ALTERNATIVE EQUIPMENT
You may consider equipment using new technologies but must make sure the
standards in this document are met; cost effectiveness, reliability, availability,
maintainability, and service life are not compromised; and adequate training and logistic
support for the substitute equipment is available. The waiver requirements of
paragraphs 1-10 and 1-11 apply. See also paragraph 13-16.
13-7
EMERGENCY SUBSTITUTION
In emergency situations where facility restoration would be significantly delayed by non-
availability of replacement parts, equipment or devices not meeting the applicable
specifications may be substituted. Base Civil Engineering, airfield operations, and flying
safety offices must all coordinate these substitutions and notify the major command.
Remove the substitute equipment from service and replace it with approved equipment
as soon as it becomes available.
