accommodation and task performance. The contractor shall prepare and install
in each appropriate aircrewmember station an engineering proofing article
representing the proposed testing baseline configuration (see 4.3.2.4).
Parts need not be manufactured by production processes. In a program involving
retrofit of the ejection seat assembly and associated elements into a specified
aircraft, installation of each proofing article shall be conducted in accordance
with formalized installation instructions prepared by the contractor and will
be observed by representatives of the-procuring activity. The ejection seat
back tangent (see 6.4.3) and the seated surface tangent (see 6.4.4) shall be
depicted on the ejection seat. The ejection seat intersect point (SIP) (see
6.4.1) location and the projected tangents shall be defined for visual
reference. If practical, side panel identification marks or pilot holes shall
be used for location of the SIP. If impractical to identify the SIP by
structural points, a durable and rigid template shall be provided to determine
the physical location of the SIP. The contractor shall comply with appendix
2 to MIL-M-8650. Complex components, subsystems, and operations shall be
illustrated and described in detail so that the participants reviewing the
system can verify quickly and accurately the design, assembly, and operation
of each element of the escape system. The same tests and demonstrations as
required by 4.3.1.2.1 throuqh 4.3.1.2.5 shall be performed. At the completion
of these tests, the contractor shall maintain the proofing articles in
accordance with 4.3.1.2.
4.3.2.3 Field maintainability article I (FMA-I) review. The contractor
shall prepare a maintainability article(s) for review within thirty days
prior to and thirty days following the completion of the EPA-II review.
parts need not be manufactured by production processes. The FMA-I maintain-
ability article shall be the same configuration as the EPA-II proofing
article. The function of the FMA-I review is to determine whether the escape
system design meets all specified maintainability requirements. Adequate
maintenance instructions and peculiar support equipment evaluation articles
needed to accomplish and evaluate all maintenance requirements and actions
at each maintenance level shall be provided with the maintainability article,
The peculiar support equipment evaluation articles shall be the proposed
final design, but need not be manufactured by planned production processes;
however, the equipment shall be capable of safely performing the specified
tasks. The escape system shall be subjected to a field maintainability
review conducted by the procuring activity in accordance with MIL-STD-2067.
The objective of this review shall be to:
a. Ensure system and component maintainability.
b. Develop information for evaluating contractor recommended
maintenance procedures and practices.
c. Determine the support equipment and peculiar support equipment
suitability for performing the required maintenance tasks
in a fleet maintenance environment.
d. Evaluate susceptibility of escape system components to
damage during cockpit aircraft maintenance.
All ballistic components of the prototype escape system shall be inert;
however, all mechanical firing mechanisms shall be in working order.
