Download as PDF Federal Register / Vol. 77, No. 180 / Monday, September 17, 2012 / Proposed Rules Conclusion ACTION: This action affects only certain novel or unusual design features on one model of airplanes. It is not a rule of general applicability. SUMMARY: List of Subjects in 14 CFR Part 25 Aircraft, Aviation safety, Reporting and recordkeeping requirements. The authority citation for these special conditions is as follows: Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704. The Proposed Special Conditions Accordingly, the Federal Aviation Administration (FAA) proposes the following special conditions as part of the type certification basis for Model EMB–550 airplanes. 1. Electronic Flight Control System: Control Surface Awareness and Mode Annunciation. In addition to the requirements of §§ 25.143, 25.671, and 25.672, the following requirements apply: a. The system design must ensure that the flightcrew is made suitably aware whenever the primary control means nears the limit of control authority. Note: The term ‘‘suitably aware’’ indicates annunciations provided to the flightcrew are appropriately balanced between nuisance and that necessary for crew awareness. b. If the design of the flight control system has multiple modes of operation, a means must be provided to indicate to the crew any mode that significantly changes or degrades the normal handling or operational characteristics of the airplane.

AGENCY: 17:54 Sep 14, 2012 We propose to supersede an existing airworthiness directive (AD) that applies to all Thielert Aircraft Engines (TAE) GmbH Models TAE 125– 01, TAE 125–02–99, and TAE 125–02– 114 Reciprocating Engines. The existing AD currently requires installation of full-authority digital electronic control (FADEC) software version 2.91. Since we issued that AD, we have received reports of possible power loss on airplanes equipped with TAE 125 engines. This proposed AD would require removing all software mapping versions prior to 292, 301, or 302, applicable to the TAE engine model. We are proposing this AD to prevent engine power loss or in-flight shutdown, resulting in reduced control of or damage to the airplane.

Discussion On March 22, 2011 we issued AD 2011–07–09, amendment 39–16646 (76 FR 17757, March 31, 2011), for Thielert Aircraft Engines GmbH models TAE 125–01, TAE 125–02–99, and TAE 125– 02–114 reciprocating engines installed in, but not limited to, Cessna 172 and (Reims-built) F172 series (European Aviation Safety Agency (EASA) STC No. EASA.A.S.01527); Piper PA–28 series (EASA STC No. EASA.A.S. 01632); APEX (Robin) DR 400 series (EASA STC No. A.S.01380); and Diamond Aircraft Industries Models DA 40, DA 42, and DA 42M NG airplanes. That AD requires installation of FADEC software version 2.91. That AD resulted from service experience that showed the FADEC channel B manifold air pressure sensor hose permeability was not always recognized as a fault by the FADEC. We issued that AD to prevent engine power loss or in-flight shutdown, resulting in reduced control of or damage to the airplane. Actions Since Existing AD Was Issued Since we issued AD 2011–07–09, we have received reports of possible power loss on airplanes equipped with TAE 125 engines. The preliminary investigation results have shown that an E:\FR\FM\17SEP1.SGM 17SEP1 57042 Federal Register / Vol. 77, No. 180 / Monday, September 17, 2012 / Proposed Rules undetected engine overspeed, due to a slipping clutch, may have contributed to these occurrences, in combination with other circumstances. Relevant Service Information We reviewed TAE Service Bulletin TM TAE 000–0007, Revision 19, dated August 31, 2012. The service information describes procedures for updating the affected FADEC software. 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 none of the requirements of AD 2011–07–09. This proposed AD would require removing all software mapping versions prior to 292, 301, or 302, applicable to the TAE engine model. Costs of Compliance We estimate that this proposed AD would affect about 112 engines installed on airplanes of U.S. registry. We also estimate that it would take about 0.5 work-hours per product to comply with this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD to U.S. operators to be $4,760. sroberts on DSK5SPTVN1PROD with PROPOSALS Authority for this Rulemaking Regulatory Findings We have determined that this proposed AD would not have federalism implications under Executive Order 17:54 Sep 14, 2012 Jkt 226001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, 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. VerDate Mar<15>2010 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.

FOR FURTHER INFORMATION CONTACT: Matthew Wilshire, (202) 326–2976, Attorney, Division of Enforcement, Bureau of Consumer Protection, Federal Trade Commission, 600 Pennsylvania Avenue NW., Washington, DC 20580. SUPPLEMENTARY INFORMATION: I. Introduction On March 14, 2011, the Federal Trade Commission (‘‘FTC’’ or ‘‘Commission’’) invited comment on its Rules and Regulations (‘‘Fur Rules’’ or ‘‘Rules’’) under the Fur Products Labeling Act (‘‘Fur Act’’ or ‘‘Act’’), including its Fur Products Name Guide (‘‘Name Guide’’).1 After considering the comments and holding a public hearing, the Commission proposes updating the Name Guide, providing greater labeling flexibility, incorporating provisions of the recently enacted Truth in Fur Labeling Act (‘‘TFLA’’), and, on its own initiative, deleting unnecessary requirements. The Commission declines to propose other amendments suggested by commenters. Although some supported changing the Name Guide’s required name for nyctereutes procyonoides, the Commission proposes retaining ‘‘Asiatic Raccoon’’ as the only name for that species. As discussed below, the record shows that ‘‘Asiatic Raccoon’’ is the best name to identify the animal for consumers. Furthermore, alternative names suggested by commenters either risk misleading consumers or cannot be used to identify the animal. This supplementary information section first provides background on the Fur Act and Rules, the Name Guide, TFLA, and this rulemaking. Next, it summarizes the comments. Finally, it analyzes those comments and discusses the proposed amendments. II. Background A. The Fur Act and Rules The Fur Act prohibits misbranding and false advertising of fur products, and requires labeling of most fur products.2 Pursuant to this Act, the Commission promulgated the Fur Rules. These Rules set forth disclosure requirements that assist consumers in making informed purchasing decisions.3 Specifically, the Fur Act and Rules 1 76 FR 13550 (Mar. 14, 2011). The Name Guide lists the English animal names that must appear on fur-product labels. 2 15 U.S.C. 69 et seq. 3 16 CFR part 301. PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 57043 require fur manufacturers, dealers, and retailers to label products made entirely or partly of fur. These labels must disclose: (1) The animal’s name as provided in the Name Guide; (2) the presence of any used, bleached, dyed, or otherwise artificially colored fur; (3) that the garment is composed of, among other things, paws, tails, bellies, sides, flanks, or waste fur, if that is the case; (4) the name or Registered Identification Number of the manufacturer or other party responsible for the garment; and (5) the product’s country of origin.4 In addition, manufacturers must include an item number or mark on the label for identification purposes.5 The Rules also include detailed labeling specifications. For example, the Rules specify an exact label size of 1.75 inches by 2.75 inches,6 require disclosures on the label in a particular order,7 and prohibit non-FTC information on the front of the label.8 Finally, the Fur Act requires the Rules to provide for separate and continuing guaranties.9 These documents allow an entity to provide a guarantee to another entity that the fur products it manufactures or transfers are not mislabeled or falsely advertised or invoiced. Separate guaranties specifically designate particular fur products.10 Continuing guaranties, which guarantors file with the Commission, apply to ‘‘any fur product or fur handled by a guarantor.’’ 11 The Act provides that a guaranty recipient will not generally be liable for violations related to the guaranteed goods.12 B. The Name Guide The Fur Act requires the Commission to maintain ‘‘a register setting forth the names of hair, fleece, and fur-bearing animals.’’ 13 The Act further requires that these names ‘‘be the true English names for the animals in question, or in the absence of a true English name for an animal, the name by which such animal can be properly identified in the United States.’’ 14 For example, the 4 15 U.S.C. 69b(2); 16 CFR 301.2(a). CFR 301.40. 6 16 CFR 301.27. 7 16 CFR 301.30. 8 16 CFR 301.29(a). By contrast, the Commission’s Rules and Regulations (‘‘Textile Rules’’) under the Textile Fiber Products Identification Act (‘‘Textile Act’’), which apply to clothing generally, do not have such restrictions. 9 15 U.S.C. 69h; 16 CFR 301.46; 301.47; 301.48; and 301.48a. 10 15 U.S.C. 69h(a)(1). 11 15 U.S.C. 69h(a)(2). 12 15 U.S.C. 69h(a). 13 15 U.S.C. 69e(a). 14 Id. 5 16 E:\FR\FM\17SEP1.SGM 17SEP1

Airworthiness Directives; Thielert Aircraft Engines GmbH Models
TAE 125-01, TAE 125-02-99, and TAE 125-02-114 Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to all Thielert Aircraft Engines (TAE) GmbH Models
TAE 125-01, TAE 125-02-99, and TAE 125-02-114 Reciprocating Engines.
The existing AD currently requires installation of full-authority
digital electronic control (FADEC) software version 2.91. Since we
issued that AD, we have received reports of possible power loss on
airplanes equipped with TAE 125 engines. This proposed AD would require
removing all software mapping versions prior to 292, 301, or 302,
applicable to the TAE engine model. We are proposing this AD to prevent
engine power loss or in-flight shutdown, resulting in reduced control
of or damage to the airplane.

DATES: We must receive comments on this proposed AD by November 16,
2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

On March 22, 2011 we issued AD 2011-07-09, amendment 39-16646 (76
FR 17757, March 31, 2011), for Thielert Aircraft Engines GmbH models
TAE 125-01, TAE 125-02-99, and TAE 125-02-114 reciprocating engines
installed in, but not limited to, Cessna 172 and (Reims-built) F172
series (European Aviation Safety Agency (EASA) STC No. EASA.A.S.01527);
Piper PA-28 series (EASA STC No. EASA.A.S. 01632); APEX (Robin) DR 400
series (EASA STC No. A.S.01380); and Diamond Aircraft Industries Models
DA 40, DA 42, and DA 42M NG airplanes. That AD requires installation of
FADEC software version 2.91. That AD resulted from service experience
that showed the FADEC channel B manifold air pressure sensor hose
permeability was not always recognized as a fault by the FADEC. We
issued that AD to prevent engine power loss or in-flight shutdown,
resulting in reduced control of or damage to the airplane.

Actions Since Existing AD Was Issued

Since we issued AD 2011-07-09, we have received reports of possible
power loss on airplanes equipped with TAE 125 engines. The preliminary
investigation results have shown that an

[[Page 57042]]

undetected engine overspeed, due to a slipping clutch, may have
contributed to these occurrences, in combination with other
circumstances.

Relevant Service Information

We reviewed TAE Service Bulletin TM TAE 000-0007, Revision 19,
dated August 31, 2012. The service information describes procedures for
updating the affected FADEC software.

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 none of the requirements of AD 2011-
07-09. This proposed AD would require removing all software mapping
versions prior to 292, 301, or 302, applicable to the TAE engine model.

Costs of Compliance

We estimate that this proposed AD would affect about 112 engines
installed on airplanes of U.S. registry. We also estimate that it would
take about 0.5 work-hours per product to comply with this proposed AD.
The average labor rate is $85 per work-hour. Based on these figures, we
estimate the cost of the proposed AD to U.S. operators to be $4,760.

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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

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

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]

2. The FAA amends Sec. 39.13 by removing airworthiness directive
(AD) 2011-07-09, Amendment 39-16646 (76 FR 17757, March 31, 2011), and
adding the following new AD:

Thielert Aircraft Engines GmbH: Docket No. FAA-2010-0820;
Directorate Identifier 2010-NE-31-AD.

(a) Comments Due Date

The FAA must receive comments on this AD action by November 16,
2012.

(b) Affected ADs

This AD supersedes AD 2011-07-09, Amendment 39-16646.

This AD applies to Thielert Aircraft Engines GmbH models TAE
125-01, TAE 125-02-99, and TAE 125-02-114 reciprocating engines
installed in, but not limited to, Cessna 172 and (Reims-built) F172
series (European Aviation Safety Agency (EASA) STC No.
EASA.A.S.01527); Piper PA-28 series (EASA STC No. EASA.A.S. 01632);
APEX (Robin) DR 400 series (EASA STC No. A.S.01380); and Diamond
Aircraft Industries Models DA 40, DA 42, and DA 42M NG airplanes.

(d) Unsafe Condition

This AD was prompted by reports of possible power loss on
airplanes equipped with TAE 125 engines. We are issuing this AD to
prevent engine power loss or in-flight shutdown, resulting in
reduced control of or damage to the airplane.

(e) Compliance

Unless already done, do the following. Within 55 flight hours or
within 3 months of the effective date of the AD, or during the next
scheduled maintenance, whichever occurs first, remove all full-
authority digital electronic control (FADEC) software prior to
versions 292, 301, and 302. Tables 1, 2, and 3 to paragraph (e)
provide the software mapping and respective part numbers for
software versions 292, 301, and 302, installed on the TAE 125-01,
TAE 125-02-99, and TAE-125-02-114 engines, respectively.
