If it sounds too good to be true it usually is...
Looked like the exact text from SAA,s add in several aviation magazines.
I have many friends working there as CFI´s... What I hear is that you´ll be lucky to get 70h a month and a constant fight with most of the airplanes being grounded at any given time due to the old age and amount of use of the fleet.
But flying 70 is better than not flying at all so it is worthwhile to stop by and have a look and talk with the instructors while having a beer.
