.

1. Given that the airplane is an S-LSA, what maintenance can I do myself?
1a. If I attend the Rotax 912 Series Service class, does the answer to Question 1 change and to what extent?

Say I want to do an oil change. Can I? Do I need the 912 Service class?
Say I want to change the spark plugs? Same question...

2. I see two SBs about carb floats (SB-912-065 and SB-912-067). If the floats are changed per SB-912-067, is the 25 hour inspection still required? -065 has two notes. One says exchange of floats eliminates the requirement to inspect every 25 hours. Two paragraphs later, it says that inspection of floats must continue even after the floats are replaced. ??!?!?!!!! Color me confused.
2a. If continued inspection is required, can I do that inspection myself as an owner?
2b. If I take the 912 Series Service class, does the answer to 2a change?

Thanks!

If you operate a US registered S-LSA you need an FAA certificate to do any work on the aircraft. The exception is specific tasks the aircraft manufacturer allows an owner to perform.

You can take a 120 hour course and earn an FAA certificate for a "Repairman Light Sport-Maintenance" or (LSRM-A). With this rating you can do the condition inspection and 100 hour inspection on any S-LSA or E-LSA airplane. You can preform any work on an S-LSA airplane, LIMITED by the scope of the Maintenance Manual(s) or manufacturers approval. You can not do a condition inspection on an amateur built version of an LSA and you can't work on any TC'ed aircraft.
Don't confuse this with The 16 hour course. This gets you an FAA certificate for a "Repairman Light Sport Aircraft -inspection" rating or (LSRI-A) With this rating you can ONLY do the condition inspection on an E-LSA you own.
This rating is completely useless if you own a S-LSA.

By contrast, the three 16-24 hour Rotax courses get you a Rotax diploma that expires in 24 months and a nifty Rotax ID card. If you own an S-LSA, and didn't take the 120 hour course, you CAN'T use this diploma to sign off work that requires an FAA rating.

"You can not do a condition inspection on an amateur built version of an LSA and you can't work on any TC'ed aircraft."

I think You can do the condition inspection on an amateur built version of LSA. But if you own it and didn't build it, you must get someone else to sign it off. Or thats what they teach in school.

You are correct, provided you built that aircraft AND you hold the "one time" FAA Repairman certificate for that one aircraft. This certificate will have a limitation to make, model and serial number. You may continue to do condition inspections on this single aircraft after you sell it, for the remainder of you life. This certificate is non-transferable, it dies with you.

My comments were intended to show the limitations of the FAA LSRM-A certificate, an FAA builders repairman certificate is a separate rating. Not all repairman ratings are equal.
