**AFFECTED AIRCRAFT**

All aircraft.

## PURPOSE

The purpose of this notification is to advise all aircraft owners,
operators, maintenance organizations, manufacturers, and parts suppliers
and distributors regarding raw metal sold with altered material
certification.

**BACKGROUND**

Information received during a Federal Aviation Administration (FAA)
suspected unapproved parts investigation revealed that M&M International
Aerospace Metals, Inc. (M&M), located at 1382 West McNab Road, Fort
Lauderdale, FL 33309, may have knowingly sold raw metal that was offered
as meeting the applicable Mil Spec but did not. M&M sold the raw metal
to various distributors, type certificate holders, production approval
holders, experimental aircraft distributors, as well as a variety of
military and commercial applications.

Evidence indicates that M&M may have deliberately altered material
certifications in order to satisfy customer requirements when they knew
that the material did not meet the full requirements. The following
changes were found:

-   Specification numbers were added.

-   Quantities were changed.

-   Heat-treat certifications were altered.

-   Chemical analysis requirements were added.

-   Hardness test results were changed.

-   Names of required mills were changed to match purchase order
    requirements.

The Offices of the Inspector General for the Department of
Transportation, Department of Defense, Department of Energy (DOE),
National Aeronautics and Space Administration, and the FAA conducted an
investigation. DOE and FAA performed tests on the materials and examined
purchase orders; these tests revealed nonconformance with the purchase
orders.

**RECOMMENDATIONS**

Regulations require that type-certificated products conform to their
type design. Aircraft owners, operators, maintenance organizations,
manufacturers, and parts suppliers and distributors should inspect their
records for raw metal purchased from M&M and examine those records for
alterations. If material certifications are suspected of being altered,
it is recommended that the original certificate supplier be contacted
for a copy of the original certification, or independent tests be run
for the original purchase order requirements. If the material is
determined to be nonconforming, the stock \-- or parts made from the
stock \-- should undergo an engineering analysis that is based on the
material's location or use in its proposed application.

**FURTHER INFORMATION**

Further information concerning this investigation and guidance regarding
the above-referenced raw material can be obtained from the FAA
Manufacturing Inspection District Office (MIDO) given below. The FAA
would appreciate any information concerning the discovery of this
material from any source, the means used to identify the source, any
action allowing the material to remain in service, and any action taken
to remove the material from service.
