I think i can answer part of this but not all.
I believe RP-C8017 left BNE for the Phillipines 3-4 weeks ago.Prior to that they were leasing Asia Pacific 722F on several occasions.Whether it has gone for maintenance although the 727 in this country has only till sep 1 due to the noise scenario-WOULD it be worth it ?.Pacific Air Express have started a BNE-POM sunday flight but not sure if that is for themeselves or Heavylift.I also have heard a rumour re FAA putting the hard word on Phillipines CAB and as the aircraft are registered in the Phillipines this may have affected them ???.The CNS aircraft have not moved for years.
Does Heavy cargo know the answer.
