Airworthiness Directives; Hawker Beechcraft Corporation Model 390
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Hawker Beechcraft Corporation Model 390 airplanes. This AD requires 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 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 issuing this AD to correct potentially inadequate
stall warning with loss of stick pusher function.

DATES: This AD becomes effective on September 3, 2008.
On September 3, 2008, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:

Discussion

On March 19, 2008, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain Hawker Beechcraft Corporation Model 390
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on March 25, 2008 (73 FR 15678).
The NPRM proposed to 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.

Comments

We provided the public the opportunity to participate in developing
this AD. We received no comments on the proposal or on the
determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for minor editorial corrections. We have determined that these
minor corrections:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Costs of Compliance

We estimate that this AD affects 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.
------------------------------------------------------------------------

We estimate that the post-flight residual heat check requires about
3 minutes to do. We estimate the following costs to do 10 of the 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 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:

We estimate the following costs to do any 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 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 = $18,600............ $18,760
$160.
------------------------------------------------------------------------

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,

[[Page 44144]]

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 AD.

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 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 summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2008-0353; Directorate Identifier 2007-CE-101-AD'' in your
request.
