Special Light-Sport Aircraft (S-LSA)
FAA regulation Title 14 CFR 91.327 specifies who can perform what maintenance and inspections on S-LSA. This regulation specifies that the manfacturer determines all the details of who can do what on the specific components, not the FAA. Here the manfacturers let the owner do some tasks, or an officiel FAA repair station, or for some tasks they require the FAA certified mechanics, (A&P) to have official manfacturers training on the components. An example of this would be maintenance on a ROTAX engine.
Airplane special light-sport aircraft (S-LSA) must be maintained by FAA certified mechanics, (A&P) with the exception of some preventative maintenance. This “preventative maintenance” can be done by the owner/operator, but is specifically defined by the manufacturer in the aircraft “Maintenance and Inspection Procedures Manual” provided with each S-LSA. Typically, the owner is allowed to inspect items and add fluids such as oil, coolent, and hydraulic fluid. Minor maintenance items such as changing oil, spark plugs, tires, may or may not be allowed for the owner/operator to perform for S-LSA.

Experimental Light-Sport Aircraft (E-LSA)
Airplane experimental light-sport aircraft (E-LSA) are completely different. FAA regulation Title 14 CFR 91.319 does not mandate that FAA certified mechanics maintain E-LSA, except for some special situations.    Anyone can do maintenance on an E-LSA. If you want to do your own aircraft maintenance, this may be a very good reason to purchase an E-LSA. S-LSA can be transitioned to E-LSA if necessary, however, the aircraft would than not be able to be rented out or used for commercial training.  You, (The Owner) can, with training, do many of the maintenance and repairs yourself. You may find that you already have many if not all the tools necessary to do the job.

When you buy a new airplane LSA you can usually have this work performed by the dealer. When you buy a used LSA you may be on your own as warranties are seldom transferable and the original dealer usually has no obligation to support you.

FAA Certified Standard Category Aircraft
It should be noted that FAA certified standard category aircraft (classics such as some Piper Cubs, Talorcrafts, Lyscombs, etc.), must be maintained only by A&P Mechanics or FAA repair stations. The new LSA rule has not changed the maintenance requirements for these standard category aircraft.

Inspections

All  light-sport aircraft (LSA) require an  condition inspection every year by a FAA certified repairman, an A&P or Repair Station. For E-LSA, you can do this yourself if you take a 16 hour class for your category of aircraft. If you elect NOT to take the class, then you’ll need to find someone qualified to do this condition inspection.

LSA Repairman Certification

The FAA instituted a new LSA repairman certificate called “Repairman – Light-Sport Aircraft”. There are two ratings for this certificate: Inspection and Maintenance.

LSA Repairman Inspection Rating
This rating allows you to conduct the condition inspection on an E-LSA you own. It requires the successful completion of an FAA accepted, 16-hour course on the inspection of your particular class of LSA.

LSA Repairman Maintenance Rating
The Maintenance (120 hour) rating is a commercial rating allowing you to maintain, repair, and perform the condition inspection on all special light-sport aircraft (S-LSA) and condition inspections on experimental light-sport aircraft (E-LSA) for hire, within the class of aircraft shown on your certificate. The repairs and maintenance you can perform on S-LSA are specifically authorized in the aircraft manufacturers’ maintenance manuals.

A&P Airframe and Powerplant Mechanic is the  FAA certificated mechanic who can work on LSA, standard category LSA and heavier aircraft that do not meet the LSA criteria. These are the mechanics that were and still are authorized to maintain aircraft before the new LSA rule was inacted.

Who can do what?

First it must be determined what type of aircraft you have, then in the table below, it can be determined what type of maintenance and inspections can be done by whom on what type of Light-Sport Aircraft (LSA).

* Simple “Preventative maintenance” as specified by manufacturer can be done by the owner and operator of a S-LSA with a Sport Pilot or higher certificate.

** Maintenance is a common term but it is not used here because the FAA uses the word “Maintenance” to refer to a specific level of service required by properly trained mechanics.

*** Simple “Preventative maintenance” as specified in FAR Part 43 can be done by the owner and operator of the aircraft with recreational pilot and higher certificate.

A&P is an FAA certificated Airframe and Powerplant Mechanic.

A&P, IA is an FAA certified Airframe and Powerplant Mechanic with Inspection Authorization.
