VerDate Mar<15>2010 17:15 Sep 10, 2014 Jkt 232001 Discussion We issued Special Airworthiness Information Bulletin (SAIB) NE–08–32 on July 3, 2008. The SAIB recommended actions to correct the condition of a propeller governor shaft set screw coming loose. This proposed AD was prompted by additional events of propeller governor shaft set screws coming loose due to improper installation, which could result in the shaft penetrating the plug at the front of the crankcase and causing a loss of engine oil and a loss of engine power. In some reported events, engine oil was deposited on the windshield, restricting pilot visibility. The loose set screw could also enter the rotating system and cause damage to the camshaft and valve lifters. Safety is further diminished if failure occurs during aerobatic maneuvers, especially at low altitudes, due to reduction in pilot reaction time. These conditions, if not corrected, could result in damage to the engine, and damage to the airplane. This proposed AD would require application of Loctite 290, or equivalent, to the threads of the propeller governor shaft set screw at each installation of the set screw in addition to the peening of crankcase hole threads. We are proposing this AD to prevent the propeller governor shaft set screw from coming loose, causing damage to the engine, and damage to the airplane. Relevant Service Information We reviewed Lycoming Engines Service Instruction (SI) No. 1343B, dated June 15, 2007. The SI describes procedures for securing the propeller governor shaft set screw. 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 these same type designs. Proposed AD Requirements This proposed AD would require application of Loctite 290, or equivalent, to the threads of the propeller governor shaft set screw at each installation of the set screw in addition to the peening of crankcase hole threads. Differences Between This Proposed AD and the Service Information Lycoming Engines SI No. 1343B, dated June 15, 2007, specifies the use of Loctite 290, in addition to peening of the crankcase hole threads, to secure the set screw in place. This AD allows the use of Loctite 290, or equivalent threadlocking, anaerobic, single-component PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 54219 sealing compound that meets military specification Mil-S–46163A, Type III, Grade R. The SI also requires these actions at next overhaul, whereas this AD requires these actions at any installation of the propeller governor shaft set screw. Costs of Compliance We estimate that this proposed AD would affect about 2,330 engines installed on airplanes of U.S. registry. We also estimate that it will take about 0.1 hours per engine to comply with this AD. The average labor rate is $85 per hour. Prorated parts life will cost about $1 per engine. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $22,135. 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 to the extent that it justifies making a regulatory distinction, and (4) Will not have a significant economic impact, positive or negative, E:\FR\FM\11SEP1.SGM 11SEP1 54220 Federal Register / Vol. 79, No. 176 / Thursday, September 11, 2014 / Proposed Rules on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

screws coming loose due to improper installation, which could result in 
engine oil loss, damage to the engine, and damage to the airplane. This 
proposed AD would require application of Loctite 290, or equivalent, to 
the threads of the propeller governor shaft set screw at each

Discussion

    We issued Special Airworthiness Information Bulletin (SAIB) NE-08-
32 on July 3, 2008. The SAIB recommended actions to correct the 
condition of a propeller governor shaft set screw coming loose. This 
proposed AD was prompted by additional events of propeller governor 
shaft set screws coming loose due to improper installation, which could 
result in the shaft penetrating the plug at the front of the crankcase 
and causing a loss of engine oil and a loss of engine power. In some 
reported events, engine oil was deposited on the windshield, 
restricting pilot visibility. The loose set screw could also enter the 
rotating system and cause damage to the camshaft and valve lifters. 
Safety is further diminished if failure occurs during aerobatic 
maneuvers, especially at low altitudes, due to reduction in pilot 
reaction time. These conditions, if not corrected, could result in 
damage to the engine, and damage to the airplane. This proposed AD 
would require application of Loctite 290, or equivalent, to the threads 
of the propeller governor shaft set screw at each installation of the 
set screw in addition to the peening of crankcase hole threads. We are 
proposing this AD to prevent the propeller governor shaft set screw 
from coming loose, causing damage to the engine, and damage to the 
airplane.

Relevant Service Information

    We reviewed Lycoming Engines Service Instruction (SI) No. 1343B, 
dated June 15, 2007. The SI describes procedures for securing the 
propeller governor shaft set screw.

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 these same type 
designs.

Proposed AD Requirements

    This proposed AD would require application of Loctite 290, or 
equivalent, to the threads of the propeller governor shaft set screw at 
each installation of the set screw in addition to the peening of 
crankcase hole threads.

Differences Between This Proposed AD and the Service Information

    Lycoming Engines SI No. 1343B, dated June 15, 2007, specifies the 
use of Loctite 290, in addition to peening of the crankcase hole 
threads, to secure the set screw in place. This AD allows the use of 
Loctite 290, or equivalent thread-locking, anaerobic, single-component 
sealing compound that meets military specification Mil-S-46163A, Type 
III, Grade R. The SI also requires these actions at next overhaul, 
whereas this AD requires these actions at any installation of the 
propeller governor shaft set screw.

Costs of Compliance

    We estimate that this proposed AD would affect about 2,330 engines 
installed on airplanes of U.S. registry. We also estimate that it will 
take about 0.1 hours per engine to comply with this AD. The average 
labor rate is $85 per hour. Prorated parts life will cost about $1 per 
engine. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $22,135.

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 to the extent 
that it justifies making a regulatory distinction, and
    (4) Will not have a significant economic impact, positive or 
negative,

    None.

(c) Applicability

    This AD applies to all Lycoming Engines wide deck aerobatic 
reciprocating engines that have either an ``A'' or an ``E'' at the 
end of the serial number (e.g., L-12345-51A, or L-12345-51E) and are 
equipped with a front-mounted propeller governor. Affected 
reciprocating engine models include, but are not limited to Lycoming 
Engines AEIO-320-D1B; AEIO-360-A1E, -A1E6, -B1H, -H1B; AEIO-540-

(d) Unsafe Condition

    This AD was prompted by events of propeller governor shaft set 
screws coming loose due to improper installation, which could result 
in engine oil loss, damage to the engine, and damage to the

shaft set screw from coming loose, causing damage to the engine, and 
damage to the airplane.

unless already done.
    After the effective date of this AD, at each installation of the 
propeller governor shaft set screw, secure the set screw in place in 
accordance with the instructions of Lycoming Engines Service
