SUMMARY: We are adopting a new airworthiness directive (AD) for British 
Aerospace Regional Aircraft Model HP.137 Jetstream Mk.1, Jetstream 
Series 200 and 3101, and Jetstream Model 3201 airplanes that would 
supersede AD 97-10-05. 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 cracks in 
the main landing gear (MLG) fitting at the pintle to cylinder 
interface, which could cause failure of the MLG during takeoff and 
landing. We are issuing this AD to require actions to address the 
unsafe condition on these products.

DATES: This AD is effective August 31, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 31, 
2017.

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 Mk.1, Jetstream Series 200 and 3101, 
and Jetstream Model 3201 airplanes. The NPRM was published in the 
Federal Register on April 28, 2017 (82 FR 19646), and proposed to 
supersede AD 97-10-05, Amendment 39-10017 (62 FR 28318; May 23, 1997). 
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:

    Cracks were found during early fatigue testing and in service on 
the main landing gear (MLG) main fitting at the pintle to cylinder 
interface.
    This condition, if not detected and corrected, could lead to 
structural failure of

[[Page 34847]]

the MLG, possibly resulting in loss of control of the aeroplane 
during take-off or landing runs.
    To address this unsafe condition, BAE Systems (Operations) Ltd 
published several Service Bulletins (SB) which, in 1996, were 
consolidated into a single SB 32-JA960142 to provide instructions 
for inspection. CAA UK issued AD 005-03-96 accordingly to require 
repetitive inspections of the MLG.
    Recently, a crack was found which was below the critical crack 
length, but unusually large compared to other similar cracks 
previously found in service. Further investigation into the subject 
determined that the existing inspection interval remains valid, but 
also showed that the assumed detectable defect size of 1.27 mm (0.05 
in) crack cannot be guaranteed using the current accomplishment 
instructions for high frequency eddy current (HFEC) or fluorescent 
dye penetrant (FDP) inspection.
    Consequently, BAE Systems (Operations) Ltd issued SB 32-JA960142 
Revision 04, which provides improved procedures for HFEC and FDP 
inspection to ensure the detection of cracks of 1.27 mm (0.05 in).
    For the reason described above, the [EASA] AD retains the 
requirements of CAA UK AD 005-03-96, which is superseded, and 
requires accomplishment of repetitive inspections in accordance with 
the improved procedures.

    The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/document?D=FAA-2017-0395-0002.

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 Under 1 CFR Part 51

    We reviewed British Aerospace Jetstream Series 3100 and 3200 
Service Bulletin 32-JA960142, Revision No. 4, October 21, 2016, which 
describes procedures for doing non-destructive testing for cracks in 
the MLG and corrective actions if cracks found exceed a certain crack 
length. (The appendix to the service bulletin specifically describes 
fluorescent liquid penetrant testing.) We also reviewed Heroux Devtek 
Service Bulletin 32-56, Revision 4, dated August 16, 2016, which 
describes procedures for doing a non-destructive testing eddy current 
inspection for cracks in the MLG. 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 this document.

Costs of Compliance

    We estimate that this AD will affect 26 products of U.S. registry. 
We also estimate that it would take about 6 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 $13,260, or $510 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour and require parts costing $5,000, for a cost of 
$5,085 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.

the following new AD:

2017-15-06 British Aerospace Regional Aircraft: Amendment 39-18966; 
Docket No. FAA-2017-0395; Directorate Identifier 2017-CE-011-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective August 31, 
2017.

(b) Affected ADs

    This AD replaces AD 97-10-05; Amendment 39-10017 (62 FR 28318; 
May 23, 1997) (``AD 97-10-05'').

(c) Applicability

    This AD applies to British Aerospace Regional Aircraft Model 
HP.137 Jetstream Mk.1, Jetstream Series 200 and 3101, and

[[Page 34848]]

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 cracks in the 
main landing gear (MLG) fitting at the pintle to cylinder interface, 
which could cause failure of the MLG during takeoff and landing. We 
are issuing this AD to detect and correct cracks in the main landing 
gear (MLG), which could lead to structural failure of the MLG and 
could result in loss of control during takeoffs and landings.

(f) Actions and Compliance

    Unless already done, do the following actions listed in 
paragraphs (f)(1) through (3) of this AD:
    (1) Within the compliance times listed in paragraph (f)(1)(i) or 
(ii) of this AD, as applicable, inspect the MLG for cracks following 
Appendix 1 of British Aerospace Jetstream Series 3100 and 3200 
Service Bulletin 32-JA960142, Revision No. 4, October 21, 2016; or 
Heroux Devtek Service Bulletin 32-56, Revision 4, dated August 16, 
2016, as specified in British Aerospace Jetstream Series 3100 and 
3200 Service Bulletin 32-JA960142, Revision No. 4, October 21, 2016.
    (i) For airplanes that have been inspected following AD 97-10-
05: Do the initial inspection within 1,200 flight cycles (FC) after 
the last inspection required by AD 97-10-05 and repetitively 
thereafter at intervals not to exceed 1,200 FC.
    (ii) For airplanes that have not been inspected following AD 97-
10-05: Do the initial inspection within 8,000 FC after installation 
of the MLG or within the next 100 FC after August 31, 2017 (the 
effective date of this AD), whichever occurs later, and repetitively 
thereafter at intervals not to exceed 1,200 FC.
    (2) If any cracks are found during any of the inspections 
required in paragraph (f)(1) of this AD, before further flight, 
replace the MLG with an airworthy part following British Aerospace 
Jetstream Series 3100 and 3200 Service Bulletin 32-JA960142, 
Revision No. 4, October 21, 2016.
    (3) The compliance times in paragraphs (f)(1)(i) and (ii) of 
this AD are presented in FC (landings). If the total FC have not 
been kept, multiply the total number of airplane hours time-in-
service (TIS) by 0.75 to calculate the FC. For the purposes of this 
AD:
    (i) 100 hours TIS x .75 = 75 FC; and
    (ii) 1,000 hours TIS x .75 = 750 FC.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this
