14 CFR Part 39

Airworthiness Directives; Viking Air Limited (Type Certificate 
No. A-815 Formerly Held by Bombardier Inc. and de Havilland, Inc.)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all Viking Air Limited (type certificate No. A-815 formerly held by 
Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. That AD 
currently requires repetitively inspecting the elevator control tabs 
for discrepancies, taking necessary corrective actions to bring all 
discrepancies within acceptable tolerances, and reporting certain 
inspection results to the FAA. This new AD retains the actions 
currently required in AD 2011-05-02 and removes the Supplemental Type 
Certificate (STC) SA01059SE condition in the Applicability section. 
This AD was prompted by our determination that we inadvertently omitted 
certain airplanes from the Applicability section. We are issuing this 
AD to correct the unsafe condition on these products.

DATES: This AD is effective October 3, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of March 
31, 2011 (76 FR 10220, February 24, 2011).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2011-05-02, Amendment 39-16611 (76 FR 10220, 
February 24, 2011). That AD applies to the specified products. The NPRM 
published in the Federal Register on June 10, 2011 (76 FR 34011). That 
NPRM proposed to retain all of the requirements of AD 2011-05-02 and 
add airplanes to the Applicability section removing the Supplemental 
Type Certificate (STC) SA01059SE condition.

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.

Conclusion

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

Interim Action

    We are continuing to evaluate the cause of the unsafe condition 
identified in this AD to enable us to obtain better insight into the 
nature, cause, and extent of excessive free-play in the elevator 
control tabs. Based on this evaluation, we may consider further 
rulemaking.

Costs of Compliance

    We estimate that this AD affects 65 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

     We estimate the following costs to do any necessary follow-on 
actions that will be required based on the results of the inspection. 
We have no way of determining the number of airplanes that may need 
this repair/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 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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

Adoption of the Amendment

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

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]

    The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
2011-05-02, Amendment 39-16611 (76 FR 10220, February 24, 2011), and 
adding the following new AD:

2011-18-11 Viking Air Limited (Type Certificate No. A-815 Formerly 
Held by Bombardier Inc. and de Havilland, Inc.): Amendment 39-16793; 
Docket No. FAA-2011-0597; Directorate Identifier 2011-CE-019-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective October 3, 2011.

(b) Affected ADs

    This AD supersedes AD 2011-05-02, Amendment 39-16611 (76 FR 
10220, February 24, 2011).

(c) Applicability

    This AD applies to Viking Air Limited (type certificate No. A-
815 formerly held by Bombardier Inc. and de Havilland, Inc.) Model 
DHC-3 airplanes, all serial numbers, that are certificated in any 
category.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 27, Flight Controls.

(e) Unsafe Condition

    This AD results from an evaluation of revisions to the 
manufacturer's maintenance manual that adds new repetitive 
inspections to the elevator control tabs. To require compliance with 
these inspections for U.S. owners and operators we are mandating 
these inspections through the rulemaking process. We are issuing 
this AD to add new repetitive inspections of the elevator control 
tabs. If these inspections are not done, excessive free-play in the 
elevator control tabs could develop. This condition could lead to 
loss of tab control linkage and severe elevator flutter. Such 
elevator flutter could lead to possible loss of control.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Paperwork Reduction Act Burden Statement

    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 Officer, AES-200.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, New York Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in the Related Information 
section of this AD.
    (2) Before using any approved AMOC, notify your Principal 
Maintenance Inspector or Principal Avionics Inspector, as 
appropriate, or lacking a principal inspector, your local Flight 
Standards District Office.
