DGCA safety audit slams Pawan Hans : India: India Today
Allows the centre to depart from the rules - for aircraft or pilots. I think on this occasion it relates to using military trained pilots who have not converted to civilian quals.
I liked this bit:
"After joining Pawan Hans, the pilots, who have flown single engine Chetak or Cheetah in Army, are upgraded to fly heavier machines like MI- 172. Further, these service officers may not have flown for years since they handle administrative jobs also, but are employed by the PSU and exposed to a conversion training of up to 15 hours, which is inadequate, cautioned a helicopter expert"
Though a spokesman for PHHL disagreed.
