The horizontal airfoil of the tail/ nose section to which the elevator/ canard is attached includes items such as spars, ribs, stringers, plates/skin, access covers, tips, etc.

A. If the wheel temperature reaches as high as 177 deg., the core of safety plug shears off and the tire slips.

B. If the wheel temperature increases to more than 177 deg., the core of the fusible plug melts and the tire deflates.

C. The core of the filter element melts once the wheel temperature is above 177 deg., causing the tire to deflate.

A. Air filter needs to be replaced on regular maintenance schedule, because it often causes low flow through the equipment cooling supply system. Quickly release the tabs on the air filter housing cover to reach the filters.

B. Low flow through the equipment cooling supply system is caused by a contaminated air filter, therefore regular replacement is necessary, release the quick release tabs on the air filter housing cover to approach to the filters.

C. A blocked air filter which causes low flow through the equipment cooling supply system needs replacement on a regular maintenance schedule. Release the quick release tabs on the air filter housing cover to reach the filters.

A. Schematic diagrams may be used to indicate "flow" and to illustrate the operation of systems such as air control, electrical, fluid power, fuel and turbosystems.

B. Principle charts can be intended to show "flow" and explain the operation of systems as well as air control, electrical, hydraulic power, fuel and turbine systems.

C. Schematic diagrams can be employed to show "flow" and to explain the operation of systems along with air control, electrical, fluid power, fuel and turbosystems.

A. Do not authorize to do the engine test.

B. The engine test will not be completed if you are not authorized.

C. If you are not approved to do this work, do not do this engine test.
