Airworthiness Directives; Alpha Aviation Design Limited Model R2160 Airplanes, 66089-66091 [E7-23017]

Download as PDF Federal Register / Vol. 72, No. 227 / Tuesday, November 27, 2007 / Proposed Rules Reason (e) The mandatory continuing airworthiness information (MCAI) states: The Type Certificate Holder (TCH) has received several reports of failed Rudder torque tube assemblies. The torque tube assemblies are subject to repetitive inspection in accordance Airworthiness Directive 2060 PRE 80. The recent failures occurred in service after the inspections required by AD 2060 PRE 80 had been performed. In the event of such failures, loss of directional control through both the Rudder and Nosewheel Steering may occur. The TCH has also received reports of loose rivets attaching the inboard Anchor Assembly to the Starboard Torque Tube. The MCAI requires the inspection of the rudder torque tube assemblies and hubs for cracking and loose rivets with conditional correction or replacement in accordance with de Havilland Support Limited Service Bulletin B121/65, Issue 2, dated August 10, 2005. Actions and Compliance (f) Unless already done, do the following actions: (1) Within 100 hours time-in-service (TIS) after the effective date of this AD and thereafter at intervals not to exceed 100 hours TIS, inspect the Rudder Torque Tube Assemblies following de Havilland Support Limited Service Bulletin B121/65, Issue 2, dated August 10, 2005. (2) Before further flight, replace any cracked Rudder Torque Tube Assemblies and correct any loose rivets in the Rudder Torque Tube Assemblies that are found in the inspections required in paragraph (f)(1) of this AD, following de Havilland Support Limited Service Bulletin B121/65, Issue 2, dated August 10, 2005. (3) After the effective date of this AD, used rudder torque assemblies held as spares for British Aerospace Aircraft Group, Scottish Division, Model Beagle B.121 Series 1, 2, 3 airplanes must be inspected following de Havilland Support Limited Service Bulletin B121/65, Issue 2, dated August 10, 2005, and found free of cracks prior to installation.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as distortion of the rudder bars due to rudder control forces during aerobatic operation and nose wheel steering reaction forces. Rudder bar distortion could result in reduced control or loss of control. The proposed AD would require actions that are PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 66089 intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by December 27, 2007. You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments. • Fax: (202) 493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590. • Hand Delivery: U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this E:\FR\FM\27NOP1.SGM 27NOP1 66090 Federal Register / Vol. 72, No. 227 / Tuesday, November 27, 2007 / Proposed Rules proposed AD because of those comments. We will post all comments we receive, without change, to https:// regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion In 1987, we issued AD 87–08–01, Amendment 39–5601, and in 1999, we issued AD 99–01–04, Amendment 39– 10971. Those two ADs required actions intended to address an unsafe condition on the products listed above. We since determined that it is necessary to expand the airplane applicability of AD 99–01–04 to require rudder bar replacement on Alpha Aviation Design Limited Model R2160 airplanes, serial numbers 1 through 378. The requirement to replace the rudder bars makes the inspection requirement of AD 87–08–01 no longer necessary. The Civil Aviation Authority, which is the aviation authority for New Zealand, has issued AD DCA/R2000/ 23B, dated October 25, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states that rudder control forces during aerobatic operation and nose wheel steering reaction forces may cause rudder bar distortion. Rudder bar distortion could result in reduced control or loss of control. The MCAI requires you to replace the left and right rudder bars with reinforced rudder bars. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Alpha Aviation has issued Service Bulletin AA–SB–27–003, dated October 19, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. ycherry on PROD1PC66 with PROPOSALS FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or VerDate Aug<31>2005 15:23 Nov 26, 2007 Jkt 214001 develop on other products of the same type design. Differences Between This Proposed 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 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 proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. 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 this 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. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 9 products of U.S. registry. We also estimate that it would take about 3 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $657 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $8,073, or $897 per product. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. 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. § 39.13 Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 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.

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. This 
proposed AD results from mandatory continuing airworthiness information 
(MCAI) originated by an aviation authority of another country to 
identify and correct an unsafe condition on an aviation product. The 
MCAI describes the unsafe condition as distortion of the rudder bars 
due to rudder control forces during aerobatic operation and nose wheel 
steering reaction forces. Rudder bar distortion could result in reduced 
control or loss of control. 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 December 27, 
2007.

receive about this proposed AD.

Discussion

    In 1987, we issued AD 87-08-01, Amendment 39-5601, and in 1999, we 
issued AD 99-01-04, Amendment 39-10971. Those two ADs required actions 
intended to address an unsafe condition on the products listed above.
    We since determined that it is necessary to expand the airplane 
applicability of AD 99-01-04 to require rudder bar replacement on Alpha 
Aviation Design Limited Model R2160 airplanes, serial numbers 1 through 
378. The requirement to replace the rudder bars makes the inspection 
requirement of AD 87-08-01 no longer necessary.
    The Civil Aviation Authority, which is the aviation authority for 
New Zealand, has issued AD DCA/R2000/23B, dated October 25, 2007 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states that rudder 
control forces during aerobatic operation and nose wheel steering 
reaction forces may cause rudder bar distortion. Rudder bar distortion 
could result in reduced control or loss of control.
    The MCAI requires you to replace the left and right rudder bars 
with reinforced rudder bars.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Alpha Aviation has issued Service Bulletin AA-SB-27-003, dated 
October 19, 2007. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 9 products of U.S. registry. We also estimate that 
it would take about 3 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $657 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $8,073, or $897 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 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 this 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

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, 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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by removing Amendment 39-5601 and 
Amendment 39-10971, and adding the following new AD:

Alpha Aviation Design Limited: Docket No. FAA-2007-0249; Directorate 
Identifier 2007-CE-088-AD.

Comments Due Date

    (a) We must receive comments by December 27, 2007.

Affected ADs

    (b) This AD supersedes AD 87-08-01, Amendment 39-5601; and AD 
99-01-04, Amendment 39-10971.

Applicability

    (c) This AD applies to Model R2160 airplanes, serial numbers 1 
through 378, that:
    (1) Are certificated in any category; and
    (2) Have not installed the improved design rudder bars part 
number (P/N) 27.40.31.010 and P/N 27.40.31.020 following either 
Avions Pierre Robin Service Bulletin No. 143, dated September 8, 
1995, or Alpha Aviation Service Bulletin AA-SB-27-003, dated October 
19, 2007.

Subject

    (d) Air Transport Association of America (ATA) Code 27: Flight 
Controls.

[[Page 66091]]

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states that rudder control forces during aerobatic operation and 
nose wheel steering reaction forces may cause rudder bar distortion. 
Rudder bar distortion could result in reduced or loss of control. 
The MCAI requires you to replace the left and right rudder bars with 
reinforced rudder bars.

Restatement of Requirements of AD 99-01-04

    (f) For airplanes with serial numbers 250 through 378: Unless 
already done, within the next 50 hours time-in-service (TIS) after 
March 12, 1999 (the effective date of AD 99-01-04) replace the left 
and right rudder bars, part number (P/N) 27.23.01.010 (left) and P/N 
27.23.01.020 (right), with the reinforced rudder bars, P/N 
27.40.31.010 (left) and P/N 27.40.31.020 (right) or FAA-equivalent 
part numbers, following Alpha Aviation Service Bulletin AA-SB-27-
003, dated October 19, 2007.

New Requirements of This AD: Actions and Compliance

    (g) For airplanes with serial numbers 1 through 249: Unless 
already done, within the next 50 hours TIS after the effective date 
of this AD or within the next 3 months after the effective date of 
this AD, whichever occurs first, replace the left and right rudder 
bars, P/N 27.23.05.010 (left) and P/N 27.23.05.020 (right), with the 
reinforced rudder bars, P/N 27.40.31.010 (left) and P/N 27.40.31.020 
(right) or FAA-equivalent part numbers, following Alpha Aviation 
Service Bulletin AA-SB-27-003, dated October 19, 2007.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: No differences.
