Study Notes
100-Hour Inspections
- A 100-hour inspection is required by the FAA for powerplants, propellers, and their components.
- The inspection must be performed by a certified mechanic and documented in the aircraft's maintenance records.
- The mechanic must ensure that the aircraft meets all applicable regulations and standards before it can be returned to service.
Maintenance and Repair
- Maintenance includes all work performed to keep an aircraft, engine, propeller, appliance, or component in a safe and airworthy condition.
- Repair is any work that restores an aircraft, engine, propeller, appliance, or component to an airworthy condition after it has been damaged or worn out.
- Preventive maintenance includes routine work like oil changes and inspections to prevent major repairs down the line
- Major repairs can include complex operations like overhauling engines or propellers.
Airworthiness Directives
- Airworthiness directives (ADs) are mandatory instructions issued by the FAA to address safety issues with aircraft, engines, propellers, appliances, or components.
- They require specific maintenance actions to be taken to ensure the continued airworthiness of the aircraft.
- ADs are based on safety issues that have been identified, including accidents, incidents, and engineering investigations.
- ADs are not optional, and pilots and mechanics must comply with all applicable ADs.
Propeller Maintenance
- Propellers have their own specific requirements for maintenance, including inspections, repairs, and alterations.
- Major repairs may include the disassembly of complex components, such as the propeller hub.
- Minor repairs can include simple tasks like replacing a damaged blade.
Maintenance Records
- All maintenance, repair, and alteration work must be documented in the aircraft's maintenance records.
- This includes the date of the work, the type of work performed, the mechanic's name and certification number, and any parts that were replaced.
- Accurate maintenance records are critical for ensuring the safety and airworthiness of the aircraft.
- They also provide a history of the aircraft's maintenance, which can be used for future maintenance planning.
Airworthiness Certificate
- An airworthiness certificate is a document that certifies that an aircraft meets all applicable regulations and standards and is safe to fly.
- An aircraft must have a valid airworthiness certificate in order to be operated.
- The issuance of an airworthiness certificate is governed by 14 CFR Part 21.
Maintenance Organizations
- Approved Maintenance Organizations (AMO) can perform maintenance, repair, and alterations on aircraft, engines, propellers, appliances, and components.
- PCAR is part of the Aviation Safety Regulations in the Philippines
- PCAR part 1 governs the table of sanctions for MRO/AMO operations.
Sanctions and Penalties
- Significant sanctions and penalties exist under PCAR for violating aviation safety regulations.
- Specifically for MRO/AMO operations, the penalties can range from suspension, fines, and in the most serious cases, revocation of operating privileges.
Other Key Points
- The operator is responsible for ensuring that maintenance information is up to date.
- An aircraft that fails an annual inspection must obtain a special flight permit to fly to another maintenance base.
- Modifications to the basic design of an aircraft must be authorized by the manufacturer or the FAA.
- The aircraft manufacturer's maintenance manuals and propeller manuals are key sources of information for maintenance, repair, and alterations.
