The FAA's summary their words, unchanged

These special conditions are issued for Boeing Model 767-27C airplanes modified by installation of an Airborne Warning and Control System (AWACS). These airplanes will be equipped with an oxygen system utilizing liquid oxygen (LOX). The applicable regulations do not contain adequate or appropriate safety standards for the design and installation of oxygen systems utilizing LOX for storage. These standards are intended to ensure that the design and installation of the liquid oxygen system is such that a level of safety equivalent to that established by the airworthiness standards for transport category airplanes is provided.
