The AN/ASH-37(V) Structural Data Recording Set (SDRS) provides the capability for
NAVAIR Engineering Code 4.3.3 to better predict aircraft Fatigue Life Expended (FLE)
that enables the Navy to accurately and safely maximize the airframe service life
of selected fixed wing platforms. The AN/UYQ-76A Maintenance Data Processing Station
(MDPS) Grownd Support Equipment is used to periodically download SDRS data that
is sent to NAVAIR 4.3.3 IAW NAVAIRINST 13920.1H. NAVAIR 4.3.3 analyzes the data
and provides Structural Appraisal of Fatigue Effects (SAFE) reports back to the
fleet. SDRS equipped platforms include E-2C, C-2A, F-14A, S-3B, P-3C, C-130, and
EA-6B.
Acquisition and installation of the SDRS and MDPS has been completed. PMA209 continues
to provide hardware and software support for SDRS and MDPS to the fleet, NAVAIR
4.3.3 and NAVICP.
