(R–RM) Series Reciprocating Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for certain TCM and R–RM series reciprocating engines. That AD currently requires replacement of certain magnetos if they fall within the SUMMARY: PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 specified serial number (S/N) range, inspection of the removed magneto to verify that the stop pin is still in place, and, if the stop pin is not in place, inspection of the engine gear train, crankcase, and accessory case. This new AD corrects the range of S/Ns affected, requires the same replacement and inspections, and adds R–RM C–125, C– 145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines to the applicability. This AD was prompted by our awareness of an error in the previous AD applicability in the range of magneto S/Ns affected and of the need to include certain engines made by R–RM, under license of TCM. We are issuing this AD to prevent engine failure and loss of control of the airplane due to migration of the magneto impulse coupling stop pin out of the magneto frame and into the gear train of the engine. DATES: This AD is effective January 24, 2012.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR E:\FR\FM\20DER1.SGM 20DER1 Federal Register / Vol. 76, No. 244 / Tuesday, December 20, 2011 / Rules and Regulations part 39 to supersede AD 2002–13–04, amendment 39–12792 (67 FR 43230, June 27, 2002). That AD applies to the specified products. The NPRM published in the Federal Register on June 28, 2011 (76 FR 37682). That NPRM proposed to continue to require replacement of certain magnetos if they fall within the specified S/N range, inspection of the removed magneto to verify that the stop pin is still in place, and, if the stop pin is not in place, inspection of the engine gear train, crankcase, and accessory case. That NPRM also proposed to correct the range of S/Ns affected and add R–RM C– 125, C–145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines to the applicability. We are issuing this AD to prevent engine failure and loss of control of the airplane due to migration of the magneto impulse coupling stop pin out of the magneto frame and into the gear train of the engine. Authority for This Rulemaking § 39.13 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. ■ Comments Regulatory Findings We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal and the FAA’s response to this comment. Question on Who the AD Is Written Against A commenter, not further identified, asked why the AD was issued against TCM and not ‘‘Slick.’’ We do not agree. We write ADs against either a product or an appliance. In the case of this AD, magnetos are part of the engine type certificate and, therefore, considered part of the product (the engine). We did not change the AD as a result of this comment. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance pmangrum on DSK3VPTVN1PROD with RULES 78809 We estimate that this AD affects 100 R–RM C–125, C–145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines installed on airplanes of U.S. registry. We also estimate that it will take about 2 workhours per engine to perform the inspections, and that the average labor rate is $85 per work-hour. Based on these figures, we estimate the total cost of this AD to U.S. operators to be $17,000. Our cost estimate is exclusive of possible warranty coverage. VerDate Mar<15>2010 15:31 Dec 19, 2011 Jkt 226001 We have 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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by 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 1.

Box 25082 Oklahoma City, OK 73125) telephone: (405) 954–4164. SUPPLEMENTARY INFORMATION: This rule amends Title 14, Code of Federal Regulations, part 97 (14 CFR part 97) by amending the referenced SIAPs. The complete regulatory description of each SIAP is listed on the appropriate FAA Form 8260, as modified by the National Flight Data Center (FDC)/Permanent Notice to Airmen (P–NOTAM), and is incorporated by reference in the amendment under 5 U.S.C. 552(a), 1 CFR part 51, and § 97.20 of Title 14 of the Code of Federal Regulations. The large number of SIAPs, their complex nature, and the need for a special format make their verbatim publication in the Federal Register expensive and impractical. Further, airmen do not use the regulatory text of the SIAPs, but refer to their graphic depiction on charts printed by publishers of aeronautical materials. Thus, the advantages of incorporation by reference are realized and publication of the complete description of each SIAP contained in FAA form documents is unnecessary. This amendment provides the affected CFR sections and specifies the types of SIAP and the corresponding effective dates. This amendment also identifies the airport and its location, the procedure and the amendment number. The Rule This amendment to 14 CFR part 97 is effective upon publication of each separate SIAP as amended in the transmittal. For safety and timeliness of change considerations, this amendment incorporates only specific changes contained for each SIAP as modified by FDC/P–NOTAMs. The SIAPs, as modified by FDC P–NOTAM, and contained in this amendment are based on the criteria contained in the U.S. Standard for E:\FR\FM\20DER1.SGM 20DER1

Airworthiness Directives; Teledyne Continental Motors (TCM) and 
Rolls-Royce Motors Ltd. (R-RM) Series Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain TCM and R-RM series reciprocating engines. That AD 
currently requires replacement of certain magnetos if they fall within 
the specified serial number (S/N) range, inspection of the removed 
magneto to verify that the stop pin is still in place, and, if the stop 
pin is not in place, inspection of the engine gear train, crankcase, 
and accessory case. This new AD corrects the range of S/Ns affected, 
requires the same replacement and inspections, and adds R-RM C-125, C-
145, O-300, IO-360, TSIO-360, and LTSIO-520-AE series reciprocating 
engines to the applicability. This AD was prompted by our awareness of 
an error in the previous AD applicability in the range of magneto S/Ns 
affected and of the need to include certain engines made by R-RM, under 
license of TCM. We are issuing this AD to prevent engine failure and 
loss of control of the airplane due to migration of the magneto impulse 
coupling stop pin out of the magneto frame and into the gear train of 
the engine.

DATES: This AD is effective January 24, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR

[[Page 78809]]

part 39 to supersede AD 2002-13-04, amendment 39-12792 (67 FR 43230, 
June 27, 2002). That AD applies to the specified products. The NPRM 
published in the Federal Register on June 28, 2011 (76 FR 37682). That 
NPRM proposed to continue to require replacement of certain magnetos if 
they fall within the specified S/N range, inspection of the removed 
magneto to verify that the stop pin is still in place, and, if the stop 
pin is not in place, inspection of the engine gear train, crankcase, 
and accessory case. That NPRM also proposed to correct the range of S/
Ns affected and add R-RM C-125, C-145, O-300, IO-360, TSIO-360, and 
LTSIO-520-AE series reciprocating engines to the applicability. We are 
issuing this AD to prevent engine failure and loss of control of the 
airplane due to migration of the magneto impulse coupling stop pin out 
of the magneto frame and into the gear train of the engine.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and the FAA's response to this comment.

Question on Who the AD Is Written Against

    A commenter, not further identified, asked why the AD was issued 
against TCM and not ``Slick.''
    We do not agree. We write ADs against either a product or an 
appliance. In the case of this AD, magnetos are part of the engine type 
certificate and, therefore, considered part of the product (the 
engine). We did not change the AD as a result of this comment.

Conclusion

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

Costs of Compliance

    We estimate that this AD affects 100 R-RM C-125, C-145, O-300, IO-
360, TSIO-360, and LTSIO-520-AE series reciprocating engines installed 
on airplanes of U.S. registry. We also estimate that it will take about 
2 work-hours per engine to perform the inspections, and that the 
average labor rate is $85 per work-hour. Based on these figures, we 
estimate the total cost of this AD to U.S. operators to be $17,000. 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

    We have 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 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.

List of Subjects in 14 CFR Part 39

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 removing airworthiness directive (AD) 
2002-13-04, Amendment 39-12792 (67 FR 43230, June 27, 2002), and adding 
the following new AD:

2011-26-07 Teledyne Continental Motors (TCM) and Rolls-Royce Motors 
Ltd. (R-RM) Series Reciprocating Engines: Amendment 39-16897; Docket 
No. FAA-2011-0085; Directorate Identifier 2000-NE-19-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective January 24, 2012.

(b) Affected ADs

    This AD supersedes AD 2002-13-04, Amendment 39-12792 (67 FR 
43230, June 27, 2002).

(c) Applicability

    This AD applies to TCM and R-RM C-125, C-145, O-300, IO-360, 
TSIO-360, and LTSIO-520-AE series reciprocating engines with 
Champion Aerospace (formerly Unison Industries) Slick Magnetos, 
models 6314, 6324, and 6364, with magneto serial numbers (S/Ns) of 
99110001 through 99129999, inclusive.

(d) Unsafe Condition

    This AD was prompted by an error in the previous AD 
applicability in the range of magneto S/Ns affected, and by the need 
to include certain engines made by R-RM, under license of TCM. We 
are issuing this AD to prevent engine failure and loss of control of 
the airplane due to migration of the magneto impulse coupling stop 
pin out of the magneto frame and into the gear train of the engine.

(e) Compliance

    Comply with this AD within 10 flight hours after the effective 
date of this AD, unless already done.

(f) Replacement of Magneto

    Replace any magneto that has an S/N of 99110001 through 
99129999, inclusive, with a magneto that does not have a serial 
number in that range. If a magneto is not in this S/N range, no 
further action is required by this AD.

(g) Inspections

    Inspect each removed magneto to verify that the impulse coupling 
stop pin is present. If the pin is missing, do the following:
    (1) For C-125, C-145, O-300, IO-360, and TSIO-360 series 
engines, do the following:
    (i) Remove magnetos, alternator or generator, and starter 
adapter from the accessory case.
    (ii) Remove the accessory case from the crankcase and oil sump.
    (iii) Visually inspect the entire engine gear train for damaged 
or broken gears and gear teeth.
    (iv) Inspect visible portions of the engine crankcase and 
accessory case for damage due to the stop pin becoming lodged 
between the engine gear train and the crankcase or accessory case.

[[Page 78810]]

    (v) If the accessory case is damaged, repair or replace the 
accessory case.
    (vi) If the engine crankcase is damaged, disassemble the engine, 
and repair or replace the crankcase.
    (vii) Inspect the oil pump drive gear teeth and inner cam gear 
teeth for damage. Replace any engine drive train component that has 
been damaged.
    (viii) Replace any damaged gear, and magnaflux the mating gears 
using the applicable engine overhaul manual.
    (2) For LTSIO-520-AE series engines, do the following:
    (i) Remove the starter adapter, fuel pump, vacuum pumps, 
accessory drive pads, and both magnetos.
    (ii) Visually inspect the entire engine gear train for damaged 
or broken gears and gear teeth.
    (iii) If any damage has occurred, remove the engine from the 
airplane, disassemble the engine, and inspect it for damage. If any 
damage is found, repair as necessary.
    (iv) Replace any damaged gear, and magnaflux the mating gears 
using the applicable engine overhaul manual.
    (v) Inspect the interior portions of the engine crankcase for 
damage due to the stop pin becoming lodged between the gear train 
and the crankcase. If the crankcase is damaged, repair or replace 
the crankcase.

(h) Installation Prohibition

    After the effective date of this AD, do not install any Champion 
Aerospace (formerly Unison Industries) Slick magnetos, model 6314, 
6324, or 6364 that have an S/N of 99110001 through 99129999, 
inclusive, on any engine.

(i) Alternative Methods of Compliance

    The Manager, Atlanta Aircraft Certification Office, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19.

(j) Related Information

    (1) A cross-reference for part numbers (P/Ns) for Champion 
Aerospace (formerly Unison Industries) Slick magneto model 6314 (TCM 
P/N 653271), model 6324 (TCM P/N 653292), and model 6364 (TCM P/N 
649696) can be found in TCM Mandatory Service Bulletin MSB00-6D,
