RIN 2120-AA64

Airworthiness Directives; GROB-WERKE Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
GROB-WERKE Model G115EG airplanes. This proposed AD results from 
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 describes the unsafe 
condition as cracks in the elevator trim tab arms on several Grob G 115 
airplanes, which could result in failure of the part and consequent 
loss of control. We are issuing this proposed AD to require actions to 
address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by March 1, 2013.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2012-0155, dated August 20, 2012 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    On several Grob G 115 aeroplanes, elevator trim tab arms Part 
Number (P/N) 115E-3758 have been found cracked, from a rear mounting 
hole (either L/H or R/H) to the rear edge of the trim tab arm.
    This condition, if not detected and corrected, could lead to 
further crack propagation, possibly resulting in failure of the part 
and consequent loss of control of the aeroplane.
    For the reasons described above, this AD requires repetitive 
inspections of the elevator trim tab arm to detect cracks and, if 
detected, replacement of the part with a serviceable part.
    This AD also provides an optional terminating action for the 
repetitive inspections.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Grob Aircraft has issued Service Bulletin No. MSB1078-186/3, dated 
August 3, 2012. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD will affect 0 products of U.S. 
registry. We also estimate that it would take about 3 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $372 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $627 per product.

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 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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:

Grob-Werke: Docket No. FAA-2012-0013; Directorate Identifier 2012-
CE-046-AD.

(a) Comments Due Date

    We must receive comments by March 1, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to GROB-WERKE G115EG airplanes, all serial 
numbers, certificated in any category.

(d) Subject

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

(e) Reason

    This AD was prompted by the discovery of cracks in the elevator 
trim tab arms on several Grob G 115 airplanes, which could result in 
failure of the part and consequent loss of control. We are issuing 
this proposed AD to detect cracks and prevent the part from failing.

 (f) Actions and Compliance

    Unless already done, do the following actions following Grob 
Aircraft Service Bulletin No. MSB1078-186/3, dated August 3, 2012.
    (1) Within the next 50 hours time-in-service (TIS) after the 
effective date of this AD and repetitively thereafter at intervals 
not to exceed 200 hours TIS, inspect elevator trim tab arms, part 
number (P/N) 115E-3758, using a nondestructive testing (NDT) method 
such as a dye-penetrant or eddy-current.

    Note for paragraph (f)(1) of this AD:  There must be a more 
significant nondestructive testing (NDT) method of inspection beyond 
a visual inspection to accomplish the inspection requirements in 
paragraph (f)(1) of this AD.

    (2) If during any inspection required in paragraph (f)(1) of 
this AD a crack is found, before further flight, replace the 
affected elevator trim tab arm with an airworthy part.

[[Page 2912]]

    (3) Replacement at any time of an elevator trim tab arm with an 
airworthy part that has a P/N other than P/N 115E-3758, will 
terminate the repetitive requirement in paragraph (f)(1) of this AD.

(g) Credit for Actions Accomplished in Accordance With Previous Service 
Information

    This AD provides credit for the actions required in this AD if 
already done before the effective date of this AD following Grob 
Aircraft Service Bulletin No. MSB1078-186/2, dated March 28, 2012; 
Grob Aircraft Service Bulletin No. MSB1078-186/1, dated March 8, 
2012; or Grob Aircraft Service Bulletin No. MSB1078-186, dated 
February 15, 2012.
