We are superseding Airworthiness Directive (AD) 2016-07-24 for all Textron Aviation, Inc. Models 310 through 310R, E310H, E310J, T310P through T310R, 310J-1, 320 through 320F, 320-1, 335, 340, 340A, 401 through 401B, 402 through 402C, 411, 411A, 414, 414A, and 421 through 421C airplanes (type certificates 3A10, 3A25, and A7CE previously held by Cessna Aircraft Company). AD 2016-07-24 required replacement and repetitive inspections of the hardware securing the elevator trim tab push-pull rod. This AD retains the actions for AD 2016-07-24 but revises the repetitive inspection intervals and allows for a longer bolt for the attachment of the elevator trim tab actuator rod end to the push-pull tube connection and/or for the elevator trim tab horn end to the push-pull tube connection. This AD was prompted by comments indicating difficulties with bolt installation and requesting a revision to repetitive inspection intervals to coincide with established inspection intervals. We are issuing this AD to prevent jamming of the elevator trim tab in a position outside the normal limits of travel due to the loss of the attachment hardware connecting the elevator trim tab actuator to the elevator trim tab push-pull rod, which could result in loss of control.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2016-07-24 for 
all Textron Aviation, Inc. Models 310 through 310R, E310H, E310J, T310P 
through T310R, 310J-1, 320 through 320F, 320-1, 335, 340, 340A, 401 
through 401B, 402 through 402C, 411, 411A, 414, 414A, and 421 through 
421C airplanes (type certificates 3A10, 3A25, and A7CE previously held 
by Cessna Aircraft Company). AD 2016-07-24 required replacement and 
repetitive inspections of the hardware securing the elevator trim tab 
push-pull rod. This AD retains the actions for AD 2016-07-24 but 
revises the repetitive inspection intervals and allows for a longer 
bolt for the attachment of the elevator trim tab actuator rod end to 
the push-pull tube connection and/or for the elevator trim tab horn end 
to the push-pull tube connection. This AD was prompted by comments 
indicating difficulties with bolt installation and requesting a 
revision to repetitive inspection intervals to coincide with 
established inspection intervals. We are issuing this AD to prevent 
jamming of the elevator trim tab in a position outside the normal 
limits of travel due to the loss of the attachment hardware connecting 
the elevator trim tab actuator to the elevator trim tab push-pull rod, 
which could result in loss of control.

SUPPLEMENTARY INFORMATION:

Discussion

    On March 30, 2016, we issued AD 2016-07-24, Amendment 39-18469 (81 
FR 21250, April 11, 2016), (``AD 2016-07-24''), for all Textron 
Aviation, Inc. Models 310 through 310R, E310H, E310J, T310P through 
T310R, 310J-1, 320 through 320F, 320-1, 335, 340, 340A, 401 through 
401B, 402 through 402C, 411, 411A, 414, 414A, and 421 through 421C 
airplanes (type certificates 3A10, 3A25, and A7CE previously held by 
Cessna Aircraft Company). AD 2016-07-24 required replacing the hardware 
connecting the elevator trim tab push-pull rod to the elevator trim tab 
actuator and elevator trim tab. AD 2016-07-24 resulted from accident 
reports on Textron Aviation, Inc. Models T310Q, 310Q, and 402B 
airplanes; lessons learned in accident investigation support; and 
analysis of past accidents. The analysis of National Transportation 
Safety Board (NTSB) determination of probable cause indicated that 
following the loss of the attachment hardware connecting the elevator 
trim tab actuator to the elevator trim tab push-pull rod, the elevator 
trim tab may jam in a position outside the normal limits of travel. We 
issued AD 2016-07-24 to require replacement and repetitive inspections 
of the hardware securing the elevator trim tab push-pull rod.

[[Page 58814]]

Actions Since AD 2016-07-24 Was Issued

    Since we issued AD 2016-07-24, we have received reports of 
difficulties in installing the required bolt, part number (P/N) 
NAS464P3-8, because it was found in some cases to be too short to 
properly fasten with a cotter pin as required by the AD. It was also 
determined beneficial to revise the repetitive inspection intervals to 
better coincide with the standard established inspection intervals for 
these airplanes. We are issuing this AD to correct the unsafe condition 
on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed Textron Aviation, Inc. (Cessna Aircraft Company) Multi-
engine Service Bulletin No. MEB-27-02, Revision 1, dated June 15, 2016. 
The service information describes procedures for replacing the hardware 
connecting the elevator trim tab push-pull rod to the elevator trim tab 
actuator and elevator trim tab. This service 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 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 replacement and repetitive inspection of the 
elevator trim tab push-pull rod connecting hardware.

Differences Between the AD and the Service Information

    Due to the immediate safety of flight condition of this AD action, 
we are requiring replacement of the hardware within 90 days after the 
effective date of this AD rather than the potential of up to a year as 
allowed in the service information.
    The kit referenced in the service bulletin contains only standard 
parts that may be procured from other sources.

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 the 
loss of the attachment hardware connecting the elevator trim tab 
actuator to the elevator trim tab push-pull rod may result in jamming 
of the elevator trim tab beyond normal limits, which could result in 
loss of ability to control the airplane. 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. 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-2016-8992 and directorate identifier 2016-CE-021-
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 5,066 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
            Action                    Labor cost               Parts cost             product        operators
----------------------------------------------------------------------------------------------------------------
Elevator trim tab push-pull     5 work-hour x $85 per   $42.....................            $467      $2,365,822
 rod hardware replacement.       hour = $425.
Repetitive Inspection.........  1 work-hour x $85 per   Not applicable..........              85         430,610
                                 hour = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. This is 
the same replacement that is initially required by this AD. We have no 
way of determining the number of aircraft that might need this 
repetitive on-condition replacement:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

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

[[Page 58815]]

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.

List of Subjects in 14 CFR Part 39

reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation 
Regulations (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 removing Airworthiness Directive (AD) 
2016-07-24, Amendment 39-18469 (81 FR 21250, April 11, 2016) and adding 
the following new AD:

2016-17-08 Textron Aviation, Inc.: Amendment 39-18621; Docket No. 
FAA-2016-8992; Directorate Identifier 2016-CE-021-AD.

(a) Effective Date

    This AD is effective September 12, 2016.

(b) Affected ADs

    This AD replaces AD 2016-07-24, Amendment 39-18469 (81 FR 21250, 
April 11, 2016) (``AD 2016-07-24'').

(c) Applicability

    This AD applies to Textron Aviation, Inc. Models 310 through 
310R, E310H, E310J, T310P through T310R, 310J-1, 320 through 320F, 
320-1, 335, 340, 340A, 401 through 401B, 402 through 402C, 411, 
411A, 414, 414A, and 421 through 421C airplanes (type certificates 
3A10, 3A25, and A7CE previously held by Cessna Aircraft Company), 
all serial numbers, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 2731, Elevator Tab Control System.

(e) Unsafe Condition

    This AD supersedes AD 2016-07-24, which required replacement and 
repetitive inspections of the hardware securing the elevator trim 
tab push-pull rod. This AD retains the actions for AD 2016-07-24 but 
revises the repetitive inspection intervals and allows for a longer 
bolt for the attachment of the elevator trim tab actuator rod end to 
the push-pull tube connection and/or for the elevator trim tab horn 
end to the push-pull tube connection. This AD was prompted by 
comments indicating difficulties with bolt installation and 
requesting a revision to repetitive inspection intervals to coincide 
with established inspection intervals. We are issuing this AD to 
prevent jamming of the elevator trim tab in a position outside the 
normal limits of travel due to the loss of the attachment hardware 
connecting the elevator trim tab actuator to the elevator trim tab 
push-pull rod, which could result in loss of control.
