The 787 features significantly extended maintenance intervals compared to previous generations. Line Checks : Typically occur every 1,000 flight hours Base Checks (C-Check) : First base check is targeted at or 36 months. Heavy Maintenance (D-Check) : Due every , compared to 6 years for older types. Essential Referenced Documents
The electrical system operates at 235 Volts AC, which is significantly higher than traditional commercial aircraft. Always follow the specific lock-out/tag-out procedures outlined in ATA Chapter 24 before opening electrical distribution panels. Strict Tool Control
: Critical updates and modifications from the manufacturer. High-Priority Maintenance Areas
This application dynamically links the AMM with structural repair data, fault isolation trees, and parts catalogs. A technician can click on a fault code generated by the airplane, and the software automatically populates the exact step-by-step AMM removal procedure and required tool listing.

This dictates the inspection intervals for major components, ensuring compliance with scheduled maintenance requirements.
The B787 AMM organizes data using the standardized ATA (Air Transport Association) 100/iSpec 2200 chapter numbering system. However, due to the Dreamliner's unique "more-electric" design, specific chapters carry much higher operational weight than they do on older aircraft models.

It is, quite simply, the most intelligent maintenance manual ever written for a passenger jet. And that is why the Dreamliner remains a marvel—not just in the air, but in the hangar.
