Segmentalising isn't a new idea, it happened to Singapore Airlines whilst I was there in the early to mid `90's.
The effects soon became apparent on the line, as one piece of the matrix was Engineering.
Under the new subdivisions, Engineering was shown to not be "pulling their weight", and resultantly the overall pricing structure for work done was increased.
No surprise that those in the "airline" part of the matrix now saw Engineering as an area that was costing TOO much, and that needed trimming down.
As a result, the number of MEL`s rose dramatically - to the point where one freighter was carrying in excess of 12.
It was not until that aircraft arrived in Seoul, that the Captain I was flying with discovered that 2 of the MEL's were not permissible together.
The aircraft was grounded!
Engineering will be one of the first areas to be affected under this type of segmentalising, and along with it, SAFETY.
