Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD No. 2013–0044–E, dated February 27, E:\FR\FM\24JYR1.SGM 24JYR1 Federal Register / Vol. 78, No. 142 / Wednesday, July 24, 2013 / Rules and Regulations 2013, to correct an unsafe condition for Eurocopter Model AS350B, AS350BA, AS350BB, AS350B1, AS350B2, AS350B3, and AS350D helicopters. EASA advises that six events were reported of hydraulic pump drive belt failure caused by seizure of the pulley bearing, and that a preliminary investigation concluded the installation of a new hydraulic pump drive (installed in accordance with Eurocopter modification 079566) may have caused excessive degradation. EASA further states that this condition, for helicopters with a single hydraulic system, can lead to loss of hydraulic servo assistance and an increase in pilot work load that requires landing as soon as possible. For these reasons, the EASA AD requires repetitive inspections of the hydraulic pump drive belt and pulley bearing and if required, replacing the hydraulic pump drive assembly. FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. ehiers on DSK2VPTVN1PROD with RULES Related Service Information Eurocopter issued AS350 Emergency Alert Service Bulletin No. 05.00.72, Revision 1, dated June 11, 2013 (EASB 05.00.72), for Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, ASAS350D, and for non-FAA typecertificated Models AS350L1 and AS350BB helicopters. EASB 05.00.72 describes procedures for inspecting the pulley bearing for leaking grease, condition of the lip seals, rust on the lip seals, evidence of overheating revealed by brown discoloring of the bearing, and for the condition of the sealing flanges. EASB 05.00.72 also describes procedures for rotating the bearing manually to determine if there are any friction points, brinelling, or noises from the bearing. EASB 05.00.72 requires these inspections within 10 hours time-in-service (TIS) for installed bearings with 165 or more hours TIS since installation. For bearings with less than 165 hours TIS since installation, EASB 05.00.72 requires inspecting the bearing upon reaching 165 hours TIS. VerDate Mar<15>2010 15:33 Jul 23, 2013 Jkt 229001 AD Requirements This AD requires, for hydraulic pump drives with 165 or more hours TIS since installation, within 10 hours TIS and thereafter at intervals not exceeding 25 hours TIS, decoupling the pulley and inspecting the pulley bearing for leaking grease, a crack or tear in the lip seals, a run of rust on the lip seals, indication of overheating shown by brown coloring on the inner ring of the bearing, any distortion, impact, wear, a tear, a crack, or loss of grease on the sealing flanges, or for a friction point, brinelling, or noise from the bearing. If any of these conditions exist, this AD requires replacing the hydraulic pump drive assembly before further flight. If the hydraulic pump drive assembly is replaced, the repetitive inspection requirements of this AD still apply. Interim Action We consider this AD to be an interim action. Eurocopter is still investigating the cause of this condition. If a final action is later identified, we might consider additional rulemaking. Costs of Compliance We estimate that this AD will affect 36 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85 per hour, inspecting the bearing pulley would require about 1.5 work-hours, for a cost per helicopter of $128, and a total cost to U.S. operators of $4,608, per inspection cycle. If required, replacing the hydraulic pump drive assembly would require about 1.5 work-hours, and required parts would cost about $8,543, for a total cost per helicopter of $8,671. According to Eurocopter’s service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Eurocopter. Accordingly, we have included all costs in our cost estimate. FAA’s Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because the required corrective actions must be accomplished within 10 hours TIS, a very short time period based on the average flight-hour PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 44423 utilization rate of these helicopters in the helicopter emergency medical service and air tour industries. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in less than 30 days. 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 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, 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 to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Emergency AD No. 2013-0044-E, dated February 27,

[[Page 44423]]

2013, to correct an unsafe condition for Eurocopter Model AS350B, 
AS350BA, AS350BB, AS350B1, AS350B2, AS350B3, and AS350D helicopters. 
EASA advises that six events were reported of hydraulic pump drive belt 
failure caused by seizure of the pulley bearing, and that a preliminary 
investigation concluded the installation of a new hydraulic pump drive 
(installed in accordance with Eurocopter modification 079566) may have 
caused excessive degradation. EASA further states that this condition, 
for helicopters with a single hydraulic system, can lead to loss of 
hydraulic servo assistance and an increase in pilot work load that 
requires landing as soon as possible. For these reasons, the EASA AD 
requires repetitive inspections of the hydraulic pump drive belt and 
pulley bearing and if required, replacing the hydraulic pump drive 
assembly.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs.

Related Service Information

    Eurocopter issued AS350 Emergency Alert Service Bulletin No. 
05.00.72, Revision 1, dated June 11, 2013 (EASB 05.00.72), for Model 
AS350B, AS350BA, AS350B1, AS350B2, AS350B3, ASAS350D, and for non-FAA 
type-certificated Models AS350L1 and AS350BB helicopters. EASB 05.00.72 
describes procedures for inspecting the pulley bearing for leaking 
grease, condition of the lip seals, rust on the lip seals, evidence of 
overheating revealed by brown discoloring of the bearing, and for the 
condition of the sealing flanges. EASB 05.00.72 also describes 
procedures for rotating the bearing manually to determine if there are 
any friction points, brinelling, or noises from the bearing. EASB 
05.00.72 requires these inspections within 10 hours time-in-service 
(TIS) for installed bearings with 165 or more hours TIS since 
installation. For bearings with less than 165 hours TIS since 
installation, EASB 05.00.72 requires inspecting the bearing upon 
reaching 165 hours TIS.

AD Requirements

    This AD requires, for hydraulic pump drives with 165 or more hours 
TIS since installation, within 10 hours TIS and thereafter at intervals 
not exceeding 25 hours TIS, decoupling the pulley and inspecting the 
pulley bearing for leaking grease, a crack or tear in the lip seals, a 
run of rust on the lip seals, indication of overheating shown by brown 
coloring on the inner ring of the bearing, any distortion, impact, 
wear, a tear, a crack, or loss of grease on the sealing flanges, or for 
a friction point, brinelling, or noise from the bearing. If any of 
these conditions exist, this AD requires replacing the hydraulic pump 
drive assembly before further flight. If the hydraulic pump drive 
assembly is replaced, the repetitive inspection requirements of this AD 
still apply.

Interim Action

    We consider this AD to be an interim action. Eurocopter is still 
investigating the cause of this condition. If a final action is later 
identified, we might consider additional rulemaking.

Costs of Compliance

    We estimate that this AD will affect 36 helicopters of U.S. 
Registry. We estimate that operators may incur the following costs in 
order to comply with this AD.
    At an average labor rate of $85 per hour, inspecting the bearing 
pulley would require about 1.5 work-hours, for a cost per helicopter of 
$128, and a total cost to U.S. operators of $4,608, per inspection 
cycle.
    If required, replacing the hydraulic pump drive assembly would 
require about 1.5 work-hours, and required parts would cost about 
$8,543, for a total cost per helicopter of $8,671.
    According to Eurocopter's service information, some of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected individuals. We do not control warranty coverage by 
Eurocopter. Accordingly, we have included all costs in our cost 
estimate.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD requirements would delay implementing the safety actions 
needed to correct this known unsafe condition. Therefore, we find that 
the risk to the flying public justifies waiving notice and comment 
prior to the adoption of this rule because the required corrective 
actions must be accomplished within 10 hours TIS, a very short time 
period based on the average flight-hour utilization rate of these 
helicopters in the helicopter emergency medical service and air tour 
industries.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

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 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, 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 to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.

25 hours TIS:
    (1) Uncouple the pulley from the hydraulic pump.
    (2) Using a mirror and a light, inspect the hydraulic pump drive 
pulley bearing (pulley bearing) for leaking grease from each lip 
seal of the four greasing orifices (lip seal) due to wear, a crack 
or tear in a lip seal, a run of rust on a lip seal, indication of 
overheating shown by brown coloring on the inner ring of the 
bearing, and for any distortion, impact, wear, a tear, a crack, or 
loss of grease on each sealing flange.
    (3) Manually rotate the pulley bearing through several full 
turns and inspect for a friction point, brinelling, or a noise from 
the bearing.
    (4) If there is any leaking grease from a lip seal, a crack or 
tear in a lip seal, a run of rust on a lip seal, indication of 
overheating shown by brown coloring on the inner ring of the
