Lycoming O-360-A1A

600 aircraft on the U.S. register carry a Lycoming O-360-A1A engine, rated at about 180 horsepower. The Cessna 170 is the model most often fitted with it (8 aircraft). The aircraft carrying it were built between 1946 and 2026.

The FAA records engines by code, usually at the level of a series ("O-320 series") rather than the exact variant; this page gathers every FAA code that reads as Lycoming O-360-A1A. FAA spelling: O-360-A1A.

Sources: the FAA's type certificate data sheets, airworthiness directives, supplemental type certificates, special conditions and special airworthiness information bulletins (Dynamic Regulatory System), and the FAA's service difficulty reports. A failure report is what an operator or repair station chose to file; the counts show reporting as much as reliability, and larger and commercial fleets report more. How the systems are grouped.
