## Abstract

This document makes corrections to Airworthiness Directive (AD) 2006-17-12. That AD applies to Rolls-Royce plc RB211 series turbofan engines. We published AD 2006-17-12 in the Federal Register on August 23, 2006 (71 FR 49339). An incorrect engine model number exists in the applicability paragraph and in the title of Table 5. Also, an incorrect serial number appears in Table 1. This document corrects these numbers. In all other respects, the original document remains the same.
