2018-20-16: Hydraulic Power

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 removing Airworthiness Directive (AD) 2013-11-12, Amendment 39-17472 (78 [[Page 52759]] FR 33206, June 4, 2013), and adding the following new AD: 2018-20-16 Bombardier, Inc.: Amendment 39-19450; Docket No. FAA- 2018-0161; Product Identifier 2017-NM-088-AD. (a) Effective Date This AD is effective November 23, 2018. (b) Affected ADs This AD replaces AD 2013-11-12, Amendment 39-17472 (78 FR 33206, June 4, 2013) (``AD 2013-11-12''). (c) Applicability This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, having serial numbers 20003 through 20604 inclusive. (d) Subject Air Transport Association (ATA) of America Code 29, Hydraulic Power. (e) Reason This AD was prompted by reports of failure of a screw cap or end cap of the hydraulic system accumulator while on the ground, which resulted in loss of use of that hydraulic system and high-energy impact damage to adjacent systems and structures. We are issuing this AD to prevent failure of a screw cap or end cap and loss of the related hydraulic system, which could result in damage to airplane structure and consequent reduced controllability of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Inspection With No ChangesThis paragraph restates the requirements of paragraph (g) of AD 2013-11-12 with no changes. For airplanes having serial numbers 20003 through 20335 inclusive: At the applicable time specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD: Inspect the identification plate on the hydraulic system accumulator having part number (P/N) 900095-1 to determine if an ``E'' is part of the suffix of the serial number stamped on the identification plate, as listed in paragraph 2.B. of the Accomplishment Instructions of Bombardier Service Bulletin 100-29-14, dated December 16, 2010. A review of airplane maintenance records is acceptable in lieu of this inspection if the suffix of the serial number can be conclusively determined from that review. (1) For an accumulator that has accumulated more than 3,150 total flight cycles as of July 9, 2013 (the effective date of AD 2013-11-12), inspect that accumulator within 350 flight cycles after July 9, 2013. (2) For an accumulator that has accumulated 3,150 or fewer total flight cycles as of July 9, 2013 (the effective date of AD 2013-11- 12), inspect that accumulator before it has accumulated 3,500 total flight cycles. (3) For an accumulator on which it is not possible to determine the total flight cycles accumulated as of July 9, 2013 (the effective date of AD 2013-11-12), inspect that accumulator within 350 flight cycles after July 9, 2013. (h) Retained Replacement With No Changes This paragraph restates the requirements of paragraph (h) of AD 2013-11-12 with no changes. If, during the inspection required by paragraph (g) of this AD, any accumulator having P/N 900095-1 is found on which the letter ``E'' is not part of the suffix of the serial number on the identification plate: Before further flight, replace the accumulator with a new or serviceable accumulator, in accordance with paragraph 2.C. of the Accomplishment Instructions of Bombardier Service Bulletin 100-29-14, dated December 16, 2010. (i) Retained Parts Installation Prohibition With No Changes This paragraph restates the requirements of paragraph (i) of AD 2013-11-12 with no changes. For airplanes having serial numbers 20003 through 20335 inclusive: As of July 9, 2013 (the effective date of AD 2013-11-12), no person may install on any airplane a hydraulic system accumulator having P/N 900095-1, on which the letter ``E'' is not part of the suffix of the serial number on the identification plate. (j) New Requirement of This AD: Replacement of Brake System Hydraulic Accumulators For airplanes having serial numbers 20003 through 20347 inclusive: At the applicable time specified in paragraph (j)(1), (j)(2), or (j)(3) of this AD, replace all brake system hydraulic accumulators having P/N 33-147500 or P/N 33-155500 that are not identified by the letter ``E'' or ``NAE'' after the serial number on the identification plate with an accumulator of the same part number that is identified by the letter ``E'' or ``NAE'' after the serial number. Do the replacement in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 100-32-21, dated May 24, 2012. (1) For an accumulator that has accumulated more than 4,700 total flight cycles as of the effective date of this AD, inspect that accumulator within 300 flight cycles after the effective date of this AD. (2) For an accumulator that has accumulated 4,700 or fewer total flight cycles as of the effective date of this AD, inspect that accumulator before it has accumulated 5,000 total flight cycles. (3) For an accumulator on which it is not possible to determine the total flight cycles accumulated as of the effective date of this AD, inspect that accumulator within 300 flight cycles after the effective date of this AD. (k) New Requirement of This AD: Additional Parts Installation Prohibition For airplanes having serial numbers 20003 through 20347 inclusive: As of the effective date of this AD, no person may install on any airplane a hydraulic system accumulator having P/N 33-147500 or P/N 33-155500, on which the letter ``E'' or ``NAE'' is not after the serial number on the identification plate. (l) New Requirement of This AD: Modification of the Inboard and Outboard Brake Accumulators For airplanes having serial numbers 20003 through 20395 inclusive: Within 1,600 flight hours or 14 months after the effective date of this AD, whichever occurs first, modify (re- orient) the installation of the inboard and outboard brake accumulators, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 100-32-20, Revision02, dated April 14, 2015. (m) Credit for Previous Actions This paragraph provides credit for the actions specified in paragraph (l) of this AD, if those actions were performed before the effective date of this AD using Bombardier Service Bulletin 100-32- 20, dated February 25, 2013; or Revision 01, dated March 5, 2015. (n) New Requirement of This AD: Maintenance or Inspection Program Revision For airplanes having serial numbers 20003 through 20604 inclusive: Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, to incorporate life limit tasks 29-21-13-101, 32-43-37-101, and 32-44- 05-101 of Section 5-10-11 of Part 2, ``Airworthiness Limitations'', of Bombardier Challenger 300 BD-100 Time Limits/Maintenance Checks Manual, Revision 17, dated December 15, 2016; or Bombardier Challenger 350 BD-100 Time Limits/Maintenance Checks Manual, Revision 9, dated December 18, 2017, as applicable.
