April 23, 2003



Teledyne Technologies Incorporated
12333 West Olympic Boulevard
Los Angeles, California  90064

Ladies and Gentlemen:

         I am Vice President and Associate General Counsel to Teledyne
Technologies Incorporated (the "Company") and I have acted as counsel for the
Company in connection with the preparation of the Registration Statement on Form
S-8 to be filed by the Company with the Securities and Exchange Commission for
the registration under the Securities Act of 1933, as amended, of an additional
200,000 shares of the Company's common stock, par value $.01 per share (the
"Shares"), which are to be issued from time to time to certain non-employee
directors of the Company in connection with the Teledyne Technologies
Incorporated 1999 Non-Employee Director Stock Compensation Plan, as amended (the
"Plan").

         I have examined the originals, certified copies or copies otherwise
identified to my satisfaction as being true copies of the Plan and such other
documents as I have deemed necessary or appropriate for purposes of this
opinion.

         Based on the foregoing, I am of the opinion that the Shares have been
duly and validly authorized and reserved for issuance, and that the Shares, when
issued under the terms of the Plan, will be legally and validly issued, fully
paid and nonassessable.

         I hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement.

                                             Very truly yours,

                                             /s/ Melanie S. Cibik

                                             Melanie S. Cibik
                                             Vice President and
                                             Associate General Counsel
                                             Teledyne Technologies Incorporated
