MIL-F-18372(Aer)
a. The consequences
b. The compensating provisions
c. Evaluation of the reliability of the critical component
3.5.2.4 Tests - For Type II and Type III Systems a working mock-up or simulator of the
flight control system shall be constructed. Tests shall be conducted to check out the operation
and stability of the system under simulated flight conditions.
3.5.2.5 System Test Reports - Prior to the conduction of the tests of 3.5.2.4, a report shall
be submitted, for the approval of the Bureau of Aeronautics, outlining the test procedure. At the
conclusion of the tests, a complete report of the tests shall be submitted. This report shall
include a comparison of the test results with those obtained from the analysis of 3.3.2.2. Upon
completion of the contractors flight test program, a report covering the performance of the flight
control system and a comparison of the flight test results with the results of the theoretical
and simulated analysis shall also be submitted.
3.5.3 Production Aircraft - The following data shall be submitted:
a. Schematic arrangement of the flight control system. (See 3.5.3.1)
b. Flight control system design report. (See 3.5.3.2)
c. Plan and profile or isometric of the complete flight control system installation.
(See 3.5.3.3)
c. Flight control system installation drawings. (See 3.5.3.4)
e. Flight control system component cross-section assembly drawings where necessary
for clarification and for approval of individual units such as actuators, synthetic
feel devices, spring cartridges, etc. (See 3.5.3.5)
f. Flight control system failure analysis report. (See 3.5.3.6)
g. Flight control system test. (See 3.5.3.7)
3.5.3.1 Schematic Arrangement -SUBMIT SAME AS 3.5.2.1 - Except bring up to date for
production model airplane.
3.5.3.2 Desing Report - SUBMIT SAME AS 3.5.2.2 - Except bring up to date with latest
available information.
3.5.3.3 Plan and Profile or Perspective of the Complete Flight Control System - The drawing of
the complete flight control system shall be a plan and profile projection or a perspective type
illustration. It shall show the complete control system installation including component and
mechanical arrangement and shall be on the backgroud of the aircraft outline. Where necessary,
sufficient aircraft structure shall be shown (may be in phantom) so that the relative vulnerability
of the systems may be ascertained.
3.5.3.4 Installation Drawings - The installation drawings shall show the complete flight control
system including mechanical, hydraulic or other power system components in addition to the motion
geometry (trends) of principal linkages from the pilot's control to the operating surface. All
attaching points, brackets, adjustment provisions, stops and rigging points, shall be indicated. These
drawings shall be in sufficient detail to show sizes of cables, typical terminals, end fittings, levers,
etc. The parts shall be labeled as to name and part number.
3.5.3.5 Component Cross-Section Assembly Drawings - Component cross-section assembly drawings
shall contain sufficient information so that an evaluation of the unit can be made.
3.5.3.6 Failure Analysis Report - SUBMIT SAME AS 3.5.2.3 - Except bring up to date with latest
revisions to the flight control system.
3.5.3.7 Tests - SUBMIT SAME AS 3.5.2.4 - Except bring up to date.
3.5.3.8 Test Report - SUBMIT SAME AS 3.5.2.5 - Except bring up to date with results of latest
tests.
