Lycoming HIO-360 series

390 aircraft on the U.S. register carry a Lycoming HIO-360 series engine, rated at about 205 horsepower. The Schweizer 269 300 series helicopters is the model most often fitted with it (90 aircraft). The aircraft carrying it were built between 1959 and 2016.

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 HIO-360 series (2 codes). FAA spellings: HIO-360 SER · HI0-360 SER.

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.
