The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2008–1312; Directorate Identifier 2008–CE–065–AD] RIN 2120–AA64 Airworthiness Directives; Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D Airplanes sroberts on DSKD5P82C1PROD with PROPOSALS AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (NPRM); Reopening of the comment period. SUMMARY: We are revising an earlier proposed airworthiness directive (AD) that applies to certain Hawker Beechcraft Corporation Models 1900, 1900C, and 1900D airplanes. The earlier NPRM would have required a one-time visual inspection and repetitive ultrasonic inspections of the left and right main landing gear (MLG) actuators for leaking and/or cracks with replacement of the actuator if leaking and/or cracks are found. The earlier NPRM resulted from reports of leaking and cracked actuators. This proposed AD would require the same actions as the earlier NPRM. Since the earlier NPRM, we have identified a MLG overhauled actuator part number and a MLG actuator approved by parts manufacturer approval (PMA) by identicality. We propose to expand the applicability to include airplanes equipped with these additional part numbers. Because this imposes an additional burden over that proposed in the earlier NPRM, we are reopening the comment period to allow the public the chance to comment on these additional MLG actuators. DATES: We must receive comments on this proposed AD by September 30, 2009.

We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD. Discussion On December 8, 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 Models 1900, 1900C, and 1900D airplanes. This proposal was published PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 in the Federal Register as a notice of proposed rulemaking (NPRM) on December 15, 2008 (73 FR 75977). The NPRM proposed to require a one-time visual inspection and repetitive ultrasonic inspections of the left and right main landing gear (MLG) actuators for leaking and/or cracks with replacement of the actuator if leaking and/or cracks are found. Comments We provided the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and FAA’s response to each comment: Comment Issue No. 1: Report to TypeCertificate (TC) Holder by E-Mail Wayne R. Modny and Hawker Beechcraft Corporation request the option of using e-mail to send the report required in this AD. The FAA agrees with allowing owners/operators to comply with the reporting requirement by e-mail. However, we have changed the proposed AD action and no longer require owners/operators to report to the TC holder. We retained the proposed reporting requirement to the FAA and provided an e-mail address for complying with that proposed AD action. Comment Issue No. 2: Replacement of Actuator With Other Part Number (P/N) Actuators Gulfstream International Airlines requests that we not limit replacement of the MLG actuator to P/N 114– 380041–17 because other FAA-approved P/Ns (P/N 114–380041–7 or –9) could be used as terminating action. The commenter states that terminating action should consist of replacing the affected actuator with an actuator of a P/N listed in the Hawker Beechcraft illustrated parts catalog other than P/N 114–380041–15. The FAA agrees. Our intent was to not allow installation of P/Ns 114–380041– 11 and 114–380041–13 and only allow installation of P/N 114–380041–15 (or P/N 114–380041–15OVH) if the end caps were new or had been inspected per paragraph (e)(1), (e)(2), or (e)(3) of this proposed AD. Installation of other FAA-approved actuators as terminating action is acceptable. The service bulletin calls out replacement parts that are readily available. The P/N 114– E:\FR\FM\31AUP1.SGM 31AUP1 44774 Federal Register / Vol. 74, No. 167 / Monday, August 31, 2009 / Proposed Rules 380041–17 is the latest part number available that is not affected by the inspections in this proposed AD. The earlier P/N 114–380041–7 or P/N 114– 380041–9 actuator may be used as terminating action in place of the P/N 114–380041–17; however, parts availability is not guaranteed. We will change the proposed AD action to allow installation of other FAA-approved actuators in paragraph (e)(4) of this AD. sroberts on DSKD5P82C1PROD with PROPOSALS Comment Issue No. 3: Ultrasonic Inspections Hawker Beechcraft Corporation requests that we remove the words ‘‘FAA-approved equivalent P/N’’ from the replacement parts language of the AD. Using ‘‘FAA-approved equivalent P/N’’ for replacement parts could be misintrepeted to mean that 114–380041 actuators manufactured by Airtight or Tactair may also be required to do the ultrasonic inspections. The ultrasonic inspection defined in the Hawker Beechcraft Service Bulletin 32–3870, dated April 2008, is approved only for MLG actuators P/N 114–380041–11, P/N 114–380041–13, and P/N 114– 380041–15 manufactured by Triumph Actuation Systems (previously manufactured by Frisby). The FAA partially agrees. We agree that Hawker Beechcraft Service Bulletin 32–3870, dated April 2008, should not be used to do ultrasonic inspections on MLG actuators produced by another manufacturer. However, we disagree that the words ‘‘FAA-approved equivalent P/N’’ should be removed from the applicability or replacement parts language. Our research shows Frisby Airborne Hydraulic, Inc. (Frisby) has PMA approval by identicality for their P/N 1FA10043–3 actuator as a replacement for Hawker Beechcraft P/N 114–380041–15. Therefore by including ‘‘FAA-approved equivalent P/N’’ in both the applicability and replacement parts language of this proposed AD, P/N 1FA10043–3 and any other actuator that is PMA approved by identicality can be used as a replacement part. They will also be subject to the inspection requirement of the AD, but the Hawker Beechcraft service bulletin cannot be used. We will change the proposed AD action by referencing Hawker Beechcraft Service Bulletin 32–3870, dated April 2008, to do the visual and ultrasonic inspections only for P/N 114–380041– 11, P/N 114–380041–13, and P/N 114– 380041–15 (or P/N 114–380041– 15OVH). For FAA-approved equivalent part numbers, the owner/operator must contact the PMA holder to obtain FAA- VerDate Nov<24>2008 16:24 Aug 28, 2009 Jkt 217001 approved inspection instructions to do the visual and ultrasonic inspections. Comment Issue No. 4: P/Ns for Terminating Action Hawker Beechcraft Corporation requests that we change the words of the AD to make it clear that only MLG actuators P/N 114–380041–11, P/N 114– 380041–13, and P/N 114–380041–15 are affected by the AD and that only P/N 114–380041–17 terminates the requirements of the AD. The Applicability is for MLG actuators P/N 114–380041–11, P/N 114–380041–13, and P/N 114–380041–15, but wording in some areas of the AD imply all P/N 114– 380041 actuators. The FAA disagrees. The P/N 114– 380041–17 is the most current part number available that is not affected by the inspections proposed in this proposed AD. However, installation of other FAA-approved actuators as terminating action is acceptable, such as P/N 114–380041–7 or P/N 114–380041– 9. The wording ‘‘FAA-approved equivalent P/N’’ applies to actuators that are FAA-approved by identicality through the PMA process. Our research shows Frisby has PMA approval for their P/N 1FA10043–3 actuator as a replacement for Hawker Beechcraft P/N 114–380041–15. Therefore by including ‘‘FAA-approved equivalent P/N’’ in the replacement parts language of this proposed AD, P/N 1FA10043–3 can be used as a direct replacement for Hawker Beechcraft P/N 114–380041–15. Since P/N 1FA10043–3 is a PMA part through identicality for P/N 114–380041–15, the AD should also apply to that P/N and any other parts that may have PMA through identicality to P/N 114– 380041–11, P/N 114–380041–13, and P/ N 114–380041–15. We will change the proposed AD action to add the language ‘‘FAAapproved equivalent P/N’’ for P/N 114– 380041–11, P/N 114–380041–13, and P/N 114–380041–15 into the Applicability section. We will also add that for the purposes of this AD action the phrase ‘‘or FAA-approved equivalent part number’’ in this AD refers to any PMA part that is approved by identicality to the referenced part. Comment Issue No. 5: Previous Inspections Wayne R. Modny requests that the compliance inspection criteria defined in paragraphs (e)(1) and (e)(2) of the NPRM address previously inspected parts. If the initial 50-hour visual inspection and the initial 600-cycle ultrasonic inspection have been done following Hawker Beechcraft Mandatory Service Bulletin SB 32–3870, dated PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 April 2008, then these initial inspections should not have to be repeated for the AD. The FAA agrees. The language as written in paragraph (e) of this proposed AD, ‘‘you must do the following, unless already done’’ allows for the inspections already done following Hawker Beechcraft Mandatory Service Bulletin SB 32–3870, dated April 2008. We will not change the proposed AD action based on this comment. Comment Issue No. 6: Overhauled Actuators and New End Caps Hawker Beechcraft Corporation requests that we add language to the actions of this AD to allow for overhauled actuators that have records that prove an internal fluorescent penetrant inspection had been done and for actuators that have records that prove the end caps are new. The FAA agrees. For MLG overhauled actuators that have records that prove an internal fluorescent penetrant inspection has been done and for MLG actuators that have records that prove the end caps are new, we agree that the Hawker Beechcraft Mandatory Service Bulletin SB 32–3870, dated April 2008, makes a compliance time allowance for the initial ultrasonic inspection proposed in this AD. We will change the proposed AD action by adding language that allows compliance time differences for overhauled MLG actuators that have had an internal fluorescent penetrant inspection and for MLG actuators that have new end caps. Comment Issue No. 7: Compliance Time Units Hawker Beechcraft Corporation requests that we remove the NOTE with the conversion formula to determine hours time-in-service (TIS) in lieu of cycles because it is not needed or to add the words ‘‘If the number of cycles is not known’’ at the beginning of the note. The 1900 series fleet tracks cycles, and the landing gear component inspections, specifically, are tracked by cycles. The conversion formula could lead to an interpretation that hours TIS should be used even if the number of cycles is known. The FAA agrees that the note could include language to indicate the formula applies if the number of cycles is not known. However, since an owner/ operator must use the conversion formula if the number of cycles is unknown, we are changing the note to an action statement in this proposed AD. NOTES are for information purposes only and do not include required actions. The proposed actions E:\FR\FM\31AUP1.SGM 31AUP1 44775 Federal Register / Vol. 74, No. 167 / Monday, August 31, 2009 / Proposed Rules in the AD use cycles for the compliance time. We will change the note in the Compliance section of this proposed AD to an action and add the words ‘‘If the number of cycles is not known’’ at the beginning of that paragraph. FAA’s Determination and Requirements of This Proposed AD We have carefully reviewed the available data and determined that the unsafe condition referenced in this document exists or could develop on other products of the same type design; and we should take AD action to correct this unsafe condition. Certain changes described above expand the scope of the earlier NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on the proposed AD. The Supplemental NPRM Since we issued the earlier NPRM, we have expanded the Applicability section to include airplanes equipped with not only part numbers (P/Ns) 114–380041– 11, 114–380041–13, or 114–380041–15 MLG actuators but also airplanes equipped with FAA-approved equivalent P/Ns that have PMA by identicality to those referenced parts. Frisby P/N 1FA10043–3 has PMA by identicality to P/N 114–380041–15; therefore, it is considered an FAAapproved equivalent P/N and the proposed AD applies to airplanes with this part installed. We have also identified an overhauled MLG actuator part number and have included that part number in the Applicability section. This goes beyond the scope of what was originally proposed in the NPRM. Therefore, we are reopening the comment period and allowing the public the chance to comment on these additional actions. Costs of Compliance We estimate that this AD affects 300 airplanes in the U.S. registry. The ultrasonic inspection includes the time allowed for removing and reinstalling the actuator. We estimate the following costs to do the inspections: Total cost per airplane Labor cost Parts cost Visual Inspection: .5 work-hour × $80 per hour = $40 ................................... Ultrasonic Inspection: 6 work-hours × $80 per hour = $480 (If the mechanic does not remove the actuator for the ultrasonic inspection, the labor cost will be less). Not applicable .................................... Not applicable .................................... We estimate the following costs to do any necessary replacements that would be required based on the results of the inspections. We have no way of $40 480 $12,000 144,000 determining the number of airplanes that may need this replacement: Labor cost Parts cost 6 work-hours × $80 per hour = $480 (If the mechanic removes the actuator for the ultrasonic inspection, then the labor cost will be less). Total cost per airplane $4,600 per actuator .................................... Authority for This Rulemaking sroberts on DSKD5P82C1PROD with PROPOSALS Total cost on U.S. operators 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 VerDate Nov<24>2008 16:24 Aug 28, 2009 Jkt 217001 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. $5,080 received, and other information on the Internet at http://dms.dot.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Applicability (c) This AD applies to the airplane models and serial numbers listed below that are certificated in any category and equipped with a Hawker Beechcraft part number (P/N) 114–380041–11 (or FAA-approved equivalent P/N), 114–380041–13 (or FAA-approved equivalent P/N), 114–380041–15 (or FAAapproved equivalent P/N), or 114–380041– 15OVH main landing gear (MLG) actuator. For the purposes of this AD action the phrase ‘‘or FAA-approved equivalent part number’’ in this AD refers to any PMA part that is approved by identicality to the referenced part. Frisby Airborne Hydraulic, Inc. (Frisby) P/N 1FA10043–3 has parts manufacturer approval (PMA) by identicality to P/N 114– 380041–15; therefore, it is considered an FAA-approved equivalent P/N and the AD applies to airplanes with this part installed.

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: The manufacturer has advised of receiving a report of looseness of the drive arm of the mechanical elevator trim tab, found during an annual inspection. This kind of damage is likely caused by penetrated humidity over the years. If left uncorrected, this condition could lead to the separation of the drive arm which could result in flutter of the elevator and possible loss of control of the aircraft. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by October 15, 2009.

Airworthiness Directives; Hawker Beechcraft Corporation Models 
1900, 1900C, and 1900D Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); Reopening of 
the comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) that applies to certain Hawker Beechcraft Corporation Models 1900, 
1900C, and 1900D airplanes. The earlier NPRM would have required a one-
time visual inspection and repetitive ultrasonic inspections of the 
left and right main landing gear (MLG) actuators for leaking and/or 
cracks with replacement of the actuator if leaking and/or cracks are 
found. The earlier NPRM resulted from reports of leaking and cracked 
actuators. This proposed AD would require the same actions as the 
earlier NPRM. Since the earlier NPRM, we have identified a MLG 
overhauled actuator part number and a MLG actuator approved by parts 
manufacturer approval (PMA) by identicality. We propose to expand the 
applicability to include airplanes equipped with these additional part 
numbers. Because this imposes an additional burden over that proposed 
in the earlier NPRM, we are reopening the comment period to allow the 
public the chance to comment on these additional MLG actuators.

DATES: We must receive comments on this proposed AD by September 30, 
2009.

proposed AD:

Discussion

    On December 8, 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 Models 1900, 
1900C, and 1900D airplanes. This proposal was published in the Federal 
Register as a notice of proposed rulemaking (NPRM) on December 15, 2008 
(73 FR 75977). The NPRM proposed to require a one-time visual 
inspection and repetitive ultrasonic inspections of the left and right 
main landing gear (MLG) actuators for leaking and/or cracks with 
replacement of the actuator if leaking and/or cracks are found.

Comments

    We provided the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and FAA's response to each comment:

Comment Issue No. 1: Report to Type-Certificate (TC) Holder by E-Mail

    Wayne R. Modny and Hawker Beechcraft Corporation request the option 
of using e-mail to send the report required in this AD.
    The FAA agrees with allowing owners/operators to comply with the 
reporting requirement by e-mail. However, we have changed the proposed 
AD action and no longer require owners/operators to report to the TC 
holder. We retained the proposed reporting requirement to the FAA and 
provided an e-mail address for complying with that proposed AD action.

Comment Issue No. 2: Replacement of Actuator With Other Part Number (P/
N) Actuators

    Gulfstream International Airlines requests that we not limit 
replacement of the MLG actuator to P/N 114-380041-17 because other FAA-
approved P/Ns (P/N 114-380041-7 or -9) could be used as terminating 
action. The commenter states that terminating action should consist of 
replacing the affected actuator with an actuator of a P/N listed in the 
Hawker Beechcraft illustrated parts catalog other than P/N 114-380041-
15.
    The FAA agrees. Our intent was to not allow installation of P/Ns 
114-380041-11 and 114-380041-13 and only allow installation of P/N 114-
380041-15 (or P/N 114-380041-15OVH) if the end caps were new or had 
been inspected per paragraph (e)(1), (e)(2), or (e)(3) of this proposed 
AD. Installation of other FAA-approved actuators as terminating action 
is acceptable. The service bulletin calls out replacement parts that 
are readily available. The P/N 114-

[[Page 44774]]

380041-17 is the latest part number available that is not affected by 
the inspections in this proposed AD. The earlier P/N 114-380041-7 or P/
N 114-380041-9 actuator may be used as terminating action in place of 
the P/N 114-380041-17; however, parts availability is not guaranteed.
    We will change the proposed AD action to allow installation of 
other FAA-approved actuators in paragraph (e)(4) of this AD.

Comment Issue No. 3: Ultrasonic Inspections

    Hawker Beechcraft Corporation requests that we remove the words 
``FAA-approved equivalent P/N'' from the replacement parts language of 
the AD. Using ``FAA-approved equivalent P/N'' for replacement parts 
could be misintrepeted to mean that 114-380041 actuators manufactured 
by Airtight or Tactair may also be required to do the ultrasonic 
inspections. The ultrasonic inspection defined in the Hawker Beechcraft 
Service Bulletin 32-3870, dated April 2008, is approved only for MLG 
actuators P/N 114-380041-11, P/N 114-380041-13, and P/N 114-380041-15 
manufactured by Triumph Actuation Systems (previously manufactured by 
Frisby).
    The FAA partially agrees. We agree that Hawker Beechcraft Service 
Bulletin 32-3870, dated April 2008, should not be used to do ultrasonic 
inspections on MLG actuators produced by another manufacturer. However, 
we disagree that the words ``FAA-approved equivalent P/N'' should be 
removed from the applicability or replacement parts language. Our 
research shows Frisby Airborne Hydraulic, Inc. (Frisby) has PMA 
approval by identicality for their P/N 1FA10043-3 actuator as a 
replacement for Hawker Beechcraft P/N 114-380041-15. Therefore by 
including ``FAA-approved equivalent P/N'' in both the applicability and 
replacement parts language of this proposed AD, P/N 1FA10043-3 and any 
other actuator that is PMA approved by identicality can be used as a 
replacement part. They will also be subject to the inspection 
requirement of the AD, but the Hawker Beechcraft service bulletin 
cannot be used.
    We will change the proposed AD action by referencing Hawker 
Beechcraft Service Bulletin 32-3870, dated April 2008, to do the visual 
and ultrasonic inspections only for P/N 114-380041-11, P/N 114-380041-
13, and P/N 114-380041-15 (or P/N 114-380041-15OVH). For FAA-approved 
equivalent part numbers, the owner/operator must contact the PMA holder 
to obtain FAA-approved inspection instructions to do the visual and 
ultrasonic inspections.

Comment Issue No. 4: P/Ns for Terminating Action

    Hawker Beechcraft Corporation requests that we change the words of 
the AD to make it clear that only MLG actuators P/N 114-380041-11, P/N 
114-380041-13, and P/N 114-380041-15 are affected by the AD and that 
only P/N 114-380041-17 terminates the requirements of the AD. The 
Applicability is for MLG actuators P/N 114-380041-11, P/N 114-380041-
13, and P/N 114-380041-15, but wording in some areas of the AD imply 
all P/N 114-380041 actuators.
    The FAA disagrees. The P/N 114-380041-17 is the most current part 
number available that is not affected by the inspections proposed in 
this proposed AD. However, installation of other FAA-approved actuators 
as terminating action is acceptable, such as P/N 114-380041-7 or P/N 
114-380041-9. The wording ``FAA-approved equivalent P/N'' applies to 
actuators that are FAA-approved by identicality through the PMA 
process. Our research shows Frisby has PMA approval for their P/N 
1FA10043-3 actuator as a replacement for Hawker Beechcraft P/N 114-
380041-15. Therefore by including ``FAA-approved equivalent P/N'' in 
the replacement parts language of this proposed AD, P/N 1FA10043-3 can 
be used as a direct replacement for Hawker Beechcraft P/N 114-380041-
15. Since P/N 1FA10043-3 is a PMA part through identicality for P/N 
114-380041-15, the AD should also apply to that P/N and any other parts 
that may have PMA through identicality to P/N 114-380041-11, P/N 114-
380041-13, and P/N 114-380041-15.
    We will change the proposed AD action to add the language ``FAA-
approved equivalent P/N'' for P/N 114-380041-11, P/N 114-380041-13, and 
P/N 114-380041-15 into the Applicability section. We will also add that 
for the purposes of this AD action the phrase ``or FAA-approved 
equivalent part number'' in this AD refers to any PMA part that is 
approved by identicality to the referenced part.

Comment Issue No. 5: Previous Inspections

    Wayne R. Modny requests that the compliance inspection criteria 
defined in paragraphs (e)(1) and (e)(2) of the NPRM address previously 
inspected parts. If the initial 50-hour visual inspection and the 
initial 600-cycle ultrasonic inspection have been done following Hawker 
Beechcraft Mandatory Service Bulletin SB 32-3870, dated April 2008, 
then these initial inspections should not have to be repeated for the 
AD.
    The FAA agrees. The language as written in paragraph (e) of this 
proposed AD, ``you must do the following, unless already done'' allows 
for the inspections already done following Hawker Beechcraft Mandatory 
Service Bulletin SB 32-3870, dated April 2008.
    We will not change the proposed AD action based on this comment.

Comment Issue No. 6: Overhauled Actuators and New End Caps

    Hawker Beechcraft Corporation requests that we add language to the 
actions of this AD to allow for overhauled actuators that have records 
that prove an internal fluorescent penetrant inspection had been done 
and for actuators that have records that prove the end caps are new.
    The FAA agrees. For MLG overhauled actuators that have records that 
prove an internal fluorescent penetrant inspection has been done and 
for MLG actuators that have records that prove the end caps are new, we 
agree that the Hawker Beechcraft Mandatory Service Bulletin SB 32-3870, 
dated April 2008, makes a compliance time allowance for the initial 
ultrasonic inspection proposed in this AD.
    We will change the proposed AD action by adding language that 
allows compliance time differences for overhauled MLG actuators that 
have had an internal fluorescent penetrant inspection and for MLG 
actuators that have new end caps.

Comment Issue No. 7: Compliance Time Units

    Hawker Beechcraft Corporation requests that we remove the NOTE with 
the conversion formula to determine hours time-in-service (TIS) in lieu 
of cycles because it is not needed or to add the words ``If the number 
of cycles is not known'' at the beginning of the note. The 1900 series 
fleet tracks cycles, and the landing gear component inspections, 
specifically, are tracked by cycles. The conversion formula could lead 
to an interpretation that hours TIS should be used even if the number 
of cycles is known.
    The FAA agrees that the note could include language to indicate the 
formula applies if the number of cycles is not known. However, since an 
owner/operator must use the conversion formula if the number of cycles 
is unknown, we are changing the note to an action statement in this 
proposed AD. NOTES are for information purposes only and do not include 
required actions. The proposed actions

[[Page 44775]]

in the AD use cycles for the compliance time.
    We will change the note in the Compliance section of this proposed 
AD to an action and add the words ``If the number of cycles is not 
known'' at the beginning of that paragraph.

FAA's Determination and Requirements of This Proposed AD

    We have carefully reviewed the available data and determined that 
the unsafe condition referenced in this document exists or could 
develop on other products of the same type design; and we should take 
AD action to correct this unsafe condition.
    Certain changes described above expand the scope of the earlier 
NPRM. As a result, we have determined that it is necessary to reopen 
the comment period to provide additional opportunity for the public to 
comment on the proposed AD.

The Supplemental NPRM

    Since we issued the earlier NPRM, we have expanded the 
Applicability section to include airplanes equipped with not only part 
numbers (P/Ns) 114-380041-11, 114-380041-13, or 114-380041-15 MLG 
actuators but also airplanes equipped with FAA-approved equivalent P/Ns 
that have PMA by identicality to those referenced parts. Frisby P/N 
1FA10043-3 has PMA by identicality to P/N 114-380041-15; therefore, it 
is considered an FAA-approved equivalent P/N and the proposed AD 
applies to airplanes with this part installed. We have also identified 
an overhauled MLG actuator part number and have included that part 
number in the Applicability section.
    This goes beyond the scope of what was originally proposed in the 
NPRM. Therefore, we are reopening the comment period and allowing the 
public the chance to comment on these additional actions.

Costs of Compliance

    We estimate that this AD affects 300 airplanes in the U.S. 
registry.
    The ultrasonic inspection includes the time allowed for removing 
and reinstalling the actuator. We estimate the following costs to do 
the inspections:

------------------------------------------------------------------------
                                                 Total cost   Total cost
          Labor cost              Parts cost        per        on U.S.
                                                  airplane    operators
------------------------------------------------------------------------
Visual Inspection: .5 work-    Not applicable.          $40      $12,000
 hour x $80 per hour = $40.
Ultrasonic Inspection: 6 work- Not applicable.          480      144,000
 hours x $80 per hour = $480
 (If the mechanic does not
 remove the actuator for the
 ultrasonic inspection, the
 labor cost will be less).
------------------------------------------------------------------------

     We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspections. We have 
no way of determining the number of airplanes that may need this 
replacement:

------------------------------------------------------------------------
                                                              Total cost
             Labor cost                    Parts cost            per
                                                               airplane
------------------------------------------------------------------------
6 work-hours x $80 per hour = $480   $4,600 per actuator...       $5,080
 (If the mechanic removes the
 actuator for the ultrasonic
 inspection, then the labor cost
 will be less).
------------------------------------------------------------------------

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 http://dms.dot.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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

[[Page 44776]]

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Hawker Beechcraft Corporation: Docket No. FAA-2008-1312; Directorate 
Identifier 2008-CE-065-AD.

Comments Due Date

    (a) We must receive comments on this airworthiness directive 
(AD) action by September 30, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to the airplane models and serial numbers 
listed below that are certificated in any category and equipped with 
a Hawker Beechcraft part number (P/N) 114-380041-11 (or FAA-approved 
equivalent P/N), 114-380041-13 (or FAA-approved equivalent P/N), 
114-380041-15 (or FAA-approved equivalent P/N), or 114-380041-15OVH 
main landing gear (MLG) actuator. For the purposes of this AD action 
the phrase ``or FAA-approved equivalent part number'' in this AD 
refers to any PMA part that is approved by identicality to the 
referenced part. Frisby Airborne Hydraulic, Inc. (Frisby) P/N 
1FA10043-3 has parts manufacturer approval (PMA) by identicality to 
P/N 114-380041-15; therefore, it is considered an FAA-approved 
equivalent P/N and the AD applies to airplanes with this part 
installed.

------------------------------------------------------------------------
               Models                             Serial Nos.
------------------------------------------------------------------------

(2) 1900C...........................  UB-1 through UB-74, UC-1 through
                                       UC-174, and UD-1 through UD-6.
(3) 1900D...........................  UE-1 through UE-439.
------------------------------------------------------------------------

Unsafe Condition

    (d) This AD results from reports of leaking and cracked 
actuators. We are issuing this AD to detect and correct leaking and 
cracks in the MLG actuators, which could result in loss of hydraulic 
fluid. This condition could lead to an inability to extend or lock 
down the landing gear, which could result in a gear up landing or a 
gear collapse on landing.

Compliance

    (e) To address this problem, you must do the following, unless 
already done:

    Note: The phrase ``or FAA-approved equivalent part number'' in 
this AD refers to any PMA part that is approved by identicality to 
the referenced part.
