ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. This AD was prompted by reports of cracking of the main fitting of the nose landing gear (NLG) and a determination that a new safe-life limitation for affected NLG main fittings has not been mandated. This AD requires replacing affected NLG main fittings that have exceeded the safe-life limitation with a new or serviceable fitting. We are issuing this AD to prevent collapse of the NLG, which if not corrected, could lead to degradation of direction control on the ground or an un-commanded turn to the left, and a consequent loss of control of the airplane on the ground, possibly resulting in damage to the airplane and injury to occupants.

SUPPLEMENTARY INFORMATION: Prompted by these findings, BAE Systems (Operations) Ltd issued Inspection Service Bulletin (ISB) 32–186 (hereafter referred to as the ISB) to introduce a new safe life of 16,000 flight cycles (FC) for certain NLG main fittings, having a Part Number (P/N) as identified in Paragraph 1A, tables 1, 2 and 3 of the ISB. To correct this unsafe condition, EASA issued [EASA] AD 2012–0191 to require implementation of the new safe-life limitation for the affected NLG main fittings and replacement of fittings that have already exceeded the new limit. Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. The NPRM published in the Federal Register on November 12, 2015 (80 FR 69903) (‘‘the NPRM’’). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2012–0191R1, dated November 6, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. The MCAI states: We reviewed the available data and determined that air safety and the public interest require adopting this 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. Several occurrences of the aeroplane‘s Nose Landing Gear (NLG) Main Fitting cracking have been reported. Subsequently in different cases, NLG Main Fitting crack lead to collapsed NLG, locked NLG steering and an aeroplane‘s un-commanded steering to the left. Cracks in the NLG Bell Housing are not detectable with the NLG fitted to the aeroplane and are difficult to detect during overhaul without substantial disassembly of the gear. This condition, if not corrected, could lead to degradation of directional control on the ground or an un-commanded turn to the left and a consequent loss of control of the aeroplane on the ground, possibly resulting in damage to the aeroplane and injury to occupants.

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 Related Service Information Under 1 CFR Part 51 BAE Systems (Operations) Limited has issued Inspection Service Bulletin ISB.32–186, dated April 12, 2012. This service information describes procedures for reviewing airplane records to determine the part number for the NLG main fittings, and determining the compliance times for replacing the NLG main fittings, and replacing the fitting with a new or serviceable fitting. 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 4 airplanes of U.S. registry. We also estimate that it takes about 36 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost $81,000 per product. Based on these figures, we E:\FR\FM\31MRR1.SGM 31MRR1 18470 Federal Register / Vol. 81, No. 62 / Thursday, March 31, 2016 / Rules and Regulations estimate the cost of this AD on U.S. operators to be $336,240, or $84,060 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 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. jstallworth on DSK7TPTVN1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

ACTION: Final rule. jstallworth on DSK7TPTVN1PROD with RULES AGENCY: This action removes a provision in part 71 that excludes from Class A airspace, that portion of U.S. domestic airspace that overlies the Santa Barbara and Farallon Islands and the airspace south of latitude 25°04′00″ North (overlying and in the vicinity of the Florida Keys). The effect of this SUMMARY: 15:13 Mar 30, 2016 Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it removes from 14 CFR 71.33(a) a provision that excludes the airspace in the vicinity of the Santa Barbara and Farallon Islands and the Florida Keys from U.S. Class A airspace in order to maintain the safe and efficient flow of air traffic. Background [Docket No. FAA–2016–5391; Airspace Docket No. 16–AWA–3] VerDate Sep<11>2014 provision is that the airspace from 18,000 feet MSL up to and including Flight Level (FL) 600 (within the excluded areas) is classified as Class G (uncontrolled) airspace which limits the flexibility for air traffic control operations.

SUPPLEMENTARY INFORMATION: Jkt 238001 Positive Control Areas In 1958, the Civil Aeronautics Board delegated to the Administrator the authority to designate positive control route segments in any portion of the airspace between 17,000 to 35,000 feet, within which certain operational requirements would be applicable. That same year the Administrator designated in 14 CFR part 601 specific airways as positive control airspace, noting that ‘‘with experience and the acquisition of more and better equipment, the positive control area will undoubtedly, from time to time, be expanded.’’ 23 FR 3917 (June 5, 1958). In 1962, the FAA redesignated part 601 as part 71. 27 FR 10353 (Oct. 24, PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 18471 1962). Section 71.15 addressed positive control areas, and § 71.193 (published separately) contained those areas designated as positive control areas. Over several years, the airspace designated as positive control areas continued to expand as anticipated with the FAA’s increased capability to control air traffic. In 1965, the FAA established an expansive area of positive control airspace designated the ‘‘continental positive control area.’’ 30 FR 1836 (February 10, 1965). The FAA excluded from that positive control area the airspace over Santa Barbara Island and the Farallon Islands, and the airspace south of the latitude 25°04′00″ North. Class A Airspace In 1991, the FAA issued a final rule reclassifying ‘‘positive control areas’’ as Class A airspace.1 56 FR 65638, 65639 (Dec. 17, 1991).2 In that final rule, new § 71.33 defined Class A airspace and continued to exclude from Class A airspace that airspace over Santa Barbara Island, the Farallon Islands, and south of latitude 25°04′00″ North that was originally established in 1965. Unless otherwise specified, Class A airspace in the United States consists of that airspace from 18,000 feet MSL up to and including flight level (FL) 600. Unless otherwise authorized, all persons must operate their aircraft under instrument flight rules in airspace designated as Class A and comply with the applicable requirements of 14 CFR part 91. ‘‘Class A airspace’’ includes, in part, ‘‘that airspace overlying the waters within 12 nautical miles of the coast of the 48 contiguous States, from 18,000 feet MSL to and including FL600 excluding the states of Alaska and Hawaii, Santa Barbara Island, Farallon Island, and the airspace south of latitude 25°04′00″ North.’’ The airspace excluded from Class A airspace over the Santa Barbara and Farallon Islands and the airspace south of 25°04′00″ North renders those portions of U.S. domestic airspace (i.e., within 12 nautical miles (NM) of the baseline of the United States) as Class G (uncontrolled) airspace, which limits the provision of air traffic control services in those areas. As these excluded areas lie within the 12 NM territorial limits of the United States, the airspace would ordinarily be classified as Class A airspace. When the exclusions were implemented decades ago, air traffic control services in the 1 The reclassification adopted the International Civil Aviation Organization (ICAO) letter classifications.

Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all BAE 
Systems (Operations) Limited Model BAe 146 series airplanes and Model 
Avro 146-RJ series airplanes. This AD was prompted by reports of 
cracking of the main fitting of the nose landing gear (NLG) and a 
determination that a new safe-life limitation for affected NLG main 
fittings has not been mandated. This AD requires replacing affected NLG 
main fittings that have exceeded the safe-life limitation with a new or 
serviceable fitting. We are issuing this AD to prevent collapse of the 
NLG, which if not corrected, could lead to degradation of direction 
control on the ground or an un-commanded turn to the left, and a 
consequent loss of control of the airplane on the ground, possibly 
resulting in damage to the airplane and injury to occupants.

DATES: This AD becomes effective May 5, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 5, 2016.

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 all BAE Systems 
(Operations) Limited Model BAe 146 series airplanes and Model Avro 146-
RJ series airplanes. The NPRM published in the Federal Register on 
November 12, 2015 (80 FR 69903) (``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2012-0191R1, dated November 6, 2012 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all BAE Systems 
(Operations) Limited Model BAe 146 series airplanes and Model Avro 146-
RJ series airplanes. The MCAI states:

    Several occurrences of the aeroplane`s Nose Landing Gear (NLG) 
Main Fitting cracking have been reported. Subsequently in different 
cases, NLG Main Fitting crack lead to collapsed NLG, locked NLG 
steering and an aeroplane`s un-commanded steering to the left.
    Cracks in the NLG Bell Housing are not detectable with the NLG 
fitted to the aeroplane and are difficult to detect during overhaul 
without substantial disassembly of the gear.
    This condition, if not corrected, could lead to degradation of 
directional control on the ground or an un-commanded turn to the 
left and a consequent loss of control of the aeroplane on the 
ground, possibly resulting in damage to the aeroplane and injury to 
occupants.
    Prompted by these findings, BAE Systems (Operations) Ltd issued 
Inspection Service Bulletin (ISB) 32-186 (hereafter referred to as 
the ISB) to introduce a new safe life of 16,000 flight cycles (FC) 
for certain NLG main fittings, having a Part Number (P/N) as 
identified in Paragraph 1A, tables 1, 2 and 3 of the ISB.
    To correct this unsafe condition, EASA issued [EASA] AD 2012-
0191 to require implementation of the new safe-life limitation for 
the affected NLG main fittings and replacement of fittings that have 
already exceeded the new limit.

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 available data and determined that air safety and 
the public interest require adopting this 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 Under 1 CFR Part 51

    BAE Systems (Operations) Limited has issued Inspection Service 
Bulletin ISB.32-186, dated April 12, 2012. This service information 
describes procedures for reviewing airplane records to determine the 
part number for the NLG main fittings, and determining the compliance 
times for replacing the NLG main fittings, and replacing the fitting 
with a new or serviceable fitting. 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 4 airplanes of U.S. registry.
    We also estimate that it takes about 36 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost $81,000 per product. 
Based on these figures, we

[[Page 18470]]

estimate the cost of this AD on U.S. operators to be $336,240, or 
$84,060 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 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.

reference, 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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-07-06 BAE Systems (Operations) Limited: Amendment 39-18451. 
Docket No. FAA-2015-4212; Directorate Identifier 2015-NM-010-AD.

(a) Effective Date

    This AD becomes effective May 5, 2016.

(b) Affected ADs

    None.

(c) Applicability

    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 
models, all serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks.

(e) Reason

    This AD was prompted by reports of cracking of the main fitting 
of the nose landing gear (NLG) and a determination that a new safe-
life limitation for affected NLG main fittings has not been 
mandated. We are issuing this AD to prevent collapse of the NLG, 
which if not corrected, could lead to degradation of direction 
control on the ground or an uncommanded turn to the left, and a 
consequent loss of control of the airplane on the ground, possibly 
resulting in damage to the airplane and injury to occupants.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Replacement of NLG Main Fitting

    At the applicable compliance time specified in paragraphs (g)(1) 
through (g)(4) of this AD: Replace each affected NLG main fitting, 
having a part number (P/N) as identified in paragraph 1.A, tables 
1., 2., and 3. of BAE Systems (Operations) Limited Inspection 
Service Bulletin ISB.32-186, dated April 12, 2012, in accordance 
with the Accomplishment Instructions of that BAE Systems 
(Operations) Limited Inspection Service Bulletin ISB.32-186, dated 
April 12, 2012. Thereafter, before the accumulation of 16,000 flight 
cycles on any affected NLG main fitting having a part number as 
identified in paragraph 1.A, tables 1., 2., and 3. of BAE Systems 
(Operations) Limited Inspection Service Bulletin ISB.32-186, dated 
April 12, 2012, replace each affected NLG main fitting, in 
accordance with the Accomplishment Instructions of that BAE Systems 
(Operations) Limited Inspection Service Bulletin ISB.32-186, dated 
April 12, 2012.
    (1) For NLG main fittings that have accumulated 29,000 flight 
cycles or more since first installation on an airplane: Within 12 
months after the effective date of this AD.
    (2) For NLG main fittings that have accumulated 20,000 flight 
cycles or more but less than 29,000 flight cycles since first 
installation on an airplane: Within 24 months after the effective 
date of this AD.
    (3) For NLG main fittings that have accumulated 16,000 flight 
cycles or more but less than 20,000 flight cycles since first 
installation on an airplane: Within 36 months after the effective 
date of this AD.
    (4) For NLG main fittings that have accumulated less than 16,000 
flight cycles since first installation on an airplane: Before 
accumulating 16,000 flight cycles since first installation on an 
airplane, or within 36 months after the effective date of this AD, 
whichever occurs later.

(h) Parts Installation Limitation

    As of the effective date of this AD, no person may install an 
NLG main fitting having a part number identified in paragraph 1.A., 
tables 1., 2., and 3., of BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.32-186, dated April 12, 2012, unless 
that fitting is in compliance with the requirements of this AD.
