AGENCY:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for certain
Hawker Beechcraft Corporation Model
390 airplanes. This proposed AD would
require you to repetitively do a postflight check (owner/operator holding at
least a private pilot certificate checking
for residual heat in the angle-of-attack
(AOA) probes or an appropriately-rated
mechanic doing a maintenance manual
operational test of the heat of the AOA
probes) after every flight and replace or
modify (upload software) the stall
warning AOA transmitters. This
proposed AD results from reports of the
potential for unannunciated loss of the
heating function in the left-hand (LH)
and right-hand (RH) stall warning AOA
transmitters of Model 390 airplanes. We
are proposing this AD to correct
potentially inadequate stall warning
with loss of stick pusher function.
DATES: We must receive comments on
this proposed AD by May 27, 2008.

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written
relevant data, views, or arguments
regarding this proposed AD. Send your
comments to an address listed under the
ADDRESSES section. Include the docket
number, ‘‘FAA–2008–0353; Directorate
Identifier 2007–CE–101–AD’’ at the
beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
the proposed AD. We will consider all
comments received by the closing date
and may amend the proposed AD in
light of those comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
concerning this proposed AD.
Discussion
We have received reports of the
potential for unannunciated loss of the
heating function in the LH/RH stall
warning AOA transmitters of Model 390
airplanes. The current AOA transmitter
software may not always annunciate
certain failure modes of the probe or
case heating circuits.
This condition, if not corrected, could
result in potentially inadequate stall
warning with loss of stick pusher
function.
Relevant Service Information
We have reviewed Hawker Beechcraft
Mandatory Service Bulletin No. SB 27–
3787, issued: May 2007; and Raytheon
Aircraft Company Temporary Change to
the FAA Approved Airplane Flight
Manual P/N 390–590001–0003CTC7,
issued: March 15, 2007. The service
information describes procedures for the
replacement/modification of the stall
warning AOA transmitters. The airplane
flight manual (AFM) describes
procedures for doing a post-flight check.
This post-flight check can be either the
pilot checking for residual heat in the
AOA probes as part of the shutdown
procedure or, alternatively, having the
AOA probe heat operational test
maintenance manual procedure done by
an appropriately-rated mechanic.
FAA’s Determination and Requirements
of the Proposed AD
We are proposing this AD because we
evaluated all information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This proposed AD would
require a repetitive post-flight check for
residual heat in the AOA probes or a
maintenance manual operational test of
the heat of the AOA probes after every
flight and replace or modify (upload
software) the stall warning AOA
transmitters. Replacement or
modification (upload software) of the
stall warning AOA transmitters
terminates the repetitive requirement to
do the post-flight action.
Costs of Compliance
We estimate that this proposed AD
would affect 152 airplanes in the U.S.
registry.
We estimate the following costs to
incorporate and remove the temporary
change to the AFM.
Labor cost
Parts cost
Total cost per
airplane
0.5 work-hour × $80 per hour = $40 ............................................................................

Federal Register / Vol. 73, No. 58 / Tuesday, March 25, 2008 / Proposed Rules
We estimate that the proposed postflight residual heat check requires about
3 minutes to do. We estimate the
following costs to do 10 of the proposed
post-flight residual heat checks. We
have no way of determining the number
of airplanes that would have this postflight residual heat check, or how many
times this will need to be performed
before the terminating action is done:

We estimate the following costs to do
the proposed maintenance manual
operational test of the heat of the AOA
probes. We have no way of determining
the number of airplanes that would have
this operational test, or how many times
this will need to be performed before
the terminating action is done:
Labor cost
Parts cost
Total cost per
airplane
0.5 work-hour × $80 per hour = $40 ............................................................................

We estimate the following costs to do
any proposed upload of software to the
AOA transmitters. We have no way of

Total cost per
airplane
4 work-hours × $80 per hour = $320 ...........................................................................

airplanes that would have this
replacement:

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
proposed AD would not have federalism
implications under Executive Order
VerDate Aug<31>2005
16:26 Mar 24, 2008
Jkt 214001
13132. This proposed AD would 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 the proposed 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 proposed AD and placed it in the
AD docket.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2008–0249,
dated September 24, 2007 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
During planned maintenance visit on one
A320 aircraft, a cross connection of the fire
extinguishing circuit system was identified.
In case of fire, this cross connection will
activate (discharge) the wrong forward or aft
cargo compartment fire extinguisher bottle.
Failure to activate the correct bottle when
required is classified as potentially
catastrophic.
PO 00000
Frm 00004
Fmt 4702
Sfmt 4702
15681
For the reasons described above, this AD
requires a one-time inspection and check of
the cargo firing circuit continuity to confirm
the correct connection of the dedicated wires
between the discharge pushbutton switches
and the relevant cargo bottle.
Corrective action includes modifying
the wiring connection on plug 1505VC–
A. You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
Airbus has issued Service Bulletin
A320–26A1068, Revision 01, dated July
19, 2007. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
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
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are
highlighted in a NOTE within the
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 679 products of U.S.
registry. We also estimate that it would
take about 6 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
$325,920, or $480 per product.

-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Hawker Beechcraft Corporation Model 390 airplanes. This
proposed AD would require you to repetitively do a post-flight check
(owner/operator holding at least a private pilot certificate checking
for residual heat in the angle-of-attack (AOA) probes or an
appropriately-rated mechanic doing a maintenance manual operational
test of the heat of the AOA probes) after every flight and replace or
modify (upload software) the stall warning AOA transmitters. This
proposed AD results from reports of the potential for unannunciated
loss of the heating function in the left-hand (LH) and right-hand (RH)
stall warning AOA transmitters of Model 390 airplanes. We are proposing
this AD to correct potentially inadequate stall warning with loss of
stick pusher function.

Discussion
We have received reports of the potential for unannunciated loss of
the heating function in the LH/RH stall warning AOA transmitters of
Model 390 airplanes. The current AOA transmitter software may not
always annunciate certain failure modes of the probe or case heating
circuits.
This condition, if not corrected, could result in potentially
inadequate stall warning with loss of stick pusher function.
Relevant Service Information
We have reviewed Hawker Beechcraft Mandatory Service Bulletin No.
SB 27-3787, issued: May 2007; and Raytheon Aircraft Company Temporary
Change to the FAA Approved Airplane Flight Manual P/N 390-590001-
0003CTC7, issued: March 15, 2007. The service information describes
procedures for the replacement/modification of the stall warning AOA
transmitters. The airplane flight manual (AFM) describes procedures for
doing a post-flight check. This post-flight check can be either the
pilot checking for residual heat in the AOA probes as part of the
shutdown procedure or, alternatively, having the AOA probe heat
operational test maintenance manual procedure done by an appropriately-
rated mechanic.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would require a repetitive post-flight check for residual heat in the
AOA probes or a maintenance manual operational test of the heat of the
AOA probes after every flight and replace or modify (upload software)
the stall warning AOA transmitters. Replacement or modification (upload
software) of the stall warning AOA transmitters terminates the
repetitive requirement to do the post-flight action.
Costs of Compliance
We estimate that this proposed AD would affect 152 airplanes in the
U.S. registry.
We estimate the following costs to incorporate and remove the
temporary change to the AFM.
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
0.5 work-hour x $80 per hour = Not Applicable...... $40
$40.
------------------------------------------------------------------------
[[Page 15679]]
We estimate that the proposed post-flight residual heat check
requires about 3 minutes to do. We estimate the following costs to do
10 of the proposed post-flight residual heat checks. We have no way of
determining the number of airplanes that would have this post-flight
residual heat check, or how many times this will need to be performed
before the terminating action is done:
------------------------------------------------------------------------
Labor cost to do 10 post-flight Total cost per
residual heat checks Parts cost airplane
------------------------------------------------------------------------
0.5 work-hour x $80 per hour = Not Applicable...... $40
$40.
------------------------------------------------------------------------
We estimate the following costs to do the proposed maintenance
manual operational test of the heat of the AOA probes. We have no way
of determining the number of airplanes that would have this operational
test, or how many times this will need to be performed before the
terminating action is done:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
0.5 work-hour x $80 per hour = Not Applicable...... $40
$40.
------------------------------------------------------------------------
We estimate the following costs to do any proposed upload of
software to the AOA transmitters. We have no way of determining the
number of airplanes that would have this modification:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
4 work-hours x $80 per hour = Not Applicable...... $320
$320.
------------------------------------------------------------------------
We estimate the following costs to do any proposed replacement of 2
stall warning AOA transmitters. We have no way of determining the
number of airplanes that would have this replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
2 work-hours x $80 per hour = $160.... $18,600 $18,760
------------------------------------------------------------------------
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
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 proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.
