SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That NPRM published in the Federal Register on E:\FR\FM\24FER1.SGM 24FER1 Federal Register / Vol. 76, No. 37 / Thursday, February 24, 2011 / Rules and Regulations December 7, 2010 (75 FR 75932). That NPRM proposed to require repetitively inspecting the elevator control tabs for discrepancies and, if any discrepancies are found, taking necessary corrective actions to bring all discrepancies within acceptable tolerances. That NPRM also proposed a reporting requirement requesting information when the total maximum free play of the elevator servo tab and trim tab relative to the elevator exceeds 1.0 degree (this is equal to a maximum displacement of 0.070″ at the trailing edge of the servo tab). Collecting this information will help us better understand the service history related to excessive free-play in the elevator control tabs for various Model DHC–3 engine configurations. 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: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and 10221 • 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: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspection .............. 1 work-hour × $85 per hour = $85 per inspection cycle. Not applicable ...................... $85 per inspection cycle ...... $5,525 per inspection cycle. 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: ON-CONDITION COSTS Labor cost Minimum repair ................................ Moderate repair ............................... Maximum repair ............................... jlentini on DSKJ8SOYB1PROD with RULES Action Parts cost 1 work-hour × $85 per hour = $85 ............................................................ 3 work-hours × $85 per hour = $255 ........................................................ 6 work-hours × $85 per hour = $510 ........................................................ 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. 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. Regulatory Findings This AD will not have federalism implications under Executive Order Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

The MCAI states: Compass mismatch (up to loss of heading information) were reported by operators, due to ferro-magnetic masses (like the telescopic Tow-Bar) stowed in the baggage compartment. A limitation was added to the approved Airplane Flight Manual, stating that the towing bar P/N 01–1227–0000 or similar ferromagnetic masses are prohibited to be carried in the baggage compartment. We require the incorporation of Piaggio Aero Industries S.p.A. and Piaggio Aero Industries (Piaggio) Temporary Change No. 7, into the Pilot’s Operating Handbook and EASA Approved Airplane Flight Manual Rep. 6591, issued: February 24, 2009, and Temporary Change No. 11 into the EASA Approved Airplane Flight Manual Rep. 180–MAN–0010–01100, issued: February 24, 2009, and installation of a placard. 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 have considered the comment received. Comment Issue: Study Relocation of Magnetic Flux Valves James Wright stated that investigation into the feasibility of relocating the magnetic flux valves to an area less susceptible to magnetic interference may be a better course of action. We infer that the commenter requests that we withdraw the AD action and relocate the magnetic flux valves to an area less susceptible to magnetic interference. We do not agree with the commenter. The current airplane flight manual limitation stipulates: The towing bar TRONAIR p/n 01–1227– 0000 or other ferromagnetic masses with comparable mass and length are prohibited to be carried in the baggage compartment. Additionally, Piaggio evaluated the possibility of relocating the flux valve and concluded it should remain in its current location. Piaggio confirmed that a new tow bar made of aluminum is available and can be used on Model PIAGGIO P–180 airplanes. E:\FR\FM\24FER1.SGM 24FER1

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires repetitively inspecting the 
elevator control tabs for discrepancies and, if any discrepancies are 
found, taking necessary corrective actions to bring all discrepancies 
within acceptable tolerances. This AD also requires reporting certain 
inspection results to the FAA. This AD was prompted by an evaluation of 
revisions to the manufacturer's maintenance manual that adds new 
repetitive inspections of the elevator control tabs. To require 
compliance with these inspections for U.S. owners and operators we are 
mandating the 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.

DATES: This AD is effective March 31, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 31, 
2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on

[[Page 10221]]

December 7, 2010 (75 FR 75932). That NPRM proposed to require 
repetitively inspecting the elevator control tabs for discrepancies 
and, if any discrepancies are found, taking necessary corrective 
actions to bring all discrepancies within acceptable tolerances.
    That NPRM also proposed a reporting requirement requesting 
information when the total maximum free play of the elevator servo tab 
and trim tab relative to the elevator exceeds 1.0 degree (this is equal 
to a maximum displacement of 0.070'' at the trailing edge of the servo 
tab). Collecting this information will help us better understand the 
service history related to excessive free-play in the elevator control 
tabs for various Model DHC-3 engine configurations.

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:
     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.

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.

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

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

    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.

List of Subjects in 14 CFR Part 39

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

Adoption of the Amendment

    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 adding the following new airworthiness 
directive (AD):

2011-05-02 Viking Air Limited (Type Certificate No. A-815 Formerly 
Held by Bombardier Inc. and de Havilland, Inc.): Amendment 39-16611; 
Docket No. FAA-2010-1192; Directorate Identifier 2010-CE-020-AD.

Effective Date

    (a) This AD is effective March 31, 2011.

[[Page 10222]]

Affected ADs

    (b) None.

Applicability

    (c) 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:
    (1) Do not have the new elevator servo tab and redundant control 
linkage installed according to Supplemental Type Certificate (STC) 
No. SA01059SE; and
    (2) Are certificated in any category.

Subject

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

Unsafe Condition

    (e) 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.

Compliance

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