SUPPLEMENTARY INFORMATION:

I. Background

    On May 4, 2016, NHTSA issued, and Takata agreed to, an Amendment to 
the November 3, 2015 Consent Order (the ``Amendment''), under which 
Takata is bound to declare a defect in all driver and passenger 
inflators that contain an ammonium nitrate-based propellant and do not 
contain a moisture-absorbing desiccant. Such defect declarations are to 
be made on a rolling basis. See Amendment at ] 14. Takata timely 
submitted the first scheduled DIR on May 16, 2016. The next DIR is due 
to be filed on December 31, 2016, and is expected to include passenger 
inflators installed as original equipment on certain motor vehicles 
manufactured by GM (the ``covered passenger inflators'').
    The Amendment sets forth the following procedure under which the 
DIR schedule may be modified or amended:

    Based on the presentation of additional test data, analysis, or 
other relevant and appropriate evidence, by Takata, an automobile 
manufacturer, or any other credible source, NHTSA may, after 
consultation with Takata, alter the schedule set forth in Paragraph 
14 to modify or amend a DIR or to defer certain inflator types or 
vehicles, or a portion thereof, to a later DIR filing date. Any such 
evidence must be submitted to NHTSA no later than one-hundred-twenty 
(120) days before the relevant DIR filing date. This paragraph 
applies only to the DIRs scheduled to be issued on or after December 
31, 2016 under the schedule established by Paragraph 14 of this 
Amendment.

See Amendment at ] 17. On July 22, 2016, NHTSA issued Enforcement 
Guidance Bulletin 2016-03 to inform the public of the process and 
procedure the Agency had established in connection with Paragraph 17 of 
the Amendment, as well as the standards and criteria that would guide 
Agency decision-making. See 81 FR 47854.
    On September 2, 2016, GM filed a petition pursuant to Paragraph 17 
of the Amendment and Enforcement Guidance Bulletin 2016-03. Therein, GM 
has requested that NHTSA modify the DIR

schedule to delay the inclusion of covered GM passenger-side inflators 
from December 31, 2016 to December 31, 2017. This notice of receipt of 
GM's petition is published in accordance with Enforcement Guidance 
Bulletin 2016-03 and does not represent any Agency decision or other 
exercise of judgment concerning the merits of the petition.

II. Class of Motor Vehicles Involved

    GM's petition involves certain GMT900 vehicles that contain the 
covered passenger inflators (designated as inflator types ``SPI YP'' 
and ``PSPI-L YD''). GMT900 is a GM-specific vehicle platform that forms 
the structural foundation for a variety of GM trucks and sport utility 
vehicles, including: Chevrolet Silverado 1500, GMC Sierra 1500, 
Chevrolet Silverado 2500/3500, GMC Sierra 2500/3500, Chevrolet Tahoe, 
Chevrolet Suburban, Chevrolet Avalanche, GMC Yukon, GMC Yukon XL, 
Cadillac Escalade, Cadillac Escalade ESV, and Cadillac Escalade EXT.
    The next Takata DIR, which is due to be filed on December 31, 2016, 
is expected to include the following GMT900 vehicles:
     In Zone A, model year 2012 GMT900 vehicles. Zone A 
comprises the following states and U.S. territories: Alabama, 
California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South 
Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern 
Mariana Islands (Saipan), and the U.S. Virgin Islands. See Amendment at 
] 7.a.
     In Zone B, certain model year 2009 GMT900 vehicles. Zone B 
comprises the following states: Arizona, Arkansas, Delaware, District 
of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, 
Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, 
Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia. See 
Amendment at ] 7.b.
     In Zone C, certain model year 2007 and 2008 GMT900 
vehicles. Zone C comprises the following states: Alaska, Colorado, 
Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, 
Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, 
South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming. See 
Amendment at ] 7.c.

III. Summary of GM's Petition

    GM's petition states its belief that the requested modification to 
the DIR schedule will not pose an unreasonable risk to motor vehicle 
safety. In support of this contention, GM states that it has studied 
the long-term performance of the covered passenger inflators and has 
conducted an analysis of the ballistic performance of the covered 
passenger inflators. Based upon this analysis, GM states that the 
covered passenger inflators are not currently at risk of rupture. 
According to the petition, GM's position is based upon the following: 
An estimated 44,000 Takata passenger inflator deployments in GMT900 
vehicles without a rupture; ballistic tests of 1055 covered passenger 
inflators without a rupture or sign of abnormal deployment; deployment 
of 12 inflators artificially exposed to additional humidity and 
temperature cycling without a rupture or sign of abnormal deployment; 
and analysis, through stress-strength interference, indicating that the 
propellant in older covered passenger inflators has not degraded to a 
sufficient degree to create rupture risk.
    GM further states that the covered passenger inflators are not used 
by any other original equipment manufacturer and have a number of 
unique design features that influence burn rates and internal ballistic 
dynamics, including greater vent-area-to-propellant-mass ratios, steel 
end caps, and thinner propellant wafers. In addition, GM states that 
the physical environment of the GMT900 vehicles better protects the 
covered passenger inflators from the temperature cycling that can cause 
rupture. More specifically, GM notes that the GMT900 vehicles have 
larger interior volumes than smaller passenger cars, and are equipped 
with solar-absorbing windshields and side glass.
    Finally, GM states that it has retained a third-party expert to 
conduct a long-term aging study that will estimate the service life 
expectancy of the covered passenger inflators in the GMT900 vehicles. 
GM anticipates that this study will be complete in August 2017.
    For these reasons, GM requests that NHTSA amend the DIR schedule 
pursuant to Paragraph 17 of the Amendment to delay the inclusion of the 
covered passenger inflators until the December 31, 2017 DIR filing.
