SUPPLEMENTARY INFORMATION: PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 1179 Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to B–N Group Ltd. Models BN–2, BN–2A, BN–2A–2, BN–2A–3, BN–2A–6, BN–2A–8, BN–2A–9, BN–2A–20, BN– 2A–21, BN–2A–26, BN–2A–27, BN–2B– 20, BN–2B–21, BN–2B–26, BN–2B–27, BN–2T–4R, BN–2T, BN2A MK. III, BN2A MK. III–2, and BN2A MK. III–3 (all models on Type Certificate Data Sheets A17EU and A29EU) airplanes. That NPRM was published in the Federal Register on September 23, 2016 (81 FR 65581), and proposed to supersede AD 2016–06–01, Amendment 39–18432 (81 FR 13717; March 15, 2016). Since we issued AD 2016–06–01, errors were discovered in the model applicability after issuance. This AD adds Models BN–2T and BN–2T–4R, removes nonexistent Model BN2B, and removes duplicate listings of BN2A and BN2A MK.III. The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states that: In 2005, occurrences were reported of finding cracks in the inner shell of certain pitot/static pressure heads, Part Number (P/ N) DU130–24. This condition, if not detected and corrected, could lead to incorrect readings on the pressure instrumentation, e.g. altimeters, vertical speed indicators (rate-of-climb) and airspeed indicators, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, B–N Group issued Service Bulletin (SB) 310 to provide inspection and test instructions. Consequently, CAA UK issued AD G–2005– 0034 (EASA approval 2005–6447) to require repetitive inspections and leak tests and, depending on findings, accomplishment of applicable corrective action(s). Subsequently, B–N Group published SB 310 issue 2, prompting EASA to issue AD 2006–0143 making reference to SB 310 at issue 2, while the publication of BNA SB 310 issue 3 prompted EASA AD 2006–0143R1, introducing BNA modification (mod) NB–M– 1728 (new pitot/static pressure head not affected by the AD requirements) as optional terminating action for the repetitive inspections and leak tests. Since that AD was issued, operators have reported a number of premature failures of the affected P/N DU130–24 pitot-static probes. Prompted by these reports, BNA issued SB 310 issue 4 to reduce the interval for the inspections and leak tests. The MCAI can be found in the AD docket on the Internet at: https:// E:\FR\FM\05JAR1.SGM 05JAR1 1180 Federal Register / Vol. 82, No. 3 / Thursday, January 5, 2017 / Rules and Regulations www.regulations.gov/ document?D=FAA-2016-9160-0002. 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 relevant data and determined that air safety and the public interest require adopting the AD as proposed except for 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. Related Service Information We reviewed B–N Group Ltd. BrittenNorman Service Bulletin Number SB 310, Issue 4, dated September 25, 2015. The service information describes procedures for inspections, and if necessary, replacement of the pitot/ static pressure head. 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 of the AD. Costs of Compliance We estimate that this AD will affect 93 products of U.S. registry. We also estimate that it would take about 1 work-hour 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 $7,905, or $85 per product. In addition, we estimate that any necessary follow-on actions would take about 2 work-hours and require parts costing $10,000, for a cost of $10,170 per product. We have no way of determining the number of products that may need these actions. The cost impact of this AD is the same as that presented in AD 2016–06–01. asabaliauskas on DSK3SPTVN1PROD with RULES 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, VerDate Sep<11>2014 18:22 Jan 04, 2017 Jkt 241001 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 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 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.

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 B-N Group Ltd. Models BN-2, 
BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21, 
BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN-2T-4R, 
BN-2T, BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 (all models on 
Type Certificate Data Sheets A17EU and A29EU) airplanes. That NPRM was 
published in the Federal Register on September 23, 2016 (81 FR 65581), 
and proposed to supersede AD 2016-06-01, Amendment 39-18432 (81 FR 
13717; March 15, 2016).
    Since we issued AD 2016-06-01, errors were discovered in the model 
applicability after issuance. This AD adds Models BN-2T and BN-2T-4R, 
removes nonexistent Model BN2B, and removes duplicate listings of BN2A 
and BN2A MK.III.
    The NPRM proposed to correct an unsafe condition for the specified 
products and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country. The MCAI states that:

    In 2005, occurrences were reported of finding cracks in the 
inner shell of certain pitot/static pressure heads, Part Number (P/
N) DU130-24.
    This condition, if not detected and corrected, could lead to 
incorrect readings on the pressure instrumentation, e.g. altimeters, 
vertical speed indicators (rate-of-climb) and airspeed indicators, 
possibly resulting in reduced control of the aeroplane.
    To address this potential unsafe condition, B-N Group issued 
Service Bulletin (SB) 310 to provide inspection and test 
instructions. Consequently, CAA UK issued AD G-2005-0034 (EASA 
approval 2005-6447) to require repetitive inspections and leak tests 
and, depending on findings, accomplishment of applicable corrective 
action(s).
    Subsequently, B-N Group published SB 310 issue 2, prompting EASA 
to issue AD 2006-0143 making reference to SB 310 at issue 2, while 
the publication of BNA SB 310 issue 3 prompted EASA AD 2006-0143R1, 
introducing BNA modification (mod) NB-M-1728 (new pitot/static 
pressure head not affected by the AD requirements) as optional 
terminating action for the repetitive inspections and leak tests.
    Since that AD was issued, operators have reported a number of 
premature failures of the affected P/N DU130-24 pitot-static probes.
    Prompted by these reports, BNA issued SB 310 issue 4 to reduce 
the interval for the inspections and leak tests.

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 relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
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.

Related Service Information

    We reviewed B-N Group Ltd. Britten-Norman Service Bulletin Number 
SB 310, Issue 4, dated September 25, 2015. The service information 
describes procedures for inspections, and if necessary, replacement of 
the pitot/static pressure head. 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 of the AD.

Costs of Compliance

    We estimate that this AD will affect 93 products of U.S. registry. 
We also estimate that it would take about 1 work-hour 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 $7,905, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2 work-hours and require parts costing $10,000, for a cost 
of $10,170 per product. We have no way of determining the number of 
products that may need these actions.
    The cost impact of this AD is the same as that presented in AD 
2016-06-01.

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 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 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, 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

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]

2. The FAA amends Sec.  39.13 by removing Amendment 39-18432 (81 FR 
13717; March 15, 2016) and adding the following new AD:

2016-26-09 B-N Group Ltd.: Amendment 39-18767; Docket No. FAA-2016-
9160; Directorate Identifier 2016-CE-022-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective February 9, 
2017.

(b) Affected ADs

    This AD supersedes AD 2016-06-01, Amendment 39-18432 (81 FR 
13717; March 15, 2016) (``AD 2016-06-01'').

(c) Applicability

    This AD applies to B-N Group Ltd. Models BN-2, BN-2A, BN-2A-2, 
BN-2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21, BN-2A-26, 
BN-2A-27, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN-2T-4R, BN-2T, 
BN2A MK. III, BN2A MK. III-2, and BN2A MK. III-3 (all models on Type 
Certificate Data Sheets A17EU and A29EU) airplanes, all serial 
numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 34: Navigation.

(e) Reason

    This AD was prompted by 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 cracks in the 
inner shell of certain pitot/static pressure heads, which could 
cause incorrect readings on the pressure instrumentation, possibly 
resulting in reduced control of the airplane. We are issuing this AD 
to change the model applicability due to errors found in AD 2016-06-
01.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) through (5) of this AD:
    (1) For all airplanes that are equipped with pitot/static 
pressure head part number (P/N) DU130-24, except Models BN-2T and 
BN-2T-4R: Within 50 hours time-in-service (TIS) after April 19, 2016 
(the effective date retained from AD 2016-06-01) and repetitively 
thereafter at intervals not to exceed 50 hours TIS, inspect the 
pitot/static pressure head for cracks and/or separation and perform 
a leak test following the procedures in the action section of 
Britten-Norman Service Bulletin SB 310, Issue 4, dated September 25,
