Denial of Petition Regarding 49 CFR Part 572, Subpart O, Hybrid III Fifth Percentile Small Adult Female Crash Test Dummy

This document denies a petition submitted by First Technology Safety Systems (FTSS) on December 30, 2002. The petition asked the agency to revise drawing dimensions for the Hybrid III 5th Female (HIII-5F) chest jacket to reflect the physical part manufactured by FTSS. FTSS did not provide any data showing that these slight dimensional differences would affect the dummy's performance, nor did FTSS provide any justification for changing NHTSA's drawing specifications in CFR Section 49, Part 572 Subpart O drawings to FTSS's suggested specifications. Revising the Agency's drawing specifications to FTSS's suggested specifications appears to provide little to no benefit. Furthermore, FTSS did not claim they are unable to meet NHTSA's current drawing specifications. Accordingly, the agency finds no basis to revise the drawings as requested by FTSS.
