can either limit the scope of your 

request so that it can be processed 

within the statutory time limit or agree 

to an alternative time frame for 

processing your request. In such cases, 

NCUA will make available its FOIA 

Public Liaison and notify the requester 

of the right to seek dispute resolution 

services from the Office of Government 

Information Services. 

■ 8. Revise § 792.17 to read as follows: 

§ 792.17 What can I do if the time limit 

passes and I still have not received a 

response? 

(a) If NCUA does not comply with the 

time limits under § 792.15, or as 

extended under § 792.16, you do not 

have to pay search fees; requesters 

qualifying for free search fees will not 

have to pay duplication fees. However, 

if NCUA has extended the time limits 

under § 792.16 and more than 5,000 

pages are necessary to respond to the 

request, NCUA may charge you search 

fees (or for requesters qualifying for free 

search fees, duplication fees), if NCUA 

has discussed with you via written mail, 

electronic mail, or telephone (or made 

not less than 3 good-faith attempts to do 

so) how you could effectively limit the 

scope of the request. 

(b) You can seek assistance from the 

FOIA Public Liaison or dispute 

resolution services from the Office of 

Government Information Services. You 

also can file suit against NCUA because 

you will be deemed to have exhausted 

your administrative remedies if NCUA 

fails to comply with the time limit 

provisions of this subpart. If NCUA can 

show that exceptional circumstances 

exist and that it is exercising due 

diligence in responding to your request, 

the court may retain jurisdiction and 

allow NCUA to complete its review of 

the records. You may have to pay search 

or duplication fees if a court has 

determined that exceptional 

circumstances exist and has extended 

the time limits for NCUA’s response by 

a court order. In determining whether 

exceptional circumstances exist, the 

court may consider your refusal to 

modify the scope of your request or 

arrange an alternative time frame for 

processing after being given the 

opportunity to do so by NCUA, when it 

notifies you of the existence of unusual 

circumstances as set forth in § 792.16. 

■ 9. In § 792.28, revise the introductory 

text to read as follows: 

§ 792.28 What if I am not satisfied with the 

response I receive? 

If you are not satisfied with NCUA’s 

response to your request, you can seek 

dispute resolution services from the 

FOIA Public Liaison and the Office of 

Government Information Services, and 

you can file an administrative appeal. 

Your appeal must be in writing and 

must be filed within 90 days from 

receipt of the initial determination (in 

cases of denials of the entire request or 

denials of a fee waiver or reduction), or 

from receipt of any records being made 

available pursuant to the initial 

determination (in cases of partial 

denials). In the response to your initial 

request, the Freedom of Information Act 

Officer or the Inspector General (or 

designee), will notify you that you may 

appeal any adverse determination to the 

Office of General Counsel. The General 

Counsel, or designee, as set forth in this 

paragraph, will:

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 787–8 airplanes. The NPRM 

published in the Federal Register on 

December 29, 2015 (80 FR 81220) (‘‘the 

NPRM’’). The NPRM was prompted by 

reports of electrical shorts of the motor 

stator wiring burning a hole through the 

housing of the motor of the CAC. The 

NPRM proposed to require installing 

modified inboard and outboard CAC 

modules on the LH side and RH side 

CACTCS packs. We are issuing this AD 

to prevent an electrical short from 

burning through the housing of the 

motor of the CAC. This condition, in 

combination with flammable fuel 

vapors, could result in a fire in the pack 

bay and consequent reduced 

controllability of the airplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 


Lhorne on DSK30JT082PROD with RULES
93796 Federal Register / Vol. 81, No. 246 / Thursday, December 22, 2016 / Rules and Regulations 

received on the NPRM and the FAA’s 

response to each comment. 

Support for the NPRM 

United Airlines (UA) stated that it 

agrees with the proposed compliance 

time. 

Request To Clarify the Unsafe 

Condition 

Boeing asked that we clarify the 

unsafe condition in the NPRM to specify 

that for a fire to occur in the pack bay, 

an electrical short would have to burn 

through the housing of the CAC motor 

in combination with the presence of 

flammable fluid vapors. Boeing stressed 

that the top-level event requires both an 

ignition source and flammable fluid 

vapors. 

We agree with the commenter’s 

request for the reason provided. We 

have revised the unsafe condition in the 

Discussion section and paragraph (e) of 

this AD accordingly. 

Requests To Increase Work-Hour 

Estimate 

Boeing and Japan Airlines (JAL) asked 

that we increase the work-hour estimate 

in the ‘‘Costs of Compliance’’ section of 

the NPRM. Boeing stated that Boeing 

Alert Service Bulletin B787–81205– 

SB210055–00, Issue 001, dated March 

12, 2015, specifies 25.25 work-hours for 

the LH side pack replacement and 28.25 

work-hours for the RH side pack 

replacement. Boeing added that the 

NPRM should either specify 30 workhours per side or 60 work-hours per 

airplane. JAL stated that the 

replacement for each pack specified in 

the proposed AD requires more than 25 

work-hours, as specified in the 

referenced service information. 

We agree. We have confirmed that the 

proposed work-hour estimate should be 

increased. Therefore, we have increased 

the work-hour estimate in the ‘‘Costs of 

Compliance’’ section of this final rule 

from ‘‘up to 30 work-hours’’ to ‘‘up to 

54 work-hours’’ for accomplishing the 

required actions. 

Request To Extend Compliance Time 

JAL asked that the proposed 

compliance time for the CAC 

replacements specified in the NPRM be 

extended so the actions can be done 

during scheduled heavy maintenance. 

JAL stated that the replacement for each 

pack specified in the proposed AD 

requires more than 25 work-hours, 

which would necessitate a longer 

compliance time. 

We do not agree with the commenter’s 

request to extend the compliance time 

for the CAC replacements. We have 

determined that the compliance time, as 

proposed, represents the maximum 

interval of time allowable for the 

affected airplanes to continue to safely 

operate before the CAC replacements are 

accomplished. Airplanes affected by 

this AD will undergo at least one 

maintenance check (C-check) within the 

required compliance time (5 years after 

the effective date of this AD); the 

replacement can be done at that time. 

Therefore, we have made no change to 

this AD in this regard. 

Request To Use Alternative Part 

Aeromexico asked if installing an H10 

CAC having part number (P/N) 

7010101H10 could be considered as an 

alternative to installing H09 CAC parts 

having P/N 7010101H09. Aeromexico 

stated that Boeing Alert Service Bulletin 

B787–81205–SB210055–00, Issue 001, 

dated March 12, 2015, specifies 

installing the H09 CAC, but UTC 

Aerospace Systems (the parts vendor) 

stated that there are no H09 CACs 

presently available. Aeromexico added 

that UTC Aerospace Systems indicated 

that H10 CACs having P/N 7010101H10 

will be available for retrofit during 2016. 

Aeromexico noted that Boeing and UTC 

Aerospace Systems have indicated that 

P/N 7010101H09 and P/N 7010101H10 

will be interchangeable. 

We agree that clarification is 

necessary. Future part designs might be 

acceptable as replacement parts for the 

part mandated by this AD, because 

those future parts should include design 

changes meant to address the unsafe 

condition identified in this AD. 

However, we do not agree to allow use 

of P/N 7010101H10 CACs, because P/N 

7010101H10 is not an approved part for 

installation on Model 787 airplanes at 

this time. Therefore, under the 

provisions of paragraph (h) of this AD, 

we will consider requests for approval 

of specific parts as an alternative 

method of compliance (AMOC) with 

this AD if data are submitted to 

substantiate that those parts would 

provide an acceptable level of safety. 

We have not revised this AD in this 

regard. 

Request To Clarify Certain Actions in 

Service Information 

UA asked that, for Group 1 airplanes 

in Work Packages 1 and 2 of the Work 

Instructions of Boeing Alert Service 

Bulletin B787–81205–SB210055–00, 

Issue 001, dated March 12, 2015, the 

steps identified as RC (Required for 

Compliance) be changed to refer to all 

applicable steps within that service 

information instead of referring to the 

actions specified in UTC Aerospace 

Systems Service Bulletins 7010188–21– 

6 and 7010189–21–6, both Revision 1, 

both dated January 30, 2015. UA stated 

that referring to the UTC Aerospace 

Systems service information forces 

operators to request multiple AMOCs in 

order to comply with the actions in the 

proposed AD. 

We agree that clarification is 

necessary. Although certain steps, 

which describe the access, removal, and 

installation of the CACs, are labeled as 

‘‘RC,’’ the specifics of how those actions 

are to be accomplished are not 

mandated. The Work Instructions in 

Boeing Alert Service Bulletin B787– 

81205–SB210055–00, Issue 001, dated 

March 12, 2015, do refer to UTC 

Aerospace Systems, Service Bulletins 

7010188–21–6 and 7010189–21–6, both 

Revision 1, both dated January 30, 2015, 

for accomplishing certain actions, but 

that service information is only an 

additional source of service information 

that operators may use (as indicated by 

the use of the words ‘‘refer to’’ in the RC 

step). 

UA asked that the UTC Aerospace 

Systems kit part number be called out 

in paragraph 3.A. under ‘‘Parts 

Necessary for Each Airplane,’’ in data 

module B787–A–21–00–0055–00A– 

934A–D, ‘‘Material Information,’’ of 

Boeing Alert Service Bulletin B787– 

81205–SB210055, Issue 001, dated 

March 12, 2015. UA noted that, as 

written, the proposed AD suggests that 

no parts are required. 

We do not agree with the commenter’s 

request. In Boeing Alert Service Bulletin 

B787–81205–SB210055, Issue 001, 

dated March 12, 2015; Step 3.A., ‘‘Parts 

Necessary for Each Airplane’’ for 

Groups 1 and 2 airplanes, within data 

module B787–A–21–00–0055–00A– 

934A–D, ‘‘Material Information,’’ 

identifies the parts necessary for each 

airplane that would be supplied by 

Boeing. Step 3.B. identifies the parts 

and materials that are supplied by 

operators. Although having all kit 

information in one location might 

provide a single list of parts needed, it 

could be confusing to determine who is 

responsible for supplying which parts. 

Therefore, we have made no change to 

this AD in this regard. 

UA pointed out several instances 

where Boeing Alert Service Bulletin 

B787–81205–SB210055, Issue 001, 

dated March 12, 2015, is referenced for 

certain sealing and bonding check 

instructions. UA stated that UTC 

Aerospace Systems Service Bulletins 

7010188–21–6 and 7010189–21–6, both 

Revision 1, both dated January 30, 2015, 

refer back to Boeing Alert Service 

Bulletin B787–81205–SB210055, Issue 

001, dated March 12, 2015, which does 

not provide guidance on how to 

accomplish these actions. From these 


Lhorne on DSK30JT082PROD with RULES
Federal Register / Vol. 81, No. 246 / Thursday, December 22, 2016 / Rules and Regulations 93797 

statements, we infer that UA is 

requesting that we revise the proposed 

requirements to clarify how these 

actions are to be accomplished. 

We find that clarification is necessary. 

The Work Instructions in Boeing Alert 

Service Bulletin B787–81205– 

SB210055, Issue 001, dated March 12, 

2015, specify ‘‘The electrical surface 

bond and fay seal data is provided in 

the applicable 787 airplane maintenance 

manual (AMM) 21–51–19, Cabin Air 

Compressor—Preparation Before 

Installation AMMs.’’ The instructions 

are contained within those AMM 

procedures; however, those steps are not 

required for compliance with this AD 

because alternative procedures may be 

used. Therefore, we have made no 

change to this AD in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin B787–81205–SB210055–00, 

Issue 001, dated March 12, 2015. This 

service information describes 

procedures for installing modified 

inboard and outboard CAC modules on 

the LH side and RH side CACTCS packs. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

Costs of Compliance 

We estimate that this AD affects 22 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Modification, installation, and 

installation test.

Up to 54 work-hours × $85 

per hour = $4,590.

$0 Up to $4,590 .......................... Up to $100,980. 

According to the manufacturer, 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 for 

affected individuals. As a result, we 

have included all costs in our cost 

estimate. 

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, and 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 

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 this AD: 

(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), 

(3) Will not affect intrastate aviation 

in Alaska, 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.

Airworthiness Directives; Viking Air

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Viking Air Limited Models DHC–2 Mk. 

I, DHC–2 Mk. II, and DHC–2 Mk. III 

airplanes that supersedes AD 2016–19– 

08. This AD results from mandatory 

continuing airworthiness information 

(MCAI) issued by the aviation authority 

of another country to identify and 

correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as corrosion of the 

elevator control rod and of the elevator 

actuating lever on the control column, 

which could cause these components to 

fail. We are issuing this AD to require 

actions to address the unsafe condition 

on these products. 

DATES: This AD is effective December 

22, 2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 24, 2016 (81 FR 64053, 

September 19, 2016). 

We must receive comments on this 

AD by February 6, 2017.
