Airworthiness Directives; Short Brothers PLC Model SD3 Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
that applies to the products listed above. This AD results from 
mandatory continuing airworthiness information (MCAI) issued by an 
airworthiness authority of another country to identify and correct an 
unsafe condition on an aviation product. The MCAI describes the unsafe 
condition as

    Subsequent to accidents involving Fuel Tank System explosions in 
flight * * * and on ground, * * * Special Federal Aviation 
Regulation 88 (SFAR88) * * * required a safety review of the 
aircraft Fuel Tank System * * *.
* * * * *
    Fuel Airworthiness Limitations are items arising from a systems 
safety analysis that have been shown to have failure mode(s) 
associated with an `unsafe condition' * * *. These are identified in 
Failure Conditions for which an unacceptable probability of ignition 
risk could exist if specific tasks and/or practices are not 
performed in accordance with the manufacturers' requirements.
* * * * *

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective February 16, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of February 16, 
2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of July 
21, 2006 (71 FR 34801, June 16, 2006).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (NPRM) to 
amend 14 CFR part 39 to include an AD that would apply to the specified 
products. That supplemental NPRM was published in the Federal Register 
on August 4, 2010 (75 FR 46864), and proposed to supersede AD 2006-12-
18, Amendment 39-14644 (71 FR 34801, June 16, 2006). That NPRM proposed 
to require revising the airplane flight manual (AFM); revising the 
Airworthiness Limitation (AWL) section; doing a resistance check, 
inspection, and jumper installation; and revising the AWL section. The 
MCAI states:


[[Page 1986]]


    Subsequent to accidents involving Fuel Tank System explosions in 
flight * * * and on ground, the FAA published Special Federal 
Aviation Regulation 88 (SFAR88) in June 2001. SFAR 88 required a 
safety review of the aircraft Fuel Tank System to determine that the 
design meets the requirements of FAR [Federal Aviation Regulation] 
Sec.  25.901 and Sec.  25.981(a) and (b).
    A similar regulation has been recommended by the JAA [Joint 
Aviation Authorities] to the European National Aviation Authorities 
in JAA letter 04/00/02/07/03-L024 of 3 February 2003. The review was 
requested to be mandated by NAA's [National Airworthiness 
Authorities] using JAR [Joint Aviation Requirement] Sec.  25.901(c), 
Sec.  25.1309.
    In August 2005 EASA [European Aviation Safety Agency] published 
a policy statement on the process for developing instructions for 
maintenance and inspection of Fuel Tank System ignition source 
prevention (EASA D 2005/CPRO, www.easa.eu.int/home/cert_policy_statements_en.html) that also included the EASA expectations with 
regard to compliance times of the corrective actions on the unsafe 
and the not unsafe part of the harmonised design review results. On 
a global scale the TC [type certificate] holders committed 
themselves to the EASA published compliance dates (see EASA policy 
statement). The EASA policy statement has been revised in March 
2006: The date of 31-12-2005 for the unsafe related actions has now 
been set at 01-07-2006.
    Fuel Airworthiness Limitations are items arising from a systems 
safety analysis that have been shown to have failure mode(s) 
associated with an `unsafe condition' as defined in FAA's memo 2003-
112-15 `SFAR 88--Mandatory Action Decision Criteria'. These are 
identified in Failure Conditions for which an unacceptable 
probability of ignition risk could exist if specific tasks and/or 
practices are not performed in accordance with the manufacturers' 
requirements.
    This EASA Airworthiness Directive mandates the Fuel System 
Airworthiness Limitations, comprising maintenance/inspection tasks 
and Critical Design Control Configuration Limitations (CDCCL) for 
the type of aircraft, that resulted from the design reviews and the 
JAA recommendation and EASA policy statement mentioned above.
    Revision History: PAD [proposed airworthiness directive] 06-
018R1 has been issued to endorse comments received for PAD 06-018 
and due to the change of the EASA policy statement on fuel tank 
safety on March 2006.

    You may obtain further information by examining the MCAI in the AD 
docket.

Comments

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

Explanation of Changes to This AD

    We have revised Table 1 of this AD to indicate the appropriate AFM 
for the identified airplane models. We have also added new paragraph 
(l) to this AD (and have reidentified subsequent paragraphs 
accordingly) to give credit to operators that might have included 
Shorts Advance Amendment Bulletin 1/2004, dated 7/13/04, into the 
incorrect AFM before the effective date of this AD. We have determined 
that the content of Shorts Advance Amendment Bulletin 1/2004 to AFM 
SB.5.2 and Shorts Advance Amendment Bulletin 1/2004 to AFM SB.6.2 is 
identical, except for the AFM number shown on the top of the document 
pages. Therefore, if an operator inserted the advance amendment 
bulletin intended for AFM SB.5.2 into AFM SB.6.2 or vise versa, before 
the effective date of this AD, the intent of the AFM revision required 
by paragraph (g) of this AD has been met, and is, therefore, acceptable 
for compliance with that requirement.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

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 a U.S. court of 
law. 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 required different actions in this AD 
from those in the MCAI in order to follow our FAA policies. Any such 
differences are described in a separate paragraph of the AD. These 
requirements, if any, take precedence over the actions copied from the 
MCAI.

Costs of Compliance

    We estimate that this AD will affect 54 products of U.S. registry.
    The actions that are required by AD 2006-12-18 and retained in this 
AD take about 41 work-hours per product, at an average labor rate of 
$85 per work hour. Required parts cost about $10 per product. Based on 
these figures, the estimated cost of the currently required actions is 
$3,495 per product.
    We estimate that it would take about 1 work-hour per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of the AD on U.S. operators to be $4,590, or $85 per product.

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 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 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 and placed it in the AD Docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone

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 removing Amendment 39-14644 (71 FR 
34801, June 16, 2006) and adding the following new AD:

2010-24-06 Short Brothers PLC: Amendment 39-16525. Docket No. FAA-
2010-0225; Directorate Identifier 2009-NM-203-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective February 
16, 2011.

Affected ADs

    (b) This AD supersedes AD 2006-12-18, Amendment 39-14644.

Applicability

    (c) This AD applies to all Short Brothers PLC Model SD3-60 
SHERPA, SD3-SHERPA, SD3-30, and SD3-60 airplanes, certificated in 
any category.

    Note 1:  This AD requires revisions to certain operator 
maintenance documents to include new inspections. Compliance with 
these inspections is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by these inspections, the operator may not be able 
to accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (m) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued damage tolerance of the affected structure. The FAA 
has provided guidance for this determination in Advisory Circular 
(AC) 25-1529.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Subsequent to accidents involving Fuel Tank System explosions in 
flight * * * and on ground, the FAA published Special Federal 
Aviation Regulation 88 (SFAR88) in June 2001. SFAR 88 required a 
safety review of the aircraft Fuel Tank System to determine that the 
design meets the requirements of FAR [Federal Aviation Regulation] 
Sec.  25.901 and Sec.  25.981(a) and (b).
    A similar regulation has been recommended by the JAA [Joint 
Aviation Authorities] to the European National Aviation Authorities 
in JAA letter 04/00/02/07/03-L024 of 3 February 2003. The review was 
requested to be mandated by NAA's [National Airworthiness 
Authorities] using JAR [Joint Aviation Requirement] Sec.  25.901(c), 
Sec.  25.1309.
    In August 2005 EASA [European Aviation Safety Agency] published 
a policy statement on the process for developing instructions for 
maintenance and inspection of Fuel Tank System ignition source 
prevention (EASA D 2005/CPRO, http://www.easa.eu.int/home/cert_policy_statements_en.html) that also included the EASA 
expectations with regard to compliance times of the corrective 
actions on the unsafe and the not unsafe part of the harmonised 
design review results. On a global scale the TC [type certificate] 
holders committed themselves to the EASA published compliance dates 
(see EASA policy statement). The EASA policy statement has been 
revised in March 2006: The date of 31-12-2005 for the unsafe related 
actions has now been set at 01-07-2006.
    Fuel Airworthiness Limitations are items arising from a systems 
safety analysis that have been shown to have failure mode(s) 
associated with an `unsafe condition' as defined in FAA's memo 2003-
112-15 `SFAR 88--Mandatory Action Decision Criteria'. These are 
identified in Failure Conditions for which an unacceptable 
probability of ignition risk could exist if specific tasks and/or 
practices are not performed in accordance with the manufacturers' 
requirements.
    This EASA Airworthiness Directive mandates the Fuel System 
Airworthiness Limitations, comprising maintenance/inspection tasks 
and Critical Design Control Configuration Limitations (CDCCL) for 
the type of aircraft, that resulted from the design reviews and the 
JAA recommendation and EASA policy statement mentioned above.
    Revision History: PAD [proposed airworthiness directive] 06-
018R1 has been issued to endorse comments received for PAD 06-018 
and due to the change of the EASA policy statement on fuel tank 
safety on March 2006.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Restatement of Requirements of AD 2006-12-18

Revision of Airplane Flight Manual (AFM)

    (g) Within 30 days after July 21, 2006 (the effective date of AD 
2006-12-18), revise the Limitations and Normal Procedures sections 
of the AFMs as specified in Table 1 of this AD to include the 
information in the applicable Shorts advance amendment bulletins as 
specified in Table 1 of this AD. The advance amendment bulletins 
address operation during icing conditions and fuel system failures. 
Thereafter, operate the airplane according to the limitations and 
procedures in the applicable advance amendment bulletin.

    Note 2:  The requirements of paragraph (g) of this AD may be 
done by inserting a copy of the applicable advance amendment 
bulletin into the AFM. When the applicable advance amendment 
bulletin has been included in general revisions of the AFM, the 
general revisions may be inserted into the AFM and the advance 
amendment bulletin may be removed, provided the relevant information 
in the general revision is identical to that in the advance 
amendment bulletin.

Resistance Check, Inspection, and Jumper Installation

    (i) Within 180 days after July 21, 2006: Perform the insulation 
resistance check, general visual inspections, and bonding jumper 
wire installations; in accordance with Shorts Service Bulletin 
SD330-28-37, SD360-28-23, SD360 SHERPA-28-3, or SD3 SHERPA-28-2; all 
dated June 2004; as applicable. If any defect or damage is 
discovered during any inspection or check required by this AD, 
before further flight, repair the defect or damage using a method 
approved by the Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA; the Civil Aviation Authority (CAA) (or 
its delegated agent); or EASA (or its delegated agent).

    Note 4:  For the purposes of this AD, a general visual 
inspection is: ``A visual examination of an interior or exterior 
area, installation, or assembly to detect obvious damage, failure, 
or irregularity. This level of inspection is made from within 
touching distance unless otherwise specified. A mirror may be 
necessary to ensure visual access to all surfaces in the inspection 
area. This level of inspection is made under normally available 
lighting conditions such as daylight, hangar lighting, flashlight, 
or droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''

New Requirements of This AD

Revision of AWL Section: New Limitations and CDCCLs

    (j) Within 90 days after the effective date of this AD: Revise 
the AWL section of the Instructions for Continued Airworthiness by 
incorporating maintenance manual Sections 5-20-01 and 5-20-02 as 
introduced by the Bombardier and Shorts TRs specified in Table 3 of 
this AD into the AWL section of the maintenance manuals for the 
airplane models specified in Table 3 of this AD. Doing this revision 
terminates the requirement to incorporate the temporary revisions 
specified in paragraph (h) of this AD. After doing this revision the 
temporary revisions required by paragraph (h) of this AD may be

    Note 5:  The requirements of paragraph (j) of this AD may be 
done by inserting a copy of the applicable TR into the applicable 
maintenance manual. When the TR has been included in general 
revisions of the AMM, the general revisions may be inserted in the 
AMM and the TR may be removed, provided the relevant information in 
the general revision is identical to that in the TR.

    (k) After accomplishing the actions specified in paragraph (j) 
of this AD, no alternative inspections, inspection intervals, or 
CDCCLs may be used unless the inspections, intervals, or CDCCLs are 
approved as an alternative method of compliance (AMOC), in 
accordance with the procedures specified in paragraph (m) of this 
AD.

Explanation of CDCCL Requirements

    Note 6:  Notwithstanding any other maintenance or operational 
requirements, components that have been identified as airworthy or 
installed on the affected airplanes before the revision of the AMM, 
as required by paragraph (h) or (j) of this AD, do not need to be 
reworked in accordance with the CDCCLs. However, once the AMM has 
been revised, future maintenance actions on these components must be 
done in accordance with the CDCCLs.

Credit for Actions Accomplished in Accordance With Other Service

Other FAA AD Provisions

    (m) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. Send information to ATTN: Todd

[[Page 1989]]

principal maintenance inspector (PMI) or principal avionics 
inspector (PAI), as appropriate, or lacking a principal inspector, 
your local Flight Standards District Office. The AMOC approval 
letter must specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: A Federal agency may not conduct or 
sponsor, and a person is not required to respond to, nor shall a 
person be subject to a penalty for failure to comply with a 
collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 5 
minutes per response, including the time for reviewing instructions, 
completing and reviewing the collection of information. All 
responses to this collection of information are mandatory. Comments 
concerning the accuracy of this burden and suggestions for reducing 
the burden should be directed to the FAA at: 800 Independence Ave., 
SW., Washington, DC 20591, Attn: Information Collection Clearance
