A refining process is validated through analytical testing that meets the standards described in paragraph (c) of 7 CFR 66.9. Paragraph (c) requires that analytical testing meet the following standard: (1) Laboratory quality assurance must ensure the validity and reliability of test results; (2) analytical method selection, validation, and verification must ensure that the testing method used is appropriate (fit for purpose) and that the laboratory can successfully perform the testing; (3) the demonstration of testing validity must ensure consistent accurate analytical performance; and (4) method performance specifications must ensure analytical tests are sufficiently sensitive for the purposes of the detectability requirements of this part. In the preamble to the final regulations, USDA indicated it would provide instructions to the industry to explain how they can ensure acceptable validation of refining processes in accordance with AMS standards (83 FR 65843). A draft of those instructions is now available on the AMS bioengineered food disclosure website at https://www.ams.usda.gov/rulesregulations/be. With this notice, AMS is seeking comments on these draft instructions. USDA will provide further instructions on testing method selection at a later date. At this time, we are only seeking feedback on the validation instructions referenced in this notice. Any comments not directly related to these draft instructions will not be considered. After reviewing the comments on these draft instructions, AMS will publish final instructions on its website. The final instructions will be maintained and available on the AMS website. These final instructions pertain to the requirements of the existing regulations, which can be found at https://www.federalregister.gov/ documents/2018/12/21/2018-27283/ national-bioengineered-food-disclosurestandard. jbell on DSKJLSW7X2PROD with PROPOSALS Authority: 7 U.S.C. 1639.

Discussion The FAA proposes to adopt a new AD for Robinson Helicopter Company Model R44 and R44 II helicopters with an agricultural spray system installed by STC SR00286BO with spray systems serial-numbered 0045 through 0178 inclusive. STC SR00286BO approves the installation of a Simplex spray system. This proposed AD would require a repetitive inspection until the pump fitting is modified. This proposed AD is prompted by a report of an in-flight failure of the spray system pump fitting. Following the issuance of a Simplex service letter, five E:\FR\FM\17DEP1.SGM 17DEP1 68818 Federal Register / Vol. 84, No. 242 / Tuesday, December 17, 2019 / Proposed Rules additional reports of failed fittings were received. Failure of the pump fitting causes uncontrolled discharge of the spray liquid exiting the system pump. The pump output port is in direct alignment with the engine air intake, allowing the engine to ingest the spray liquid. This condition, if not addressed, could result in an in-flight engine shutdown. Related Service Information Under 1 CFR Part 51 The FAA reviewed the following service information: • Simplex Mfg Alert Service Bulletin ASB2017–001, Initial Release, dated March 28, 2017. This service information describes procedures for inspecting the spray system pump fitting to detect damage, including signs of stress, cracking, fatigue, and evidence of leaking. • Simplex Mfg Service Letter SL2017–017, Revision B, dated March 14, 2018. This service information describes procedures for replacing the spray system pump fitting with an improved pump fitting and installing hose supports. • Simplex Mfg Service Letter SL2017–030, Initial Release, dated March 12, 2018. This service information describes procedures for installing a pump outlet cover. 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. jbell on DSKJLSW7X2PROD with PROPOSALS Other Related Service Information The FAA reviewed Simplex Mfg, Installation Manual, Simplex Manufacturing Co. HPR44 III Spray System for the Robinson R44 Series Helicopter, Installation Manual PM001– HPR44III–25–008, Revision 7, dated May 2, 2017. This service information specifies unpacking, installation, and system function test procedures. The FAA also reviewed Simplex Mfg, Instructions for Continued Airworthiness (ICA), Simplex Manufacturing Co. HPR44 III Spray System for the Robinson R44 Series Helicopter, PM011–HPR44III–25–007 ICA, Revision 9, dated April 20, 2018. This service information specifies general, airworthiness limitation, inspection and maintenance, dimension and access, lifting and shoring, leveling and weighing, towing and taxiing, storing, placard and marking, servicing and lubricating, standard practice, and equipment and furnishing information. VerDate Sep<11>2014 16:54 Dec 16, 2019 Jkt 250001 FAA’s Determination The FAA is proposing this AD after evaluating all the relevant information and determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require, before each flight, visually inspecting the spray system pump fitting for signs of stress, cracking, fatigue, and evidence of leaking. If there is any sign of stress, cracking, fatigue, or evidence of leaking, this proposed AD would require replacing pump fitting P/N P–58–0752– 40 with pump fitting P/N 000-123847-000, and installing cushion clamp P/N 000–115571–000, cable tie hose supports, and pump outlet cover P/N 244–302056–001 before further flight. If there is no sign of stress, cracking, fatigue, or evidence of leaking, this proposed AD would require replacing the pump fitting with fitting P/N 000-123847-000, and installing cushion clamp P/N 000–115571–000, cable tie hose supports, and pump outlet cover P/N 244–302056–001 within 3 months. This proposed AD would also require pressurizing and inspecting the spray system with fitting P/N 000-123847-000, the cushion clamp, the cable tie hose supports, and the pump outlet cover installed, and depending on the outcome of this inspection, replacing the parts and repeating the inspection again. Differences Between This Proposed AD and the Service Information The Simplex Mfg alert service bulletin and service letter service information identify the spray system as the R44III spray system. The Simplex Mfg installation manual and ICA service information identify the spray system as the HPR44 III spray system. However, this proposed AD identifies this modification as an agricultural spray system installed by STC SR00286BO and acknowledges the marketing designation of Simplex Model 244 spray system. The Simplex Mfg alert service bulletin service information specifies contacting Simplex if there is evidence of damage. This proposed AD would instead require replacing the spray system pump fitting, and installing a cushion clamp, cable tie hose supports, and a pump outlet cover if there is any sign of stress, cracking, fatigue, or evidence of leaking. Costs of Compliance The FAA estimates that this proposed AD affects 75 helicopters of U.S. registry. Labor costs are estimated at $85 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this proposed AD. Inspecting the fitting would take about 0.1 work-hour for an estimated cost of $9 per helicopter and $675 for the U.S. fleet per inspection cycle. Replacing the fitting and installing the cushion clamp and hose supports would take about 1 work-hour with a nominal parts costs for an estimated cost of $85 per helicopter and $6,375 for the U.S. fleet. Installing the pump outlet cover would take about 1 work-hour and parts would cost about $300 for an estimated cost of $385 per helicopter and $28,875 for the U.S. fleet. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, all costs are included in this cost estimate. 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. Regulatory Findings The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and E:\FR\FM\17DEP1.SGM 17DEP1 Federal Register / Vol. 84, No. 242 / Tuesday, December 17, 2019 / Proposed Rules (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Discussion

    The FAA proposes to adopt a new AD for Robinson Helicopter Company 
Model R44 and R44 II helicopters with an agricultural spray system 
installed by STC SR00286BO with spray systems serial-numbered 0045 
through 0178 inclusive. STC SR00286BO approves the installation of a 
Simplex spray system. This proposed AD would require a repetitive 
inspection until the pump fitting is modified.
    This proposed AD is prompted by a report of an in-flight failure of 
the spray system pump fitting. Following the issuance of a Simplex 
service letter, five

[[Page 68818]]

additional reports of failed fittings were received. Failure of the 
pump fitting causes uncontrolled discharge of the spray liquid exiting 
the system pump. The pump output port is in direct alignment with the 
engine air intake, allowing the engine to ingest the spray liquid. This 
condition, if not addressed, could result in an in-flight engine 
shutdown.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed the following service information:
     Simplex Mfg Alert Service Bulletin ASB2017-001, Initial 
Release, dated March 28, 2017. This service information describes 
procedures for inspecting the spray system pump fitting to detect 
damage, including signs of stress, cracking, fatigue, and evidence of 
leaking.
     Simplex Mfg Service Letter SL2017-017, Revision B, dated 
March 14, 2018. This service information describes procedures for 
replacing the spray system pump fitting with an improved pump fitting 
and installing hose supports.
     Simplex Mfg Service Letter SL2017-030, Initial Release, 
dated March 12, 2018. This service information describes procedures for 
installing a pump outlet cover.
    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.

Other Related Service Information

    The FAA reviewed Simplex Mfg, Installation Manual, Simplex 
Manufacturing Co. HPR44 III Spray System for the Robinson R44 Series 
Helicopter, Installation Manual PM001-HPR44III-25-008, Revision 7, 
dated May 2, 2017. This service information specifies unpacking, 
installation, and system function test procedures.
    The FAA also reviewed Simplex Mfg, Instructions for Continued 
Airworthiness (ICA), Simplex Manufacturing Co. HPR44 III Spray System 
for the Robinson R44 Series Helicopter, PM011-HPR44III-25-007 ICA, 
Revision 9, dated April 20, 2018. This service information specifies 
general, airworthiness limitation, inspection and maintenance, 
dimension and access, lifting and shoring, leveling and weighing, 
towing and taxiing, storing, placard and marking, servicing and 
lubricating, standard practice, and equipment and furnishing 
information.

FAA's Determination

    The FAA is proposing this AD after evaluating all the relevant 
information and determining that the unsafe condition described 
previously is likely to exist or develop in other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require, before each flight, visually 
inspecting the spray system pump fitting for signs of stress, cracking, 
fatigue, and evidence of leaking. If there is any sign of stress, 
cracking, fatigue, or evidence of leaking, this proposed AD would 
require replacing pump fitting P/N P-58-0752-40 with pump fitting P/N 
000[hyphen]123847[hyphen]000, and installing cushion clamp P/N 000-
115571-000, cable tie hose supports, and pump outlet cover P/N 244-
302056-001 before further flight. If there is no sign of stress, 
cracking, fatigue, or evidence of leaking, this proposed AD would 
require replacing the pump fitting with fitting P/N 
000[hyphen]123847[hyphen]000, and installing cushion clamp P/N 000-
115571-000, cable tie hose supports, and pump outlet cover P/N 244-
302056-001 within 3 months. This proposed AD would also require 
pressurizing and inspecting the spray system with fitting P/N 
000[hyphen]123847[hyphen]000, the cushion clamp, the cable tie hose 
supports, and the pump outlet cover installed, and depending on the 
outcome of this inspection, replacing the parts and repeating the 
inspection again.

Differences Between This Proposed AD and the Service Information

    The Simplex Mfg alert service bulletin and service letter service 
information identify the spray system as the R44III spray system. The 
Simplex Mfg installation manual and ICA service information identify 
the spray system as the HPR44 III spray system. However, this proposed 
AD identifies this modification as an agricultural spray system 
installed by STC SR00286BO and acknowledges the marketing designation 
of Simplex Model 244 spray system. The Simplex Mfg alert service 
bulletin service information specifies contacting Simplex if there is 
evidence of damage. This proposed AD would instead require replacing 
the spray system pump fitting, and installing a cushion clamp, cable 
tie hose supports, and a pump outlet cover if there is any sign of 
stress, cracking, fatigue, or evidence of leaking.

Costs of Compliance

    The FAA estimates that this proposed AD affects 75 helicopters of 
U.S. registry. Labor costs are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this proposed AD.
    Inspecting the fitting would take about 0.1 work-hour for an 
estimated cost of $9 per helicopter and $675 for the U.S. fleet per 
inspection cycle. Replacing the fitting and installing the cushion 
clamp and hose supports would take about 1 work-hour with a nominal 
parts costs for an estimated cost of $85 per helicopter and $6,375 for 
the U.S. fleet. Installing the pump outlet cover would take about 1 
work-hour and parts would cost about $300 for an estimated cost of $385 
per helicopter and $28,875 for the U.S. fleet.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, all costs are included in this cost 
estimate.

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.

Regulatory Findings

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and

[[Page 68819]]

    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Robinson Helicopter Company: Docket No. FAA-2019-1053; Product 
Identifier 2018-SW-037-AD.

(a) Comments Due Date

    The FAA must receive comments by January 31, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Robinson Helicopter Company Model R44 and R44 
II helicopters, certificated in any category, with an agricultural 
spray system installed by Supplemental Type Certificate (STC) 
SR00286BO with spray systems serial-numbered 0045 through 0178 
inclusive, installed.
    Note 1 to paragraph (c) of this AD: STC SR00286BO approves the
