AIRCRAFT STRUCTURE
In the J230 due to it’s monocoque construction the majority of the structure is primary.
The components of the aircraft which are secondary structure can be identified by the fact
that they are designed as fairings and are generally removable. Examples of secondary
structure are the engine cowls, speed fairings, ventral fin and wheel spats.
