AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Fokker Model F.28 Mark 0070 and 0100 

airplanes. This AD requires a one-time 

inspection of the fuel lines located in 

the left and right main landing gear 

(MLG) bays to determine the clearance 

between the fuel and hydraulic lines. If 

necessary, this AD also requires an 

inspection of fuel lines for chafing, the 

replacement of a chafed fuel line with 

a new fuel line, and the repositioning of 

existing clamps and installation of 

additional clamps between the fuel and 

hydraulic lines. This AD results from a 

fuel leak found in the left MLG bay. We 

are issuing this AD to detect and correct 

inadequate clearance between fuel and 

hydraulic lines in the MLG bay, which 

could lead to chafing of a fuel line and 

fuel leakage. A fuel leak near hot brakes 

could result in a fire in the MLG bay. 

DATES: This AD becomes effective April 

3, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 3, 2007.

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to all Fokker Model F.28 Mark 

0070 and 0100 airplanes. That NPRM 

was published in the Federal Register 

on November 20, 2006 (71 FR 67077). 

That NPRM proposed to require a onetime inspection of the fuel lines located 

in the left and right main landing gear 

bays to determine the clearance between 

the fuel and hydraulic lines. If 

necessary, that NPRM proposed to 

require an inspection of fuel lines for 


cprice-sewell on PROD1PC66 with RULES
8618 Federal Register / Vol. 72, No. 38 / Tuesday, February 27, 2007 / Rules and Regulations 

chafing, the replacement of a chafed fuel 

line with a new fuel line, and the 

repositioning of existing clamps and 

installation of additional clamps 

between the fuel and hydraulic lines. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

This AD affects about 9 airplanes of 

U.S. registry. The required inspection 

takes about 1 work hour per airplane, at 

an average labor rate of $80 per work 

hour. Based on these figures, the 

estimated cost of this AD for U.S. 

operators is $720, or $80 per airplane. 

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 have 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 

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. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

Accomplishment Instructions of Fokker 

Service Bulletin SBF100–28–041, dated July 

20, 2005. If the clearance of a fuel line is 3 

mm (millimeters) or more, no further action 

is required by this AD for that fuel line only. 

If the clearance of a fuel line is less than 3 

mm, before further flight, do a general visual 

inspection of the fuel line for chafing in 

accordance with Part 1 of the 

Accomplishment Instructions of the service 

bulletin. 

Note 1: For the purposes of this AD, a 

general visual inspection is: ‘‘A visual 

examination of an interior or exterior area, 

installation, or assembly to detect obvious 

damage, failure, or irregularity. This level of 

inspection is made from within touching 

distance unless otherwise specified. A mirror 

may be necessary to ensure visual access to 

all surfaces in the inspection area. This level 

of inspection is made under normally 

available lighting conditions such as 

daylight, hangar lighting, flashlight, or 

droplight and may require removal or 

opening of access panels or doors. Stands, 

ladders, or platforms may be required to gain 

proximity to the area being checked.’’

Corrective Actions 

(g) If the fuel line is found chafed during 

the inspection for chafing specified in 

paragraph (f) of this AD, before further flight 

after that inspection, do the actions in 

paragraphs (g)(1) and (g)(2) of this AD. If the 

fuel line is not found chafed, within 6 

months after the inspection for chafing, do 

the actions in paragraph (g)(2) of this AD.

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Bombardier Model DHC–8–100 (as 

described above), DHC–8–200, and 

DHC–8–300 series airplanes. This AD 

requires doing a one-time inspection for 

damage of the electrical cable harness 

assembly located on the left and right 

wing root-to-fuselage aft seal, and repair 

if necessary; and reworking the fuselage 

aft seal assembly (left and right) to 

create a clearance between the electrical 

cable assemblies and the edge of the 

fairing panel. This AD results from a 

report that an airplane encountered an 

uncommanded propeller feathering 

during climb, which resulted in an 

emergency landing. We are issuing this 

AD to prevent chafing or grounding of 

the wiring against the aft seal 

assemblies, which, if not corrected, 

could interrupt the operation of various 

systems, including the propeller feather 

control, alternating current (AC) 

electrical power, and standby hydraulic 

power, and result in reduced 

controllability of the airplane. 

DATES: This AD becomes effective April 

3, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 3, 2007.

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to certain Bombardier Model 

DHC–8–102, –103, and –106 airplanes, 

and Model DHC–8–200 and DHC–8–300
