FAA Service Difficulty Reports: reliability by aircraft family, system and engine

Aggregates of the FAA Service Difficulty Reporting System (SDRS): 931,502 reports for 19 airliner families and 207,475 reports for 36 engine types, broken down by ATA chapter (aircraft system), year and most-reported component, plus engine variants. Browse it on FlightFinder: each family has a reliability page with the system breakdown: Boeing 737, Bombardier CRJ, Boeing 757, Boeing 767, Airbus A320, Boeing 727, Airbus A319, Airbus A321, Boeing 747, Boeing 777 and more. Engines: himaxym.com/engines. Files: aircraft_families, aircraft_family_systems, aircraft_family_system_year, aircraft_family_components, engines, engine_systems, engine_system_year, engine_components, engine_variants, engine_variant_systems (CSV), and README.md documenting every column. Read this before you use it: report counts reflect fleet size and reporting activity, not relative safety or reliability; normalise by fleet hours or cycles before comparing families. SDRs are filed by US operators and repair stations. Component names are as filed; spelling and singular/plural variants are not merged. Types rare in US service have short series (Airbus A340: 75 reports ending in 2011; A380: 24).
