Reliability and Safety of Aged Electrical
and Dynamic Equipment
This report details the
methods used to determine the usable service life of electrical
systems and dynamic equipment. It categorizes the broad range of
approaches used by government, academic, trade, safety, insurance,
and private organizations to determine when electrical or dynamic
equipment has reached the end of its usable service life and
provides a recommended age determination approach factor to be
implemented by NASA.
NASA’s once cutting edge scientific and space launch facilities
are getting old.
- The 2004 Current Replacement Value Weighted Age in NASA is 43
years.
- 805 facilities were constructed prior to 1961
- Some NASA equipment is over 85 years old
In addition, during the FY03 NASA Deferred Maintenance (DM)
Assessment, of the 439 NASA facilities 43 years or older the
electrical systems were only rated at 3.0 (fair). This rating of
fair reflects that there is a large amount of older high-energy
electrical and dynamic mechanical equipment across NASA that may not
meet all current safety standards, or be as reliable as required to
meet mission operations. For these reasons, there is a need to
determine an equipment age that defines an acceptable level of risk,
so that the agency may realize improved safety and mission assurance
and avoid any incidents that may be caused by aged electrical or
dynamic equipment.
