of all inspection requirements as specified herein. Except as otherwise
specified in the contract or purchase order, the contractor may use his own
or any other facilities suitable for the performance of the inspection
requirements specified herein unless disapproved by the Government. The
Government reserves the right to perform any of the inspections set forth
in the specification where such inspections are deemed necessary to assure
supplies and services conform to prescribed requirements.
4.2 Development testing (DT), reviews, and audits. Development testing
(DT), reviews, and audits for the escape system shall include, but shall not
be limited to, the test and inspection regimen described below. All tests
specified shall be successfully completed in accordance with 4.7.6. For
all ejection testing, the contractor shall also comply with the additional
test conditions and data requirements specified in the appendix. Design
reviews, audits, and similar events shall be conducted as specified in the
following paragraphs or, where designated, by the contractor with procuring
activity representatives in attendance. The objective of these events is
to ensure, in an orderly manner, that the escape system design is compatible
with the fully-equipped aircrewmember and the aircraft, and is in accordance
with the specification requirements. The events shall be conducted and
approved in the sequence herein specified. The test and inspection program
for the development of the escape system shall consist of the demonstration
and validation phase, DT-I, and the full scale development phase, DT-II.
Each phase shall be further subdivided as follows:
a.
Initial engineering demonstration and validation, DT-IA. Initial
engineering demonstration and validation shall include the tests
specified in 4.3 and such other tests as required to generate
sufficient data to satisfy the initial functional configuration
audit requirements of 4.3.2.1 for all components and subsystems
not already qualified in accordance with the requirements of this
specification (see 4.3.1.1). The reviews and audits to be
conducted during DT-IA shall include the following:
(1) Engineering proofing article I (EPA-I) review (see 4.3.1).
(a) Initial qualification status review (IQSR) (see 4.3.1.1).
(2) Engineering proofing article II (EPA-II) review (see 4.3.2).
(a) Initial functional configuration audit (IFCA) (see
4.3.2.1).
(b) Field maintainability article I (FMA-I) (see 4.3.2.3).
