SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the airworthiness directive (AD) docket on the Internet at https://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section. 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 series airplanes. That NPRM was published in the Federal Register on December 11, 2006 (71 FR 71492). That NPRM proposed to require doing a onetime inspection for damage of the electrical cable harness assembly located on the left and right wing rootto-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. Comments We provided the public the opportunity to participate in the development of this AD. We received no PO 00000 Frm 00035 Fmt 4700 Sfmt 4700 8619 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 136 airplanes of U.S. registry. The required actions take about 4 work hours per airplane, at an average labor rate of $80 per work hour. Required parts cost about $75 per airplane. Based on these figures, the estimated cost of this AD for U.S. operators is $53,720, or $395 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.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This AD requires repetitive inspections of the bolts that attach the exhaust nozzle to the aft engine flange to determine if any bolts are missing or fractured, and replacement of the existing bolts with new, improved bolts. This AD results from reports of the engine exhaust nozzle and fairing departing from the airplane in flight due to missing attachment bolts. We are issuing this AD to detect and correct missing or fractured attachment bolts, which could lead to the loss of an engine exhaust nozzle during flight and consequent structural damage to the airplane and hazard to people or property on the ground. Damage to the airplane could cause the airplane to yaw and result in reduced controllability of the airplane. DATES: This AD becomes effective April 3, 2007.

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.

(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

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 series airplanes. That NPRM was published in the Federal Register 
on December 11, 2006 (71 FR 71492). That NPRM proposed to require 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.

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 136 airplanes of U.S. registry. The required 
actions take about 4 work hours per airplane, at an average labor rate 
of $80 per work hour. Required parts cost about $75 per airplane. Based 
on these figures, the estimated cost of this AD for U.S. operators is 
$53,720, or $395 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
