     (3)  Acrylic windshields on aircraft have become pitted,
scratched, and abraded as a result of blowing sand and dust.
The conditions are such that windshields are becoming
unserviceable.  AVSCO~ anticipated the abrasion and erosion of
acrylic windshields.on aircraft involved in DESERT SHIELD and
identified a hard coating for AH-64%UH-60/OH-58/AH-l.   The
approach for application is to take parts from stock, ship to
contractors for coating, then ship to Saudi Arabia.    Hardened
windshields will be changed out by attrition.    The application
is not a unit/AvuM/AvIM function.

     (4)  Aircraft engine support for SWA.   Aircraft engines in
SWA are experiencing power loss and premature failure because
of the harsh environment associated with high temperatures ana
ingestion of sand and dust.   AVSCOM has developed an agg:ress~.
prevention and repair strategy.   Prevention initiat1v0~s 1flO~(:
improved particle separators for the Ch.-47D, UH-l, and Ar~-l;
increased water flush and cool down procedures; and
modification of the in-flight engine Health Indicator Test
(HIT) check.   Repair initiatives include establishing an engine
service center at TAMP-SA (FWD) to test suspect engines with
portable engine analyzers and provide technical assistance for
on aircraft repairs.   Establishment of a limited depot engIne
repair facility at TAMP-SA (BASE)  in Abu Dhabi will include a
Mobile Engine Test Stand (METS). The test stand is capable of
testing T-53 series (AH/UH-l) and T-700 series
(UH-60/AH-64) engines.   T-55 (CH-47) engines will be
capable of being tested by Jan 91.   The overall objective
is to minimize the effect of the environment and reduce
unserviceable engine turn around time.

     (5)  Aircraft particle separators..   The UH-l/AH-l/CH-47
aircraft deployed to SWA began to experience power loss and
premature failures with less than 25 flight hours.    Sand and
dust ingested into the engine operations severely limits
capabilities and readiness.   Of the UH-l aircraft deployed to
SWA, 40% had Improved Particle Separators installed.    Ki~s ~~~~
been sent for the remaining aircraft.    Installation  ecar.
Oct 90 and requires 25 man hours per aircraft.    The AH-
required the application of an improved particle separator for
engine protection.   The AH-lF going into SWA to replace the
AH-lE will have the kits installed prior to arrival.    The AH-IF
for AH-lE changeout will be completed in Dec 90.    The AH-lF now
in SWA will have improved particle separators installed there.
The modification is extensive requiring 280 man hours.    Engine
Air Particle Separators (EAPS) kits have been designed for the
CH-47D.   Funding has been provided to purchase the first 31 of
the 100 required kits.   First production of 20 EAPS is
scheduled to be available by mid January 91.    Installation will
require 250-300 man hours and will be accomplished in SWA.    All
in country modifications will be accomplished by contractors.
A particle separator for the UH-60 APU has been developed and
first deliveries are scheduled for December 90.
