SUMMARY: This document makes a correction to Airworthiness Directive 
(AD) 2004-01-20, which is applicable to Rolls-Royce plc (RR) RB211-22B 
series, RB211-524B, -524C2, -524D4, -524G2, -524G3, and -524H series, 
and RB211-535C and -535E series turbofan engines with high pressure 
compressor (HPC) stage 3 disc assemblies, part numbers (P/Ns) LK46210, 
LK58278, LK67634, LK76036, UL11706, UL15358, UL22577, UL22578, and 
UL24738 installed. That AD was published in the Federal Register on 
January 20, 2004 (69 FR 2661). The compliance information for the 
RB211-535C engine was inadvertently omitted from the AD. Also, under 
Related Information, the referenced service bulletin is not the latest 
revision. This document adds the omitted information and corrects the 
service bulletin reference. In all other respects, the original 
document remains the same.

Effective Date: Effective January 20, 2004.
