SUPPLEMENTARY INFORMATION: Discussion pmangrum on DSK3VPTVN1PROD with RULES The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, issued EASA AD 2011– 0087–E, dated May 12, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: In-flight engine shutdown incidents have been reported on aeroplanes equipped with TAE 125 engines. Preliminary investigations showed that it was mainly the result of the sensitivity of friction disk Part Number (P/N) 05–7211– K010201 against possible misalignment of gearbox and core engine during assembly. This condition, if not corrected, could result in further cases of engine in-flight VerDate Mar<15>2010 15:16 Jan 26, 2012 Jkt 226001 shutdown and consequent loss of control of the aeroplane. To address this unsafe condition, Thielert Aircraft Engines GmbH has developed a new friction disk. We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on October 18, 2011 (76 FR 64289). That NPRM was proposed to require on all TAE 125–02–99 and TAE 125–02–114 reciprocating engines, replacing the friction disk, P/N 05– 7211–K010201. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (76 FR 64289, October 18, 2011). Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance Based on the service information, we estimate that this AD will affect about 206 TAE 125–02–99 and TAE 125–02– 114 reciprocating engines installed on airplanes of U.S. registry. We also estimate that it will take about 3 workhours per engine to comply with this AD. The average labor rate is $85 per work-hour. Required parts will cost about $1,500 per engine. Based on these figures, we estimate the cost of the AD on U.S. operators to be $361,530. Our cost estimate is exclusive of possible warranty coverage. 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. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 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.

SUPPLEMENTARY INFORMATION: SUMMARY: Background On July 12, 2005, the FAA published SFAR 106, ‘‘Use of Certain Portable PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 4219 Oxygen Concentrator Devices Onboard Aircraft’’ (70 FR 40156). SFAR 106 permits passengers to carry on and use certain small portable oxygen concentrators (POCs) on board aircraft if the operator ensures compliance with conditions specified in the SFAR. Some of the devices determined acceptable for use in SFAR 106 are Delphi Medical Systems’ RS–00400 (added to the SFAR in 74 FR 2351) and International Biophysics Corporation’s LifeChoice (added to the SFAR in 75 FR 739). As a result of business changes that took place after SFAR 106 was published, the LifeChoice POC is now manufactured by Inova Labs, Inc. and not by the International Biophysics Corporation. Similarly, the RS–00400 POC is now manufactured by Oxus, Inc. and not by Delphi Medical Systems. The two companies currently manufacturing these POCs have petitioned the FAA to amend SFAR 106, Section 2 and section 3(a), of Title 14, Code of Federal Regulations (14 CFR). This amendment would update section 2 and section 3(a) of SFAR 106 with the names of the current manufacturers of the LifeChoice and RS–00400 POCs. Technical Amendment LifeChoice and RS–00400 are still the same products that were originally approved in SFAR 106—only the names of their manufacturers have changed. As such, this technical amendment makes two revisions to the final rule. First, the language in SFAR 106 section 2 and section 3(a) is revised to refer to LifeChoice as being manufactured by Inova Labs. Second, the reference to the RS–00400 POC is revised to refer to this device as being manufactured by Oxus, Inc. Because the changes in this technical amendment result in no substantive change, we find good cause exists under 5 U.S.C. 553(d)(3) to make the amendment effective in less than 30 days.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, issued EASA AD 
2011-0087-E, dated May 12, 2011 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    In-flight engine shutdown incidents have been reported on 
aeroplanes equipped with TAE 125 engines.
    Preliminary investigations showed that it was mainly the result 
of the sensitivity of friction disk Part Number (P/N) 05-7211-
K010201 against possible misalignment of gearbox and core engine 
during assembly.
    This condition, if not corrected, could result in further cases 
of engine in-flight shutdown and consequent loss of control of the 
aeroplane.
    To address this unsafe condition, Thielert Aircraft Engines GmbH 
has developed a new friction disk.

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM published in the Federal Register on October 18, 2011 (76 FR 
64289). That NPRM was proposed to require on all TAE 125-02-99 and TAE 
125-02-114 reciprocating engines, replacing the friction disk, P/N 05-
7211-K010201.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (76 FR 64289, October 18, 
2011).

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 206 TAE 125-02-99 and TAE 125-02-114 reciprocating engines 
installed on airplanes of U.S. registry. We also estimate that it will 
take about 3 work-hours per engine to comply with this AD. The average 
labor rate is $85 per work-hour. Required parts will cost about $1,500 
per engine. Based on these figures, we estimate the cost of the AD on 
U.S. operators to be $361,530. Our cost estimate is exclusive of 
possible warranty coverage.

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

    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.

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 airworthiness 
directive (AD):

2012-02-05 Thielert Aircraft Engines GmbH: Amendment 39-16928; 
Docket No. FAA-2011-0956; Directorate Identifier 2011-NE-23-AD.

(a) Effective Date

    This AD is effective March 2, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Thielert Aircraft Engines GmbH TAE 125-
02-99 and TAE-125-02-114 reciprocating engines with friction disk, 
part number (P/N) 05-7211-K010201, installed.

(d) Reason

    This AD was prompted by in-flight engine shutdown incidents 
reported on airplanes equipped with TAE 125 engines. Preliminary 
investigations showed that it was mainly the result of the 
sensitivity of friction disk P/N

[[Page 4219]]

05-7211-K010201 against possible misalignment of gearbox and core 
engine during assembly. We are issuing this AD to prevent in-flight 
engine shutdown, which could result in loss of control of the 
airplane.

(e) Actions and Compliance

    Unless already done, do the following actions.

(1) TAE 125-02-99 Engines, P/Ns 05-7200-K000201; 05-7200-K000701; 05-
7200-K000101; 05-7200-K000901; 05-7200-K001101; and 05-7200-K001301; 
and TAE 125-02-114 Engines, P/Ns 05-7200-K000501; 05-7200-K000801; and 
05-7200-K001401
