Which statement is true about ABAs on an 800 aircraft?

• A. A, B, and C each have 6 ABAs, while D has 6 ABAs.
• B. A, B, and C each have 8 ABAs, while D has 10 ABAs.
• C. A, B, and C each have 6 ABAs, while D has 10 ABAs.
• D. A has 6 ABAs, B has 6 ABAs, C has 8 ABAs, D has 10 ABAs.

Answer: (C)

ABAs are counted by zones on the 800 to reflect how many assemblies support the equipment installed in each area. The true distribution shows three zones with six ABAs each, while the remaining zone has ten ABAs. This pattern fits the aircraft’s layout where one zone carries more equipment—such as major racks or power/avionics modules—requiring more ABAs, while the other zones have a similar, smaller load. Other distributions would conflict with how the equipment is actually arranged on the aircraft, either implying equal loads across zones or shifting the larger count to a zone that doesn’t carry as much hardware.
