Cessna 172R

TTP B1-L3 ATA12 Cessna 172 B2-L1                 Fuel Tanks. :  Each wing contains an integral fuel bay, located between the front and rear spars, extending from WS  31.38 to WS 65.125. Fuel bays should be filled immediately after each flight to lessen condensation  in the tanks and lines. A fuel filler cap is located on top of each wing and provides a fueling/defueling  point for each fuel bay.               Fuel Drains. "  Fuel drains are located at various places on the underside of each integral fuel bay and throughout  the fuel system. These drains are utilized to collect fuel samples for analysis. This sampling is  accomplished by placing the fuel sample cup up to the drain valve, and depressing the valve with rod  protruding from the cup. Safety Precaution: Ground airplane first. Ground vehicle  to the s...

  Directional Gyro Operational Check  NOTE:  The permitted limit for gyro drift on the ground or in flight is 4 degrees from a    fixed heading, during a 10-minute period. (1) Start the airplane engine. (2) Make sure that the vacuum system operates correctly. (a) The vacuum gage must show between 4.5 and 5.5 inches Hg. (3) Let the directional gyro become stable for at least 3 minutes. (4) If the directional gyro dial starts to turn, let the gyro become stable and then push the gyro- caging knob. If the gyro dial continues to turn, repair the system and/or replace the gyro. NOTE:  It is usual for the directional gyro dial to turn when the gyro becomes stable. This is not  a cause for removal. (5) Point the airplane's heading to the north. (6) Set the directional gyro to the north. (7) Make sure that the DG  dial drift is not more than 4 degrees in a 10-minute  period. (8) Do steps 5 through 7 again for each cardinal ...

    PTP Cessna 172 B1 LOC FOT SGH R/I MEL TS B2 LOC FOT SGH R/I MEL TS                        This fuel sampling procedure is required to be carried out before preflight. With the airplane in the normal ground attitude and starting at the highest drain location, check all drain locations for contaminants before every flight, whether or not refueling has occurred. Have fuel sample disposal provisions, proper lighting, and a small ladder at your disposal to properly check for fuel tank system contamination. Drain at least one cup of fuel (using a clear sampler cup) from each drain location. Drain the fuel strainer as required to completely flush its contents in each of the fuel selector positions. Check for water, clarity, cloudiness, haze, proper fuel type/grade (i.e.; 100LL is light blue in tint, jet fuel is clear or ye...

                long-term preservation of engines can result in trapping large amounts of oil in the combustion chambers of one or more cylinders. For this reason, engines should not be rotated until all of the preservative oil is drained away. Failure to do so can result in damage to the piston, connecting rod, and crankshaft of the flooded cylinder    To return the aircraft to service - remove seals, tape, and desiccant bags. Use a solvent to remove tape residue. Remove spark plugs or dehydrator plugs. With the magnetos off, rotate the propeller by hand through sufficient rotations to remove excess preservative oil from the cylinders. Drain the remaining preservative through the sump. Most engines are equipped with a quick-drain oil fitting on one side of the oil sump and a standard AN plug on the other. Remove both in order to drain as much of the preservative oil from the sump as possible. Uninstalled engines should be hoist...

TTP B1-L3 ATA71 Cessna 172 B2-L1 Lycoming's preservation procedure : Drain the lubricating oil from the sump or system and replace with a preservative oil mixture. This preservation mixture consists of one part by volume MIL-C-6529C Type I concentrated preservative compound added to three parts by volume of MIL-L-6082C (SAE J1966), Grade 1100, mineral aircraft engine oil or oil conforming to MIL-C-6529C Type II. Follow carefully the manufacturer's instructions before use. An alternative method is the use of Cortec VC1-326 preservative concentrate added to the original oil at a ratio of 1 part VC1-326 to 10 parts of oil. Operate the engine until normal temperatures are obtained. Do not stop engine until oil temperature has reached 180°F. If weather conditions are below freezing, oil temperature should reach at least 165°F before shut down. Remove sufficient cowling to gain access to the top spark plugs and remove them. Through the...
