ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2014–05– 

28, which applied to certain 

Bombardier, Inc., Model DHC–8–400 

series airplanes. AD 2014–05–28 

required revising the maintenance or 

inspection program, as applicable. This 

AD requires revising the maintenance or 

inspection program, as applicable, to 

include a revised task. This AD was 

prompted by a determination that the 

interval from Maintenance Review 

Board (MRB) task number 323100–202 

should not be escalated, and that 

Certification Maintenance Requirements 

(CMR) task number 323100–102 should 

be applicable to all Model DHC–8–400 

series airplanes, regardless of which 

main landing gear (MLG) up-lock 

assembly is installed. We are issuing 

this AD to address the unsafe condition 

on these products. 

DATES: This AD is effective September 

25, 2018. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 25, 2018.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2014–05–28, 

Amendment 39–17800 (79 FR 18611, 

April 3, 2014) (‘‘AD 2014–05–28’’). AD 

2014–05–28 applied to certain 

Bombardier, Inc., Model DHC–8–400 

series airplanes. The NPRM published 

in the Federal Register on February 9, 

2018 (83 FR 5746). The NPRM was 

prompted by our determination that the 

interval from MRB task number 323100– 

202 should not be escalated, and that 

CMR task number 323100–102 should 

be applicable to all Model DHC–8–400 

series airplanes, regardless of which 

MLG up-lock assembly is installed. 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD 


sradovich on DSK3GMQ082PROD with RULES
42210 Federal Register / Vol. 83, No. 162 / Tuesday, August 21, 2018 / Rules and Regulations 

CF–2017–15, effective May 29, 2017 

(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: 

[Canadian] AD CF–2012–21 [which 

corresponds to FAA AD 2014–05–28] was 

issued to mandate the incorporation of 

Maintenance Review Board (MRB) task 

number 323100–202. As in-service 

experience has shown that the interval for 

MRB task number 323100–202 should not be 

escalated, Bombardier has introduced onestar CMR task number 323100–102 to prevent 

task escalation. Bombardier has also revised 

the applicability of MRB task number 

323100–202 to be applicable to the entire 

DHC–8–400/-401/-402 fleet, regardless of 

which main landing gear (MLG) up-lock 

assembly part number is installed. This 

revised applicability has resulted in CMR 

task number 323100–102 also being made 

applicable to the entire DHC–8–400/-401/- 

402 fleet, regardless of MLG up-lock 

assembly part number installation. 

This [Canadian] AD mandates the 

incorporation of CMR task number 323100– 

102 [into the maintenance or inspection 

program, as applicable]. 

You may examine the MCAI in the 

AD docket on the internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2018– 

0072. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comment 

received on the NPRM and the FAA’s 

response to that comment. 

Request To Provide Actions for 

Operators With Task Already Included 

in Maintenance or Inspection Program 

Horizon Air requested that the 

proposed AD be revised to address 

operators that have already revised their 

maintenance or inspection program to 

include the information specified in 

CMR task number 323100–102 of Q400 

Dash 8 (Bombardier) Temporary 

Revision (TR) ALI–0168, dated October 

31, 2016 (‘‘Bombardier TR ALI–0168’’). 

The commenter stated that paragraphs 

(h) and (i) of the proposed AD 

established compliance times and a 

method for the initial functional check 

of CMR task number 323100–102. The 

commenter also noted that the method 

of compliance for the initial functional 

check in paragraph (i) of the proposed 

AD is based on accomplishing CMR task 

number ‘‘32100–202.’’ We infer the 

commenter meant CMR task number 

‘‘323100–102.’’ The commenter stated 

that this does not address operators that 

have the CMR task already in place. 

We do not agree with the commenter’s 

request. We contacted the commenter 

and, upon further discussion, it was 

determined that paragraph (i) of this AD 

does address the commenter’s request 

regarding what operators that already 

have CMR task number 323100–102 in 

place should do. The commenter stated 

that it originally submitted the comment 

based on a misunderstanding and it 

intended to withdraw the comment. We 

have not changed this AD regarding this 

issue. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting this 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 

Bombardier has issued Q400 Dash 8 

(Bombardier) Temporary Revision (TR) 

ALI–0168, dated October 31, 2016. The 

service information describes CMR task 

number 323100–102, ‘‘Functional Check 

of the Main Landing Gear Uplock 

Assembly Latch.’’ 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. 

Costs of Compliance 

We estimate that this AD affects 69 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

We have determined that revising the 

maintenance or inspection program 

takes an average of 90 work-hours per 

operator, although we recognize that 

this number may vary from operator to 

operator. In the past, we have estimated 

that this action takes 1 work-hour per 

airplane. Since operators incorporate 

maintenance or inspection program 

changes for their affected fleet(s), we 

have determined that a per-operator 

estimate is more accurate than a perairplane estimate. Therefore, we 

estimate the total cost per operator to be 

$7,650 (90 work-hours × $85 per workhour). 

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 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 to the Director of the System 

Oversight Division. 

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 that 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 


sradovich on DSK3GMQ082PROD with RULES
Federal Register / Vol. 83, No. 162 / Tuesday, August 21, 2018 / Rules and Regulations 42211 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Airworthiness Directive (AD) 

2014–05–28, Amendment 39–17800 (79 

FR 18611, April 3, 2014), and adding 

the following new AD: 

2018–17–09 Bombardier, Inc.: Amendment 

39–19363; Docket No. FAA–2018–0072; 

Product Identifier 2017–NM–082–AD. 

(a) Effective Date 

This AD is effective September 25, 2018. 

(b) Affected ADs 

This AD replaces AD 2014–05–28, 

Amendment 39–17800 (79 FR 18611, April 3, 

2014). 

(c) Applicability 

This AD applies to Bombardier, Inc., 

Model DHC–8–400, -401, and -402 airplanes, 

certificated in any category, serial numbers 

4001, 4003 and subsequent. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 32, Landing gear. 

(e) Reason 

This AD was prompted by reports of 

excessive wear on the lower latch surface of 

the main landing gear (MLG) up-lock hook. 

This AD was also prompted by a 

determination that, the maintenance or 

inspection program, as applicable, must be 

revised to include a new task. We are issuing 

this AD to detect and correct up-lock hooks 

worn beyond the wear limit, which could 

prevent the successful extension of the MLG 

using the primary landing gear extension 

system, which in combination with an 

alternate extension system failure could 

result in the inability to extend the MLG. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Maintenance or Inspection Program 

Revision 

Within 30 days after the effective date of 

this AD, revise the maintenance or inspection 

program, as applicable, to incorporate the 

information specified in Certification 

Maintenance Requirements (CMR) task 

number 323100–102 of Q400 Dash 8 

(Bombardier) Temporary Revision (TR) ALI– 

0168, dated October 31, 2016 (‘‘Bombardier 

TR ALI–0168’’). The applicable maintenance 

or inspection program revision required by 

this paragraph may be done by inserting a 

copy of Bombardier TR ALI–0168, to Section 

1–32, Landing Gear Maintenance Program, of 

Maintenance Review Board (MRB) Report 

Part 2, Bombardier Q400 Dash 8 Maintenance 

Requirements Manual, Product Support 

Manual (PSM) 1–84–7. When this temporary 

revision has been included in general 

revisions of the PSM, the general revisions 

may be inserted in the maintenance or 

inspection program, as applicable, provided 

the relevant information in the general 

revision is identical to that in Bombardier TR 

ALI–0168. 

(h) Initial Functional Check Compliance 

Times 

For MLG up-lock assembly latches that 

have accumulated flight cycles which exceed 

the CMR task number 323100–102 interval 

specified in Bombardier TR ALI–0168: 

Perform the initial CMR task number 

323100–102 functional check as specified in 

Bombardier TR ALI–0168 using the 

applicable compliance time specified in 

paragraph (h)(1), (h)(2), or (h)(3) of this AD. 

(1) For MLG up-lock assembly latches that 

have 14,200 total flight cycles or more as of 

the effective date of this AD: The compliance 

time for doing the initial functional check is 

within 800 flight cycles after the effective 

date of this AD. 

(2) For MLG up-lock assembly latches that 

have 11,600 total flight cycles or more, but 

fewer than 14,200 total flight cycles, as of the 

effective date of this AD: The compliance 

time for doing the initial functional check is 

within 1,600 flight cycles after the effective 

date of this AD, but not to exceed 15,000 total 

flight cycles on the up-lock assembly latch. 

(3) For MLG up-lock assembly latches with 

fewer than 11,600 total flight cycles as of the 

effective date of this AD: The compliance 

time for doing the initial functional check is 

within 3,000 flight cycles after the effective 

date of this AD, but not to exceed 13,200 total 

flight cycles on the up-lock assembly latch. 

(i) Method of Compliance for Initial 

Functional Check 

Accomplishing CMR task number 323100– 

102 of Bombardier TR MRB–66, dated 

December 7, 2011, to Section 1–32, Landing 

Gear Maintenance Program, of MRB Report 

Part 1, Bombardier Q400 Dash 8 Maintenance 

Requirements Manual, PSM 1–84–7, within 

3,000 flight cycles before the effective date of 

this AD, is a method of compliance for the 

initial functional check required by CMR task 

number 323100–102 as specified in
