PRODUCT: RRD BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines.
SUBJECT: Airworthiness Directive 2009-07-01 R1
ACTION: Final Rule; rescission.
SUMMARY: The existing AD resulted from the need to reduce the published life limits of high-pressure (HP) turbine stage 1 discs, part numbers (P/Ns) BRH20130 and BRH20131, and HP turbine stage 2 discs, P/Ns BRH19423 and BRH19427.

DATES: This AD is effective August 6, 2012.
