Ladies and Gentlemen:

We have acted as special counsel for Loar Holdings Inc., a Delaware corporation (the “Company”) in connection with the Company’s Registration Statement on Form S-1 (Registration No. 333-278475) (the “Registration Statement”) initially filed with the United States Securities and Exchange Commission (the “Commission”) on April 2, 2024, together with all exhibits and as subsequently amended, pursuant to the Securities Act of 1933, as amended (the “Securities Act”), relating to the offer and sale by the Company of 12,650,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), including 11,000,000 shares of Common Stock to be sold by the Company (the “Firm Shares”) and up to 1,650,000 shares of Common Stock to be sold by the Company to cover the underwriters’ option to purchase additional shares from the Company (the “Option Shares” and, together with the Firm Shares, the “Securities”).

In connection with our acting as hereinabove described, we have examined and relied solely on originals or copies, certified or otherwise identified to our satisfaction as being true copies, of all such records of the Company, all such agreements, certificates of officers of the Company and others, and such other documents, certificates and corporate or other records as we have deemed necessary as a basis for the opinion expressed in this letter, including, without limitation, the following:

(c) the Registration Statement and all exhibits thereto.

As to facts material to the opinion expressed in this letter, we have relied on statements and certificates of officers and of state authorities and on the representations, warranties and statements contained in the Transaction Document.

In rendering the opinion expressed in this letter, we have assumed, with your permission and without any investigation on our part, that:
