Rotax Enhanced Annual and Service Class Oct. 15th & 16th, 2022


Recommended Posts

Here is a new enhanced Rotax class that everyone has been asking for its return. For a change I could use some help. I need help in spreading this out to other forums since I'm not on as many forums as others here. Please spread the word and copy and paste to other aircraft web sites.

Thank You

  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  roper inspection process while performing service-level work on the 912 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:
