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. Explores unducted fan systems and engine removal and installation. 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 completion of the course 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 “C” (minimum 76%) or higher is required for this course to be creditable toward the FAA authorized CERTIFICATE OF COMPLETION.

Related Instruction

Computation
Hours: 10

  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.

  1. Instruction on and student practice in measuring blade angles using a propeller protractor.

  2. Plan and perform repairs of damaged propeller blades by using the math formulas found in government and manufacturer’s publications, as applicable, and record the data; determine if the damage is within limits or not airworthy.

  3. Measure blade angles on fixed and variable pitch propellers using Vernier and/or digital protractors; determine if within specifications or not airworthy.

Communication
Hours: 12

  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.

  1. Instruction and skill development in reading, interpreting, and understanding the government regulations (laws) and advisory publications that affect the repair and alteration of propellers.

  2. Use of aircraft manuals and parts catalogs in the process of performing maintenance, disassembling, and reassembling propellers.

  3. Interpret the results of non-destructive inspection testing performed on propellers, aircraft engine mounts, and engine mounting bolts, etc.

Human Relations
Hours: 10

2. Identify and apply acceptable aviation maintenance standards during the performance of aircraft reciprocating engine removal and installation, testing
and adjustment.

  1. Direct instruction, supervised student skill development, and lab practice on the teamwork and cooperation required to remove and install aircraft engines and perform post-maintenance operations (“run-up”), with a special emphasis on the human relations components of co-worker and customer safety.
