(a) Comments Due Date 
We must receive comments by November 
2, 2018. 
(b) Affected ADs 
None. 
(c) Applicability 
This AD applies to Weatherly Aircraft 
Company (Weatherly) Models 201, 201A, 
201B, 201C, 620, 620A, 620B, 620B–TG, and 620TP airplanes, all serial numbers, certificated in any category. 
(d) Subject 
Joint Aircraft System Component (JASC)/ 
Air Transport Association (ATA) of America 
Code 5740, Wing Attach Hinge Fitting. 
(e) Unsafe Condition 
This AD was prompted by reports of cracks 
found on the center wing front spar lower 
hinge bracket. We are issuing this AD to detect and correct corrosion and cracks on the wing hinge brackets and pin assemblies. The unsafe condition, if not addressed, could result in failure of the wing front and rear spar lower hinge brackets and lead to in- flight separation of the wing with consequent loss of control of the airplane. 
(f) Compliance 
Comply with this AD within the 
compliance times specified, unless already 
done. 
(g) Detailed Inspection 
(1) Within 3 months after the effective date 
of this AD and thereafter at intervals not to 
exceed 5 years, inspect each center and outer wing spar and spar cap, wing hinge bracket, and hardware for corrosion and cracks by following paragraphs 7 through 22 under the Detailed Inspection section in Weatherly 201/620 Service Bulletin SB–201/620–18001, Revision C, dated May 21, 2018 (Weatherly SB–201/620–18001, Revision C), except this AD does not require you to contact Weatherly. 
(2) Serial numbers (S/N) 1155 and 1558 
have already had the initial detailed inspection required by paragraph (g)(1) of this AD and only the 5-year repetitive detailed inspections are required for these airplanes. 
(3) If any corrosion or cracking is found 
during any of the inspections required in paragraph (g)(1) of this AD, before further flight, repair or replace any parts with corrosion and cracking as specified in paragraphs 7 through 13 under the Detailed Inspection section in Weatherly SB–201/620– 18001, Revision C. 
(h) Visual Inspection 
Within 12 months after the initial detailed 
inspection required in paragraph (g) of this 
AD and thereafter at intervals not to exceed 12 months, visually inspect each forward and rear wing hinge bracket attachment pins, bolts, removed caps, spacers, and hardware for corrosion by following paragraphs 4 through 7 under the Visual Inspection section in Weatherly SB–201/620–18001, Revision C. If any corrosion is found during any of the inspections required by this paragraph, before further flight, inspect further, repair, and/or replace any parts with 
corrosion as specified in paragraphs 5 and 6 under the Visual Inspection section in Weatherly SB–201/620–18001, Revision C. You may perform a detailed inspection in accordance with paragraph (g) of this AD instead of any visual inspection required by paragraph (h) of this AD. 
(i) Alternative Methods of Compliance 
(AMOCs) 
(1) The Manager, Los Angeles ACO Branch, 
FAA, has the authority to approve AMOCs 
for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the manager of the certification office, send it to the attention of the person identified in paragraph (j) of this AD. 
(2) Before using any approved AMOC,

Each experimental product during a market test is identified on the applicable product list under the organizational group heading ‘‘Market Tests’’ in accordance with 39 U.S.C. 3641(b)(3) and existing §§ 3020.4(b)(2)(ii)(D) and 3020.4(b)(3)(ii)(D) of this chapter. The intent of existing § 3035.18 and the revisions proposed in this order apply only to a request to offer a proposed product or price category in non-experimental status, that is— subject to the applicable requirements of 39 U.S.C. 3622, 3633, or 3642, and the applicable regulations promulgated thereunder.

II. Proposed Amendments III. Section-by-Section Analysis IV. Administrative Actions V. Ordering Paragraphs 
I. Introduction 
Pursuant to 39 U.S.C. 503 and 3641, 
this order establishes a rulemaking 
docket that proposes amendments to the Commission’s regulations governing market tests of experimental products appearing in existing 39 CFR part 3035. The proposed amendments would revise regulations concerning market test revenue limitations and requests to add a non-experimental product or price category based on an experimental product to the market dominant or 
competitive product list.
1The proposed 
rules reflect lessons learned through the Commission’s experiences with the existing regulations and current practice before the Commission. The proposed rules appear after the signature of this order in Attachment A. 
II. Proposed Amendments 
Section 3641 of title 39 of the United 
States Code authorizes the Postal 
Service to conduct market tests of experimental products. In accordance with its specific authority to regulate market tests under 39 U.S.C. 3641 and its general authority under 39 U.S.C. 503 to promulgate regulations and establish procedures, the Commission codified existing 39 CFR part 3035 to establish procedures for conducting 
market tests of experimental products.
2 
The Commission establishes this proceeding to consider amendments to the existing market test regulations. 
The proposed amendments are 
discussed below. The first set of amendments intend to revise the method for calculating applicable revenue limitations for market tests appearing in existing §§ 3035.15 and 3035.16 to be consistent with the current level of precision used in calculating the annual limitation on the percentage change in rates for market dominant products (price cap). The second set of proposed amendments aim to clarify the process under existing § 3035.18 for adding a non-experimental product or price category based on an experimental product to the market dominant or competitive product list and to emphasize the necessity of receiving specific detailed information in those instances. 
A. Market Test Revenue Limitations 
Unless the Commission grants an 
exemption, total revenues anticipated or 
in fact received by the Postal Service from an experimental product must not exceed $10 million in any year. 39 U.S.C. 3641(e)(1). Upon written application of the Postal Service, the Commission may exempt the market test from the $10 million revenue limitation if certain requirements are met. 39 U.S.C. 3641(e)(2). If the Commission grants an exemption, total revenues anticipated, or in fact received by, the Postal Service from a market test may not exceed $50 million in any year. Id. These amounts must be adjusted annually by the change in the Consumer Price Index for such year, as determined under the regulations of the Commission. 39 U.S.C. 3641(g). Existing § 3035.15(a) uses the Consumer Price Index—All Urban Customers (CPI–U index), as specified by §§ 3010.21(a) and 3010.22(a) of this chapter, to calculate these amounts. 
Existing § 3035.15(d) explains the 
method for calculating the $10 million revenue limitation on a fiscal year basis, as adjusted for the change in the CPI– U index ($10 Million Adjusted Limitation). Calculating the $10 Million Adjusted Limitation involves three steps. First, a simple average CPI–U index was calculated for Fiscal Year 2008 by summing the monthly CPI–U values from October 2007 through September 2008 and dividing the sum by 12. 39 CFR 3035.15(d); see 39 U.S.C. 
3641(g). The result is a Base Average of 214.5. 39 CFR 3035.15(d). Second, a second simple average CPI–U index is calculated for each subsequent fiscal year by summing the 12 monthly CPI– U values for the previous fiscal year and dividing the sum by 12 to obtain a Recent Average. Id. Third, the revenue 
limitation for the current fiscal year is calculated by multiplying $10 million by the Recent Average divided by the Base Average of 214.5. Id. The result is 
the $10 Million Adjusted Limitation, rounded to the nearest dollar. Id. Existing § 3035.16(c) sets forth corresponding steps for calculating the $50 million revenue limitation, as adjusted for the change in the CPI–U index ($50 Million Adjusted Limitation). 
Under existing §§ 3035.15 and 
3035.16, the Base Average for both the $10 Million and $50 Million Adjusted Limitations is calculated using one decimal place (214.5). In Order No. 303, the Commission amended the price cap rules appearing in §§ 3010.21 and 3010.22 of this chapter to calculate the CPI–U price cap using three decimal places instead of one.
