**AFFECTED PARTS**

Pratt & Whitney JT8D engine series -- rotating group components.

# PURPOSE

The purpose of this notification is to advise all aircraft owners,
operators, manufacturers, maintenance organizations, and parts suppliers
and distributors regarding improper maintenance performed on Pratt &
Whitney JT8D aircraft engine components.

# BACKGROUND

Information received during a Federal Aviation Administration (FAA)
suspected unapproved parts investigation revealed that beginning in
January 2004, Aircraft Power & Service, Inc. (APS, Inc.), located at
2415 W. Arkansas, Durant, OK 74701, subcontracted nickel-cadmium plating
on JT8D engine rotating group components to a repair station that was
not approved by Pratt & Whitney, the engine manufacturer. The Pratt &
Whitney overhaul manual requires that nickel-cadmium plating be
performed by an approved vendor. APS, Inc., holds FAA Air Agency
Certificate No. AP6R434N with limited accessory, powerplant, and
non-destructive testing ratings.

# RECOMMENDATIONS

Regulations require that type-certificated products conform to their
type design and be properly maintained using current data, required
equipment, and appropriately trained personnel. Aircraft owners,
operators, manufacturers, maintenance organizations, and parts suppliers
and distributors should inspect their aircraft and/or parts inventory
for Pratt & Whitney JT8D rotating components approved for return to
service by APS, Inc. Appropriate action should be taken if any of these
components have been installed on an aircraft engine. If any existing
inventory includes these components, the FAA recommends that you
quarantine the component to prevent installation on an aircraft until a
determination can be made regarding each component's eligibility for
installation.

Below is a *partial* list of components that were approved for return to
service by APS, Inc.
