The Cessna 172 family includes multiple model variants produced across several generations. The 172, 172A through 172P, 172R and 172S designations correspond to different production periods and aircraft configurations, and their weight and balance applicability can differ.
Cessna 172 overview
The Cessna 172 is one of the best-known four-seat single-engine aircraft families in general aviation. The family has evolved through numerous model designations, each tied to a particular production period and configuration.
For aircraft identification, the suffix matters. A Cessna 172M, for example, is not simply another name for a 172N or 172P. Model designation, serial number and aircraft records should be checked before selecting performance, loading or weight and balance information.
Cessna 172 models and production years
Select Specs & details to view available engine, dimensions, weights, fuel capacity and other model-specific aircraft information. Use W&B Calculator to open the weight and balance tool for that model.
How to identify the correct 172 model
Start with the exact aircraft model shown in the aircraft records, POH or AFM. The production-year table above can then be used as a cross-check.
Examples include the 172M for model years 1973–1976, the 172N for 1977–1980, the 172P for 1981–1986, the restarted-production 172R beginning in 1997, and the 172S beginning in 1998.
Production year alone is not sufficient for final aircraft identification. Serial-number applicability and the approved documentation for the individual airplane remain authoritative.
172 model differences
Model variants within the same aircraft family can differ in engine installation, maximum weight, fuel system, loading stations, baggage limits and center-of-gravity envelope. Check the limits and loading data for the exact aircraft model and configuration.
Cessna 172 weight and balance
Weight and balance data should be matched to the exact Cessna 172 model. Closely related 172 variants can use different maximum weights, loading stations, fuel arrangements and center-of-gravity limits.
WBcalc therefore provides separate model-specific calculators rather than treating every Cessna 172 as interchangeable. Use the calculator link beside the exact model in the table above.
The aircraft's current basic empty weight, moment or arm must always come from the current weight and balance record for that individual aircraft. A reference value from another airplane should never be substituted.
Frequently asked questions
What years was the Cessna 172M produced?
The Cessna 172M covers model years 1973 through 1976.
What years was the Cessna 172N produced?
The Cessna 172N covers model years 1977 through 1980.
What years was the Cessna 172P produced?
The Cessna 172P covers model years 1981 through 1986.
Is a Cessna 172M weight and balance calculator the same as a 172N calculator?
They should not automatically be treated as interchangeable. Weight limits, CG envelopes, loading stations and other applicability details must be verified for the exact aircraft model and configuration.
How do I identify which Cessna 172 model I have?
Use the exact model designation and serial-number information in the aircraft records, POH or AFM. Production years can help narrow the model but should not be used as the sole identification method.
