SUMMARY: This document publishes in 

the Federal Register an amendment 

adopting Airworthiness Directive (AD) 

2010–16–51, which was sent previously 

to all known U.S. owners and operators 

of Eurocopter France (Eurocopter) 

Model SA330J helicopters by individual 

letters. This AD requires, within 10 

hours time-in-service (TIS), inspecting 

for a gap between the main gearbox 

(MGB) oil cooling fan assembly (fan) 

rotor blade and the upper section of the 

guide vane bearing housing. This 

inspection must be accomplished by 

using a feeler gauge attached to a rigid 

rod. If the feeler gauge cannot be 

inserted between the blade and the 

housing, this AD requires replacing the 

two fan rotor shaft bearings with two 

airworthy bearings. This AD is 

prompted by the separation of a fan 

rotor blade that caused puncture holes 

in the transmission deck. This 

condition, if not corrected, could lead to 

damage to the hydraulic lines and flight 

controls, and subsequent loss of control 

of the helicopter. 

DATES: Effective September 17, 2010, to 

all persons except those persons to 

whom it was made immediately 

effective by Emergency AD 2010–16–51, 

issued on July 19, 2010, which 

contained the requirements of this 

amendment. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

17, 2010.

SUPPLEMENTARY INFORMATION: On July 

19, 2010, we issued Emergency AD 

2010–16–51 for Eurocopter Model 

SA330J helicopters, which requires, 

within 10 hours TIS, inspecting for a 

gap between the MGB fan rotor blade 

and the upper section of the guide vane 

bearing housing over the entire width of 

the blade. The inspection must be 

accomplished by using a 0.2 millimeter 

(mm) (0.008 inch) feeler gauge attached 

to a rigid rod. If the feeler gauge cannot 

be inserted between the upper blade and 

the upper housing, the Emergency AD 

requires replacing the two fan rotor 

shaft bearings with two airworthy 

bearings. That action was prompted by 

a rotor burst of MGB oil fan. 

Investigation of the incident has shown 

that some fan rotor blades struck the 

upper area of the guide vane bearing 

housing of the fan and separated from 

the rotor, striking the MGB 

compartment environment, and 

punctured holes in the transmission 

deck. This interference was due to 

internal degradation of the bearings of 

the fan rotor shaft. This condition, if not 

corrected, could lead to fan rotor burst, 

damage to the hydraulic lines and flight 

controls, and subsequent loss of control 

of the helicopter. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, notified us that an unsafe 

condition may exist on these helicopter 

models. EASA advises of a case of rotor 

burst of a fan. Investigation has shown 

that some fan rotor blades interfered 

with the upper area of the guide vane 

bearing housing of the fan. The blades 

detached from the rotor, impacted the 

MGB compartment environment, and 

punctured holes in the transmission 

deck. This interference was due to 

internal degradation of the bearings of 


emcdonald on DSK2BSOYB1PROD with RULES
53858 Federal Register / Vol. 75, No. 170 / Thursday, September 2, 2010 / Rules and Regulations 

the fan rotor shaft. EASA states that this 

condition, if not corrected could lead to 

fan rotor burst and possibly result in 

damage to hydraulic pipes and flight 

controls located nearby the MGB 

cooling fan. 

Eurocopter has issued Emergency 

Alert Service Bulletin No. 05.96, dated 

July 12, 2010 (EASB), for Model SA330J 

helicopters and for non-FAA typecertificated Model SA330Ba, Ca, Ea, L, 

Jm, S1, and Sm military helicopters. The 

EASB specifies checking for a minimum 

play of 0.2 millimeters (mm) between a 

fan blade and the guide vane bearing 

housing using a locally manufactured 

tool. The EASB also states that if the 

minimum play is not complied with, 

replace the two bearings of the fan rotor 

shaft. EASA classified the EASB as 

mandatory and issued AD No. 2010– 

0147–E, dated July 14, 2010, to ensure 

the continued airworthiness of these 

helicopters. This AD differs from EASA 

Emergency AD No. 2010–0142–E in that 

we use the term ‘‘hours time-in-service’’ 

rather than ‘‘flight hours.’’ Also, for 

clarification, we specify inspecting for a 

‘‘gap’’ rather than checking for ‘‘play.’’ 

This helicopter model is 

manufactured in France and is type 

certificated for operation in the United 

States under the provisions of 14 CFR 

21.29 and the applicable bilateral 

agreement. Pursuant to the applicable 

bilateral agreement, EASA has kept us 

informed of the situation described 

above. We have examined the findings 

of EASA, reviewed all available 

information, and determined that AD 

action is necessary for helicopters of 

this type design that are certificated for 

operation in the United States. 

Since the unsafe condition described 

is likely to exist or develop on other 

Eurocopter Model SA330J helicopters of 

the same type design, we issued 

Emergency AD 2010–16–51 to prevent a 

rotor burst of the MGB fan, damage to 

the hydraulic lines and flight controls, 

and subsequent loss of control of the 

helicopter. The Emergency AD requires, 

within 10 hours TIS, using a 0.2 mm 

(0.008 inch) feeler gauge attached to a 

rigid rod, inspecting for a gap between 

a fan rotor blade and the upper section 

of the guide vane bearing housing over 

the entire width of the blade. If the 

feeler gauge can be inserted between the 

blade and the housing (a gap greater 

than or equal to 0.2 mm), no further 

action is required. If the feeler gauge 

cannot be inserted between the blade 

and the housing (a gap less than 0.2 

mm), replacing the two fan rotor shaft 

bearings with two airworthy bearings is 

required. After installing airworthy 

bearings, reinspecting the gap to ensure 

there is sufficient clearance between the 

blade and the housing is also required. 

The actions must be accomplished by 

following specified portions of the 

EASB described previously. 

The short compliance time involved 

is required because the previously 

described critical unsafe condition can 

adversely affect the structural integrity 

and controllability of the helicopter. 

Therefore, the actions previously 

described are required within a very 

short time period, and this AD must be 

issued immediately. 

Since it was found that immediate 

corrective action was required, notice 

and opportunity for prior public 

comment thereon were impracticable 

and contrary to the public interest, and 

good cause existed to make the AD 

effective immediately by individual 

letters issued on July 19, 2010 to all 

known U.S. owners and operators of 

Eurocopter Model SA330J helicopters. 

These conditions still exist, and the AD 

is hereby published in the Federal 

Register as an amendment to 14 CFR 

39.13 to make it effective to all persons. 

We estimate that this AD will affect 

12 helicopters of U.S. registry. Each 

inspection will take approximately 2 

work hours. Replacing both bearings on 

each helicopter will take approximately 

6 work hours. The average labor rate is 

$85 per work hour. Required parts will 

cost approximately $935 per helicopter 

(2 bearings per helicopter). Based on 

these figures, we estimate the total cost 

impact of the AD on U.S. operators to 

be $19,380 ($1,615 per helicopter, 

assuming 1 inspection and replacement 

of both bearings on each helicopter). 

Comments Invited 

This AD is a final rule that involves 

requirements that affect flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to submit any 

written data, views, or arguments 

regarding this AD. Send your comments 

to an address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2010–0825; 

Directorate Identifier 2010–SW–072– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

the AD. We will consider all comments 

received by the closing date and may 

amend the AD in light of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact with FAA 

personnel concerning this AD. Using the 

search function of our docket Web site, 

you can find and read the comments to 

any of our dockets, including the name 

of the individual who sent the 

comment. You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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 the 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); and 

3. 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. See the AD docket to examine 

the economic evaluation. 

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.

SUMMARY: This document publishes in 

the Federal Register an amendment 

adopting Emergency Airworthiness 

Directive (AD) 2010–12–51, which was 

sent previously to all known U.S. 

owners and operators of the specified 

Agusta model helicopters by individual 

letters. This AD requires, before further 

flight, removing the forward boot from 

the hub-locking nut (nut) and inserting 

a gauge between the tail rotor control 

rod (rod) and nut until the gauge stops. 

This AD then requires, depending on 

the depth measurement from the face of 

the nut, either reidentifying the tail 

rotor gearbox (TGB) with a new part 

number (P/N) or replacing the TGB and 

the associated parts with airworthy 

parts. This AD is prompted by a report 

of a missing rod bushing (bushing) from 

a 90-degree TGB installed on a Model 

AW119 MKII helicopter. The Agusta 

Model A119 helicopters also have the 

affected TGB installed; therefore, they 

are also included in the applicability of 

this AD. The actions specified by this 

AD are intended to detect a missing 

bushing in the TGB and to prevent 

abnormal vibration, damage to the tail 

rotor system, loss of the yaw control 

function, and subsequent loss of control 

of the helicopter. 

DATES: Effective September 17, 2010, to 

all persons except those persons to 

whom it was made immediately 

effective by Emergency AD 2010–12–51, 

issued on June 1, 2010, which contained 

the requirements of this amendment. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

17, 2010.
