AMM Example Use – ATA Chapters in Aircraft Maintenance

AMM – Example Use

The Aircraft Maintenance Manual (AMM) organizes maintenance procedures using ATA chapter numbers, which makes it easy for engineers to locate relevant tasks for each aircraft system.

ATA chapters in the AMM guide line and base maintenance engineers for system-specific maintenance tasks.

Example ATA Chapter Usage

• ATA 29: Hydraulic system procedures
• ATA 32: Landing gear maintenance
• ATA 21: Air conditioning system

These chapters provide step-by-step instructions, troubleshooting guidance, and removal/installation procedures for each system.

---

Who Uses These Instructions?

• Line Maintenance Engineers: Perform routine inspections and minor defect rectification at the airport
• Base Maintenance Engineers: Conduct heavy maintenance, in-depth system checks, and component overhauls in hangars

By following AMM procedures based on ATA chapters, maintenance personnel ensure aircraft safety, reliability, and compliance with aviation regulations.

Conclusion

Using ATA chapters in the AMM allows maintenance engineers to quickly access approved procedures for specific aircraft systems. This structured approach is essential for efficient, safe, and standardized aircraft maintenance.
