Federal Register Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Cessna Model 500, 501, 550, S550, 551, and 560 airplanes. This AD requires revising the airplane flight manual (AFM) to prohibit use of the wing fuel boost pumps for defueling under certain conditions; installing a placard; doing other specified investigative and corrective actions as necessary; and modifying the boost pumps. This AD also requires the subsequent removal of the AFM revision and placard. This AD results from a report of a chafed electrical wiring harness, which was arcing inside the fuel tank. We are issuing this AD to prevent potential fuel vapor ignition in a fuel tank, which could result in explosion and loss of the airplane.

Airworthiness Directives; Cessna Model 500, 501, 550, S550, 551, 
and 560 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Cessna Model 500, 501, 550, S550, 551, and 560 airplanes. This 
AD requires revising the airplane flight manual (AFM) to prohibit use 
of the wing fuel boost pumps for defueling under certain conditions; 
installing a placard; doing other specified investigative and 
corrective actions as necessary; and modifying the boost pumps. This AD 
also requires the subsequent removal of the AFM revision and placard. 
This AD results from a report of a chafed electrical wiring harness, 
which was arcing inside the fuel tank. We are issuing this AD to 
prevent potential fuel vapor ignition in a fuel tank, which could 
result in explosion and loss of the airplane.

DATES: This AD becomes effective April 20, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 20, 
2006.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://dms.dot.gov">http://dms.dot.gov</a> or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street SW., Nassif Building, 
Room PL-401, Washington, DC.
    Contact Cessna Aircraft Co., P.O. Box 7706, Wichita, Kansas 67277, 
for service information identified in this AD.

FOR FURTHER INFORMATION CONTACT: Bryan Easterwood, Aerospace Engineer, 
Electrical Systems and Avionics Branch, ACE-119W, Wichita Aircraft 
Certification Office, FAA, 1801 Airport Road, room 100, Mid-Continent

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the AD docket on the Internet at <a href="http://dms.dot.gov">http://dms.dot.gov</a> 
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 supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that would apply to certain 
Cessna Model 500, 501, 550, S550, 551, and 560 airplanes. That 
supplemental NPRM was published in the Federal Register on October 25, 
2005 (70 FR 61580). That supplemental NPRM proposed to require revising 
the airplane flight manual (AFM) to prohibit use of the wing fuel boost 
pumps for defueling under certain conditions; installing a placard; 
doing other specified investigative and corrective actions as 
necessary; and modifying the boost pumps. That supplemental NPRM also 
would have required the subsequent removal of the AFM revision and 
placard.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the 
supplemental NPRM or on the determination of the cost to the public.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

[[Page 13527]]

Costs of Compliance

    There are about 2,397 airplanes of the affected design in the 
worldwide fleet; of these, 1,762 airplanes are U.S.-registered. The 
following table provides the estimated costs for U.S. operators to 
comply with this AD.

                                                                     Estimated Costs

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.

Placard Installation

    (h) Within 25 flight hours after the effective date of this AD: 
Install a placard close to the fuel quantity gauge, in accordance 
with the Accomplishment Instructions of the service bulletin. In 
addition to the specifications in the service bulletin, the letters 
on the placard must be at least \1/4\-inch tall.

Inspection and Modification

    (i) Within 300 flight hours after the effective date of this AD: 
Do the actions specified in paragraphs (i)(1) and (i)(2) of this AD 
in accordance with the Accomplishment Instructions of the service 
bulletin.
    (1) Do a detailed inspection for chafed wiring of the wing fuel 
boost pumps, and, before further flight thereafter, do all 
applicable corrective and other specified actions.
    (2) Modify the wing fuel boost pumps.

    Note 1: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

    (j) Before further flight after the inspection and modification 
required by paragraph (i) of this AD, remove the AFM temporary 
change and placard required by paragraphs (g) and (h) of this AD.

Reporting Clarification

    (k) Although the service bulletin specifies to submit certain 
information to the manufacturer, this AD does not include that 
requirement.

Alternative Methods of Compliance (AMOCs)

    (l)(1) The Manager, Wichita Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested in 
accordance with the procedures found in 14 CFR 39.19.
    (2) Before using any AMOC approved in accordance with 14 CFR 
39.19 on any airplane to which the AMOC applies, notify the 
appropriate principal inspector in the FAA Flight Standards 
Certificate Holding District Office.
