the comments received.
Background
This memorandum clarifies FAA
guidance on the design, certification,
and continued airworthiness of control
surfaces that rely on retention of
restraint stiffness for flutter prevention.
These control surfaces typically do not
have added mass balance, but there are
some that are partially mass balanced
for which the guidelines would also
apply. This memorandum provides
acceptable means of establishing and
certifying freeplay limits and inspection

procedures, provides guidance for
managing freeplay over the airplane
service life, and provides a means of
finding compliance for control system
designs whose failure can result in a
nonlinear aeroelastic configuration and
limit cycle oscillation (LCO). This
memorandum provides interim
guidelines and standardized methods of
compliance that address the
inadequacies of current guidance, until
the FAA revises the applicable guidance
contained in AC 25.629–1A.

Availability of a Draft FONSI/FONPA
Department of Transportation,
Maritime Administration.
ACTION: Notice of the Availability of a
draft Finding of No Significant Impact/
Finding of No Practicable Alternative.
AGENCY:
SUMMARY: The purpose of this Notice is
to make available to the public the draft
Finding of No Significant Impact/
Finding of No Practicable Alternative
(FONSI/FONPA) for the Port of
Anchorage Intermodal Expansion, North
End Runway Material Extraction and
Transport Project (Project).
A draft Environmental Assessment
(EA), dated March 2006, was prepared
that analyzed the potential impacts on
the human and natural environment
associated with the proposed material
extraction activities at the North End
Borrow Site and potential transportation
corridors located on Elmendorf Air
Force Base (EAFB). A final EA and a
final FONSI/FONPA will be published
once comments have been properly
addressed. This environmental
documentation supports the proposed
expansion of the Port of Anchorage
(POA), which includes a variety of
activities to enhance the transportation
of goods and people within the State of
Alaska.
DATES: Comments on this draft FONSI/
FONPA must be received by May 24,
2006.
You may submit comments
[identified by DOT DMS Docket Number
MARAD–2006–24149] by any of the
following methods:
