Course Description

Examines propeller theory and repair within limitations imposed by FAA Regulation Part 65, plus control and auxiliary systems, such as anti-ice and synchronization. Unducted fan systems are explored and engine removal and installation are accomplished. Prerequisites: AMT 102, AMT 203, AMT 204, AMT 105, AMT 106, AMT 107. Audit available.

Addendum to Course Description

This course is part of a Program designed to meet some of the requirements of the Code of Federal Regulations (CFR) for certification of Aviation Mechanics, and approved by the Federal Aviation Administration (FAA). Upon completion of the Program, the student should be able to:

  1. Meet the identified Degree and Certificate Outcomes identified in the document found at http://www.pcc.edu/resources/academic/degree-outcome/amt.html as appropriate for coursework level completed.
  2. Successfully complete FAA Knowledge testing, in a written test format, as identified in the document:    FAA-G-8082-3A - AVIATION MAINTENANCE TECHNICIAN€”GENERAL, AIRFRAME, AND POWERPLANT KNOWLEDGE TEST GUIDE
  3. Successfully complete FAA Knowledge and Skill testing, in an oral and practical test format, as identified in the following documents, as appropriate:

a.FAA-S-8081-26 -AVIATION MECHANIC GENERAL - Practical Test Standards

b.FAA-S-8081-27 €“ AVIATION MECHANIC AIRFRAME €“ Practical Test Standards

c.FAA-S-8081-28 €“ AVIATION MECHANIC POWERPLANT €“ Practical Test Standards

Intended Outcomes for the course

Upon successful completion students should be able to:

  1. Identify and apply all current manufacturer service information, and other airworthiness requirements including airworthiness directives during the performance of maintenance and inspection of aircraft fixed and variable pitch propellers.
  2. Identify and apply acceptable aviation maintenance standards during the performance of aircraft reciprocating engine removal and installation, testing and adjustment.

Course Activities and Design

Lecture/discussion/demonstration sessions and lab projects, supported by written instructional materials, will present to the student background knowledge needed at entry level for related aviation maintenance employment, and needed to perform the written, oral, and practical tests which are required for FAA certification of Aviation Mechanics. The assignment of four credit hours to this course indicates that students will be involved with the course content for approximately 120 hours. Class participants will be expected to invest time outside of the official scheduled class hours in their efforts to master the course content. For this course to be creditable toward the FAA authorized CERTIFICATE OF COMPLETION, the total hours recorded for the course must not be less than 90% of the hours offered during the module (typically 90 hours). Material missed by students during allowed absence will be made available to them in one or more ways, as selected by the instructor. THE STUDENT IS RESPONSIBLE FOR CHECKING WITH THE INSTRUCTOR FOLLOWING ANY ABSENCE, AND FOR ACCESSING THE MISSED MATERIAL THAT IS MADE AVAILABLE.

Outcome Assessment Strategies

Evaluation methods include written and oral testing, attendance and class participation, and satisfactory completion of class projects. Evaluation levels will be at least those defined in FAR Part 147 Appendices and in this Course Content Guide. A letter grade of €œC€ (minimum 76%) or higher is required for this course to be creditable toward the FAA authorized CERTIFICATE OF COMPLETION.
