Child Care Lending Pilot Act of 2003 - Allows proceeds of loans made through the Small Business Administration (SBA) to local certified development companies for plant acquisition, construction, or expansion to be used to provide loans to small, nonprofit child care businesses, provided that: (1) the loan will be used for a sound business purpose approved by the SBA Administrator; (2) each business receiving the assistance meets eligibility requirements applicable to for-profit businesses; (3) one or more individuals have personally guaranteed the loan; and (4) the child care business has both clear and singular title to the collateral for the loan and sufficient cash flow to meet loan obligations and reasonable operating expenses. Prohibits more than seven percent of the total number of loans guaranteed in any fiscal year for local development companies from being awarded under this program. Terminates such authority at the end of FY 2006.
