The Maintenance & Engineering Organization
There are 3 basic concepts for mid-sized
airline underlying the structure;
Span of control
1. Concept of Span of control (หลัก
ขนาดของการควบคุม)
2. Grouping of similar functions
(พิจารณาตามหน ้าที)่
3. Separation of production and
oversight functions; from the
oversight functions of inspection,
control and , monitoring
(Quality assurance, Quality control,
Reliability and safety)
