The FAA has issued 86 airworthiness directives (orders that owners must comply with) that name this model, most of them about engine. Operators and repair shops have filed 7,541 failure reports with the FAA since 2006, 3,227 of them in the last ten years: about 658.6 a year for every 100 aircraft on the register; the system most often named is airframe structure. 78 approved modifications exist for it, the most by Safran Cabin INC..

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.
