Wikipedia:Articles for deletion/Air Napier
You are confusing "I think this is an important subject" with what Wikipedia means by notability. You may think that this article should be kept, but on Wikipedia companies need extensive independent third party coverage beyond directory listings to be "notable" and clearly this subject doesn't have those references. As  says "if no reliable third-party sources can be found on a topic, then it should not have a separate article", which is the case here.  explains this in much more detail
