AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

As a result of fatigue-testing programme on 

Jetstream aeroplanes, cracks have been found 

on the main landing gear (MLG) fittings that 

embody modifications JM5218 or JM8003. 

This condition, if not detected and 

corrected, could lead to a MLG collapse on 

the ground or during landing, possibly 

resulting in a fuel tank rupture, consequent 

damage to the aeroplane or injury to the 

occupants. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

22, 2011. 

On June 22, 2011, the Director of the 

Federal Register approved the 

incorporation by reference of a certain 

publication listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

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 was published in the Federal 

Register on March 16, 2011 (76 FR 

14349). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

As a result of fatigue-testing programme on 

Jetstream aeroplanes, cracks have been found 

on the main landing gear (MLG) fittings that 

embody modifications JM5218 or JM8003. 

This condition, if not detected and 

corrected, could lead to a MLG collapse on 

the ground or during landing, possibly 

resulting in a fuel tank rupture, consequent 

damage to the aeroplane or injury to the 

occupants. 

Analysis of this failure indicates that an 

inspection regime has to be implemented in 

order to ensure the safe operation of the MLG 

beyond the accumulation of 41,000 Flight 

Cycles (FC). 

For the reasons described above, this AD 

requires initial and repetitive eddy current 

inspections, and depending on findings, 

accomplishment of corrective actions. 

The MCAI requires replacing or 

repairing any cracked MLG fitting found 

during the initial and repetitive 

inspections. You may obtain further 

information by examining the MCAI in 

the AD docket 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow FAA policies. 

Any such differences are highlighted in 

a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

190 products of U.S. registry. We also 

estimate that it will take about 20 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $323,000 or $1,700 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 4 work-hours and require parts 

costing $8,000, for a cost of $8,340 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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

28636 Federal Register / Vol. 76, No. 96 / Wednesday, May 18, 2011 / Rules and Regulations 

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 above, I 

certify 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); 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 a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD Docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

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. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2011–11–01 British Aerospace Regional 

Aircraft: Amendment 39–16699; Docket 

No. FAA–2011–0230; Directorate 

Identifier 2011–CE–004–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective June 22, 2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to British Aerospace 

Regional Aircraft Model HP.137 Jetstream 

Mk.1, Jetstream Series 200, Jetstream Series 

3101, and Jetstream Model 3201 airplanes, all 

serial numbers, that are: 

(1) Equipped with main landing gear 

(MLG) fittings, part number (P/N) 

1379133B1/B2/B3/B4 that incorporate 

Modifications JM5218 or JM8003; and 

(2) Certificated in any category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 32: Landing Gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

As a result of fatigue-testing programme on 

Jetstream aeroplanes, cracks have been found 

on the main landing gear (MLG) fittings that 

embody modifications JM5218 or JM8003. 

This condition, if not detected and 

corrected, could lead to a MLG collapse on 

the ground or during landing, possibly 

resulting in a fuel tank rupture, consequent 

damage to the aeroplane or injury to the 

occupants. 

Analysis of this failure indicates that an 

inspection regime has to be implemented in 

order to ensure the safe operation of the MLG 

beyond the accumulation of 41 000 Flight 

Cycles (FC). 

For the reasons described above, this AD 

requires initial and repetitive eddy current 

inspections, and depending on findings, 

accomplishment of corrective actions. 

The MCAI requires replacing or repairing any 

cracked MLG fitting found during the initial 

and repetitive inspections. You may obtain 

further information by examining the MCAI 

in the AD docket. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) Upon accumulating 41,000 flight cycles 

(landings) on the MLG since first installation 

or within the next 2,000 flight cycles 

(landings) on the MLG after June 22, 2011 

(the effective date of this AD), whichever 

occurs later, eddy current inspect all the 

MLG leg pivot beam fastener bores for cracks. 

Do the inspections following British 

Aerospace Jetstream Series 3100 & 3200 

Service Bulletin 32–JA090240, Revision 1, 

dated January 18, 2010. 

(2) Before further flight after any inspection 

required in paragraphs (f)(1), (f)(2)(i), 

(f)(2)(ii), and (f)(3) of this AD in which cracks 

are found, replace the MLG fitting or repair 

any cracks. Cracks are defined in paragraph 

2.D.(4) of British Aerospace Jetstream Series 

3100 & 3200 Service Bulletin 32–JA090240, 

Revision 1, dated January 18, 2010. Replace 

or repair the MLG fitting following British 

Aerospace Jetstream Series 3100 & 3200 

Service Bulletin 32–JA090240, Revision 1, 

dated January 18, 2010. Any time the MLG 

fitting is repaired or replaced, do the 

following actions as applicable: 

(i) MLG fitting is replaced with a new MLG 

fitting as specified in paragraph (f)(2) of this 

AD: Upon accumulating 41,000 flight cycles 

(landings) after replacement, eddy current 

inspect all the MLG leg pivot beam fastener 

bores for cracks. Do the inspections following 

British Aerospace Jetstream Series 3100 & 

3200 Service Bulletin 32–JA090240, Revision 

1, dated January 18, 2010. 

(ii) MGL fitting is repaired as specified in 

paragraph (f)(2) of this AD: Upon 

accumulating 27,000 flight cycles (landings) 

after the last repair and repetitively thereafter 

at intervals not to exceed 27,000 flight cycles 

(landings), eddy current inspect all the MLG 

leg pivot beam fastener bores for cracks. Do 

the inspections following British Aerospace 

Jetstream Series 3100 & 3200 Service Bulletin 

32–JA090240, Revision 1, dated January 18, 

2010. 

(3) If no cracks are found during any 

inspection required in paragraph (f)(1), 

(f)(2)(i), or (f)(2)(ii) of this AD, repetitively 

thereafter upon accumulating 27,000 flight 

cycles (landings) after the last inspection, 

eddy current inspect all the MLG leg pivot 

beam fastener bores for cracks. 

(4) As of June 22, 2011 (the effective date 

of this AD), only install a MLG fitting 

specified in paragraph (c)(1) of this AD that 

has been eddy current inspected and found 

free of cracks following British Aerospace 

Jetstream Series 3100 & 3200 Service Bulletin 

32–JA090240, Revision 1, dated January 18, 

2010. 

(5) Some of the compliance times of this 

AD are presented in flight cycles (landings). 

If the total flight cycles have not been kept, 

multiply the total number of airplane hours 

time-in-service by 0.75. For the purposes of 

this AD: 

(i) 75 cycles equals 100 hours TIS; and 

(ii) 750 cycles equals 1,000 hours TIS. 

Note 1: Credit will be given for the 

inspection required in paragraph (f)(1) of this 

AD and the corrective action required in 

paragraph (f)(2) of this AD if already done 

before June 22, 2011 (the effective date of this 

AD) following British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 32–

and EC130 B4 Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

specified Eurocopter France (ECF) 

helicopters. This AD results from a 

mandatory continuing airworthiness 

information (MCAI) AD issued by the 

aviation authority of the European 

Aviation Safety Agency (EASA), which 

is the Technical Agent for the Member 

States of the European Community. The 

superseding MCAI AD states that 

several engine flameouts have involved 

failure of the 41-tooth pinion in the 

engine accessory gearbox. Each affected 

helicopter had a starter-generator 

manufactured by one company. 

Investigation revealed the torque 

damping system of the starter-generator 

was inoperative due to incorrect 

adjustment that caused bending stresses 

on the 41-tooth pinion. Failure of the 

pinion causes the engine fuel pump to 

stop operating, resulting in an engine 

flameout. The EASA AD requires a new 

adjustment procedure to optimize the 

performance of the specified startergenerator damping assembly. This AD is 

intended to prevent failure of a pinion 

and a fuel pump, engine flameout, and 

subsequent loss of control of the 

helicopter. 

DATES: This AD becomes effective on 

June 22, 2011. 

The incorporation by reference of 

certain publications is approved by the 

Director of the Federal Register as of 

June 22, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified ECF helicopters 

on December 6, 2010. That NPRM was 

published in the Federal Register on 

December 21, 2010 (75 FR 79988). That 

NPRM proposed to require within 110 

hours time-in-service or 3 months, 

whichever occurs first: 

• Modifying and marking the Aircraft 

Parts Corporation (APC) starter 

generator; and 

• Before installing an APC startergenerator with a part number (P/N) of 

150SG122Q or 200SGL130Q, complying 

with the requirements of the proposed 

AD. 

You may obtain further information 

by examining the MCAI AD and any 

related service information in the AD 

docket.
