Re: Offering of Shares of Series A Convertible Preferred Stock and Common Stock by Selling Stockholders

Gentlemen:

You have requested our opinion with respect to certain matters in connection with the offering by the selling stockholders named in the Registration Statement on Form S-1 of Air Industries Group, a Nevada corporation (the “Company”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the resale of 1,293,938 shares of the common stock, par value $0.001 (the “Common Shares”), of the Company (the “Registration Statement”). The Common Shares consist of 1,240,605 shares of common stock issued upon conversion of the Company’s Subordinated Convertible Notes due May 12, 2018 (the “May 2018 Notes”) and an additional 53,333 shares of common stock issuable upon conversion of the May 2018 Notes. The issuance and sale of May 2018 Notes were from the registration requirements of the Securities Act pursuant to the exemption provided by Rule 506(b) of Section 3(a)(2) of the Securities Act.

In connection with this opinion, we have examined and relied upon the Registration Statement, the Company’s Articles of Incorporation, as amended, the Company’s Amended and Restated Bylaws, each as currently in effect, the May 2018 Notes, and the originals, or copies certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below.
