Airworthiness Directives; Textron Aviation Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-15-
06, which applies to certain Textron Aviation Inc. Models 175 and 175A 
airplanes (type certificate previously held by Cessna Aircraft 
Company). AD 2008-15-06 currently requires checking the airplane 
logbook to determine if the original engine mounting brackets have been 
replaced. If the original engine mounting brackets are still installed, 
the AD requires repetitively inspecting those brackets for cracks and 
replacing any cracked engine mounting bracket until all four original 
engine mounting brackets are replaced. Replacing all four original 
engine mounting brackets terminates the actions required in AD 2008-15-
06. Since we issued AD 2008-15-06, we have determined that the 
applicability needs to be changed to add a serial number and take one 
out. This proposed AD would retain the actions required in AD 2008-15-
06 and would change the Applicability section. We are proposing this AD 
to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by May 27, 2016.

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2016-5579; 
Directorate Identifier 2016-CE-010-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed 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 proposed AD.

Discussion

    On July 15, 2008, we issued AD 2008-15-06, Amendment 39-15618 (73 
FR 43845, July 29, 2008), (``AD 2008-15-06''), for certain Textron 
Aviation Inc. Models 175 and 175A airplanes (type certificate 
previously held by Cessna Aircraft Company). AD 2008-15-06 requires you 
to check the airplane logbook to determine if the original engine 
mounting brackets have been replaced. If the original engine mounting 
brackets are still installed, this AD requires you to repetitively 
inspect those brackets for cracks and replace any cracked engine 
mounting bracket. After replacing all four original engine mounting 
brackets, no further action will be required by this AD. AD 2008-15-06 
resulted from a report of the engine detaching from the firewall on a 
Cessna Model 175 airplane during landing. We issued AD 2008-15-06 to 
detect and correct cracks in the engine

[[Page 21502]]

mounting brackets, which could result in failure of the engine mounting 
bracket. This failure could lead to the engine detaching from the 
firewall.

Actions Since AD 2008-15-06 Was Issued

    Since we issued AD 2008-15-06, we have determined that the 
applicability for Model 175A airplanes needs to be changed. We have 
determined that a serial number has been inadvertently included in the 
applicability and a serial number has been inadvertently omitted from 
the applicability.

Related Service Information Under 1 CFR Part 51

    We reviewed Cessna Single Engine Service Bulletin SEB07-2, Revision 
2, dated June 18, 2007. The service information describes procedures 
for inspecting the upper and lower engine mounting brackets on both the 
left and right sides for cracks and replacing cracked engine mounting 
brackets. 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 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 retain the requirements of AD 2008-15-06 and 
would add a serial number to the applicability and take one out.

Costs of Compliance

    We estimate that this AD would affect 1,218 airplanes in the U.S. 
registry.
    We estimate the following costs to do each proposed inspection:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                  Labor cost                              Parts cost                airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
7.5 work-hours x $80 per hour = $600.........  Not applicable.................            $600         $730,800
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary proposed 
replacements:

------------------------------------------------------------------------
                                                        Total cost per
           Labor cost                 Parts cost           airplane
------------------------------------------------------------------------
3 work-hours per bracket x $80    $200 per bracket.   $440 per bracket.
 per hour = $240 per bracket. 4    4 x $200 = $800     $1,760 to replace
 brackets per airplane x $240      for all 4           all 4 brackets.
 per bracket = $960.               brackets.
------------------------------------------------------------------------

    There is no estimated cost of compliance difference between this 
proposed AD and AD 2008-15-06 since there is no change in the number of 
affected airplanes or in the proposed actions. The cost impact on the 
public would be in the removal of serial number 691 and the addition of 
serial number 619.

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

    We have 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 that the 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.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 71, Power Plant.

(e) Unsafe Condition

    This AD was prompted by the determination that an airplane needs 
to be added to the Applicability section and an airplane needs to be 
removed from the Applicability section. We are issuing this AD to 
detect and correct cracks in the engine mounting brackets, which 
could result in failure of the engine mounting bracket. This failure 
could lead to the engine detaching from the firewall.

(f) Compliance

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

(g) Airplane Logbook Check

    (1) Check the airplane logbook to determine if all four of the 
original engine mounting brackets have been replaced. Do the logbook 
check at the following compliance time, as applicable. The owner/
operator holding at least a private pilot certificate as authorized 
by section 43.7 may do this action.
    (i) For airplanes previously affected by AD 2008-15-06: Within 
the next 30 days after September 2, 2008 (the effective date 
retained from AD 2008-15-06).
    (ii) For the new airplane affected by this AD: Within the next 
30 days after the effective date of this AD.
    (2) If you can positively determine that all four of the 
original engine mounting brackets have been replaced, no further 
action is required. Make an entry into the aircraft logbook showing 
compliance with this portion of the AD in accordance with 14 CFR 
43.9. The owner/operator holding at least a private pilot 
certificate as authorized by section 43.7 may do this action.
    (3) If you cannot positively determine that all four of the 
original engine mounting brackets have been replaced, inspect each 
of the upper and lower engine mounting brackets on both the left and 
right sides for cracks following Cessna Single Engine Service 
Bulletin SEB07-2, Revision 2, dated June 18, 2007. Do the 
inspections at the following compliance times, as applicable.
    (i) For airplanes previous affected by AD 2008-15-06: Initially 
inspect within the next 12 months after September 2, 2008 (the 
effective date retained from AD 2008-15-06). If no cracks are found, 
repetitively inspect thereafter at intervals not to exceed 500 hours 
time-in-service (TIS) until all four of the original engine mounting 
brackets are replaced.
    (ii) For the new airplane affected by this AD: Initially inspect 
within the next 12 months after the effective date of this AD. If no 
cracks are found, repetitively inspect thereafter at intervals not 
to exceed 500 hours TIS until all four of the original engine 
mounting brackets are replaced.

(h) Engine Mounting Bracket Replacement

    For all airplanes affected by this AD: If cracks are found in 
any of the engine mounting brackets during any inspection required 
in paragraph (g)(3) of this AD, including all subparagraphs, before 
further flight after the inspection in which cracks are found, 
replace the cracked engine mounting bracket(s) following Cessna 
Single Engine Service Bulletin SEB07-2, Revision 2, dated June 18, 
2007. Replacing the cracked engine mounting bracket terminates the 
repetitive inspections required in paragraphs (g)(3)(i) and 
(g)(3)(ii) of this AD only for the replaced engine mounting bracket.

(i) Terminating Action

    To terminate the repetitive inspections required in paragraphs 
(g)(3)(i) and (g)(3)(ii) of this AD, you may replace all four 
original engine mounting brackets following Cessna Single Engine 
Service Bulletin SEB07-2, Revision 2, dated June 18, 2007, at the 
following compliance times, as applicable.
    (1) For airplanes previous affected by AD 2008-15-06: At any 
time before or after the initial inspection required in paragraph 
(g)(3)(i) of this AD.
    (2) For the new airplane affected by this AD: At any time before 
or after the initial inspection required in paragraph (g)(3)(ii) of 
this AD.

(j) Engine Mounting Bracket Disposal

    For all airplanes affected by this AD: Before further flight 
after the engine mounting bracket is removed for replacement, 
dispose of every replaced bracket following 14 CFR 43.10, paragraph 
(c)(6), which states the following: ``Mutilation. The part may be 
mutilated to deter its installation in a type certificated product. 
The mutilation must render the part beyond repair and incapable of 
being reworked to appear to be airworthy.''

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Wichita Aircraft Certification Office (ACO), 
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 ACO, send it to the 
attention of the person identified in paragraph (l) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) AMOCs approved for AD 2008-15-06 are approved as AMOCs for 
the corresponding provisions of this AD.
