Airworthiness Directives; Viking Air 

Limited Model DHC–7 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This 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: 

Transport Canada has received numerous 

service difficulty reports concerning Viking 

DHC–7 and Bombardier DHC–8 aircraft 

fluorescent lamp holder damage due to 

overheating. It has been determined that 

lamp holder overheating is a result of arcing 

between the fluorescent tube pins and the 

lamp holder contacts when the tube is not 

properly seated during installation. 

Overheating of lamp holders, if not corrected, 

could generate fumes and smoke * * *. 

* * * * * 

The unsafe condition could result in 

an in-flight fire. We are issuing this AD 

to require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective April 

20, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 20, 2009.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on December 23, 2008 (73 FR 

78673). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Transport Canada has received numerous 

service difficulty reports concerning Viking 

DHC–7 and Bombardier DHC–8 aircraft 

fluorescent lamp holder damage due to 

overheating. It has been determined that 

lamp holder overheating is a result of arcing 

between the fluorescent tube pins and the 

lamp holder contacts when the tube is not 

properly seated during installation. 

Overheating of lamp holders, if not corrected, 

could generate fumes and smoke, causing 

concern to passengers and crew. 

This directive mandates repetitive 

inspection[s] for proper installation [and 

functioning] of fluorescent tubes and 

prohibits installation of non-arc-protected 

replacement fluorescent lamp ballasts. 

The unsafe condition could result in 

an in-flight fire. The corrective actions 

include replacing any lamps that are not 

properly seated in the lamp holder, and 

replacing any broken, non-functioning 

lamp holders. Replacing all affected 

fluorescent lamp ballasts would 

terminate the repetitive inspections. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

11012 Federal Register / Vol. 74, No. 49 / Monday, March 16, 2009 / Rules and Regulations 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

21 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Based on these figures, we estimate the 

cost of this AD to the U.S. operators to 

be $1,680, or $80 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 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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt. 

List of Subjects in 14 CFR Part 39

safety, Incorporation by reference, 

Safety. 

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 

■ 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 adding 

the following new AD: 

2009–06–03 Viking Air Limited (Formerly 

Bombardier, Inc.): Amendment 39– 

15839. Docket No. FAA–2008–1330; 

Directorate Identifier 2008–NM–138–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 20, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Viking Air Limited 

Model DHC–7–1, DHC–7–100, DHC–7–101, 

DHC–7–102, and DHC–7–103 airplanes, 

certificated in any category; serial numbers 1 

through 113 inclusive, with Modifications 7/ 

2444 and 7/2445 incorporated. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 33: Lights. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

‘‘Transport Canada has received numerous 

service difficulty reports concerning Viking 

DHC–7 and Bombardier DHC–8 aircraft 

fluorescent lamp holder damage due to 

overheating. It has been determined that 

lamp holder overheating is a result of arcing 

between the fluorescent tube pins and the 

lamp holder contacts when the tube is not 

properly seated during installation. 

Overheating of lamp holders, if not corrected, 

could generate fumes and smoke, causing 

concern to passengers and crew. 

This directive mandates repetitive 

inspection[s] for proper installation [and 

functioning] of fluorescent tubes and 

prohibits installation of non-arc-protected 

replacement fluorescent lamp ballasts.’’ 

The unsafe condition could result in an inflight fire. The corrective actions include 

replacing any lamps that are not properly 

seated in the lamp holder, and replacing any 

broken, non-functioning lamp holders. 

Replacing all affected fluorescent lamp 

ballasts would terminate the repetitive 

inspections. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 1,000 flight hours after the 

effective date of this AD: Perform a visual 

inspection to ensure proper installation and 

functioning of the fluorescent tubes in the 

lamp holders, and perform all applicable 

corrective actions before further flight, in 

accordance with the Accomplishment 

Instructions of Viking Service Bulletin V7– 

33–01, dated February 28, 2008. Repeat the 

inspection thereafter at intervals not to 

exceed 1,000 flight hours. 

(2) Replacing all fluorescent lamp ballasts 

having part number (P/N) BAO8006–1 and 

BA[O]8006–28–1 with new fluorescent lamp 

ballasts having P/N BR9000–21, in 

accordance with the Accomplishment 

Instructions of Viking Service Bulletin V7– 

33–01, dated February 28, 2008, terminates 

the repetitive inspections required by 

paragraph (f)(1) of this AD.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Boeing Model 747–100, 747–100B, 747– 

100B SUD, 747–200B, 747–200C, 747– 

200F, 747–300, 747–400, 747SR, and 

747SP series airplanes. This AD requires 

inspecting for skin cracks at the shear 

tie end fastener locations of the fuselage 

frames, and repairing cracks if 

necessary. This AD results from a widespread fatigue damage assessment of 

Model 747 airplanes. We are issuing this 

AD to detect and correct cracks in the 

fuselage skin that can propagate and 

grow, resulting in a loss of structural 

integrity and a sudden decompression 

of the airplane during flight. 

DATES: This AD is effective April 20, 

2009.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to 

certain Boeing model 747–100, 747– 

100B, 747–100B SUD, 747–200B, 747– 

200C, 747–200F, 747–300, 747–400, 

747SR, and 747SP series airplanes. That 

NPRM was published in the Federal 

Register on October 8, 2008 (73 FR 

58901). That NPRM proposed to require 

inspecting for skin cracks at the shear 

tie end fastener locations of the fuselage 

frames, and repairing cracks if 

necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. 

Boeing concurs with the contents of the 

NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

We estimate that this AD affects 147 

airplanes of U.S. registry. We also 

estimate that it takes 30 work-hours for 

the detailed inspection, or 49 work 

hours for the HFEC inspection, per 

product, to comply with this AD. The 

average labor rate is $80 per work-hour. 

Based on these figures, we estimate the 

cost of this AD to the U.S. operators to 

be $352,800 or $576,240, or $2,400 or 

$3,920 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
