Hi, Yes, if it is not coming up in disk utilities, it does sound like the SSD has failed unfortunately. Very strange to happen on install, but it is not unheard of (Macbook Air SSDs are the most common to fail). This is a very easy repair though (remove bottom cover, disconnect battery, remove SSD and put new one in), so I would recommend doing it yourself, since the SSDs are expensive. Once installed, you just need to format it correctly in disk utilities, then you will be able to install the OS.
