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

RB211-535C engine was inadvertently omitted from the AD. Also, under

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.
