Section.

(e) Unsafe Condition

(e) Unsafe Condition

    This AD was prompted by recent analysis of the material 
condition used in the manufacture of these parts that determined the 
high-pressure turbine (HPT) disk front cover plate may have a safe 
life below its declared safe cyclic life. The FAA is issuing this AD 
to prevent failure of the HPT disk front cover plate. The unsafe 
condition, if not addressed, could result in uncontained release of 
the HPT turbine disk front cover plate, damage to the engine, and 
damage to the airplane.

(f) Compliance

(f) Compliance

unless already done.

(g) Required Actions

(g) Required Actions

    Remove the HPT disk front cover plate, part number KH59279, from 
service prior to it reaching 1,250 engine cycles since first 
installation on an engine and replace with a part eligible for 
installation.

(h) Installation Prohibition

(h) Installation Prohibition

    Do not install any HPT disk front cover plate, part number 
KH59279, into any engine, or any engine onto any airplane, if that 
part has exceeded 1,250 engine cycles since first installation on an 
engine.
