Narrative:

My crew and I were called out on an emergency lifeguard/medivac flight to transport an organ and 4 surgeons on short notice on a life saving mission. The copilot copied a clearance while I completed documentation. When I asked to read back to me our clearance; my co pilot responded we received the pomona 7 departure and to climb to 14;000 feet. The ont departure already has a climb over bucck intersection to 14;000. Since it was late and late evening traffic is reduced; I incorrectly assumed he may be correct. I inquired if there were any crossing restrictions and he responded no. This was an incorrect interpretation not apathetic or careless in nature in any way. My copilot did not hear the clearance correctly and was not familiar with the area; which contributed to the conflict with the new 'climb via' procedures. I also sincerely believe my copilot misinterpreted the term 'climb via; except climb to 14;000' as a general climb term to climb along and the phrase 'except' was a cancellation of any other climb restrictions. My survival instinct to climb quickly over fast rising terrain on a northwest bound heading in the darkness may have been a factor. There is also the confusion since we were not on a published route yet that ATC would provide any vector separation until we were on a published route. Of important note; my copilot also pointed out when we checked in with departure; he had contacted and communicated with ATC; 'climbing to 14;000 feet'. No ATC correction to our climbing to 14;000 feet was made by ATC. This to us meant we were doing the right thing. There was no traffic advisory (TA) or resolution advisory (RA) conflict audio or video at all. We received no TCAS warning either.

Narrative: My crew and I were called out on an emergency LIFEGUARD/MEDIVAC flight to transport an organ and 4 surgeons on short notice on a life saving mission. The copilot copied a clearance while I completed documentation. When I asked to read back to me our clearance; my co pilot responded we received the Pomona 7 departure and to climb to 14;000 feet. The ONT departure already has a climb over BUCCK intersection to 14;000. Since it was late and late evening traffic is reduced; I incorrectly assumed he may be correct. I inquired if there were any crossing restrictions and he responded no. This was an incorrect interpretation not apathetic or careless in nature in any way. My copilot did not hear the clearance correctly and was not familiar with the area; which contributed to the conflict with the new 'CLIMB VIA' procedures. I also sincerely believe my copilot misinterpreted the term 'CLIMB VIA; EXCEPT CLIMB TO 14;000' as a general climb term to climb along and the phrase 'EXCEPT' was a cancellation of any other climb restrictions. My survival instinct to climb quickly over fast rising terrain on a northwest bound heading in the darkness may have been a factor. There is also the confusion since we were not on a published route yet that ATC would provide any vector separation until we were on a published route. Of important note; my copilot also pointed out when we checked in with departure; he had contacted and communicated with ATC; 'CLIMBING TO 14;000 feet'. No ATC correction to our climbing to 14;000 feet was made by ATC. This to us meant we were doing the right thing. There was no Traffic Advisory (TA) or Resolution Advisory (RA) conflict audio or video at all. We received NO TCAS warning either.
