Amendment 39-15620; AD 2008-16-02]
RIN 2120-AA64

 
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:

------------------------------------------------------------------------
                                                         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 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.
