Most users bypass the giant "Table of Contents" entirely. They go to the FIM (ATA 00). The FIM is the "search engine." Enter the flight deck warning message (e.g., "OVERHEAT-ELEC CABIN BAY").
Because there is no bleed air taken from the engines, the ECS is powered by electrically driven compressors.
The B787 was the first large commercial aircraft to utilize Lithium-Ion (Li-Ion) batteries for its APU and Main Battery systems. Following the fleet grounding in 2013, the battery containment system and charging logic were redesigned.
You can’t write about the 787 manual without mentioning the 2013 battery fires. After the grounding, Boeing completely rewrote the Chapter 24 (Battery) and Chapter 26 (Fire Protection).
Today, the manual contains an obsessive, almost paranoid procedure for the lithium-ion batteries:
The most interesting line is a warning note written in all caps:
“DO NOT ATTEMPT TO EXTINGUISH A LITHIUM BATTERY FIRE WITH HALON OR WATER. EVACUATE AND ALLOW TO BURN IN A CONTROLLED MANNER USING THE THERMAL CONTAINMENT BOX.”
That note is a direct scar from history. The manual learned from disaster.
The 787 is 50% carbon-fiber reinforced polymer. This material doesn’t crack like aluminum; it delaminates. Maintaining it is closer to fixing a broken surfboard than a metal wing.
The B787 Maintenance Manual’s Chapter 51 is legendary for its complexity. It introduces concepts that don’t exist for metal jets:
But the most interesting entry? Procedure for lightning strike inspection. Unlike metal, composite doesn’t conduct electricity. So a lightning strike won’t leave a burn mark—it will leave no external sign, but the internal fibers may be vaporized. The manual requires a tap test (listening for a dull thud) over every square foot of suspect area. It’s low-tech, human-dependent, and absolutely critical.
The "B787 maintenance manual top" is often accessed via the onboard Maintenance Laptop. The manual is fully hyperlinked. The "top" page is usually a dashboard showing the Aircraft Health Management (AHM) system. If a fault appears, the AHM links directly to the relevant chapter—bypassing the traditional index entirely.
Even veteran mechanics transitioning from the B757/B767 make errors when hitting the "top" level of the B787 manual.
Mistake #1: Assuming Paper Thinking The manual is not linear. The "top" is a digital dashboard. Do not print the entire ATA 25 (Furnishings) to find a seat actuator test—the manual updates weekly. Always check the revision date at the top of the PDF snippet.
Mistake #2: Ignoring the Safety First The B787 manual places safety warnings (WARNING, CAUTION, NOTE) before the title. On an old manual, the warning was on page 2. On the 787 digital manual, the warning pops up as a modal window. Do not click "Accept" without reading it. For example, working on the ram air turbine (RAT) : The manual's top note warns that the RAT can deploy even with the landing gear down and the hatch open. Rookies miss this because they scroll too fast.
Mistake #3: Forgetting the Boeing Service Bulletins (SB) The "standard" manual is only the baseline. The actual top of your aircraft’s configuration is changed by Service Bulletins. Many B787s have an SB that upgrades the Flight Control Software. If you are looking at the generic manual top for ATA 27 (Flight Controls), you are wrong. You need to click the "SB Incorporation" tab.
Boeing is aggressively moving toward Augmented Reality (AR) . While the "B787 maintenance manual top" is currently text and 2D diagrams, the next iteration (likely for the 787-10 and future builds) integrates 3D models.
