ACTION: Final rule. AGENCY: 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: Bombardier Aerospace has completed a system safety review of the CL–600–2B19 aircraft fuel system * * *. The assessment showed that if the fuel boost pump reducer coupling is anodized, insufficient electrical bonding between the boost pump canister and the pressure pickup line could occur. Insufficient electrical bonding between the boost pump canister and the pressure pick-up line, if not corrected, could result in arcing and potential ignition source inside the fuel tank during lightning strikes and consequent fuel tank explosion. * * * We are issuing this AD to require actions to correct the unsafe condition on these products.

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 November 13, 2007 (72 FR 63834). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Bombardier Aerospace has completed a system safety review of the CL–600–2B19 aircraft fuel system against new fuel tank safety standards introduced in Chapter 525 of the Airworthiness Manual through Notice of Proposed Amendment (NPA) 2002–043. The identified non-compliances were assessed using Transport Canada Policy Letter No. 525–001 to determine if mandatory corrective action is required. The assessment showed that if the fuel boost pump reducer coupling is anodized, insufficient electrical bonding between the boost pump canister and the pressure pickup line could occur. Insufficient electrical bonding between the boost pump canister and the pressure pick-up line, if not corrected, could result in arcing and potential ignition source inside the fuel tank during lightning strikes and consequent fuel tank explosion. To correct the unsafe condition, this directive mandates a detailed visual inspection of the fuel boost pump for the presence of anodized reducer couplings. All anodized couplings found are to be replaced with couplings having ion vapor deposition (IVD) coating. 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 E:\FR\FM\22JAR1.SGM 22JAR1

Airworthiness Directives; McDonnell Douglas Model 717-200 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
McDonnell Douglas Model 717-200 airplanes. This AD requires electrical 
bonding of the fill valves for the right and left main fuel tanks, the 
fill valve and pipe assembly for the center wing fuel tank, and the 
defuel shutoff valve. This AD results from a fuel system review 
conducted by the manufacturer. We are issuing this AD to prevent 
improper bonding of the fill valves and defuel shutoff valve for the 
main fuel tanks and center wing tank, which, in combination with a 
lightning strike, could result in a fuel tank explosion and consequent 
loss of the airplane.

DATES: This AD is effective February 26, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 26, 
2008.

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 McDonnell Douglas Model 717-200 airplanes. That NPRM was 
published in the Federal Register on October 11, 2007 (72 FR 57894). 
That NPRM proposed to require electrical bonding of the fill valves for 
the right and left main fuel tanks, the fill valve and pipe assembly 
for the center wing fuel tank, and the defuel shutoff valve.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the single comment received. AirTran Airways 
supports the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD as proposed.

Costs of Compliance

    There are about 134 airplanes of the affected design in the 
worldwide fleet. This AD affects about 104 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 $9 
per airplane. Based on these figures, the estimated cost of the AD for 
U.S. operators is $34,216, or $329 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

    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.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.
