[Docket No. NHTSA-2011-0175]

Hybrid III 10-Year-Old Child Test Dummy; Corrections; 
Incorporation by Reference

AGENCY: National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation (DOT).

ACTION: Technical amendments.

-----------------------------------------------------------------------

SUMMARY: NHTSA published a document in the Federal Register on February 
27, 2012 (77 FR 11651), establishing specifications and qualification 
requirements for a Hybrid III 10-year-old child size test dummy. The 
regulatory text adopted by that document contained errors, as did some 
of the drawings of the test dummy and other materials incorporated by 
reference pertaining to the test dummy. This document corrects those 
errors by revising regulatory text and incorporating by reference a 
corrected drawing package. We have also made conforming changes to the 
parts list and users' manual for the dummy, which this document also 
incorporates by reference.

DATES: Effective date: June 23, 2015. The incorporation by reference of 
the publications listed in this document has been approved by the 
Director of the Federal Register as of June 23, 2015.

FOR FURTHER INFORMATION CONTACT: Peter Martin, NHTSA Office of 
Crashworthiness Standards, 1200 New Jersey Avenue SE., Washington, DC 
20590, telephone (202) 366-5668, fax (202) 493-2990, or Deirdre Fujita, 
NHTSA Office of Chief Counsel, 1200 New Jersey Avenue SE., Washington, 
DC 20590, telephone (202) 366-2992, fax (202) 366-3820.

SUPPLEMENTARY INFORMATION: 
    This document corrects 49 CFR part 572, ``Anthropomorphic Test 
Devices,''

[[Page 35859]]

Subpart T, ``Hybrid III 10-Year-Old Child Test Dummy (HIII-10C).'' 
NHTSA published a final rule on February 27, 2012 (77 FR 11651), 
establishing Subpart T, which contains specifications and qualification 
requirements for the HIII-10C. The regulatory text adopted by that 
document contains errors, as do some of the drawings and other 
materials incorporated by reference pertaining to the test dummy. This 
document corrects those errors by revising regulatory text and 
incorporating by reference a corrected drawing package, parts list and 
users' manual.

Need for Correction

Corrected Regulatory Text

    The following corrections are made to the regulatory text.
    a. Sections 572.170 and 572.171 of subpart T incorporate by 
reference a drawings and inspection package, a parts/drawing list, and 
a users' manual (``Procedures for Assembly, Disassembly and 
Inspection'' (``PADI'')) for the HIII-10C by name and by date. NHTSA is 
correcting several drawings in the package, and is making conforming 
changes to the parts list and to several figures in the PADI. For ease 
of use, rather than switch out individual drawings from the previous 
drawings package and individual pages from the original PADI and risk 
confusion by users in the future about which drawings and pages were 
replaced, NHTSA is incorporating by reference a new set of materials. 
We are referencing a new drawings and inspection package that has the 
corrected drawings, a new parts/drawing list, and a new PADI. All these 
new materials are dated March 2015. We are amending Sec.  572.170 and 
Sec.  572.171 to reference the new versions of the materials.
    b. The February 2012 final rule incorrectly specifies in 49 CFR 
572.177(a)(1) that the thorax impact probe mass is 6.89  
0.012 kilograms (kg) (15.2  0.05 pounds (lb)). Figure T4 of 
subpart T correctly lists the thorax impact probe mass as ``6.89  0.05 kg (15.2  0.1 lb).'' We are correcting the 
second sentence of 49 CFR 572.177(a)(1) so that it refers to ``6.89 
 0.05 kg (15.2  0.1 lb).''
    Likewise, the February 2012 final rule incorrectly specifies in 
Sec.  572.177(a)(2) that the knee impact probe mass is 1.91  0.01 kg (4.21  0.02 lb). Figure T6 of subpart T 
correctly lists the knee impact probe mass as ``1.91  0.05 
kg (4.2  0.1 lb).'' We are correcting the second sentence 
of 49 CFR 572.177(a)(2) to reference a mass of 1.91  0.05 
kg (4.21  0.1 lb).
    c. The February 2012 final rule inadvertently excluded a 
specification for the filter class used for the knee probe acceleration 
and for the thorax probe acceleration. The filter class used for the 
knee probe acceleration is SAE International (SAE) Channel Frequency 
Class (CFC) 600. CFC 600 has historically been applied to other dummy 
knee probe accelerations and NHTSA used CFC 600 in developmental 
testing of the HIII-10C. The filter class used for the thorax probe 
acceleration is CFC 180. NHTSA specifies the CFC 180 filter class with 
other test dummies and used it in developing the HIII-10C. Accordingly, 
NHTSA corrects 49 CFR 572.177(c) by adding the filter classes for the 
knee and thorax probe accelerations.

Corrected Drawings

Drawing 420-5120, Upper Leg Flesh
    In the revisions table for this drawing, in Rev F, the overall 
Upper Leg Flesh height dimension is correctly specified as ``4.50 +.06/
-.18 (was 4.5 +.16/-.13).'' Elsewhere on the drawing, the height 
dimension next to the part does not match this value in the table. We 
have corrected the height dimension next to the part to match that of 
the table.
    In Drawing 420-5120, the dimension for the overall Upper Leg Flesh 
width is correctly listed, next to the part, as ``4.92 +.05/-.20.'' In 
the revisions table, Rev F, the width dimension is different and 
incorrect. We have corrected the revisions table to match the dimension 
listed next to the part.
Drawing 420-4300, Abdomen
    In the revision history table, Rev F, the width of the abdomen 
pocket is correctly stated as (3.77) and the depth is correctly stated 
as (2.14). Elsewhere on the drawing, the dimensions listed for those 
parts do not match those correct dimensions in the revision history 
table. We have corrected the drawing to match the correct dimensions in 
the table.
    In the revision history table, Rev E, Note #2 had read: ``All 
Dimensional Tolerances Are 0.12 inch.'' The note was 
incorrectly removed, and in Rev F, a 0.06 inch tolerance 
was incorrectly added to two dimensions (0.75 0.06 and 0.62 
0.06). The 0.06 inch tolerance is in error; it 
is an unrealistic dimensional requirement for a molded part. We have 
revised the drawing to reestablished the 0.12 inch 
tolerance for this part.
Drawing 420-1001, Skull, Machining, 6-Axis
    The drawing package incorporated by the February 2012 final rule 
had drawing 880105-102, which had an error with respect to the 
dimensions called out for the center of gravity (CG) location of the 
skull. The correct CG dimensions for the head assembly are in drawing 
420-0000, Sheet 4 of 5, as follows: CGx = 2.330  0.100 inch 
and CGz = 1.200  0.100 inch. We have removed drawing 
880105-102 and have revised drawing 420-1001 (Rev D) to add information 
on the CG location.
Revisions Relating to Shoulder Assembly Drawings
    Some of the drawings of the HIII-10C's shoulder area are incorrect 
because they depict the design of the dummy at the time of our 
publication of the notice of proposed rulemaking (NPRM) \1\ preceding 
the February 2012 final rule, and not the design of the HIII-10C as it 
was adopted by the final rule. As adopted by the final rule, the HIII-
10C has a shoulder assembly design that can be modified by switching a 
part of the shoulder assembly (the shoulder yoke), to enable the dummy 
shoulder to accommodate either a load cell or a structural replacement 
(SR) in place of a load cell. The drawings adopted by the final rule 
show the shoulder yoke that accommodates an SR, but we inadvertently 
did not include drawings showing the HIII-10C with the shoulder yoke 
assembly that accommodates a load cell. We have corrected this 
oversight by including in the new drawing package drawings of the 
alternate shoulder yoke assembly that accommodates a load cell, and 
drawings of the load cell and assorted hardware.

---------------------------------------------------------------------------

Corrected PADI

    We have revised various figures in the PADI to conform the manual 
to the changes discussed above. Most of the revisions relate to using 
the shoulder yoke assembly when using the HIII-10C with a shoulder load 
cell. The revised figures are: 12, 21, 22, 24, 29, 82 and 83.
