Lycoming O-320-D1A

116 aircraft on the U.S. register carry a Lycoming O-320-D1A engine, rated at about 160 horsepower. The Gyroflug SC 01 is the model most often fitted with it (4 aircraft). The aircraft carrying it were built between 1987 and 2025.

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-320-D1A. FAA spelling: O-320-D1A.

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.
