6578 Federal Register / Vol. 76, No. 25 / Monday, February 7, 2011 / Proposed Rules 

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 

removing Amendment 39–12651 (67 FR 

6855, February 14, 2002) and adding the 

following new AD: 

BAE Systems (Operations) Limited: Docket 

No. FAA–2010–0673; Directorate 

Identifier 2009–NM–208–AD. 

Comments Due Date 

(a) We must receive comments by March 

24, 2011. 

Affected ADs 

(b) The AD supersedes AD 2002–03–10, 

Amendment 39–12651. 

Applicability 

(c) This AD applies to BAE Systems 

(Operations) Limited Model BAe 146–100A, 

–200A, and –300A airplanes and Model Avro 

146–RJ70A, 146–RJ85A, and 146–RJ100A 

airplanes; certificated in any category; all 

serial numbers. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 32: Landing Gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

In June 2000, prompted by a crack found 

at the top of the Nose Landing Gear (NLG) 

oleo, BAE Systems (Operations) Ltd (BAE 

Systems) issued Inspection Service Bulletin 

(ISB) ISB.32–158. * * * 

Later, as part of an accident investigation, 

the examination of a fractured NLG main 

fitting showed that M–D (Messier-Dowty) 

SB.146–32–150 was not accomplished * * * 

BAE Systems determined that more NLG 

units could be similarly affected. * * * 

Subsequently, investigation and analysis 

by M–D identified the need for a reduction 

of the inspection threshold and the repetitive 

inspection interval for the affected NLG 

units. * * * 

* * * * * 

* * * [I]nvestigation by M–D showed that 

if any undetected crack was present at the 

time of the embodiment of M–D SB 146–32– 

150, Part B or Part C, it could continue to 

grow while the NLG is in service and could 

lead to the failure of the main fitting and 

possible collapse of the NLG. * * * [B]AE 

Systems have received additional reports of 

cracked NLG main fittings. One operator 

reported a crack in a premodification main 

fitting. * * * 

* * * * * 

Undetected cracks could lead to failure of 

the NLG Main Fitting and collapse of the 

NLG. 

* * * * * 

The unsafe condition is cracking of the 

NLG, which could adversely affect the 

airplane’s safe landing. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Inspection 

(g) Before the accumulation of 5,000 total 

flight cycles on the NLG main fitting, or 

within 300 flight cycles after the effective 

date of this AD, whichever occurs later, do 

an ultrasonic inspection on the upper part of 

the NLG main fitting for any crack, in 

accordance with the Accomplishment 

Instructions of Messier-Dowty Service 

Bulletin 146–32–174, Revision 2, including 

Appendix A, dated August 16, 2010. 

Thereafter, repeat the inspection at intervals 

not to exceed 300 flight cycles. 

(h) An inspection that has been done in 

accordance with the Accomplishment 

Instructions of Messier-Dowty Service 

Bulletin 146–32–174, Revision 1, dated 

September 2, 2009, or in accordance with the 

Accomplishment Instructions of MessierDowty Service Bulletin 146–32–175, 

Revision 2, dated March 5, 2010, before the 

effective date of this AD but not more than 

300 flight cycles before the effective date of 

this AD, is considered acceptable for 

compliance with the initial inspection 

required by paragraph (g) of this AD. 

Replacement 

(i) If any crack is found from the 

inspections required by paragraph (g) of this 

AD, before further flight, replace the NLG 

main fitting with a serviceable NLG main 

fitting, using a method approved by the 

Manager, International Branch, ANM–116, 

Transport Airplane Directorate, FAA; or the 

European Aviation Safety Agency (EASA) (or 

its delegated agent). 

Note 1: Guidance on replacing the NLG 

main fitting with a serviceable NLG main 

fitting can be found in Subsection 32–20–11 

of BAE Systems (Operations) Limited BAe 

146 Series/Avro 146–RJ Series Aircraft 

Maintenance Manual 146.153, Revision 101, 

dated July 15, 2010. 

(j) Replacing the NLG main fitting with a 

serviceable NLG main fitting is not a 

terminating action for the repetitive 

inspections required by paragraph (g) of this 

AD. 

Parts Installation 

(k) As of the effective date of this AD, no 

person may install an affected NLG main 

fitting on any airplane, unless that NLG main 

fitting has been inspected in accordance with 

paragraph (g) of this AD and no cracking is 

found.

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

NPRM for the products listed above. 

This action revises the earlier NPRM by 

expanding the scope. This proposed AD 

results from mandatory continuing 

airworthiness information (MCAI) 

originated 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: 

* * * * *

Federal Register / Vol. 76, No. 25 / Monday, February 7, 2011 / Proposed Rules 6579 

(CMR) are given in Airbus A330 ALS Part 3, 

which is approved by the European Aviation 

Safety Agency (EASA). 

The revision 03 of Airbus A330 ALS Part 

3 introduces more restrictive maintenance 

requirements and/or airworthiness 

limitations. Failure to comply with this 

revision constitutes an unsafe condition. 

* * * * * 

The unsafe condition is safetysignificant latent failures that would, in 

combination with one or more other 

specific failures or events, result in a 

hazardous or catastrophic failure 

condition. The proposed AD would 

require actions that are intended to 

address the unsafe condition described 

in the MCAI.

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an 

airworthiness directive (AD) that would 

apply to certain Model A330–200 and 

–300 series airplanes. That 

supplemental NPRM was published in 

the Federal Register on August 4, 2010 

(75 FR 46861). The original NPRM (75 

FR 4710, January 29, 2010) proposed to 

require actions intended to address the 

unsafe condition for the products listed 

above. The supplemental NPRM 

introduced new or more restrictive 

maintenance requirements and/or 

airworthiness limitations as specified in 

Airbus A330 ALS, Part 3—Certification 

Maintenance Requirements, Revision 

02, dated December 16, 2009. 

Since that supplemental NPRM was 

issued, we have received Airbus A330 

ALS, Part 3—Certification Maintenance 

Requirements, Revision 03, dated July 

29, 2010, which contains new and more 

restrictive requirements. We referred to 

Airbus A330 ALS, Part 3—Certification 

Maintenance Requirements, Revision 

02, dated December 16, 2009, as the 

appropriate source of service 

information in the original NPRM. We 

have revised this second supplemental 

NPRM to refer to Airbus A330 ALS, Part 

3—Certification Maintenance 

Requirements, Revision 03, dated July 

29, 2010. The European Aviation Safety 

Agency (EASA) has issued EASA AD 

2010–0264, dated December 20, 2010. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We have considered the following 

comment received on the first 

supplemental NPRM. 

Request To Revise Paragraphs (f) and 

(g) of the First Supplemental NPRM 

Airbus requested that we revise 

paragraphs (f) and (g) of the first 

supplemental NPRM. Airbus stated that 

Section 25.1529 of the Federal Aviation 

Regulations (14 CFR 25.1529) and 

Appendix H of 14 CFR part 25 require 

the airplane type certificate holder—not 

the operator—to produce and update the 

Instructions for Continued 

Airworthiness (ICA). Airbus stated that 

the type certificate holder must make 

the ICAs available to all operators and 

owners, who are then responsible to 

incorporate the latest applicable 

contents of revisions of the 

Airworthiness Limitations section (ALS) 

or any other part of the ICA into the 

approved maintenance program. Airbus 

stated that operators and owners 

demonstrate compliance with Section 

121.367 of the Federal Aviation 

Regulations (14 CFR 121.367) and 

Section 121.369 of the Federal Aviation 

Regulations (14 CFR 121.369) by 

following this procedure. 

We agree that the ALI requirement 

could be stated more clearly so that it 

does not directly require operators to 

revise the ALS of the ICA. It is more 

appropriate to require revising the 

operators’ maintenance programs. 

However, we have not revised 

paragraph (f) of this second 

supplemental NPRM because it is a 

restatement of the existing AD. We have 

revised paragraph (g) of this second 

supplemental NPRM to clarify that that 

the operators and owners are required to 

incorporate the latest applicable 

contents of revisions of the ALS into the 

maintenance program. 

Change to Applicability 

We have also added Airbus Model 

A330–223F and A330–243F airplanes to 

the applicability of this supplemental 

NPRM. There are no Model A330–223F 

and A330–243F airplanes on the U.S. 

registry. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 


wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
6580 Federal Register / Vol. 76, No. 25 / Monday, February 7, 2011 / Proposed Rules 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Certain changes described above 

expand the scope of the earlier NPRM. 

As a result, we have determined that it 

is necessary to reopen the comment 

period to provide additional 

opportunity for the public to comment 

on this proposed AD. 

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 proposed 

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 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 55 products of U.S. registry. 

The actions that are required by AD 

2007–05–08 and retained in this 

proposed AD take about 1 work-hour 

per product, at an average labor rate of 

$85 per work hour. Based on these 

figures, the estimated cost of the 

currently required actions is $85 per 

product. 

We estimate that it would take about 

1 work-hour per product to comply with 

the new basic requirements of this 

proposed AD. The average labor rate is 

$85 per work-hour. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$4,675, or $85 per product. 

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); 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 proposed AD and placed it in the 

AD docket. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 

removing Amendment 39–14969 (72 FR 

9658, March 5, 2007) and adding the 

following new AD: 

Airbus: Docket No. FAA–2009–1212; 

Directorate Identifier 2008–NM–167–AD. 

Comments Due Date 

(a) We must receive comments by March 4, 

2011. 

Affected ADs 

(b) This AD supersedes AD 2007–05–08, 

Amendment 39–14969. 

Applicability 

(c) This AD applies to all Airbus Model 

A330–201, –202, –203, –223, –223F, –243, 

–243F, –301, –302, –303, –321, –322, –323, 

–341, –342, and –343 airplanes, certificated 

in any category; all serial numbers. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 05. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

* * * * * 

The airworthiness limitations applicable to 

the Certification Maintenance Requirements 

(CMR) are given in Airbus A330 ALS Part 3, 

which is approved by the European Aviation 

Safety Agency (EASA). 

The revision 03 of Airbus A330 ALS Part 

3 introduces more restrictive maintenance 

requirements and/or airworthiness 

limitations. Failure to comply with this 

revision constitutes an unsafe condition. 

* * * * * 

The unsafe condition is safety-significant 

latent failures that would, in combination 

with one or more other specific failures or 

events, result in a hazardous or catastrophic 

failure condition. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new inspections. Compliance with 

these inspections is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by these inspections, the 

operator may not be able to accomplish the 

inspections described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval for an 

alternative method of compliance according 

to paragraph (k) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued damage tolerance of the affected 

structure. The FAA has provided guidance 

for this determination in Advisory Circular 

(AC) 25–1529–1A. 

Restatement of Requirements of AD 2007– 

05–08, With Requirements for Model A340 

Airplanes Removed 

Revise the Airworthiness Limitations Section 

of the Instructions for Continued 

Airworthiness 

(f) Unless already done: Within 90 days 

after April 9, 2007 (the effective date of AD 

2007–05–08), revise the Airworthiness 

Limitations section of the Instructions for 

Continued Airworthiness by incorporating 

Airbus A330 Certification Maintenance 

Requirements, Document 955.2074/93, Issue 

19, dated March 22, 2006. Accomplish the 

actions specified in the applicable CMR at 

the times specified in the applicable CMR 

and in accordance with the applicable CMR, 

except as provided by paragraphs (f)(1) and

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated 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: 

[T]he FAA has published SFAR 88 (Special 

Federal Aviation Regulation 88). 

In their letters referenced 04/00/02/07/01– 

L296, dated March 4th, 2002, and 04/00/02/ 

07/03–L024, dated February 3rd, 2003, the 

JAA [Joint Aviation Authorities] 

recommended the application of a similar 

regulation to the National Aviation 

Authorities (NAA). 

Under this regulation, all holders of type 

certificates for passenger transport aircraft 

* * * are required to conduct a design 

review against explosion risks. 

During improvement of the protection of 

fuel pump wiring against short-circuit by 

accomplishment of Airbus Service Bulletin 

(SB) A300–24–6094, a study led by the 

manufacturer concluded that the harness, 

installed through the wing panel needed to 

be protected to prevent possible damage in 

case of chafing which could potentially lead 

to short-circuit [and intermittent function or 

loss of the inner tank fuel pump. Loss of both 

inner tank fuel pumps could result in 

inability to use the remaining fuel supply in 

the inner tank. A short-circuit could also 

result in an ignition source in a flammable 

leakage zone]. 

* * * * * 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI.
