SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. That NPRM was published in the Federal Register on December 3, 2013 (78 FR 72598). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: An occurrence of Jetstream 3100 main landing gear (MLG) failure after landing was reported. The subsequent investigation revealed stress corrosion cracking of the MLG yoke pintle housing as a root cause of the MLG failure. Degradation of the surface protection by abrasion can occur when the forward face of the yoke pintle rotates against the pintle bearing, which introduces corrosion pits and, consequently, stress corrosion cracking. This condition, if not corrected, could lead to structural failure of the MLG possibly resulting in loss of control of the aeroplane during take-off or landing runs. To address this potential unsafe condition, BAE Systems (Operations) Ltd issued Service Bulletin (SB) 32–JM7862 to provide instruction for installation of a protective washer fitted at the forward spigot on both, left hand (LH) and right hand (RH), MLG. For the reasons described above, this AD requires installation of a washer to protect the MLG at the forward face of the yoke pintle. The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/ #!documentDetail;D=FAA-2013-10120002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 72598, December 3, 2013) 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 (78 FR 72598, December 3, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 72598, December 3, 2013).

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 Rockwell Collins TPR– 720 and TPR–900 Mode select (S) transponders that are installed on airplanes. The NPRM published in the Federal Register on November 19, 2013 (78 FR 69318). The NPRM proposed to require testing and calibration of the alignment of the TPR–720 and TPR–900 Mode S transponders. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. Request FAA Review Impact on AD 92– 11–09 (57 FR 20744, May 15, 1992) Konstantinos Sideris of Airbus commented that AD 92–11–09 (57 FR 20744, May 15, 1992) required converting part number (P/N) 622– 7878–020 into P/N 622–7878–301. The PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 17397 commenter stated that the proposed AD would affect both of those P/Ns, and he requested the FAA review the impact of the proposed AD on AD 92–11–09 and consider cancelling AD 92–11–09. After review, we disagree with cancelling AD 92–11–09 (57 FR 20744, May 15, 1992). This AD requires a different task than that required in AD 92–11–09 and assures timely test and calibration for all affected P/Ns, including those affected and referenced in AD 92–11–09. We did not change the final rule AD action based on this comment. Request FAA Add and Delete Specific Model Airplanes from Applicability The Boeing Company requested we add Models 737 classics, 737NG, 757, and 767 airplanes to the Applicability and exclude the Model 747–8. We agree that this AD may apply to Models 737, 757, and 767 airplanes; however, paragraph (c), Applicability, of this AD is not intended as all-inclusive. Paragraph (c) of this AD states, ‘‘. . . transponders that are installed on but not limited to the airplanes . . .’’ and gives a partial listing of airplanes known to have the affected transponders installed. In our discussions with Rockwell Collins, they discussed that the subject transponders may be installed by supplemental type certificate on models other than the models that are known to have the affected transponders installed. We added language to paragraph (c), Applicability, to clarify that the listing of airplanes is not all-inclusive. Request FAA Change the Cost of Compliance Estimate The Boeing Company requested we adjust the total estimated cost of compliance to account for the added airplane models the commenter requested we add. We disagree with this comment. We based the estimated cost of compliance on the number of transponder units produced by Rockwell Collins, not the estimated number of airplanes that may have the transponders installed. We did not change the final rule AD action based on this comment. Request FAA Change the Language of the Required Action Craig Amadeo of Delta Airlines requested we change the language in the AD to clarify that the operators do not have to return the transponders to Rockwell Collins for the testing and calibration. Delta has full capability to test and align the receiver of the affected transponders. The commenter also requested we add more specific E:\FR\FM\28MRR1.SGM 28MRR1

Airworthiness Directives; British Aerospace Regional Aircraft 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for British 
Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 
3201 airplanes. This AD results from 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 stress corrosion cracking of the 
main landing gear yoke pintle housing on a Jetstream series 3100 
airplane. We are issuing this AD to require actions to address the 
unsafe condition on these products.

DATES: This AD is effective May 2, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of May 2, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to British Aerospace Regional 
Aircraft Jetstream Series 3101 and Jetstream Model 3201 airplanes. That 
NPRM was published in the Federal Register on December 3, 2013 (78 FR 
72598). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    An occurrence of Jetstream 3100 main landing gear (MLG) failure 
after landing was reported. The subsequent investigation revealed 
stress corrosion cracking of the MLG yoke pintle housing as a root 
cause of the MLG failure. Degradation of the surface protection by 
abrasion can occur when the forward face of the yoke pintle rotates 
against the pintle bearing, which introduces corrosion pits and, 
consequently, stress corrosion cracking.
    This condition, if not corrected, could lead to structural 
failure of the MLG possibly resulting in loss of control of the 
aeroplane during take-off or landing runs.
    To address this potential unsafe condition, BAE Systems 
(Operations) Ltd issued Service Bulletin (SB) 32-JM7862 to provide 
instruction for installation of a protective washer fitted at the 
forward spigot on both, left hand (LH) and right hand (RH), MLG.

For the reasons described above, this AD requires installation of a 
washer to protect the MLG at the forward face of the yoke pintle. The 
MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-1012-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 72598, December 3, 
2013) 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 (78 FR 72598, December 3, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 72598, December 3, 2013).

Costs of Compliance

    We estimate that this AD will affect 66 products of U.S. registry. 
We also estimate that it would take about 15 work-hours 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 $84,150, or $1,275 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
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 AD:

2014-06-03 British Aerospace Regional Aircraft: Amendment 39-17807; 
Docket No. FAA-2013-1012; Directorate Identifier 2013-CE-037-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective May 2, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to British Aerospace Regional Aircraft Jetstream 
Series 3101 and Jetstream Model 3201 airplanes, all serial numbers, 
certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 32: Landing 
Gear.

(e) Reason

    This AD was prompted by 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 stress corrosion 
cracking of the main landing gear yoke pintle housing. We are 
issuing this AD to prevent abrasion and subsequent corrosion from 
building on the main landing gear (MLG) yoke pintle housing. This 
condition if not corrected could cause structural failure of the MLG 
resulting in loss of control during take-off or landing.

(f) Actions and Compliance

    Unless already done, do the following actions as applicable in 
paragraphs (f)(1) and (f)(2) of this AD:
    (1) At the next scheduled MLG removal after May 2, 2014 (the 
effective date of this AD), modify the left hand (LH) and right hand 
(RH) MLG installation at the forward spigot following the 
accomplishment instructions of British Aerospace Jetstream Series 
3100 & 3200 Service Bulletin 32-JM7862, Revision 1, dated May 7, 
2013.
    (2) As of May 2, 2014 (the effective date of this AD), do not 
install any LH or RH MLG on Jetstream Series 3101 airplanes and 
Jetstream Model 3201 airplanes unless it is found to be in 
compliance with the requirements of paragraph (f)(1) of this AD.

(g) Credit for Actions Done in Accordance With Previous Service 
Information

    This AD allows credit for the requirements of paragraph (f)(1) 
of this AD if already done before May 2, 2014 (the effective date of 
this AD), following British Aerospace Jetstream Series 3100 & 3200 
Service Bulletin SB 32-JM7862, original issue, dated April 8, 2013.

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
