Airworthiness Directives; Cessna Aircraft Company Models 441 and 
F406 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule

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

SUMMARY: This amendment revises Airworthiness Directive (AD) 2003-09-
09, which applies to certain Cessna Aircraft Company (Cessna) Models 
441 and F406 airplanes. AD 2003-09-09 currently requires repetitively 
inspecting the fuel boost pump wiring inside and outside the boost pump 
reservoir and repair or replacement of the wiring as necessary. AD 
2003-09-09 also requires eventual installation of an improved design 
wire harness and fuel boost pump as terminating action for the 
repetitive inspections. The way the compliance time is currently 
written puts certain airplane owners/operators in non-compliance with 
the AD. Also, the terminating action for the repetitive inspections did 
not provide the option of installing the protective sleeving 
modification for boost pump lead wires. This document clarifies and 
corrects the compliance time and provides the option of installing the 
protective sleeving modification for boost pump lead wires. The actions 
specified by this AD are intended to detect, correct, and prevent 
chafing and/or arcing of the fuel boost pump wiring, which could result 
in arcing within the wing fuel storage system. This condition could 
lead to ignition of explosive vapor within the fuel storage system.

DATES: This AD becomes effective on January 22, 2004.
    The Director of the Federal Register previously approved the 
incorporation by reference of certain publications listed in the 
regulations as of June 24, 2003 (68 FR 23186, May 1, 2003).

SUPPLEMENTARY INFORMATION:

Discussion

What Prior AD Action Did FAA Take on This Subject?

    We issued AD 2003-09-09, Amendment 39-13138 (68 FR 23186, May 1, 
2003), in order to detect, correct, and prevent chafing and/or arcing 
of the fuel boost pump wiring on certain Cessna Models 441 and F406 
airplanes. This AD currently requires repetitively inspecting the fuel 
boost pump wiring inside and outside the boost pump reservoir and 
repair or replacement of the wiring as necessary, and requires eventual 
installation of an improved design wire harness and fuel boost pump as 
terminating action for the repetitive inspections. AD 2003-09-09 
superseded AD 2002-09-13, which required only a one-time inspection and 
repair or replacement of the wiring as necessary on Model 441 
airplanes.

What Has Happened To Necessitate Further AD Action?

    We established the compliance time of AD 2003-09-09 to coincide 
with the initial inspection of AD 2002-09-13. The compliance time is 
currently written as:

    ``Initially at whichever occurs first, unless already 
accomplished: Within the next 25 hours time-in-service (TIS) or 60 
days after May 31, 2002 (the effective date of AD 2002-09-13): 
Repetitively thereafter at intervals not to exceed 200 hours TIS.''

    The FAA has found that there are a few airplanes that have already 
accumulated more than 200 hours TIS after the last inspection required 
by AD-2002-09-13. The way the compliance time is currently written puts 
these airplane owners/operators in non-compliance with the AD.
    This was not FAA's intent. Our intent was to give every owner/
operator of the affected airplanes a grace period for accomplishing the 
AD without jeopardizing the safety of these airplanes.
    The option of installing the protective sleeving modification for 
boost pump lead wires is included in the service information. However, 
AD 2003-09-09 did not address this option. It is FAA's intent that the 
AD provide this option for the affected airplanes.
    Consequently, FAA sees a need to clarify and correct AD 2003-09-09 
to assure that every owner/operator of the affected airplanes is able 
to comply with the AD action.

Correction of Publication

What Is the Purpose of This Document?

    This document clarifies the intent of the compliance time of AD 
2003-09-09, adds the option of installing the protective sleeving 
modification, and adds the amendment to section 39.13 of the Federal 
Aviation Regulations (14 CFR 39.13).

Is It Necessary To Seek Public Input?

    Since this action only clarifies the intent of the compliance time 
and provides a compliance option, it has no adverse economic impact and 
imposes no additional burden on any person than would have been 
necessary to comply with AD 2003-09-09. Therefore, FAA has determined 
that prior notice and opportunity for public comment are unnecessary.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the Federal Aviation Administration amends part 39 of the Federal 
Aviation Regulations (14 CFR part 39) as follows:

 specified in paragraphs
 (d)(4) and (d)(5) of this
 AD.
------------------------------------------------------------------------

    (e) Can I comply with this AD in any other way?
    (1) You may use an alternative method of compliance or adjust 
the compliance time if:
    (i) Your alternative method of compliance provides an equivalent 
level of safety; and
    (ii) The Manager, Wichita Aircraft Certification Office (ACO), 
approves your alternative. Submit your request through an FAA 
Principal Maintenance Inspector, who may add comments and then send 
it to the Manager, Wichita ACO.
    (2) Alternative methods of compliance approved in accordance 
with AD 2003-09-09 or AD 2002-09-13 are approved as alternative 
methods of compliance for all inspection requirements of this AD. 
Regardless, you still must comply with the replacement requirements 
of this AD.

    Note: This AD applies to each airplane identified in paragraph 
(a) of this AD, regardless of whether it has been modified, altered, 
or repaired in the area subject to the requirements of this AD. For 
airplanes that have been modified, altered, or repaired so that the 
performance of the requirements of this AD is affected, the owner/
operator must request approval for an alternative method of 
compliance in accordance with paragraph (e) of this AD. The request 
should include an assessment of the effect of the modification, 
alteration, or repair on the unsafe condition addressed by this AD; 
and, if you have not eliminated the unsafe condition, specific 
actions you propose to address it.

    (f) Where can I get information about any already-approved 
alternative methods of compliance? Contact Robert Adamson, Aerospace 
Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport 
Road, Room 100, Wichita, Kansas 67209; telephone: 316-946-4145; 
facsimile: 316-946-4107.
    (g) What if I need to fly the airplane to another location to 
comply with this AD? The FAA can issue a special flight permit under 
Sec. Sec.  21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate your airplane to a location where 
you can accomplish the requirements of this AD.
    (h) Are any service bulletins incorporated into this AD by 
reference? Actions required by this AD must be done following Cessna 
Conquest Service Bulletin No.: CQB02-1, Revision 2, dated October 7, 
2002; and Reims Cessna Caravan Service Bulletin No.: CAB02-8, dated 
June 3, 2002. The Director of the Federal Register previously 
approved this incorporation by reference under 5 U.S.C. 552(a) and 1 
CFR part 51 on June 24, 2003 (68 FR 23186, May 1, 2003). You may get 
copies from Cessna Aircraft Company, Product Support, P.O. Box 7706, 
Wichita, Kansas 67277; telephone: (316) 517-5800; facsimile: (316) 
942-9006. You may view copies at the FAA, Central Region, Office of 
the Regional Counsel, 901 Locust, Room 506, Kansas City, Missouri, 
or at the Office of the Federal Register, 800 North Capitol Street, 
NW., suite 700, Washington, DC.
    (i) Does this AD action affect any existing AD actions? This 
amendment revises AD 2002-09-13, Amendment 39-12746.
    (j) When does this amendment become effective? This amendment 
becomes effective on January 22, 2004.

    Issued in Kansas City, Missouri, on January 5, 2004.
