error resulted in an incorrect part number for the replacement supports
for the engine bleed air duct. This AD is applicable to certain EMBRAER
Model EMB-135 and -145 series airplanes. This AD requires replacing the
four GAMAH clamp/sleeve joints on an engine bleed air duct with new
threaded coupling assemblies; for certain airplanes, this AD also
requires replacing the two supports for the engine bleed air duct with
two new supports.

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 2003-12-04,
amendment 39-13189, applicable to certain EMBRAER Model EMB-135 and -
145 series airplanes, was published in the Federal Register on June 12,

sleeve joints on an engine bleed air duct with new threaded coupling
assemblies; for certain airplanes, that AD also requires replacing the
two supports for the engine bleed air duct with two new supports.
As published, paragraph (a)(2) of the AD cites an incorrect part
number (145-35923-007) for the replacement supports for the engine
bleed air duct. The correct part number is 145-35923-015.
Since no other part of the regulatory information has been changed,
the final rule is not being republished in the Federal Register.
The effective date of this AD remains July 17, 2003.
