SUPPLEMENTARY INFORMATION: address the unsafe condition identified in this AD. Discussion An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because failure of the wing front spar lower hinge fitting could cause the wing to separate from the airplane and cause loss of control. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Recently, a Weatherly Aircraft Company Model 620B airplane crashed while conducting agricultural operations. Preliminary investigation indicates presence of fatigue cracks in the center wing front spar lower hinge fitting of the accident aircraft. As a result of voluntary operator inspections, an additional cracked fitting in the center wing joint was recently reported. Investigation reveals that the cracks resulted from fatigue damage on the hinge fitting and that routine maintenance practices are not finding this damage. This condition, if not detected and corrected, could result in failure of the wing front spar lower hinge fittings, which could cause the wing to separate and cause loss of control. We are issuing this AD to correct the unsafe condition on these products. FAA’s Determination We are issuing 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. AD Requirements This AD requires visually inspecting the center and outer wing front spar lower hinge fittings for cracks and corrosion and taking all necessary corrective actions. This AD also requires sending the inspection results to the FAA. Based on the reports received from the AD requirements, we will work with the type certificate holder to evaluate that information to determine whether repetitive inspections are necessary and/or a possible terminating action. Based on this evaluation, we may initiate further rulemaking action to FAA’s Justification and Determination of the Effective Date Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2016–5422 and Directorate Identifier 2016–CE–011–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 95 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action jstallworth on DSK7TPTVN1PROD with RULES Visually inspect the center and outer wing front spar lower hinge fitting.

SUPPLEMENTARY INFORMATION: 

Discussion

    Recently, a Weatherly Aircraft Company Model 620B airplane crashed 
while conducting agricultural operations. Preliminary investigation 
indicates presence of fatigue cracks in the center wing front spar 
lower hinge fitting of the accident aircraft. As a result of voluntary 
operator inspections, an additional cracked fitting in the center wing 
joint was recently reported.
    Investigation reveals that the cracks resulted from fatigue damage 
on the hinge fitting and that routine maintenance practices are not 
finding this damage. This condition, if not detected and corrected, 
could result in failure of the wing front spar lower hinge fittings, 
which could cause the wing to separate and cause loss of control. We 
are issuing this AD to correct the unsafe condition on these products.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires visually inspecting the center and outer wing 
front spar lower hinge fittings for cracks and corrosion and taking all 
necessary corrective actions. This AD also requires sending the 
inspection results to the FAA.
    Based on the reports received from the AD requirements, we will 
work with the type certificate holder to evaluate that information to 
determine whether repetitive inspections are necessary and/or a 
possible terminating action. Based on this evaluation, we may initiate 
further rulemaking action to address the unsafe condition identified in 
this AD.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
failure of the wing front spar lower hinge fitting could cause the wing 
to separate from the airplane and cause loss of control. Therefore, we 
find that notice and opportunity for prior public comment are 
impracticable and that good cause exists for making this amendment 
effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2016-5422 and 
Directorate Identifier 2016-CE-011-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 95 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

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.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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) Is not a ``significant rule'' under 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.

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection

    Within the next 30 days after April 15, 2016 (the effective date 
of this AD), do a close visual inspection of the center and outer 
wing front spar lower hinge fittings for cracks and corrosion. Prior 
to the inspection do the following:
    (1) Remove the left and right center wing to outer wing joint 
covers from the airplane.
    (2) Remove the lower forward wing hinge pin bolt caps.

(h) Replacement

    If any cracks are found during the inspection required in 
paragraph (g) of this AD, before further flight, replace the cracked 
wing front spar lower hinge fitting with an airworthy part.

(i) Repair

    If any corrosion is found during the inspection required in 
paragraph (g) of this AD, before further flight, remove up to .020 
inches of the wing front spar lower hinge fitting material in any 
direction to repair corrosion. Replace any parts requiring removal 
of more than .020-inch of wing front spar lower hinge fitting. Any 
operator may request an alternative to the replacement requirement 
using the procedures found in 14 CFR 39.19 and paragraph (m) of this 
AD.
