Dont know what you based your post on balut but atleast i have seen with my eyes that CA has 2 172s flying. They also additionally rent 2 152s from Omni...well sometimes 8842 (C172) also....you just dont see them anymore at Omni field coz they have moved out to the Main!
(Something in my opinion they should have done a long time ago...considering that they fly IFR quite often...well better late than never
Its much easier to fly night and IFR from the main + the flt ops facilites are a lot better now!)
Whats not flying is the Alpha...thats why you see CA renting the 152s...as i always have maintained...the Alphas were a mistake...lack of spares/trained technicians/instructors in the Philippines for that model...but otherwise that aircraft was a nice lil plane to fly! (much better than the cessna...stick forces were pretty light)
