When at least 75 percent of the plants are in bloom and there is no more than 15 percent seed set, 200 plants shall be examined to determine the pollen production index (PPI). Each plant is rated as 1, 2, 3 or 4 with ‘‘1’’ representing no pollen, ‘‘2’’ representing a trace of pollen, ‘‘3’’ representing substantially less than normal pollen, and ‘‘4’’ representing normal pollen. The rating is weighted as 0, 0.1, 0.6 or 1.0, respectively. The total number of plants of each rating is multiplied by the weighted rating and the values are totaled. The total is divided by the number of plants rated and multiplied by 100 to determine the PPI. For hybrid production using separate male and female rows, the maximum PPI allowed for 95 percent hybrid seed is 14 for the Foundation class, and 6 for the F1 hybrid. For hybrid production using comingled parent lines, the maximum PPI allowed for 75 percent hybrid Certified class seed is 25, with an allowance for blending to reach a PPI of 25 for fields with a PPI above 25, but no greater than 30.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Bell Model 214ST helicopters with certain serial-numbered spindle to yoke bolts (bolts) part number (P/N) 214–010–262–103 installed. The NPRM published in the Federal Register on February 26, 2020 (85 FR 11003). The NPRM was prompted by the discovery of bolts with nonconforming external thread root radii. The NPRM proposed to require removing the affected bolts from service and would prohibit installing an affected bolt on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products. Since the FAA issued the NPRM, Bell Helicopter Textron Inc., changed its name to Bell Textron Inc. This AD reflects that change and updates the contact information. jbell on DSKJLSW7X2PROD with RULES Comments After the NPRM was published, the FAA received comments from the European Union Aviation Safety Agency (EASA). The following presents the comments received on the NPRM and the FAA’s response to the comments. Request for the FAA To Change the Applicability Request: EASA requested that the FAA revise the applicability of the AD to include all helicopters for which the affected P/N and S/N bolts are eligible for installation. EASA stated this revision should be made in order to fully prohibit (re)installation of the affected bolt on any (other) helicopter. EASA further stated that the NPRM’s applicability paragraph ‘‘excludes all helicopters that have another P/N [bolt] installed, or the same P/N but another S/N installed, but for which installation of that P/N (and any S/N thereof) is likely eligible. Since the AD does not apply to those helicopters, none of the requirements of the AD would apply either.’’ According to EASA, the prohibition in paragraph (g)(2) of the NPRM, which prohibits the installation on any helicopter of a bolt with a P/N and S/N listed in the applicability of the AD, could be legally disregarded by VerDate Sep<11>2014 16:03 Jul 06, 2020 Jkt 250001 operators of helicopters that are outside the scope of the applicability of the AD. FAA Response: The FAA disagrees. Upon installation of a bolt with a P/N and S/N listed in the applicability, the AD applies to that helicopter, and the required actions of the AD must be complied with prior to approving the helicopter for return to service. These required actions include the installation prohibition in paragraph (e)(2) of the AD. Thus, the AD prohibits the installation of an affected bolt on any Bell Model 214ST helicopters after the effective date of the AD. FAA’s Determination The FAA has reviewed the relevant information, considered the comments received, and determined that an unsafe condition exists and is likely to exist or develop on other products of the same type design and that air safety and the public interest require adopting the AD requirements as proposed with the changes described previously. These changes are consistent with the intent proposed in the NPRM for correcting the unsafe condition and will neither increase the economic burden on any operator nor increase the scope of the AD. Related Service Information The FAA reviewed Bell Helicopter Textron Alert Service Bulletin 214ST– 18–93 Revision A, dated April 17, 2019, for Model 214ST helicopters. This service information specifies inspecting the historical records and spare parts to determine the S/N of each bolt. If the S/ N of the bolt indicates it is a nonconforming bolt, the service information specifies torque checking the bolt every 25 hours until the bolt reaches its life limit. Differences Between This AD and the Service Information The service information specifies torque checking the bolt every 25 hours until it is replaced upon reaching its life limit, while this AD requires removing each bolt from service within 25 hours time-in-service. Costs of Compliance The FAA estimates that this AD affects 16 helicopters of U.S. registry. The FAA estimates that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Replacing 1 bolt takes about 8 workhours and parts cost about $7,073 for an estimated replacement cost of $7,753 per helicopter. PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 40585 The FAA has no way of determining the number of bolts that might need to be replaced. According to the manufacturer, some of the costs of this 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 AD would not have federalism implications under Executive Order 13132. This 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (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.
