4. QUALITY ASSURANCE PROVISIONS
4.1
Test Requirements - Appropriate testing, as outlined herein, shall be conducted
throughout the developoment and reduction of flight control systems in order to insure proper design
and performance and also continuing quality throughout production. The specific tests required
shall be specified in the detailed specifications for the components and systems. If the tests required
by the detailed specifications are inadequate to prove that the flight control system and flight control
system installation incorporate the specified requirements, the contractor shall propose amendments
to the contract to include tests which will provide adequate proof. If applicable tests are available,
the contractor shall, in lieu of repeating tests, propose amendments to the contract to require the
submittal of these data, supplemented by sufficient information to substantiate their applicability.
4.1.1
Test Witnesses - Before conducting a required test, an authorized procurement
activity representative shall be notified so that he or his representative, may witness the test and
certify results and observations contained in the test reports. When the procuring activity repre-
sentative is notified, he shall be informed if the test is such that interpretation of the behavior of
the test article is likely to require engineering knowledge and experience. in which case he will
provide a qualified engineer who will witness the test and certify the results and observations during
the test.
4.2
Design Approval Tests - Design approval tests are accomplished on a sample or
samples to determine compliance with the requirements of an investigation, study, research,
development contract or purchase order, experimental and developmental specifications, exhibits
or other requirements applicable thereto. A breadboard model, experimental model or develop-
mental model shall be constructed and appropriate tests shall be conducted to insure that the
operational and dynamic characteristics of the systems and components meet the requirements
which have been established and are reliable in their performance characteristics.
4.2.1
Simulator Testing - Tests shall be made with equipment mounted on a simulator
and with gains adjusted as recommended by the manufacturer. The simulator shall include all
relevant control rigging, hinge moments, artifical feel devices, and tilt tables, if required. In
addition, it shall include a computer to simulate aircraft response, selectable for all conditions of
flight.
4.3
Preproduction Tests - Preproduction tests are those tests accomplished on a
sample or samples, representative of an article or system to be proceed or delivered on a produc-
tion contract or purchase order, to determine that the article meets specifcation requirements.
These tests shall be conducted by the procuring activity or contractor at the location or locations as
specified in the contract, purchase order or detailed specification. A test report in accordance with
3.5.6 shall be submitted to the procuring activity for approval.
4.3.1
Sampling - Usually, three systems or components shall be made available to
accomplish the preproduction tests. Allocation of, and additional or different quantities required
shall be as specified in the contract or purchase order.
