The horizontal stabilizer is primarily of all-metal construction, consisting of ribs and spars covered with skin. A formed metal leading edge is riveted to the assembly to complete the structure. The elevator trim tab actuator is contained within the horizontal stabilizer. The underside of the stabilizer contains a covered opening which provides access to the actuator. Hinges are located on the rear spar assembly to support the elevators.

VACUUM SYSTEM

By -
TTP B1-L3 ATA37 Cessna 172 B2-L2   V acuum system has a filter, vacuum gage, vacuum instruments, regulator valve, vacuum manifold,  low vacuum annunciator switches, engine-driven vacuum pumps and related plumbing.   With   Garmin G1000, the source of vacuum air is in the cabin and is pulled through the  system by the engine-driven vacuum pumps. This air goes through the gyro filter at the cabin inlet source  before it goes through the vacuum gage and gyro instruments. The vacuum is controlled by the regulator  valve. The regulator valve is on the aft side of the firewall. The vacuum air is then pulled through the  vacuum manifold and past the low vacuum annunciator switches and then into the vacuum pumps. Without Garmin G1000, vacuum pressure is measured by the low vacuum annunciator   switches in the engine compartment. The vacuum gage in the instrument panel shows the vacuum  pressure. Vacuum gag e gives a direct indication of the
