: Detailed breakdowns of the "more-electric" systems.
With systems running at 235 VAC and +/- 270 VDC, following the AMM lockout/tagout and de-energization steps is vital to technician safety.

Traditionally, maintenance focused heavily on pneumatic ducts (hot air from engines). The 787 eliminates engine bleed air. Therefore, the "top" sections for air conditioning (ATA 21) and anti-icing now rely on electrical compressors and engine-driven generators. If you search the B787 manual for a "bleed air duct leak," you will find a redirect to "no procedural data defined." : Detailed breakdowns of the "more-electric" systems
The manual doesn’t describe how to test—it describes which button to push on a screen. The intelligence moved from the mechanic’s brain to the airplane’s software. This terrified old-timers... until they realized they no longer needed to memorize 10,000 fault trees.
However, I can create a discussing the "Top" maintenance concepts, unique challenges, and critical systems associated with the Boeing 787 Dreamliner. This paper focuses on the transition from hydraulic to electrical systems and the specific maintenance philosophies required for this next-generation aircraft.

: Provides part numbers and locations for hardware, such as the redesigned forward engine mount barrel nuts [8, 11]. For professional access, technicians typically use Boeing's MyBoeingFleet
The B787 is a "Smart Aircraft." The maintenance philosophy shifts from Reactive to Predictive .
