Download as PDF Federal Register / Vol. 81, No. 70 / Tuesday, April 12, 2016 / Proposed Rules DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2016–5578; Directorate Identifier 2016–CE–005–AD] RIN 2120–AA64 Airworthiness Directives; Pacific Aerospace Limited Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL (type certificate previously held by Pacific Aerospace Corporation Ltd.) airplanes that would supersede AD 2006–13–05. 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 some critical rivets on the wing not being fully age-hardened and being installed in specific locations where reduction in rivet strength reduces wing strength. We are issuing this proposed AD to require actions to address the unsafe condition on these products. SUMMARY: We must receive comments on this proposed AD by May 27, 2016.

SUPPLEMENTARY INFORMATION: 21489 Since we issued AD 2006–13–05, additional airplanes have been identified that need to be added to the applicability of the AD. The Civil Aviation Authority (CAA), which is the aviation authority for New Zealand, has issued AD No. DCA/ 750XL/7B, dated February 25, 2016 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: DCA/750XL/7B revised to introduce PACSB/XL/018 issue 4, dated 20 January 2016, which reduces the applicability to S/ N 101 through to 131 with no change to the requirements. Aircraft with S/N 132 onwards have been modified in accordance with PACSB/XL/018 at manufacture, which is a terminating action for the requirements of this AD. This proposed AD would require you to remove rivets that have not been fully age hardened and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength affects overall structural capability. The proposed AD would retain the airplane weight AFM limitations until the rivets are replaced with the bolts, washers, and nuts. You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2016–5578. Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2016–5578; Directorate Identifier 2016–CE–005–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. FAA’s Determination and Requirements of the Proposed AD Discussion On June 12, 2006, we issued AD 2006–13–05, Amendment 39–14658 (71 FR 35509, June 21, 2006) (‘‘AD 2006– 13–05’’). That AD required actions intended to address an unsafe condition on certain Pacific Aerospace Corporation Ltd. Model 750XL airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 Related Service Information Under 1 CFR Part 51 Pacific Aerospace Limited has issued Service Bulletin PACSB/XL/018, Issue 4, dated January 20, 2016. The service bulletin describes procedures for removing rivets (part number (P/N) MS20470 DD6) and installing bolts (P/ N NAS 6203–7X or NAS 6203–6X), washers (P/N AN960–10), and nuts (P/ N MS21044N3) in place of the rivets to restore airplane to full take-off weight of 7,500 pounds. The service bulletin 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 of this NPRM. E:\FR\FM\12APP1.SGM 12APP1 21490 Federal Register / Vol. 81, No. 70 / Tuesday, April 12, 2016 / Proposed Rules develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD will affect 9 products of U.S. registry. We also estimate that it would take about 32 work-hours per product to comply with the replacement requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $519 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $29,151, or $3,239 per product. AD 2006–13–05 affected 8 of the 9 U.S. registered airplanes reflected in the above cost information. This proposed AD would only increase the cost already required by AD 2006–13–05 by one additional airplane. The FAA has a report that the additional airplane is already in compliance, thus the proposed AD would impose no additional cost impact on U.S. operators. jstallworth on DSK7TPTVN1PROD with PROPOSALS 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, VerDate Sep<11>2014 15:12 Apr 11, 2016 Jkt 238001 (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. 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 39–14658 (71 FR 35509, June 21, 2006), and adding the following new AD: ■ Pacific Aerospace Limited: Docket No. FAA– 2016–5578; Directorate Identifier 2016– CE–005–AD. (a) Comments Due Date We must receive comments by May 27, 2016. (b) Affected ADs This AD replaces AD 2006–13–05, Amendment 39–14658 (71 FR 35509, June 21, 2006) (‘‘AD 2006–13–05’’). (c) Applicability This AD applies to the following Pacific Aerospace Limited Model 750XL airplanes (type certificate previously held by Pacific Aerospace Corporation Ltd.), that are certificated in any category.

This proposed AD was prompted by a design review, which found that the burst pressure of the flexible hose used to vent oxygen from the high-pressure relief valve of the oxygen cylinder overboard is lower than the opening pressure of the high-pressure relief valve. This pressure difference could cause the flexible hose to burst before it is able to vent excess oxygen overboard. This proposed AD would require replacement of flexible relief hoses for the crew oxygen bottles with new metal design relief hoses.

Airworthiness Directives; Pacific Aerospace Limited Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Pacific Aerospace Limited Model 750XL (type certificate 
previously held by Pacific Aerospace Corporation Ltd.) airplanes that 
would supersede AD 2006-13-05. 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 some critical rivets on the wing not being fully age-
hardened and being installed in specific locations where reduction in 
rivet strength reduces wing strength. We are issuing this proposed AD 
to require actions to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by May 27, 2016.

Discussion

    On June 12, 2006, we issued AD 2006-13-05, Amendment 39-14658 (71 
FR 35509, June 21, 2006) (``AD 2006-13-05''). That AD required actions 
intended to address an unsafe condition on certain Pacific Aerospace 
Corporation Ltd. Model 750XL airplanes and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country.
    Since we issued AD 2006-13-05, additional airplanes have been 
identified that need to be added to the applicability of the AD.
    The Civil Aviation Authority (CAA), which is the aviation authority 
for New Zealand, has issued AD No. DCA/750XL/7B, dated February 25, 
2016 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    DCA/750XL/7B revised to introduce PACSB/XL/018 issue 4, dated 20 
January 2016, which reduces the applicability to S/N 101 through to 
131 with no change to the requirements. Aircraft with S/N 132 
onwards have been modified in accordance with PACSB/XL/018 at 
manufacture, which is a terminating action for the requirements of 
this AD.

This proposed AD would require you to remove rivets that have not been 
fully age hardened and replace them with bolts, washers, and nuts in 
specific locations where reduction in rivet strength affects overall 
structural capability. The proposed AD would retain the airplane weight 
AFM limitations until the rivets are replaced with the bolts, washers, 
and nuts. You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2016-
5578.

Related Service Information Under 1 CFR Part 51

    Pacific Aerospace Limited has issued Service Bulletin PACSB/XL/018, 
Issue 4, dated January 20, 2016. The service bulletin describes 
procedures for removing rivets (part number (P/N) MS20470 DD6) and 
installing bolts (P/N NAS 6203-7X or NAS 6203-6X), washers (P/N AN960-
10), and nuts (P/N MS21044N3) in place of the rivets to restore 
airplane to full take-off weight of 7,500 pounds. The service bulletin 
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 of this NPRM.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or

develop on other products of the same type design.

Costs of Compliance

    We estimate that this proposed AD will affect 9 products of U.S. 
registry. We also estimate that it would take about 32 work-hours per 
product to comply with the replacement requirements of this proposed 
AD. The average labor rate is $85 per work-hour. Required parts would 
cost about $519 per product.
    Based on these figures, we estimate the cost of this proposed AD on 
U.S. operators to be $29,151, or $3,239 per product.
    AD 2006-13-05 affected 8 of the 9 U.S. registered airplanes 
reflected in the above cost information. This proposed AD would only 
increase the cost already required by AD 2006-13-05 by one additional 
airplane. The FAA has a report that the additional airplane is already 
in compliance, thus the proposed AD would impose no additional cost 
impact on U.S. operators.

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),
    (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.

List of Subjects in 14 CFR Part 39

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

0
1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-14658 (71 FR 
35509, June 21, 2006), and adding the following new AD:

Pacific Aerospace Limited: Docket No. FAA-2016-5578; Directorate 
Identifier 2016-CE-005-AD.

(a) Comments Due Date

    We must receive comments by May 27, 2016.

(b) Affected ADs

    This AD replaces AD 2006-13-05, Amendment 39-14658 (71 FR 35509, 
June 21, 2006) (``AD 2006-13-05'').

(c) Applicability

    This AD applies to the following Pacific Aerospace Limited Model 
750XL airplanes (type certificate previously held by Pacific 
Aerospace Corporation Ltd.), that are certificated in any category.
    (1) Airplanes previously affected by AD 2006-13-05: Serial 
numbers 101, 102, 104 through 120, and 125.
    (2) Airplanes new to this AD: Serial numbers 103, 121, 122, 123, 
124, and 126 to 131.

(d) Subject

    Air Transport Association of America (ATA) Code 57: Wings.

(e) Reason

    This 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 some critical 
rivets on the wing not being fully age-hardened and being installed 
in specific locations where reduction in rivet strength reduces wing 
strength. We are issuing this AD to add airplanes to the 
Applicability section, paragraph (c) of this AD, and to ensure wing 
ultimate load requirements are met. If wing ultimate load 
requirements are not met, wing failure could result with consequent 
loss of control.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Insert the following information into the Limitations 
section of the airplane flight manual (AFM) at the compliance time 
specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD. You may 
do this by inserting a copy of this AD into the Limitations section 
of the AFM: ``The maximum takeoff weight is reduced from 7,500 
pounds to 7,125 pounds.'' The owner/operator holding at least a 
private pilot certificate as authorized by section 43.7 of the 
Federal Aviation Regulations (14 CFR 43.7) may do the flight manual 
changes requirement of this AD. Make an entry in the aircraft 
records showing compliance with this portion of the AD following 
section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).
    (i) For airplanes previously affected by AD 2006-13-05: Before 
further flight after January 16, 2006 (the effective date retained 
from AD 2005-26-53, Amendment 39-14451 (71 FR 2453, January 17, 
2006), which was replaced by AD 2006-13-05).
    (ii) For airplanes new to this AD: Before further flight after 
the effective date of this AD.
    (2) Remove rivets, part number (P/N) MS20470 DD6, on the main 
spar web and replace with bolts, P/N NAS 6203-6X or -7X, as 
indicated for the position, assembled with washers, P/N AN960-10, 
and nut, P/N MS21044N3, at the compliance time specified in 
paragraphs (f)(2)(i) and (f)(2)(ii) of this AD.
    (i) For airplanes previously affected by AD 2006-13-05: Within 
the next 100 hours time-in-service (TIS) after July 31, 2006 (the 
effective date retained from AD 2006-13-05). Do the removal and 
replacement actions following Pacific Aerospace Corporation Ltd. 
Service Bulletin PACSB/XL/018, Issue 3, dated December 23, 2005, and 
amended January 16, 2006.
    (ii) For airplanes new to this AD: Within the next 100 hours TIS 
after the effective date of this AD or within the next 12 months 
after the effective date of this AD, whichever occurs first. Do the 
removal and replacement actions following Pacific Aerospace Limited 
Service Bulletin PACSB/XL/018, Issue 4, dated January 20, 2016.
    (3) For all affected airplanes: Before further flight after 
doing the action required in paragraph (f)(2) of this AD, remove the 
restrictive information from the Limitations section of the AFM that 
you were required to insert in paragraph (f)(1) of this AD. The 
owner/operator holding at least a private pilot certificate as 
authorized by section 43.7 of the Federal Aviation Regulations (14 
CFR 43.7) may do the flight manual changes requirement of this AD.
