No standards set in EG for Helicopter Ops, CHC do in house audits, the SACAA audit is a joke on ZS registered aircraft, the Belguim goes up to EG for a whoring vacation, the oil auditors keep them honest.

Guess what no SOP's. Evidently they also operate an Augusta 109, anybody know what their registration is or possibly paste a photo on it.
