212, Airworthiness is essentially either:
1. Complaince with the Manufacturers Guidelines and Adherence to the Limitations in the Rotorcraft Flight Manual, OR
2. A limited approval to not be compliant granted by the Competent Authority following a submission and justification.
The business is risk mitigation. It may be deemed acceptable to RTB the AC without PAX. As crew we always have the right to decline the invitation.
