Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model DHC–8–400 

series airplanes. This AD was prompted 

by reports of inadvertent deployment of 

a single outboard spoiler during flight. 

This AD requires replacement of the 

power control units (PCUs) for the 

outboard spoilers with upgraded PCUs. 

We are issuing this AD to prevent 

leakage of the piston head seal and 

piston rod seals of the outboard spoiler 

PCUs, which could result in inadvertent 

spoiler deployment and reduced 

controllability of the airplane. 

DATES: This AD becomes effective 

November 3, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 3, 2015.

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 certain Bombardier, Inc. Model 

DHC–8–400 series airplanes. The NPRM 

published in the Federal Register on 

March 24, 2015 (80 FR 15521). 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2014–22, 

dated July 16, 2014 (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: 

Although [Canadian] AD CF–2009–26 

[dated May 21, 2009 (http://

wwwapps3.tc.gc.ca/Saf-Sec-Sur/2/CAWISSWIMN/attachment.asp?aiid=CF-2009- 

26&revid=0&cntr=CF&file=CFCF-2009- 

26.pdf&type=PDE), which corresponds to 

FAA AD 2009–25–05, Amendment 39–16124

Federal Register / Vol. 80, No. 188 / Tuesday, September 29, 2015 / Rules and Regulations 58345 

(74 FR 63574, December 4, 2009)] was issued 

to mandate the upgrade of the spoiler lift/

dump valve, it did not reduce the rate of 

inadvertent single spoiler deployment 

occurrences. Further investigation revealed 

that the outboard spoiler PCUs may also be 

subject to pressure reversals at the PCU main 

control valve seal, resulting in leakage at the 

piston head seal and piston rod seals. If not 

corrected, this condition may result in 

[inadvertent spoiler deployment and] 

reduced controllability of the aeroplane. 

This [Canadian] AD mandates the 

replacement of the existing outboard spoiler 

PCUs with the upgraded PCUs with redesigned seals for better leakage protection. 

You may examine the MCAI in the 

AD docket on the Internet at http://

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comment 

received on the NPRM (80 FR 15521, 

March 24, 2015) and the FAA’s response 

to that comment. 

Request To Revise Applicability 

Horizon Air requested that the 

applicability of the NPRM (80 FR 15521, 

March 24, 2015) be revised to specify 

that the NPRM would only be 

applicable to airplanes with outboard 

spoiler PCU part number (P/N) 390700– 

1007 installed. The commenter noted 

that the illustrated parts catalog for the 

Bombardier, Inc. Model DHC–8–400 

series airplanes indicates that outboard 

spoiler PCU P/N 390700–1009 is a 

direct replacement for P/N 390700– 

1007, and that these two part numbers 

are one way interchangeable. The 

commenter stated that operators who 

replaced outboard spoiler PCU P/N 

390700–1007 with P/N 390700–1009 

prior to the effective date of the NPRM 

might not have recorded the 

incorporation of Bombardier Service 

Bulletin 84–27–63, dated October 17, 

2013, into their maintenance records 

and it would be an unnecessary 

regulatory burden for those operators to 

go back and record this service 

information. The Accomplishment 

Instructions of Bombardier Service 

Bulletin 84–27–63, dated October 17, 

2013, state that the PCU should be 

replaced using the guidance in the 

Bombardier, Inc. Model DHC–8–400 

Aircraft Maintenance Manual; therefore 

the actions that would be mandated by 

the NPRM would have been 

accomplished. 

We agree with the commenter’s 

request based on the information 

provided by the commenter. We have 

revised paragraph (c), ‘‘Applicability,’’ 

of this final rule to specify that only 

airplanes having certain serial numbers 

and an outboard spoiler PCU having P/ 

N 390700–1007 installed are affected by 

the requirements of this final rule. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

with the change described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (80 FR 

15521, March 24, 2015) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 15521, 

March 24, 2015). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD. 

Related Service Information Under 1 

CFR Part 51 

Bombardier, Inc. has issued Service 

Bulletin 84–27–63, dated October 17, 

2013. The service information describes 

procedures for replacement of the 

existing outboard spoiler PCUs with 

upgraded PCUs. 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 AD. 

Costs of Compliance 

We estimate that this AD affects 82 

airplanes of U.S. registry. 

We also estimate that it will take 

about 4 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Required parts will cost 

about $0 per product. Based on these 

figures, we estimate the cost of this AD 

on U.S. operators to be $27,880, or $340 

per product. 

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 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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 767 

airplanes. This AD was prompted by 

reports that six fasteners may not have 

been installed in the left and right 

stringer 37 (S–37) between body stations 

(BS) 428 and 431 lap splices on certain 

airplanes. This AD requires a general 

visual inspection of S–37 lap splices for 

missing fasteners, and all applicable 

related investigative and corrective 

actions. We are issuing this AD to detect 

and correct missing fasteners, which 

could result in cracks in the fuselage 

skin that could adversely affect the 

structural integrity of the airplane. 

DATES: This AD is effective November 3, 

2015. 

The Director of the Federal Register
