Ladies and Gentlemen:

We have acted as counsel to Ducommun Incorporated, a Delaware corporation (the “Company”), in connection with the preparation of the Company’s registration statement on Form S-3 to be filed with the Securities and Exchange Commission (the “Commission”) on or about the date hereof (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Securities Act”).

The Registration Statement relates to the proposed offer, issuance and sale from time to time on a delayed or continuous basis pursuant to Rule 415 under the Securities Act, as set forth in the Registration Statement, the prospectus contained therein and any supplement to the prospectus, of one or more series of the following securities of the Company:

(a) shares of common stock of the Company, par value $0.01 per share (the “Common Stock”), to be offered, issued and sold by the Company;

(b) shares of preferred stock of the Company, par value $0.01 per share (the “Preferred Stock”);

(c) depositary shares representing a fractional interest in a share of Preferred Stock of the Company (the “Depositary Shares”);

(d) debt securities of the Company, in one or more series (the “Debt Securities”), which will be issued under an Indenture, a form of which is filed as an exhibit to the Registration Statement (as amended or supplemented, the “Indenture”), to be entered into by and between the Company and the trustee named therein (the “Trustee”);

(e) warrants to purchase the Common Stock, the Preferred Stock, the Depositary Shares, the Debt Securities or units of two or more of these types of securities (the “Warrants”), which will be issued pursuant to a warrant agreement, which will be filed at a later date by amendment or as an exhibit to a document incorporated by reference into the Registration Statement, to be entered into by and between the Company and a bank or trust company as warrant agent;

(g) stock purchase units consisting of a Stock Purchase Contract and either the Preferred Stock, the Depositary Shares, the Debt Securities, or other securities, or any combination of the foregoing securities (the “Stock Purchase Units”); and
