AD NUMBER: 2006-11-05R2
MANUFACTURER: Rolls Royce
SUBJECT: Airworthiness Directive 2006-11-05R2
SUMMARY: The FAA is
revising an existing airworthiness directive (AD) for 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 currently requires removing from service certain disc
assemblies before they reach their full published life if not
modified with anticorrosion protection.
This AD requires the same actions but relaxes the removal
compliance time for certain disc assemblies that have a record of
This AD results from the FAA allowing certain affected disc
assemblies that have a record of a detailed inspection, to remain
in service for a longer period than the previous AD allowed.
We are issuing this AD to relax the compliance time for disc
assemblies manufactured both 'before and after 1990' by providing
an option to track the disc life based on a record of a detailed
inspection rather than by its entry into service date, while
continuing to prevent corrosion-induced uncontained disc assembly
failure, resulting in damage to the airplane.
