4.3.1.1 Corrosion protection. Corrosion practices and protection of dissimilar metal interfaces shall be
determined by inspect ion for compliance with MIL-STD-889 and MIL-F-7179.
4.3.1.2 Finishes. The inertia reel shall be inspected to determine if protective finishes are utilized and are in
accordance with MIL-S-5002 for surface treatments and inorganic coatings and MIL-F-18264 and
MIL-HDBK-132 for organic finishes. Each inertia reel shall be inspected for cracks, chips, or scales. Each inertia
reel exterior color shall be inspected for compliance with FED-STD-595 #37038, lusterless black.
4.3.1.3 Plating. The inertia reel shall be inspected to determine whether ail steel parts in contact with
aluminum or aluminum alloy are coated with aluminum by ion vapor deposition in accordance with MIL-C-83488,
Type II, class 1.
4.3.1.4 Anodizing. The inertia reel shall be inspected to determine that all aluminum and aluminum alloy
parts are anodized in accordance with MIL-A-8625. Type II or Type III, as appropriate.
4.3.2 Screw Threads. All screw threads of the inertia reel shall be inspected during pans interchangeability
demonstration (see 4.4.2) for conformance with MIL-S-7742. Screws shall be inspected to determine if they have
positive locking capability.
4.4 Design and constnuction verification. The inertia reel or subassemblies shall be inspected visually
following each individual environmental conditioning test to ensure that the inertia reel performance is not
degraded below specified levels during exposure or post-exposure testing. Maintenance assembly and disassembly
for replacement of thc webbing or cable and the control handle and cable assembly shall be demonstrated without
the use of special tools.
4.4.1 Standard parts determination. The inertia reel drawings shall be inspected to verify the use of MS and
AN standard parts. Electronic parts shall be inspected to verify the use of Military Specification compliant
components.
4.4.2 Parts interchangeability demonstration. Parts interchangeability shall be verified by demonstration.
Three inertia reds shall be randomly selected from the test sample pool. The serial numbers shall be noted and
quality conformance tests conducted. Five functionally-critical parts (excluding fasteners) shall be randomly
selected to demonstrate intercharngeability. The same 5 randomly selected parts shall be removed from all 3 inertia
reels and mixed together, All 3 inertia reels shall then be reassembled using this pool of parts. The iertia reel
shal1 be recalibrated and quality conformance tests conducted to demonstrate no performance degradation below
the performance levels specified herein.
4.4.3 Subassemblies. Subassemblies may be qualified independent of the complete inertia reel assembly. The
required tests are listed in Table III and sample information (see 4.2.1.1).
4.4.3.1 Inertia reel housing subassembly demonstration. The inertia reel housing mechanism cover shall be
removed using common hand tools to assess compliance with the requirement for the task to be performed within a
maximum of 5 minutes to allow for recalibration of the internal mechanism.
4.4.3.1.1 Inertia reel locking mechanism actuation demonstration.
4.4.3.1.1.1 inertia reel locking mechanism actuation (MA- I type inertia reel) demonstration. The MA-1 type
inertia reel locking mechanism shall be functioned using an MA-1 type manual control handle subassembly
attached to an MA-1 type manual control cable subassembly to ascertain whether the cable throw (stroke) of 1.21
0.03 inch fully and completely activates the MA-1 type inertia reel lock/unlock mechanism. This demonstration
shall be repeated 5 times.
