Due to a big demand this class is back. Prepare to learn and have fun doing it!

This is an improved service level class that will raise and improve the 100 hour and annual inspection understanding. It will guide people to perform at a higher level of education and knowledge base whether you are a private owner or a mechanic. After discussions and feedback with the students that have taken this enhanced Service class with mostly hands on instruction they feel like they are capable of performing at a higher level with inspections, performing simple service work and documenting in the logbook over some other service classes. This class will have a couple hours of classroom each day, but the majority of each day is all hands on work with a functioning Rotax 912ULS and a 912iS engine and targeting the 100 hour / annual inspection and general service work. We will perform an actual annual inspection on a functional aircraft and every student will be supplied with an inspection checklist. We will demonstrate and perform other service functions. While working you will be able to ask real time questions and take notes to help your understanding of the work when you return home. This will empower owners and mechanics to perform better 100 hour and annual inspections, better DOCUMENTATION, and service-based maintenance on the 912 engines. This class will expand on the already successful Rotax Service class by incorporating more hands on time, but more importantly it will expand on better logbook documentation and will focus on a more detailed and proper inspection process while performing service-level work on the 912 UL, ULS & iS class engine and the 914 engine. This enhanced class will help reduce maintenance induced engine problems and simple time consuming inquiries to the Rotax distributors’ and owners’ maintenance based questions.

The new Expanded Inspection Service Class and associated demonstrations will include, but not be limited to:

Classroom instruction: each day is 3-4 hours of classroom with engine part props

(Each student to bring a laptop, IPAD or similar media device)

Registering engines

Finding current manuals on the different internet sites

How to use each manual and its content

Having students demonstrate where to find appropriate documentation for given problems

Service Bulletins and related document recovery from the internet

Understanding Service Bulletin and related material

Understanding what is included in the required 25 hour warranty inspection and its importance

Parts’ time limits and their importance

Check list locations, usage and their importance (Inspection check list)

Logbook entries, their importance and the proper way to log engine information

Researching and use of proper fluids (Loctite, oils, lubricants and fuels)

Hose change and its challenges. (The why’s and how’s)

In hangar work and hands on ramp demonstrations: (approximately 12 hrs)

Following and using the Line Maintenance 100 hr. and Annual check list. (each student will be issued a checklist)

Proper hose inspection and its importance

Proper use of hose clamps, clamping techniques and the tools. Types of clamps and demo each including Oetiker, Band-It, fuel injection clamps and the constant compression spring clamps.

Wiring inspections and what to look for with minor trouble shooting on a few common wiring problems.

  • Water pump weep hole inspection and what to look for. Information on what to do if coolant is found on the floor from this area.
  • How to perform an actual oil purge and its proper technique and why this is so important.
  • Discussion on draining and re-filling the cooling system
  • Applying heat and vibration shields and what constitutes vulnerable areas.
  • Remote mounting the oil pressure and or fuel pressure sender
  • How to remove pins from plastic wiring connectors (i.e. the ignition modules and regulator/rectifier)
  • Gearbox friction torque test and how to locate the TDC mark
  • Perform a differential compression test and discuss its indications
  • Proper K&N air filter cleaning and oiling
  • Full class involvement in how to do a mechanical carb sync and a pneumatic sync and how to diagnose carb problems with gauges
  • Carb inspection and weighing floats
  • Proper spark plug gapping and thermal paste application.
  • Oil pressure regulator installation. (plug screw, spring and mushroom)
  • 90 degree coolant elbow inspection for leaks and proper leak repair
  • Gearbox removal and installation. We will disassemble a gearbox just to allow students to see its interior parts operation (no maintenance, just prep for shipping to a distributor)
  • Trouble shooting low fuel or oil pressure problems. (How to set up an inexpensive test gauge)
  • Possible Tanis or Reiff pre-heater application
  • Fuel pump replacement
  • Removal and cleaning of the oil tank
  • Safety wiring the oil pressure regulator plug screw, magnetic plug, air filter and throttle cables when needed
  • Cutting and inspecting the oil filter (how to wash it for better results)
  • Header Wrap installation discussion. The do’s and don’ts.
  • Proper exhaust spring inspection, installation, including safety wire and proper application of high temp silicone
  • Proper prop pitch setup demonstration. This seems to be a big one for many people. Many owners and A&P’s don’t know how to do this and it’s important for the engine.
  • Oil and oil filter change and catching an oil sample for a lab analysis. Venting vs Purging
  • General Trouble shooting (questions & answers)

Hi All,
It's getting closer to class time and slots are closing up. If you own a Rotax engine you should take a Rotax service class that will teach you all the everyday maintenance , but with our class we not only cover that, but we use a Rotax inspection checklist and go down that item by item. Plus we get into hoses, hose change, clamps and how to adjust your prop the proper way. We delve deep into carb sync and what the gauges are telling you and we do real time carb syncs. You'll learn how to diagnose with gauges. We work on a live aircraft / engine.
What's really unique about this class is we keep the class size small at 10 students because you all will be turning all the wrenches and screwdrivers for the annual checklist.
Because of he way we teach, work on the engine, do an annual on an engine and have all the students do the work this will answer all your Rotax questions and since you are doing all the work you will remember more from this class.

There is no way you can attend this class and not learn things.
