the access and amendment provisions. If 

an agency claims an exemption, 

however, it must issue a Notice of 

Proposed Rulemaking to make clear to 

the public the reasons why a particular 

exemption is claimed. 

DHS is claiming exemptions from 

certain requirements of the Privacy Act 

for DHS/OPS—003 Operations 

Collection, Planning, Coordination, 

Reporting, Analysis, and Fusion System 

of Records. Some information in DHS/ 

OPS—003 Operations Collection, 

Planning, Coordination, Reporting, 

Analysis, and Fusion System of Records 

relates to official DHS national security, 

law enforcement, immigration, and 

intelligence activities. These 

exemptions are needed to protect 

information relating to DHS activities 

from disclosure to subjects or others 

related to these activities. Specifically, 

the exemptions are required to preclude 

subjects of these activities from 

frustrating these processes; to avoid 

disclosure of activity techniques; to 

protect the identities and physical safety 

of confidential informants and law 

enforcement personnel; to ensure DHS’ 

ability to obtain information from third 

parties and other sources; to protect the 

privacy of third parties; and to safeguard 

classified information. Disclosure of 

information to the subject of the inquiry 

could also permit the subject to avoid 

detection or apprehension. 

The exemptions proposed here are 

standard law enforcement and national 

security exemptions exercised by a large 

number of federal law enforcement and 

intelligence agencies. In appropriate 

circumstances, where compliance 

would not appear to interfere with or 

adversely affect the law enforcement 

purposes of this system and the overall 

law enforcement process, the applicable 

exemptions may be waived on a case by 

case basis. 

List of Subjects in 6 CFR Part 5 

Freedom of information; Privacy. 

For the reasons stated in the 

preamble, DHS proposes to amend 

Chapter I of Title 6, Code of Federal 

Regulations, as follows: 

PART 5—DISCLOSURE OF RECORDS 

AND INFORMATION 

1. The authority citation for part 5 

continues to read as follows: 

Authority: 6 U.S.C. 101 et seq.; Pub. L. 

107–296, 116 Stat. 2135; 5 U.S.C. 301. 

Subpart A also issued under 5 U.S.C. 552. 

Subpart B also issued under 5 U.S.C. 552a. 

2. Add at the end of Appendix C to 

Part 5, the following new paragraph 

‘‘53’’: 

Appendix C to Part 5—DHS Systems of 

Records Exempt From the Privacy Act 

* * * * * 

53. The DHS/OPS—003 Operations 

Collection, Planning, Coordination, 

Reporting, Analysis, and Fusion System of 

Records consists of electronic and paper 

records and will be used by DHS/OPS. The 

DHS/OPS—003 Operations Collection, 

Planning, Coordination, Reporting, Analysis, 

and Fusion System of Records is a repository 

of information held by DHS in connection 

with its several and varied missions and 

functions, including, but not limited to: the 

enforcement of civil and criminal laws; 

investigations, inquiries, and proceedings 

there under; national security and 

intelligence activities. The DHS/OPS—003 

Operations Collection, Planning, 

Coordination, Reporting, Analysis, and 

Fusion System of Records contains 

information that is collected by, on behalf of, 

in support of, or in cooperation with DHS 

and its components and may contain 

personally identifiable information collected 

by other federal, state, local, tribal, foreign, 

or international government agencies. 

The Secretary of Homeland Security is 

exempting this system from the following 

provisions of the Privacy Act, subject to 

limitations set forth in 5 U.S.C. 552a(c)(3); 

(d); (e)(1), (e)(4)(G), (e)(4)(H), (e)(4)(I); and (f) 

pursuant to 5 U.S.C. 552a (k)(1), (k)(2), and 

(k)(3). Exemptions from these particular 

subsections are justified, on a case-by-case 

basis to be determined at the time a request 

is made, for the following reasons: 

(a) From subsection (c)(3) (Accounting for 

Disclosures) because release of the 

accounting of disclosures could alert the 

subject of an investigation of an actual or 

potential criminal, civil, or regulatory 

violation to the existence of that investigation 

and reveal investigative interest on the part 

of DHS as well as the recipient agency. 

Disclosure of the accounting would therefore 

present a serious impediment to law 

enforcement efforts and/or efforts to preserve 

national security. Disclosure of the 

accounting would also permit the individual 

who is the subject of a record to impede the 

investigation, to tamper with witnesses or 

evidence, and to avoid detection or 

apprehension, which would undermine the 

entire investigative process. 

(b) From subsection (d) (Access to Records) 

because access to the records contained in 

this system of records could inform the 

subject of an investigation of an actual or 

potential criminal, civil, or regulatory 

violation to the existence of that investigation 

and reveal investigative interest on the part 

of DHS or another agency. Access to the 

records could permit the individual who is 

the subject of a record to impede the 

investigation, to tamper with witnesses or 

evidence, and to avoid detection or 

apprehension. Amendment of the records 

could interfere with ongoing investigations 

and law enforcement activities and would 

impose an unreasonable administrative 

burden by requiring investigations to be 

continually reinvestigated. In addition, 

permitting access and amendment to such 

information could disclose security-sensitive 

information that could be detrimental to 

homeland security. 

(c) From subsection (e)(1) (Relevancy and 

Necessity of Information) because in the 

course of investigations into potential 

violations of federal law, the accuracy of 

information obtained or introduced 

occasionally may be unclear, or the 

information may not be strictly relevant or 

necessary to a specific investigation. In the 

interests of effective law enforcement, it is 

appropriate to retain all information that may 

aid in establishing patterns of unlawful 

activity. 

(d) From subsections (e)(4)(G), (e)(4)(H), 

and (e)(4)(I) (Agency Requirements) and (f) 

(Agency Rules), because portions of this 

system are exempt from the individual access 

provisions of subsection (d) for the reasons 

noted above, and therefore DHS is not 

required to establish requirements, rules, or 

procedures with respect to such access. 

Providing notice to individuals with respect 

to existence of records pertaining to them in 

the system of records or otherwise setting up 

procedures pursuant to which individuals 

may access and view records pertaining to 

themselves in the system would undermine 

investigative efforts and reveal the identities 

of witnesses, and potential witnesses, and 

confidential informants.

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: 

The flight crew of a F28 Mark 0070 (Fokker 

70) aeroplane received a MLG [main landing 

gear] unsafe message after landing gear down 

selection during approach. * * *

Inspection just after landing revealed a lot 

of ice near the LH (left-hand) MLG downlock 

actuator. * * * 

Based on the quantity and location of the 

ice, it is considered highly likely that the ice 

had formed between the upper end of the 

downlock actuator and the upper side brace, 

and was accumulated during taxi on slushand snow-contaminated taxiways and 

runway at the departure airport. 

Ice in this location prevents the actuator 

from turning freely relative to the upper side 

brace during landing gear down selection, 

likely resulting in failure of the piston rod. 

This condition, if not corrected, could lead 

to further cases of MLG extension problems, 

possibly resulting in loss of control of the 

aeroplane during landing roll-out.

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2009–0268, 

dated December 17, 2009 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

The flight crew of a F28 Mark 0070 (Fokker 

70) aeroplane received a MLG [main landing 

gear] unsafe message after landing gear down 

selection during approach. After cycling the 

landing gear, only a LH [left-hand] MLG 

unsafe indication remained. A go-around was 

initiated and alternate landing gear down 

selection was performed twice, but the LH 

MLG did not lock down. During final 

approach, without further flight crew action, 

all 3 green lights illuminated and an 

uneventful landing was made. 

Inspection just after landing revealed a lot 

of ice near the LH MLG downlock actuator. 

Further investigation revealed that the piston 

rod of the downlock actuator had failed at the 

threaded end close to the eye end, which is 

attached to the lower lock link, and that the 

piston rod was broken in an overload by 

bending in the neck close to the threaded 

end. 

Based on the quantity and location of the 

ice, it is considered highly likely that the ice 

had formed between the upper end of the 

downlock actuator and the upper side brace, 

and was accumulated during taxi on slushand snow-contaminated taxiways and 

runway at the departure airport. 

Ice in this location prevents the actuator 

from turning freely relative to the upper side 

brace during landing gear down selection, 

likely resulting in failure of the piston rod. 

This condition, if not corrected, could lead 

to further cases of MLG extension problems, 

possibly resulting in loss of control of the 

aeroplane during landing roll-out. 

To address this unsafe condition and 

prevent the accumulation of water, slush 

and/or snow, Goodrich, the MLG 

manufacturer, has introduced a new upper 

side brace, Part Number (P/N) 41350–3, 

which has two additional drain holes. 

Goodrich Service Bulletin (SB) 41350–32–25 

describes the modification of the P/N 41350– 

1 MLG upper side brace, introducing the two 

additional drain holes and consequent reidentification of the part to P/N 41350–3. 

For the reasons described above, this AD 

requires modification of both (LH and RH 

[right-hand]) P/N 41350–1 MLG upper side 

braces, or replacement of the P/N 41350–1 

upper side braces with modified P/N 41350– 

3 upper side braces. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Fokker Services B.V. has issued 

Service Bulletin SBF100–32–157, 

Revision 1, dated October 7, 2009. 

Goodrich Corporation has issued 

Service Bulletin 41350–32–25, dated 

January 30, 2009. The actions described 

in the service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

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 

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. 


hsrobinson on DSK69SOYB1PROD with PROPOSALS
69608 Federal Register / Vol. 75, No. 219 / Monday, November 15, 2010 / Proposed Rules 

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 6 products of U.S. registry. 

We also estimate that it would take 

about 16 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

Where the service information lists 

required parts costs that are covered 

under warranty, we have assumed that 

there will be no charge for these costs. 

As we do not control warranty coverage 

for affected parties, some parties may 

incur costs higher than estimated here. 

Based on these figures, we estimate the 

cost of the proposed AD on U.S. 

operators to be $8,160, or $1,360 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.

Applicability 

(c) This AD applies to Fokker Services B.V. 

Model F.28 Mark 0070 and 0100 airplanes, 

certificated in any category; all serial 

numbers, if equipped with Goodrich 

(formerly Menasco, Colt Industries) main 

landing gears (MLGs) fitted with MLG upper 

side braces having part number (P/N) 41350– 

1. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 32: Landing Gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

The flight crew of a F28 Mark 0070 (Fokker

Based on the quantity and location of the 

ice, it is considered highly likely that the ice 

had formed between the upper end of the 

downlock actuator and the upper side brace, 

and was accumulated during taxi on slushand snow-contaminated taxiways and 

runway at the departure airport. 

Ice in this location prevents the actuator 

from turning freely relative to the upper side 

brace during landing gear down selection, 

likely resulting in failure of the piston rod. 

This condition, if not corrected, could lead 

to further cases of MLG extension problems, 

possibly resulting in loss of control of the 

aeroplane during landing roll-out.

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: 

During flight-testing of a wing anti-ice 

piccolo tube containing a deliberate small 

breach, it was determined that the wing 

leading edge thermal switches Part Number 

(P/N) 601R59320–1 were not detecting the 

consequent bleed leak at the design 

threshold. As a result, Airworthiness 

Limitation (AWL) tasks, consisting of a 

functional check of the wing leading edge 

thermal switches (P/N 601R59320–1) and an 

inspection of the wing anti-ice duct piccolo 

tubes on aeroplanes with these switches 

installed, have been introduced. These tasks 

will limit exposure to dormant failure of the 

wing leading edge thermal switches in the 

event of piccolo tube failure, which could 

potentially compromise the structural 

integrity of the wing leading edge and the 

effectiveness of the wing anti-ice system. 

* * * * * 

The unsafe condition is loss of control 

of the airplane. The proposed AD would 

require actions that are intended to 

address the unsafe condition described 

in the MCAI. 

DATES: We must receive comments on 

this proposed AD by December 30,
