Discussion In 2015, we were notified of a fatal accident caused by the in-flight structural failure of a wing on a Weatherly Model 620B airplane. The accident investigation found multiple fatigue cracks in the center wing front spar lower hinge bracket. As a result of operator inspections, a cracked hinge bracket in the center wing to outer wing joint was also reported on a different airplane. The hinge bracket from the second report had completely failed, and the airplane was relying on the second failsafe hinge bracket to carry the wing loads. This condition, if not addressed, could result in failure of the wing front spar lower hinge brackets and lead to in-flight separation of the wing with consequent loss of control of the airplane. To correct this unsafe condition, we issued AD 2016–07–11 (81 FR 18461, March 31, 2016) (‘‘AD 2016–07–11’’), which requires a one-time visual inspection of the center and outer wing front spar lower hinge brackets for cracks and corrosion and corrective action as necessary. AD 2016–07–11 also requires sending a report of the inspection results to the FAA. Since we issued AD 2016–07–11, Weatherly has developed improved center wing hinge brackets manufactured from corrosion resistant material. Weatherly also issued new service information for repetitive visual and detailed inspections. Since the cause of the fatigue cracks were attributed to corrosion pits on the accident airplane, we propose to issue this new AD to require those repetitive visual and detailed inspection actions. Related Service Information Under 1 CFR Part 51 We reviewed Weatherly 201/620 Service Bulletin SB–201/620–18001, Revision C, dated May 21, 2018. The service information describes procedures for initial and repetitive inspections of the wing hinge brackets, pins, and wing spar structure for corrosion and/or cracks with repair or replacement as necessary. This service E:\FR\FM\18SEP1.SGM 18SEP1 Federal Register / Vol. 83, No. 181 / Tuesday, September 18, 2018 / Proposed Rules 47117 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. and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. pins, and wing spar structure for corrosion and/or cracks with replacement of parts as necessary. Proposed AD Requirements FAA’s Determination This proposed AD would require repetitive visual and detailed inspections of the wing hinge brackets, We estimate that this proposed AD affects 94 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: We are proposing this AD because we evaluated all the relevant information Costs of Compliance ESTIMATED COSTS Action Labor cost Parts cost Cost per product Detailed inspection for corrosion and cracks with wing removed. Visual inspection for corrosion with bolts and pin caps removed. 50 work-hours × $85 per hour = $4,250 per inspection cycle. 4 work-hours × $85 per hour = $340 per inspection cycle. Not applicable ... $4,250 per inspection cycle .. $399,500 per inspection cycle. Not applicable .. $340 per inspection cycle ..... $31,960 per inspection cycle. We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of Cost on U.S. operators determining the number of airplanes that might need these replacements. ON-CONDITION COSTS Action Labor cost Replacement of the assembly if all parts are found with corrosion. 0 work-hours since part is already removed from airplane. The on-condition costs reflects the cost to replace the entire assembly. The scope of damage found in the required inspection and which specific parts need replaced could vary significantly from airplane to airplane. We have no way of determining how much damage may be found on each airplane or the cost to repair damaged parts on each airplane or the number of airplanes that may require repair. daltland on DSKBBV9HB2PROD with PROPOSALS 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. We are 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 VerDate Sep<11>2014 16:57 Sep 17, 2018 Jkt 244001 products identified in this rulemaking action. This proposed 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 small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated appliances to the Director of the Policy and Innovation Division. Regulatory Findings We 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) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 Parts cost (includes hardware) Cost per product $10,500 $10,500 Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) 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

    In 2015, we were notified of a fatal accident caused by the in-
flight structural failure of a wing on a Weatherly Model 620B airplane. 
The accident investigation found multiple fatigue cracks in the center 
wing front spar lower hinge bracket. As a result of operator 
inspections, a cracked hinge bracket in the center wing to outer wing 
joint was also reported on a different airplane. The hinge bracket from 
the second report had completely failed, and the airplane was relying 
on the second failsafe hinge bracket to carry the wing loads. This 
condition, if not addressed, could result in failure of the wing front 
spar lower hinge brackets and lead to in-flight separation of the wing 
with consequent loss of control of the airplane.
    To correct this unsafe condition, we issued AD 2016-07-11 (81 FR 
18461, March 31, 2016) (``AD 2016-07-11''), which requires a one-time 
visual inspection of the center and outer wing front spar lower hinge 
brackets for cracks and corrosion and corrective action as necessary. 
AD 2016-07-11 also requires sending a report of the inspection results 
to the FAA.
    Since we issued AD 2016-07-11, Weatherly has developed improved 
center wing hinge brackets manufactured from corrosion resistant 
material. Weatherly also issued new service information for repetitive 
visual and detailed inspections. Since the cause of the fatigue cracks 
were attributed to corrosion pits on the accident airplane, we propose 
to issue this new AD to require those repetitive visual and detailed 
inspection actions.

Related Service Information Under 1 CFR Part 51

    We reviewed Weatherly 201/620 Service Bulletin SB-201/620-18001, 
Revision C, dated May 21, 2018. The service information describes 
procedures for initial and repetitive inspections of the wing hinge 
brackets, pins, and wing spar structure for corrosion and/or cracks 
with repair or replacement as necessary. This service

[[Page 47117]]

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

    We are proposing this AD because we evaluated all the relevant 
information and determined 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 repetitive visual and detailed 
inspections of the wing hinge brackets, pins, and wing spar structure 
for corrosion and/or cracks with replacement of parts as necessary.

Costs of Compliance

    We estimate that this proposed AD affects 94 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    The on-condition costs reflects the cost to replace the entire 
assembly. The scope of damage found in the required inspection and 
which specific parts need replaced could vary significantly from 
airplane to airplane. We have no way of determining how much damage may 
be found on each airplane or the cost to repair damaged parts on each 
airplane or the number of airplanes that may require repair.

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.
    We are 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 proposed 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 small airplanes, gliders, balloons, airships, domestic business jet 
transport airplanes, and associated appliances to the Director of the 
Policy and Innovation Division.

Regulatory Findings

    We 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) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Weatherly Aircraft Company: Docket No. FAA-2018-0833; Product 
Identifier 2018-CE-031-AD.

[[Page 47118]]

(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
