The course is taught by Mike Grabbe, who taught the Twin Commander maintenance course at FlightSafety International for more than six years, and is now Technical Advisor and Manager of Training for Eagle Creek Aviation Services in Indianapolis.

Course content includes:

•Familiarization with component locations.
•Introduction to normal systems operation leading to analyzing system malfunctions in a cost-effective manner.
•Discussion of recent manufacturer’s service information and product updates.
•Opportunities to share maintenance experience with other course participants.

Actual hours spent on each subject vary depending on the experience of class participants and the topics discussed.

The training is conducted at Eagle Creek Aviation Services in Indianapolis, where Grabbe and students can simply walk a few steps from the classroom to the busy shop floor to examine airplanes and components in various stages of maintenance and upgrades.

Twin Commander Aircraft recommends that maintenance personnel attend update training at least every 12-18 months to ensure continued technical competency and accuracy of maintenance-related information.

The class culminates with a 100-question graded exam. Technicians who successfully complete the class each receive an official certificate and record of training.
