ACTION: Final rule; request for
comments.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Cessna Model 750 airplanes. The AD
requires repetitive inspections for
clearance and chafing of an auxiliary
power unit (APU) fuel tube assembly in
the tail cone area of the airplane, and
corrective actions if necessary. For
certain airplanes, this AD also requires
replacing the APU fuel line. This AD is
prompted by reports of chafed APU fuel
tubes leaking into the tail cone area due
to interference between the fuel tube
assembly and elevator flight control
cables, hydraulic lines, and hightemperature bleed air couplings. We are
issuing this AD to detect and correct
this interference, which could result in
chafing, fuel leaking into an area where
ignition sources are present, and
possible fire in an area without fire
detection or extinguishing provisions.
DATES: Effective May 10, 2005.
The incorporation by reference of
certain publications listed in the AD is
approved by the Director of the Federal
Register as of May 10, 2005.

We have
received reports of severely chafed
auxiliary power unit (APU) fuel tubes
found during routine maintenance on
Cessna Model 750 airplanes. The APU
fuel tubes were leaking into the tail cone
area of the airplane due to chafing from
interference between the fuel tube and
elevator flight control cables, hydraulic
lines, and high temperature bleed air
couplings. This condition, if not
corrected, could result in fuel leaking
into an area where ignition sources are
present, and consequent fire in an area
without fire detection or extinguishing
provisions.

Federal Register / Vol. 70, No. 78 / Monday, April 25, 2005 / Rules and Regulations
Relevant Service Information
We have reviewed Cessna Alert
Service Letter (ASL) ASL750–49–09,
Revision 2, dated March 10, 2005. The
ASL describes procedures for repetitive
inspections to verify the clearance and
detect chafing of one of the APU fuel
tube assemblies in the tail cone area of
the airplanes. The inspections
specifically are intended to detect and
correct possible interference between
the APU fuel tube and elevator flight
control cables, hydraulic lines, and
high-temperature bleed air couplings.
Corrective actions include the
following:
CORRECTIVE ACTIONS
Inspect—
And—
If you find—
For chafing damage on the APU fuel tube assembly.
Replace the APU fuel tube assembly with
new parts.
For chafing damage on the elevator control cables.
Replace the elevator control cable with new
parts.
Blend out the damage .....................................
The clearance of the APU fuel tube assembly ..
Adjust routing of the APU fuel tube assembly
Any lengthwise scratch.
Other nicks/scratches, and chafing and dents
that exceed certain limits.
Chafing with visible wire braids and broken
wires.
Chafing with visible wire braids and no broken
wires.
Chafing with no visible wire braids.
Inadequate clearance between APU fuel tube
assembly and—
• elevator cables.
• high-temperature bleed air lines.
• electrical wiring.
• airframe structure.
• hydraulic lines.
The ASL specifies sending a report of
the inspection results to the
manufacturer.
For certain airplanes, the ASL also
specifies replacing, with new parts, and
relocating the APU fuel tube in the tail
cone area of the airplane. Those
procedures are described in Cessna
Service Bulletin SB750–49–05, Revision
1, dated January 17, 2000. The ASL
specifies installing the new APU fuel
tube before the initial inspection
specified in the ASL.
FAA’s Determination and Requirements
of This AD
The unsafe condition described
previously is likely to exist or develop
on other airplanes of the same type
design. Therefore, we are issuing this
AD to prevent fuel from leaking into an
area where ignition sources are present,
which could result in a fire in an area
without fire detection or extinguishing
provisions. This AD requires
accomplishing the actions specified in
the service information described
previously. This AD also requires
reporting the inspection results to
Cessna.
Interim Action
We consider this AD interim action.
The manufacturer is currently
developing a modification that may
terminate the repetitive inspections
required by this AD action. Once this
modification is developed, approved,
and available, we may consider
additional rulemaking.

FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD; therefore, providing notice and
opportunity for public comment before
the AD is issued is impracticable, and
good cause exists to make this AD
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves
requirements that affect flight safety and
was not preceded by notice and an
opportunity for public comment;
however, we invite you to submit any
relevant written data, views, or
arguments regarding this AD. Send your

economic, environmental, and energy
aspects of the AD. We will consider all
comments received by the closing date
and may amend the AD in light of those
comments.
We will post all comments we
receive, without change, to https://
dms.dot.gov, including any personal
information you provide. We will also
post a report summarizing each
substantive verbal contact with FAA
personnel concerning this AD. Using the

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.

SUPPLEMENTARY INFORMATION: We have received reports of severely chafed
auxiliary power unit (APU) fuel tubes found during routine maintenance
on Cessna Model 750 airplanes. The APU fuel tubes were leaking into the
tail cone area of the airplane due to chafing from interference between
the fuel tube and elevator flight control cables, hydraulic lines, and
high temperature bleed air couplings. This condition, if not corrected,
could result in fuel leaking into an area where ignition sources are
present, and consequent fire in an area without fire detection or
extinguishing provisions.

Relevant Service Information
We have reviewed Cessna Alert Service Letter (ASL) ASL750-49-09,
Revision 2, dated March 10, 2005. The ASL describes procedures for
repetitive inspections to verify the clearance and detect chafing of
one of the APU fuel tube assemblies in the tail cone area of the
airplanes. The inspections specifically are intended to detect and
correct possible interference between the APU fuel tube and elevator
flight control cables, hydraulic lines, and high-temperature bleed air
couplings. Corrective actions include the following:

------------------------------------------------------------------------
The ASL specifies sending a report of the inspection results to the
manufacturer.
For certain airplanes, the ASL also specifies replacing, with new
parts, and relocating the APU fuel tube in the tail cone area of the
airplane. Those procedures are described in Cessna Service Bulletin
SB750-49-05, Revision 1, dated January 17, 2000. The ASL specifies
installing the new APU fuel tube before the initial inspection
specified in the ASL.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other airplanes of the same type design. Therefore, we are
issuing this AD to prevent fuel from leaking into an area where
ignition sources are present, which could result in a fire in an area
without fire detection or extinguishing provisions. This AD requires
accomplishing the actions specified in the service information
described previously. This AD also requires reporting the inspection
results to Cessna.
Interim Action
We consider this AD interim action. The manufacturer is currently
developing a modification that may terminate the repetitive inspections
required by this AD action. Once this modification is developed,
approved, and available, we may consider additional rulemaking.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD; therefore, providing notice and opportunity for public comment
before the AD is issued is impracticable, and good cause exists to make
this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for

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.
[[Page 21141]]
For the reasons discussed above, I certify that the regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2005-09-01 Cessna Aircraft Company: Amendment 39-14069. Docket No.
FAA-2005-21026; Directorate Identifier 2005-NM-069-AD.
Effective Date
(a) This AD becomes effective May 10, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Cessna Model 750 airplanes, certificated
in any category, serial numbers-0001 through-0240 inclusive.
Unsafe Condition
(d) This AD was prompted by reports of chafed auxiliary power
unit (APU) fuel tubes leaking into the tail cone area of the
airplane due to interference between the APU fuel tube assembly and
elevator flight control cables, hydraulic lines, and high
temperature bleed air couplings. The FAA is issuing this AD to
detect and correct this interference, which could result in chafing,
leaking into an area where ignition sources are present, and
possible fire in an area without fire detection or extinguishing
provisions.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspections
(f) For all airplanes: Within 25 flight hours or 48 days,
whichever occurs first after the effective date of this AD, do a
detailed inspection to verify the clearance and detect chafing of
one of the APU fuel tube assemblies in the tail cone area of the
airplane due to interference between the APU fuel tube and elevator
flight control cables, hydraulic lines, and high temperature bleed
air couplings. Do the actions in accordance with the Accomplishment
Instructions of Cessna Alert Service Letter (ASL) ASL750-49-09,
Revision 2, dated March 10, 2005. Do applicable corrective actions
before further flight in accordance with the ASL. Repeat the
inspection thereafter at the earlier of the times specified in
paragraphs (f)(1) and (f)(2) of this AD.
(1) At intervals not to exceed 250 flight hours or 3 months,
whichever occurs first.
(2) Before further flight after access to the inspection area
for any other inspection or maintenance.
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.''
APU Replacement
(g) For airplanes having serial numbers -0001 through -0031
inclusive and -0033 through -0107 inclusive: Before the first
inspection required by paragraph (f) of this AD, replace the APU
fuel tube in the tail cone area of the airplane, in accordance with
Cessna Service Bulletin SB750-49-05, Revision 1, dated January 17,
2000. The replacement APU fuel tube must be a new APU fuel tube
having part number 6756605-23.
Report
(h) At the applicable time specified in paragraph (h)(1) or
(h)(2) of this AD, report the results (both positive and negative
findings) of the initial inspection required by paragraph (f) of
this AD, in accordance with Cessna ASL ASL750-49-09, Revision 2,
dated March 10, 2005. Information collection requirements contained
in this AD have been approved by the Office of Management and Budget
(OMB) under the provisions of the Paperwork Reduction Act of 1980
(44 U.S.C. 3501 et seq.) and have been assigned OMB Control Number
2120-0056.
(1) If the inspection was done after the effective date of this
AD: Submit the report within 30 days after the inspection.
(2) If the inspection was done before the effective date of this
AD: Submit the report within 30 days after the effective date of
this AD.
Alternative Methods of Compliance (AMOCs)
(i) 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.
