ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for The 
Boeing Company Model 737-300, -400, and -700 series airplanes, modified 
to a Bedek Division Special Freighter (BDSF) by Supplemental Type 
Certificate (STC) ST01566LA, ST01961SE, or ST02556SE, with a 9G rigid 
barrier. An emergency AD was sent to all known U.S. owners and 
operators of these airplanes. This AD requires complying with loading 
restrictions and methods. This AD was prompted by a review of the 
manufacturing process for the 9G rigid barrier installed on BDSF 
conversions that identified a manufacturing non-compliance. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective January 21, 2020 to all persons except 
those persons to whom it was made immediately effective by Emergency AD 
2019-25-55, issued on December 13, 2019, which contained the 
requirements of this amendment.

SUPPLEMENTARY INFORMATION:

Discussion

    The Civil Aviation Authority of Israel (CAAI), which is the 
aviation authority for Israel, has issued Israeli AD ISR-I-53-2019-12-
6, dated December 12, 2019 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for The Boeing Company Model 737-300, -400, and -700 
series airplanes, modified to a BDSF by STC ST01566LA, ST01961SE, or 
ST02556SE, with a 9G rigid barrier. You may examine the MCAI on the 
internet at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2019-0986.
    On December 13, 2019, the FAA issued Emergency AD 2019-25-55, which 
requires complying with loading restrictions and methods. The emergency 
AD was sent previously to all known U.S. owners and operators of these 
airplanes. This action was prompted by a review of the manufacturing 
process for the 9G rigid barrier installed on BDSF conversions that 
identified a manufacturing non-compliance. It has been found that the 
surface preparation before bonding was improperly done, which can 
affect the 9G rigid barrier's strength characteristics. This condition, 
if not addressed, could result in the potential failure of the 9G rigid 
barrier under certain emergency landing loads, which could injure 
occupants. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Israel Aerospace Industries Service Bulletin 365-
00-054, dated December 2019. This service information describes loading 
restrictions and methods that include reducing the cargo weights for 
each loading configuration and using additional straps when necessary 
to address 9G rigid barrier manufacturing non-compliance. This service 
information is reasonably available because the interested parties have 
access to it through their normal course of business or by the means 
identified in the ADDRESSES section.

FAA's Determination

    Pursuant to a bilateral agreement with the State of Design 
Authority, the FAA has been notified of the unsafe

[[Page 3255]]

condition described in the MCAI and service information referenced 
above. The FAA is issuing this AD because the agency evaluated all 
pertinent information and determined the unsafe condition exists and is 
likely to exist or develop on other products of the same type design.

AD Requirements

    This AD requires complying with the loading restrictions and 
methods specified in the service information described previously, 
except as discussed under ``Differences Between this AD and the Service 
Information.''

Differences Between This AD and the Service Information

    Where Israel Aerospace Industries Service Bulletin 365-00-054, 
dated December 2019, specifies using cargo restraint straps rated at a 
minimum of 7,500 pounds, this AD requires using Technical Standard 
Order TSO-C172 cargo restraint straps; that TSO specifies a load rating 
of 5,000 pounds. This exception corrects the Israel Aerospace 
Industries service bulletin's reference to a TSO-C172 cargo strap load 
rating of 7,500 pounds; the cargo strap load capability specified in 
the TSO is 5,000 pounds.
    This AD specifies that the provisions for restraining cargo 
directly to a pallet or the airplane as provided in the existing 
airplane flight manual (AFM) (reference section 1-68-XX of the Israel 
Aerospace Industries Weight and Balance Manual (WBM)) can only be used 
if that cargo and all cargo aft of that location are restrained to a 
forward load factor of 9G. This exception corrects an omission in the 
Israel Aerospace Industries' service bulletin.

Interim Action

    The FAA considers this AD interim action.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
Emergency AD 2019-25-55, issued on December 13, 2019, to all known U.S. 
owners and operators of these airplanes. The FAA found that the risk to 
the flying public justified waiving notice and comment prior to 
adoption of this rule because the potential failure of the 9G rigid 
barrier, under certain emergency landing loads, could injure occupants. 
These conditions still exist and the AD is hereby published in the 
Federal Register as an amendment to section 39.13 of the Federal 
Aviation Regulations (14 CFR 39.13) to make it effective to all 
persons. Therefore, the FAA finds good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reasons stated above, the FAA finds that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, the FAA invites you to send any written data, views, 
or arguments about this final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number FAA-2019-
0986 and Product Identifier 2019-NM-201-AD at the beginning of your 
comments. The FAA specifically invites comments on the overall 
regulatory, economic, environmental, and energy aspects of this final 
rule. The FAA will consider all comments received by the closing date 
and may amend this final rule because of those comments.
    The FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide. 
The FAA will also post a report summarizing each substantive verbal 
contact received about this final rule.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 6 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation Programs'' 
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.
