ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain GROB–WERKE Models G115EG and G120A airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks in the left hand elevator flange. We are issuing this AD to require actions to address the unsafe condition on these products. SUMMARY: This AD is effective June 13, 2014. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of June 13, 2014.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to certain GROB–WERKE Models G115EG and G120A airplanes. That NPRM was published in the Federal Register on February 20, 2014 (79 FR 9661). That NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: An operator of a G 115E aeroplane reported finding a crack during scheduled maintenance on the left hand (LH) elevator flange, part number (P/N) 115E–3761.06. The design of the right hand (RH) elevator flange, P/N 115E–3762.07, is identical. A similar design is used for the elevator flanges installed on G 120A and G–120A–I aeroplanes, P/N 120A–3561.20(A) and P/N 120A–3562.20(A). Therefore, the reported deficiency may also exist on G 120 aeroplanes. This condition, if not detected and corrected, could lead to elevator failure, resulting in reduced control of the aeroplane. To address this potential unsafe condition, GROB Aircraft AG issued Service Bulletins (SB) MSB1078–194 and SB MSB1121–140 to provide instruction for inspection and corrective action. For the reasons described above, this AD requires repetitive inspections of both elevator flanges on an aeroplane to detect any crack, and, depending on findings, replacement of the affected part. You may examine the MCAI on the Internet at https://www.regulations.gov/ #!documentDetail;D=FAA-2014-00920002. ehiers on DSK2VPTVN1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 9661, February 20, 2014) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (79 FR 9661, February 20, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 9661, February 20, 2014). VerDate Mar<15>2010 13:40 May 08, 2014 Jkt 232001 We estimate that this AD will affect 6 products of U.S. registry. We also estimate that it will take about 1 workhour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $510, or $85 per product. In addition, we estimate that any necessary follow-on actions will take about 8 work-hours and require parts costing approximately $306 for the left hand (LH) elevator flange and $365 for the right hand (RH) elevator flange. We estimate a cost of $986 to replace the LH elevator flange per product and $1,045 to replace the RH elevator flange per product. We have no way of determining the number of products that may need these actions. 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 determined that 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 this AD: (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 PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 26611 (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. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0092; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647– 5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to certain GROB-WERKE Models 
G115EG and G120A airplanes. That NPRM was published in the Federal 
Register on February 20, 2014 (79 FR 9661). That NPRM proposed to 
correct an unsafe condition for the specified products and was based on 
mandatory continuing airworthiness information (MCAI) originated by an 
aviation authority of another country. The MCAI states:

    An operator of a G 115E aeroplane reported finding a crack 
during scheduled maintenance on the left hand (LH) elevator flange, 
part number (P/N) 115E-3761.06. The design of the right hand (RH) 
elevator flange, P/N 115E-3762.07, is identical. A similar design is 
used for the elevator flanges installed on G 120A and G-120A-I 
aeroplanes, P/N 120A-3561.20(A) and P/N 120A-3562.20(A). Therefore, 
the reported deficiency may also exist on G 120 aeroplanes.
    This condition, if not detected and corrected, could lead to 
elevator failure, resulting in reduced control of the aeroplane.
    To address this potential unsafe condition, GROB Aircraft AG 
issued Service Bulletins (SB) MSB1078-194 and SB MSB1121-140 to 
provide instruction for inspection and corrective action.
    For the reasons described above, this AD requires repetitive 
inspections of both elevator flanges on an aeroplane to detect any 
crack, and, depending on findings, replacement of the affected part.

You may examine the MCAI on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2014-0092-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 9661, February 20, 
2014) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 9661, February 20, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 9661, February 20, 2014).

Costs of Compliance

    We estimate that this AD will affect 6 products of U.S. registry. 
We also estimate that it will take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $510, or $85 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 8 work-hours and require parts costing approximately $306 
for the left hand (LH) elevator flange and $365 for the right hand (RH) 
elevator flange. We estimate a cost of $986 to replace the LH elevator 
flange per product and $1,045 to replace the RH elevator flange per 
product. We have no way of determining the number of products that may 
need these actions.

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 determined that 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 this AD:
    (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.

reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 AD:

2014-09-11 GROB-WERKE: Amendment 39-17846; Docket No. FAA-2014-0092; 
Directorate Identifier 2014-CE-002-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective June 13, 
2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to GROB-WERKE Model G115EG airplanes, all serial 
numbers, and Model G120A airplanes, serial numbers 85001 through 
85007, 85026 through 85056, and 85058, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 55: Stabilizers.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI

[[Page 26612]]

describes the unsafe condition as cracks in the left hand elevator 
flange. We are issuing this AD to detect and correct cracks in the 
left hand and right hand elevator flanges, which could cause the 
elevator to fail and could result in reduced control.

(f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) through 
(f)(3) of this AD:
    (1) Within the next 30 days after June 13, 2014 (the effective 
date of this AD) and repetitively thereafter at intervals not to 
exceed 100 hours time-in-service (TIS), inspect the left hand (LH) 
and the right hand (RH) elevator flanges, part number (P/N) 115E-
3761.06 and P/N 115E-3762.07 or P/N 120A-3561.20(A) and P/N 120A-
3562.20(A), as applicable, for cracks. Do the inspections following 
GROB Aircraft Service Bulletin No. MSB1078-194/1, dated December 3, 
2013, or GROB Aircraft Service Bulletin No. MSB1121-140, dated 
December 3, 2013, as applicable.
    (2) If any crack is found during any inspection required in 
paragraph (f)(1) of this AD, before further flight, replace the 
affected elevator flange with a serviceable part. Do the replacement 
following GROB Aircraft Service Bulletin No. MSB1078-194/1, dated 
December 3, 2013, or GROB Aircraft Service Bulletin No. MSB1121-140, 
dated December 3, 2013, as applicable.
    (3) As of June 13, 2014 (the effective date of this AD), only 
install an elevator flange P/N 115E-3761.06, P/N 115E-3762.07, P/N 
120A-3561.20(A), or P/N 120A-3562.20(A), if it has been inspected 
following GROB Aircraft Service Bulletin No. MSB1078-194/1, dated 
December 3, 2013, or GROB Aircraft Service Bulletin No. MSB1121-140,
