  <link>http://thefederalregister.com/d.p/2003-12-18-03-31060</link>
  <description><![CDATA[ This amendment supersedes an existing airworthiness directive
(AD), applicable to certain Airbus Model A319 and A320 series
airplanes, that currently requires revising the airplane flight manual
to specify procedures for landing under certain conditions of gusty
winds and turbulence. This amendment requires replacement of both
Elevator and Aileron Computers (ELACs) having L80 standards with new
ELACs having L81 standards, which terminates the requirements of the
existing AD. The actions specified by this AD are intended to prevent
activation of the high angleofattack protection during final approach
for landing, which could result in loss of ability to flare properly
during landings. This action is intended to address the identified
unsafe condition.

  <description><![CDATA[ This amendment supersedes an existing airworthiness directive
(AD), applicable to certain Bombardier DHC8102, 103, 106, 201,  202, 301, 311, and 315 airplanes, that currently requires<br/>
inspections to detect breakage in the struts of the rear mount strut
assemblies on the left and right engine nacelles, and replacement of
any broken struts. The existing AD also requires eventual replacement
of all currently installed struts with new and/or reworked struts, as
terminating action for the inspections. The amendment requires new
repetitive inspections of the strut assemblies for cracking of struts
replaced per the existing AD, and replacement of any cracked strut with
a new, machined strut. The amendment also changes the applicability of
the existing AD by adding certain airplanes and removing certain other
airplanes, and includes an optional terminating action for the
repetitive inspections. The actions specified by this AD are intended
to prevent failure of the engine rear mount struts, which could result
in red<script type="text/javascript">

  <link>http://thefederalregister.com/d.p/2003-12-18-03-31179</link>
  <description><![CDATA[ This document proposes the supersedure of an existing
airworthiness directive (AD), applicable to certain Airbus Model A310
series airplanes, that requires repetitive inspections of the fuselage
skin to detect corrosion or fatigue cracking around and under the
chafing plates of the wing root; and corrective actions, if necessary.
That AD also provides an optional terminating action for the repetitive
inspections. This action would reinstate repetitive inspections in
certain areas where corrosion was detected and reworked as required by
the existing AD. The actions specified by the proposed AD are intended
to detect and correct fatigue cracks and corrosion around and under the
chafing plates of the wing root, which could result in reduced
structural integrity of the airplane. This action is intended to
address the identified unsafe condition.

  <link>http://thefederalregister.com/d.p/2003-12-18-03-31182</link>
  <description><![CDATA[ This document proposes the adoption of a new airworthiness
directive (AD) that is applicable to certain Airbus Model A300 B4600
and A300 C4600 series airplanes. This proposal would require a one
time inspection to detect damage of the pump diffuser guide slots
(bayonet) of the center tank fuel pumps, the pump diffuser housings,
and the pump canisters; repetitive inspections to detect damage of the
fuel pumps and the fuel pump canisters; and corrective action, if
necessary. This action is necessary to detect and correct damage of the
center tank fuel pumps and fuel pump canisters, which could result in
separation of a pump from its electrical motor housing, loss of flame
trap capability, and a possible fuel ignition source in the center fuel
tank. This action is intended to address the identified unsafe
condition.

  <description><![CDATA[ This document proposes the supersedure of an existing
airworthiness directive (AD), applicable to certain Airbus Model A300 series airplanes, that currently requires either a onetime<br/> [[Page 70465]]<br/>
ultrasonic inspection, or repetitive visual inspections and eventual
ultrasonic inspection, to detect cracking of the longitudinal skin
splice above the midpassenger door panels, and corrective actions if
necessary. This action would require repetitive ultrasonic inspections
to detect cracking of certain skin lap joints in additional areas of
the fuselage and repair if necessary. This action also would expand the
applicability of the existing AD to include additional airplanes. The
actions specified by the proposed AD are intended to detect and correct
cracking of certain skin lap joints, which could result in reduced
structural integrity and decompression of the airplane. This action is
intended to address the identified unsafe condition.

  <description><![CDATA[ This document proposes the adoption of a new airworthiness
directive (AD) that is applicable to certain Boeing Model 707 and 720
series airplanes. This proposal would require repetitive inspections of
the upper and lower barrel nuts and bolts that retain the aft trunnion
support fitting of each main landing gear for corrosion, cracks, and
loose or missing nuts and bolts; torque checks of the upper and lower
bolts to verify the torque is within a specified range; and corrective
actions, if necessary. This action is necessary to detect and correct
cracking and/or loss of the barrel nuts and bolts that retain the aft
trunnion support fitting, which could result in the collapse of the
main landing gear upon landing. This action is intended to address the
identified unsafe condition.

  <description><![CDATA[ This document proposes the adoption of a new airworthiness
directive (AD) that is applicable to all Bombardier Model DHC8101,  102, 103, 106, 201, 202, 301, 311, and 315 airplanes. This<br/>
proposal would require a detailed inspection of the wing leading edge
deicer boots to determine if they comply with the patch size and/or
patch number limits in the critical zone as defined in the Aircraft
Maintenance Manual; and corrective action, if necessary. This action is
necessary to prevent reduced aerodynamic smoothness of the wing leading
edge deicer boots and possible reduced stall margin, which could
result in a significant increase in stall speeds, leading to a possible
stall prior to activation of the stall warning. This action is intended
to address the identified unsafe condition.

  <link>http://thefederalregister.com/d.p/2003-12-18-03-30606</link>
  <description><![CDATA[ FRA is issuing rules to require that a locomotive horn be
sounded while a train is approaching and entering a public highwayrail
crossing. The rules also provide for an exception to the above
requirement in circumstances in which there is not a significant risk
of loss of life or serious personal injury, use of the locomotive horn
is impractical, or safety measures fully compensate for the absence of
the warning provided by the horn. This rule is required by law.
