Airplanes with engine modifications (and possibly increased gross weights) will have additional information in the Supplemental Airplane Flight Manual in Section 9. Refer to the official aircraft documents for ALL information. ATP Cessna 172 aircraft models include R / S models ( “Late Model”) and L through N models (“Early Model”). Over 90% of ATP's Cessna 172 fleet are Late Model. R-model Cessnas were introduced in 1996, and were the first to come factory- equipped with fuel-injected engines. Starting procedures are substantially different between the earlier models with carbureted engines and the later models with injected engines. Review the engine start procedures by referencing the latest ATP 172 checklist for the 172 model you will be flying. Model Number Year of Production 172 L 1971–72 172 M 1973–76 EARLY MODELS 172 N 1977–80 172 R 1996–2009 LATE 172 S 1998–Present MODELS Early & Late Model Overview • 1 NOTE: R-model 172s were originally delivered with 160-horsepower engines. However, ATP's R-model aircraft have received a propeller modification that provides for an increase to 180 horsepower (matching the S model), which in turn increases fuel burn and maximum allowable takeoff weight. ATP's early-model Cessna 172s have different combinations of engine horsepower and usable fuel. Some aircraft carry only 38 gallons of useable fuel, and have been modified with a 180-horsepower engine. These airplanes have an increased fuel burn and a significantly reduced endurance of approximately 3 hours in the training environment – even with full tanks. Calculate your fuel requirements carefully. Reference the aircraft manuals and placards for the appropriate information. Airworthiness and registration certificates, which list the aircraft model, can be found on the forward lower left interior cabin wall. Weight and balance information can be found in the blue aircraft maintenance logbook, as well as Section 6 of the POH. 2 • Early & Late Model Overview SECTION 2 Aircraft Systems Late Model (R&S) System descriptions are given first for Late Model aircraft, and then differences only for Early Models. Engine The 172 R and S models are equipped with a Lycoming, 4-cylinder, normally- aspirated, fuel-injected, 360 cubic inch, horizontally-opposed, air-cooled, direct-drive IO-360-L2A engine. This engine is rated at 180 HP at 2700 RPM as factory-delivered on S-models and as upgraded on R-models. (See note on page 2 regarding engine modifications.) Ignition is provided by 2 magnetos on the back of the engine which provide power to 8 spark plugs (2 per cylinder, for redundancy and more complete combustion). The engine has an 8-quart oil sump. ATP's minimum oil quantity for takeoff is 6.5 quarts. Propeller The engine drives a McCauley, 76 inch, two-blade, all-metal, fixed-pitch propeller. Vacuum System On aircraft with conventional flight instruments, two engine-driven vacuum pumps are located on the back of the engine, providing vacuum to the attitude and heading gyros. These have a normal operating range of 4.5-5.5 inches of mercury. Failure of a vacuum pump is indicated by an annunciator panel light. In most circumstances, failure of one pump alone will not cause the loss of any instruments, because the remaining pump should handle the entire vacuum demand. On aircraft with the G1000 glass cockpit, a single engine-driven vacuum pump provides vacuum to the
