Study Notes

Aircraft Maintenance & Repair

Major Repair is considered a significant repair operation requiring extensive disassembly and potentially replacement of components.
Major Alteration refers to changes to the basic design of an aircraft or component that could impact its airworthiness.
Minor Repair is a less complex repair that doesn’t involve significant disassembly or modification.
Minor Alteration involves minor modifications to the design of an aircraft or component that don’t affect the overall design or airworthiness.
Preventive Maintenance involves routine inspections, cleaning, and lubrication to prevent potential issues before they occur.

Airworthiness & Regulations

14 CFR Part 21 governs the issuance of airworthiness certificates for aircraft.
Airworthiness Directives are mandatory safety instructions issued by the FAA regarding specific aircraft models or components.
Annual Inspection is a comprehensive examination of an aircraft's airworthiness, including inspection of instruments and operation systems.
General Aviation Airworthiness Alerts are advisory publications with maintenance information, but compliance is not mandatory.
Return to Service is a document signed by a certified mechanic after completing a maintenance operation, ensuring the aircraft meets airworthiness standards.

Mechanic Responsibilities & Certifications

A certified mechanic is responsible for ensuring the aircraft receives appropriate maintenance and inspection.
A certified powerplant mechanic can perform minor repairs on aluminum propellers and release them for service.
A mechanic with a powerplant rating can perform 100-hour inspections on powerplants, propellers, or their components and release them for service.
PCAR Part 6 governs Maintenance Repair Organizations/ Approved Maintenance Organizations
The operator is responsible for ensuring the aircraft’s maintenance records are up-to-date.

Penalties & Sanctions

The PCAR Part 1 table of sanctions outlines penalties for various violations, including improper release of an aircraft and falsification of records.
Falsification of maintenance records is a serious violation that could result in revocation of a mechanic's certificate.

Specific Components & Maintenance

Installation of propeller de-icing systems is considered a major alteration to the propeller.
Propeller alterations are considered minor if they involve simple design changes or relocation of brackets.
Replacing or cleaning spark plugs and adjusting the spark plug gap is classed as preventive maintenance.
Overhaul of pressure-type carburetor mechanical accessories is considered appliance major repair.
Repair operations on hydraulic/pneumatic accessories and disassembly of complex hydraulic/pneumatic power valves are considered appliance major alterations.
Disassembly of float-type carburetors is not considered a powerplant major alteration.
Simple fabric patches on control surfaces are considered preventive maintenance as long as they don’t involve rib stitching or structural parts.
