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 British Aerospace Regional 
Aircraft Model HP 137 Jetstream MK1, Jetstream Series 200, and 
Jetstream Series 3101 airplanes. That NPRM was published in the Federal 
Register on February 17, 2017 (82 FR 10973), and proposed to supersede 
AD 2014-07-07,

[[Page 24466]]

Amendment 39-17821 (79 FR 23897; April 29, 2014) (``2014-07-07'').
    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:

    Prompted by occurrences of the main landing gear (MLG) yoke 
pintle housing cracking, the Civil Aviation Authority (CAA) UK 
issued AD 003-01-86 to require repetitive inspections to detect 
cracks in the yoke pintle housing on MLG fitted to Jetstream 3100 
aeroplanes in accordance with BAE Systems (Operations) Ltd Service 
Bulletin (SB) 32-A-JA851226, and, depending on findings, corrective 
action. After that AD was issued, an occurrence was reported of 
Jetstream 3100 MLG failure after landing. The subsequent 
investigation revealed stress corrosion cracking of the MLG yoke 
pintle housing to have caused this MLG failure. Furthermore, the 
investigation report recommended a review of the effectiveness of 
CAA UK AD 003-01-86 in finding cracks in the yoke pintle housing on 
MLG fitted to Jetstream 3100 aeroplanes.
    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 detected and 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 provide protection of the affected area of the MLG assembly 
spigot housing, BAE Systems (Operations) Ltd issued SB 32-JM7862 to 
provide instructions for installation of a protective washer, fitted 
at the forward spigot on both left hand and right hand MLG. 
Consequently, BAE Systems (Operations) Ltd issued SB 32-A-JA851226 
Revision 05 to provide additional accomplishment instructions for a 
Non-destructive testing (NDT) inspection of MLG equipped with the 
protective washer installed in accordance with BAE Systems 
(Operations) Ltd SB 32-JM7862.
    Consequently, EASA issued AD 2013-0208, retaining the 
requirements of CAA UK AD 003-01-86, which was superseded, and 
required implementation of revised inspection requirements, and, 
depending on findings, accomplishment of applicable corrective 
action(s). That AD also introduced an optional modification, which 
constituted terminating action for the inspections required by that 
AD.
    Since that AD was issued, BAE Systems (Operations) Ltd has 
determined that the existing inspection procedure may not be 
effective in identifying stress corrosion cracking in the pintle 
housing. Consequently BAE Systems (Operations) Ltd has published an 
improved inspection procedure in SB 32-A-JA851226 Revision 07. This 
improved inspection procedure has the ability to detect smaller 
corrosion pits and cracks that are proximate in size to those that 
will initiate stress corrosion.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0208, which is superseded, and requires 
MLG inspections in accordance with the improved procedure.

The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/document?D=FAA-2017-0053-0002.

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 British Aerospace Jetstream Series 3100 & 3200 Service 
Bulletin 32-A-JA851226, Revision 7, dated May 25, 2015. The service 
information describes procedures for nondestructive testing (NDT) and 
visual inspections of the main landing gear spigot housing for cracks 
and repair if necessary. 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 final rule.

Costs of Compliance

    We estimate that this AD will affect 26 products of U.S. registry. 
We also estimate that it would take about 14 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 this cost of the AD on U.S. 
operators to be $30,940, or $1,190 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2 work-hours and require parts costing $5,000, for a cost of 
$5,170 per product. We have no way of determining the number of 
products that may need these actions.

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.

 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 39-17821 (82 FR 
23897; April 29, 2014), and adding the following new AD:

2017-10-14 British Aerospace Regional Aircraft: Amendment 39-18888; 
Docket No. FAA-2017-0053; Directorate Identifier 2016-CE-037-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective July 5, 
2017.

(b) Affected ADs

    This AD supersedes AD 2014-07-07, Amendment 39-17821 (79 FR 
23897, April 29, 2014) (``2014-07-07'').

(c) Applicability

    This AD applies to British Aerospace (Operations) Limited Model 
HP.137 Jetstream Mk.1, Jetstream Series 200, and Jetstream Series 
3101 airplanes, all serial numbers, certificated in any category.

Gear.

(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 cracking of the 
forward main landing gear yoke pintle resulting from corrosion pits 
which can cause stress corrosion cracking resulting in loss of 
control during take-off or landing. We are issuing this AD to revise 
the inspection procedure to detect smaller corrosion pits and cracks 
that could initiate stress corrosion cracking.

(f) Actions and Compliance

    Unless already done, do the following actions specified in 
paragraphs (f)(1) through (11) of this AD:
    (1) For all airplanes: Before or at the next inspection that 
would have been required by AD 2014-07-07 or within the next 30 days 
after July 5, 2017 (the effective date of this AD), whichever occurs 
later, and repetitively thereafter at intervals not to exceed 12 
months or 1,200 main landing gear (MLG) flight cycles (FC), 
whichever occurs first, do a nondestructive testing (NDT) inspection 
of each MLG assembly cylinder attachment spigot housing following 
the accomplishment instructions in Heroux Devtek Service Bulletin 
(SB) 32-19, Revision 7, dated March 16, 2015, as specified in the 
accomplishment instructions in paragraph 2.B. Part A of British

further flight, take all necessary corrective actions following the 
instructions in British Aerospace Jetstream Series 3100 & 3200 SB 
32-A-JA851226, Revision 7, dated May 25, 2015.
    (7) For all airplanes: Doing all necessary corrective actions 
required in paragraphs (f)(5) or (6) of this AD does not constitute 
terminating action for the inspections required by this AD.
    (8) For all airplanes: Modification of each MLG cylinder 
following BAE Systems (Operations) Ltd. SB 32-JA880340 original 
issue, dated January 6, 1989, constitutes terminating action for the 
inspections required by this AD for that MLG.
    (9) For all airplanes: The compliance times in paragraphs 
(f)(1), (2), (3), and (4) of this AD are presented in flight cycles 
(landings). If the total flight cycles have not been kept, multiply 
the total number of airplane hours time-in-service (TIS) by 0.75 to 
calculate the cycles. For the purposes of this AD:
    (i) 100 hours TIS x .75 = 75 cycles; and
    (ii) 1,000 hours TIS x .75 = 750 cycles.

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

    (1) This AD allows credit for the initial inspection required in 
paragraph (f)(1) of this AD if done before June 3, 2014 (the 
effective date retained from AD 2014-07-07) following British 
Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-A-
JA851226, Revision 5, dated April 30, 2013.
    (2) This AD allows credit for the initial inspection required in 
paragraph (f)(4) of this AD if done before June 3, 2014 (the
