Airworthiness Directives; Bombardier, Inc., Airplanes, 10449-10451 [2019-05209]

Download as PDF Federal Register / Vol. 84, No. 55 / Thursday, March 21, 2019 / Proposed Rules following requirements apply for review, approval, and posting of programmatic indirect cost rate waivers: (i) Program qualifications. Programs that have instituted a program-wide requirement and governance process for deviations from federally negotiated indirect cost rates may qualify for a programmatic deviation approval. (ii) Deviation requests. Deviation requests must be submitted by the responsible senior program manager to the DOI Office of Grants Management. The request for deviation approval must include a description of the program, and the governance process for negotiating and/or communicating to recipients the indirect cost rate requirements under the program. The program must make its governance documentation, rate deviations, and other program information publicly available. (iii) Approvals. Programmatic deviations must be approved, in writing, by the Director, Office of Grants Management. Approved deviations will be made publicly available. (4) Voluntary indirect cost rate reduction. On any single award, an applicant and/or proposed recipient may elect to reduce or eliminate the indirect cost rate applied to costs under that award. The election must be voluntary and cannot be required by the awarding official, NOFO, program, or other non-statutory or non-regulatory requirements. For these award-specific and voluntary reductions, DOI can accept the lower rate provided the notice of award clearly documents the recipient’s voluntary election. Once DOI has accepted the lower rate, that rate will apply for the duration of the award. (5) Unrecovered indirect costs. In accordance with 2 CFR 200.405, indirect costs not recovered due to deviations to the federally negotiated rate are not allowable for recovery via any other means. § § 1402.415–1402.499 [Reserved] amozie on DSK9F9SC42PROD with PROPOSALS Susan Combs, Senior Advisor to the Secretary, exercising the authority of the Assistant Secretary for Policy Management and Budget.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2018–21R1, effective November 1, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model DHC–8–400 series airplanes. The MCAI states: During a scheduled aileron inspection, a crack was found in the right-hand outboard spoiler bracket of an in-service aircraft. An investigation concluded that the crack was caused by low load, high cycle fatigue. A cracked bracket could cause inoperability or jam of a single spoiler panel and possible jam of the aileron circuit. This condition, if not corrected, could adversely affect the continued safe operation and landing of the aeroplane. The original version of this [Canadian] AD required initial and repetitive inspections of the outboard spoiler brackets, and required E:\FR\FM\21MRP1.SGM 21MRP1 10450 Federal Register / Vol. 84, No. 55 / Thursday, March 21, 2019 / Proposed Rules replacement of any brackets found cracked. It also required replacement of the brackets with a new design, which terminates the inspection requirement. Revision 1 of this [Canadian] AD is issued to correct an error in the date of Service Bulletin (SB) 84–27–72 Revision A. This [Canadian] AD also clarifies the part numbers of the outboard spoiler actuator brackets and their assemblies. The bracket replacement includes related investigative actions (inspecting for damage of the fastener holes in the rear spar web) and corrective actions (oversizing holes or other repair). You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0120. Related Service Information Under 1 CFR Part 51 Bombardier has issued Service Bulletin 84–27–72, Revision A, dated November 9, 2017. This service information describes procedures for repetitively inspecting the left and right outboard spoiler actuator mounting brackets for cracks, replacing cracked brackets, and eventually replacing all brackets with re-designed parts, and related investigative and corrective actions. 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. referenced above. We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. FAA’s Determination Costs of Compliance 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 the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information We estimate that this proposed AD affects 53 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in the service information described previously.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2018-21R1, effective 
November 1, 2018 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc., Model DHC-8-400 series 
airplanes. The MCAI states:

    During a scheduled aileron inspection, a crack was found in the 
right-hand outboard spoiler bracket of an in-service aircraft. An 
investigation concluded that the crack was caused by low load, high 
cycle fatigue. A cracked bracket could cause inoperability or jam of 
a single spoiler panel and possible jam of the aileron circuit. This 
condition, if not corrected, could adversely affect the continued 
safe operation and landing of the aeroplane.
    The original version of this [Canadian] AD required initial and 
repetitive inspections of the outboard spoiler brackets, and 
required

[[Page 10450]]

replacement of any brackets found cracked. It also required 
replacement of the brackets with a new design, which terminates the 
inspection requirement.
    Revision 1 of this [Canadian] AD is issued to correct an error 
in the date of Service Bulletin (SB) 84-27-72 Revision A. This 
[Canadian] AD also clarifies the part numbers of the outboard 
spoiler actuator brackets and their assemblies.

The bracket replacement includes related investigative actions 
(inspecting for damage of the fastener holes in the rear spar web) and 
corrective actions (oversizing holes or other repair). You may examine 
the MCAI in the AD docket on the internet at https://www.regulations.gov 
by searching for and locating Docket No. FAA-2019-0120.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 84-27-72, Revision A, dated 
November 9, 2017. This service information describes procedures for 
repetitively inspecting the left and right outboard spoiler actuator 
mounting brackets for cracks, replacing cracked brackets, and 
eventually replacing all brackets with re-designed parts, and related 
investigative and corrective actions.
    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.

FAA's Determination

    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 the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 53 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes and associated appliances to the 
Director of the System Oversight Division.

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:

having outboard spoiler actuator brackets with part numbers 
85714052-101 or 85714052-102.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Reason

    This AD was prompted by a report of a cracked outboard spoiler 
actuator mounting bracket. We are issuing this AD to address 
cracking of the outboard spoiler actuator mounting brackets, which 
could cause inoperability or jam of a single spoiler panel and 
possible jam of the aileron circuit. This condition, if not 
corrected, could adversely affect the continued safe operation and 
landing of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Repetitive Inspections

    At the applicable time specified in paragraph (g)(1) or (g)(2) 
of this AD: Do a general visual inspection for cracks in the left 
and right outboard spoiler actuator mounting brackets having part 
number (P/N) 85714052-101 or 85714052-102 (belonging to assemblies 
having P/N 85714018-001 or P/N 85714018-002, respectively), in 
accordance with Section 3.B, Part A, of the Accomplishment 
Instructions of Bombardier Service Bulletin 84-27-72, Revision A, 
dated November 9, 2017. Repeat the inspection thereafter at 
intervals not to exceed 8,000 flight hours.
    (1) For airplanes having less than 12,000 total flight hours as 
of the effective date of this AD: Prior to the accumulation of 
18,000 total flight hours.
    (2) For airplanes having 12,000 total flight hours or more as of 
the effective date of this AD: Within 6,000 flight hours after the 
effective date of this AD.

(h) Part Replacement

    (1) If, during any inspection required by paragraph (g) of this 
AD, either the left or right outboard spoiler actuator mounting 
bracket is found cracked: Before further flight, replace both the 
left and right brackets with new bracket assemblies having P/N 
85714018-003 or P/N 85714018-004, including doing all applicable 
related investigative actions and corrective actions, in accordance 
with Section 3.B, Part B, of the Accomplishment Instructions of 
Bombardier Service Bulletin 84-27-72, Revision A, dated November 9, 
2017; except, where the service information specifies contacting 
Bombardier for corrective action, this AD requires accomplishing the 
action using a method approved by the Manager, New York ACO Branch, 
FAA; or Transport Canada Civil Aviation (TCCA); or Bombardier, 
Inc.'s TCCA Design Approval Organization (DAO). If approved by the 
DAO, the approval must include the DAO-authorized signature.
    (2) If, during any inspection required by paragraph (g) of this 
AD, no cracking is found on the left and right outboard spoiler 
actuator mounting brackets, and the left and right outboard spoiler 
actuator mounting brackets have not already been replaced per the 
requirements of paragraph (h)(1) of this AD: Replace both the left 
and right brackets with new bracket assemblies having P/N 85714018-
003 or P/N 85714018-004, including doing all applicable related 
investigative actions and corrective actions, at the applicable time 
specified in paragraph (h)(2)(i) or (h)(2)(ii) of this AD, in 
accordance with Section 3.B, Part B, of the Accomplishment 
Instructions of Bombardier Service Bulletin 84-27-72, Revision A, 
dated November 9, 2017; except, where the service information 
specifies contacting Bombardier for corrective action, this AD 
requires accomplishing the action using a method approved by the 
Manager, New York ACO Branch, FAA; or TCCA; or Bombardier, Inc.'s 
TCCA DAO. If approved by the DAO, the approval must include the DAO-
authorized signature. Related investigative and corrective actions 
must be done before further flight.
    (i) For airplanes that have accumulated less than 34,000 total 
flight hours as of the effective date of this AD: Replace the 
outboard spoiler actuator mounting brackets prior to the airplane 
accumulating 40,000 total flight hours.

hours or more as of the effective date of this AD: Replace the 
outboard spoiler actuator mounting brackets within 6,000 flight 
hours after the effective date of this AD.

(i) Terminating Action for Repetitive Inspections

    Replacement of an outboard spoiler actuator mounting bracket, in 
accordance with the requirements of paragraph (h) of this AD, is 
terminating action for the repetitive inspections required by 
paragraph (g) of this AD for the replaced bracket.

(j) Credit for Previous Actions

    This paragraph provides credit for the actions required by 
paragraphs (g) and (h) of this AD, if those actions were performed
