Preventive Maintenance

Preventive maintenance ensures aircraft safety by identifying and addressing issues early. Technicians perform tasks like running system tests, lubricating parts, and replacing components following 14 CFR Part 43 Appendix A guidelines.  Regular inspections—such as preflight checks, 50-hour, 100-hour, and annual reviews—are critical for this process.

Benefits include improved reliability, enhanced safety for pilots and passengers. Aircraft maintenance technicians use power tools and diagnostic equipment during these procedures to maintain optimal performance in aircraft engines.

Corrective Maintenance

Corrective maintenance focuses on fixing issues after a failure or malfunction occurs. Mechanics repair, replace, or alter components to return the aircraft to airworthy condition.

For minor repairs, an approved aviation maintenance technician can log and sign off the work without complex approvals. Major repairs require approval from an authorized body based on specific regional protocols. This type of maintenance ensures safety by addressing detected anomalies in systems or structures. For instance, identifying and repairing hydraulic leaks promptly prevents further damage. Military aircraft also undergo corrective actions due to their demanding operational environments. Repair stations equipped with certified tools handle such tasks effectively while ensuring compliance with FAA-approved guidelines. 

Line vs. Base Maintenance

Line and base maintenance are critical components of aviation maintenance. Each serves different purposes to ensure aircraft safety and reliability.

  1. Line maintenance includes routine tasks completed before, between, or after flights. These quick checks aim to address minor issues and keep planes airworthy. 
  2. Base maintenance involves more extensive work such as engine overhauls and structural inspections. These repairs often take days or weeks to finish.
  3. Line maintenance typically ensures compliance with the Minimum Equipment List (MEL). This prevents small problems from escalating during flight operations.
  4. Highly trained aviation mechanics perform both types of maintenance under FAA-approved guidelines. They follow strict safety standards to protect passengers and crew.
  5. Line maintenance focuses on immediate needs like inspecting tire pressure or replacing worn parts quickly. It helps reduce unexpected delays for airlines.
  6. Base maintenance occurs less often but includes comprehensive repairs that extend an aircraft's lifespan. These include addressing major system malfunctions or corrosion repairs.
  7. Preventive efforts in line maintenance improve efficiency by preempting potential risks before flights even begin boarding.
  8. Conducting base-level work ensures long-term performance and adheres to aviation safety regulations set by authorities like the FAA or EASA.

Both types play essential roles in keeping planes safe for travel while minimizing downtime effectively, preserving operational schedules across various fleets worldwide.

  • The 100-Hour Inspection applies to aircraft used for hire or flight instruction. It ensures these planes are safe and reliable for repeated use. 
  • Progressive Inspections are ideal for operators needing minimal downtime. They allow inspections in smaller segments over time instead of all at once.
  • Prepurchase Inspections occur before buying an aircraft. These assessments verify its condition and maintenance history, preventing costly surprises.
  • Specific tests analyze vital systems like altimeters, transponders, and ELTs. Regulations such as FAR 91.411 and FAR 91.413 govern their inspection intervals.

System diagnostics and repairs follow applicable inspections to address identified problems or defects.

System Diagnostics and Repairs

System diagnostics and repairs ensure that aircraft remain reliable and safe for operation. Technicians use advanced tools to detect and fix issues quickly, keeping planes airworthy.

  1. Engineers perform system checks using remote diagnostic tools like the Aviation Diagnostics and Maintenance (ADAM) System. These tools provide real-time data on engine performance, hydraulics, and electrical systems.
  2. Faults detected during inspections require immediate action to prevent larger problems. Examples include replacing faulty wiring or repairing a malfunctioning hydraulic pump.
  3. Diagnostic software identifies specific issues with sensors or onboard computers. This helps maintenance workers pinpoint failures in navigation systems or communication devices.
  4. Repairs often involve removing damaged components such as powerplant mechanics working on engines or technicians replacing critical airframe parts.
  5. Maintenance teams conduct post-repair tests to verify that repairs meet FAA-approved safety standards before the aircraft resumes service.
  6. Record-keeping tracks all system diagnostics and repair activities for compliance with regulatory bodies like the FAA and EASA.

Understanding these tasks leads to mastering preventive maintenance we covered in the Preventive Maintenance section.

Record-Keeping and Compliance

Accurate record-keeping ensures aviation safety and FAA compliance. Title 14 of the Code of Federal Regulations (CFR), Parts 43 and 91, mandates detailed maintenance records.  These records must include a description of the work performed, the completion date, and the signature of the technician responsible. Proper documentation helps verify that aircraft meet airworthiness standards. Maintenance logs play a critical role in inspections and repairs.
