What kind of aircraft is this?
The Boeing 787 Dreamliner is a twin-engine, twin-aisle long-haul jet with a largely carbon-composite structure, in service since 2011.
In plain terms, it's a jet (turbofan) multi-engine airplane. Certification: Type certificated (factory design approved by the FAA).
There are 118 aircraft of this exact model variant on the US register, and about 214 Boeing aircraft with closely related model designations, out of 317,717 registered aircraft in total. That's a well-established type that mechanics, pilots and regulators know very well.
An aircraft's age on its own says little about how safe it is: airliners are maintained on strict, regulator-approved schedules, and inspections become more detailed as aircraft get older. More about the Boeing 787 Dreamliner →
