4.4.3.4.3 Manual control cable subassembly interchangeability demonstration. The manual control cable
subassembly shall be attached to all QPL inertia reel subassemblies and to all QPL manual control handle
subassemblies and functioned to permit verification that the inertia reel performance (manual and automatic
modes) meets the requirements specified herein. The manual control cable subassembly shall be operated each
time it is mated to a different inertia reel or manual control handle to demonstrate performance without any
degradation. The manual control cable shall be tested to verify compliance with the 25 pound load unlock test,
environmental tests, and life cycle tests. The manual control cable shall be inspected to verify compliance with
Figures 12 through 15, as applicable for each type of inertia reel configuration.
4.4.3.4.3.1 Manual control cable subassembly (MA-1 type inertia reel) interchangeability demonstration. The
manual control cable subassembly for the MA-1 type inertia reel, shall be attached to all QPL MA-1 type inertia
reels and all QPL MA- I manual control handle subassemblies and functioned to verify interchangeability without
modification. The manual control cable subassembly shall function in accordance with all requirements specified
herein when mated with each of the QPL inertia reels and manual control handle subassemblies.
4.4.3.4.3.2 Manual control cable subassembly (MA-2 type inertia reel) interchangeability demonstration. The
manual control cable subassembly for the MA-2 type inertia reel, shall be attached to all QPL MA-2 type inertia
reels and all QPL MA-2 manual control handle subassemblies and functioned to verify interchangeability without
modification. The manual control cable subassemblies shall function in accordance with all requirements specified
herein when mated with each of the QPL inertia reels and manual control handle subassemblies.
4.4.3.4.3.3 Manual control cable subassembly (MA-6, MA-8, MA-14, and MA-16 type inertia reels)
interchangeability demonstration. The manual control cable subassembly of any MA-6, MA-8, MA-14, and
MA-16 type inertia reels, shall be attached to all QPL inertia reds of these types and all QPL manual control
handle subassemblies of these types and functioned to verify interchangeability without modification. The manual
control cable subassemblies shall function in accordance with all requirements specified herein when mated with
each of the QPL inertia reels and manual control handle subassemblies.
4.4.3.4.4 Manual control cable subassembly load transmission demonstration. The manual control cable
subassembly, while attached to an inertia reel and manual control handle subassembly, shall be functioned to verify
the capability of the manual control cable subassembly to transmit manual control handle loads required to actuate
the inertia reel locking mechanism when the cable or webbing lead-in swap is tensioned with a 25 pound load.
4.4.3.4.5 Manual control cable subassembly throw The manual control cable subassembly. while attached to
a manual control handle subassembly, shall be functioned to ascertain the manual control cable throw (stroke)
distance produced through the attached manual control handle throw angle.
4.4.3.4.6 Manual control cable subassembly qualification. The manual control cable subassembly shall be
subjected to the following tests/inspections when qualified only as a subassembly:
a. Dimensions (see Figures 12-15).
b. Materials (see 4.3).
c. Design and construction (see 4.4).
d. Manual control cable subassembly design inspection (see 4.4.3.4).
e. Cable throw (stroke) (see 4.4.3.4.1, 4.4.3.4.5).
f. Adjustability (see 4.4.3.4.2).
g. Interchangeability (see 4.4.3.4.3).
