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:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                  Cost on U.S.

                                  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 determining the number of airplanes that might need 
these replacements.

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                   Parts cost
                    Action                                Labor cost               (includes         Cost per
                                                                                   hardware)         product
----------------------------------------------------------------------------------------------------------------
Replacement of the assembly if all parts are   0 work-hours since part is              $10,500          $10,500
 found with corrosion.                          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.

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.
