History of Electrical Standard Practices Manual (ESPM) and ELECTRICAL WIRING INTERCONNECTION SYSTEMS COURSE
The investigation into a fatal accident on 17 July 1996 resulted in a heightened awareness of the importance of maintaining the integrity
of aircraft.
In February 1997: The US White House Commission on Aviation Safety and Security (WHCSS) recommended to the #FAA to work in cooperation with airlines and manufacturers to expand the FAA’s Aging Airplane Programme to include non-structural components.
In July 1998: The FAA issued the Aging Transport Non-Structural Systems Plan to address the WHCSS recommendation.
The Aging Systems Plan focussed specifically on wiring systems.
FAA set-up an Aging Transport Systems Rulemaking Advisory Committee (ATSRAC) to give recommendations on aircraft safety issues and propose enhancements to current procedures.

ELECTRICAL STANDARD PRACTICES MANUAL
To anticipate ATSRAC Tasks 4 and 7 recommendations, #airbus decided to develop a new electrical standard wiring practices manual
to take over from the AMM Chapter 20. A generic Electrical Standard Practices Manual (ESPM) was launched in April 2001. This new manual encompasses the old Chapter 20 and new chapters.
#airbus Training Division has developed a wiring training course based on the ATSRAC Task 5 and 8 recommendations.
This training called “Electrical Wiring Interconnection Systems” course is to help operators better understand and maintain their aircraft electrical installation.
