[Federal Register Volume 82, Number 32 (Friday, February 17, 2017)] [Proposed Rules] [Pages 10973-10976] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-02771] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0053; Directorate Identifier 2016-CE-037-AD] RIN 2120-AA64 Airworthiness Directives; British Aerospace Regional Aircraft Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model HP 137 Jetstream MK1, Jetstream Series 200, and Jetstream Series 3101 airplanes that would supersede AD 2014-07-07. This proposed AD results from 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 cracking of the forward main landing gear yoke pintle resulting from corrosion pits leading to stress corrosion cracking. We are issuing this proposed AD to require actions to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by April 3, 2017.

We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to http://regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On April 4, 2014, we issued AD 2014-07-07, Amendment 39-17821 (79 FR 23897; April 29, 2014) (``2014-07-07''). That AD required actions intended to address an unsafe condition on British Aerospace Regional Aircraft Model HP 137 Jetstream MK1, Jetstream Series 200, and Jetstream Series 3101 airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. Since we issued AD 2014-07-07, additional stress corrosion cracking in the pintle housing has been found that may not be detected during the current inspection procedures. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2016-0224, dated November 9, 2016 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states: 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 AD retains the requirements of EASA AD 2013-0208, which is superseded, and requires MLG inspections in accordance with the improved procedure. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-0053. Related Service Information Under 1 CFR Part 51 British Aerospace Regional Aircraft has issued 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 this NPRM. FAA's Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed 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 proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under the DOT Regulatory Policies and [[Page 10975]] 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, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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 removing Amendment 39-17821 (82 FR 23897; April 29, 2014), and adding the following new AD: British Aerospace Regional Aircraft: Docket No. FAA-2017-0053; Directorate Identifier 2016-CE-037-AD. (a) Comments Due Date We must receive comments by April 3, 2017. (b) Affected ADs This AD replaces 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. (d) Subject Air Transport Association of America (ATA) Code 32: Landing 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 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 paragraph 2.B. Part A of British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-A- JA851226, Revision 7, dated May 25, 2015. (2) For all airplanes: Within 300 landings after a heavy or abnormal landing or 3 months after a heavy or abnormal landing, whichever occurs first, do a NDT inspection of each MLG assembly cylinder attachment spigot housing following the accomplishment instructions in paragraph 2.B.

(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. Service Bulletin 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.
