Dear Mr. Wilson: This responds to your December 9, 1974, question whether the 'pre-loa unit' of the Page 'Logging Simi' qualifies for an exemption from the requirements of Standard No. 121, *Air brake systems*, until September 1, 1976.; Based on the enclosed description, the 'pre-load unit' appears to be a air- braked trailer without particular brake-line or bed-height characteristics which would qualify it as a Heavy hauler trailer entitled to an exemption until September 1, 1976. Therefore, we conclude that the trailer is subject to the requirements of the standard if manufactured on or after January 1, 1975.; Yours truly, Richard B. Dyson, Acting Chief Counsel
