Download as PDF Federal Register / Vol. 77, No. 139 / Thursday, July 19, 2012 / Proposed Rules comments. 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 proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.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 emcdonald on DSK67QTVN1PROD with PROPOSALS On March 29, 2000, we issued AD 2000–07–11, Amendment 39–11665 (65 FR 19305, April 11, 2000). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2000–07–11 (65 FR 19305, April 11, 2000), we determined the unsafe condition no longer exists. Review of the Piaggio Model P–180 service history and maintenance requirements shows that regularly scheduled annual inspections address this issue. Therefore, the need to continue to address this subject as an unsafe condition through an AD is not necessary. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued 2012–0095–CN, dated May 31, 2012 (referred to after this as ‘‘the MCAI’’). The MCAI states: After a 1999 training session during which conflicting inputs were given to the brake pads between pilot and copilot, a brake system rod was found deflected. The rod, in this bent condition, could possibly wear and damage the tubings connected to the brake valves, with consequent fluid leakage. Prompted by these findings, PAI issued Service Bulletin (SB) 80–0107, providing instructions for repetitive inspections of the affected rods and tubings. As this was considered to be a potentially unsafe condition, Registro Aeronautico Italiano (RAI), the predecessor of ENAC (Ente Nazionale per l’Aviazione Civile), issued ` Prescrizione di Aeronavigabilita (PA) No. 1999–219, which required the repetitive inspections as detailed in PAI SB 80–0107 and, depending on findings, replacement of rod or tubing. Since that AD was issued, the repetitive inspections of SB 80–0107 have been included as regular tasks into the maintenance schedule of both Avanti and Avanti II aeroplanes. In addition, no other cases of brake system bent rods have been reported, nor have any rods been replaced for damage in the P.180 fleet since that occurrence. Based on the available information, this is no longer considered to be an unsafe condition. Prompted by this VerDate Mar<15>2010 15:06 Jul 18, 2012 Jkt 226001 determination, PAI issued Revision ZZ of SB 80–0107, which cancels the original SB 80– 0107. For the reasons described above, this Notice is issued to cancel ENAC PA no. 1999–219 dated 03 May 1999. You may obtain further information by examining the MCAI in the AD docket. FAA’s Determination We propose this AD because we evaluated all available information and determined the existing AD is no longer necessary. Proposed AD Requirements This proposed AD would rescind AD 2000–07–11 (65 FR 19305, April 11, 2000). Authority for this Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

Model PA–18 airplanes with magneto switches located on the left cabin panel, adjacent to the front seat, were caused by pilots unknowingly turning off the magneto switches and causing in-flight engine shutdowns. In each event, the pilot was performing other flight tasks, such as re-trimming the airplane, and the pilot’s arm and/or article of clothing accidently turned off the magneto switches. Those parties that may desire an alternative method of compliance (AMOC) are encouraged to work together with pertinent type clubs toward a single global AMOC. Any Piper Aircraft, Inc. Model PA–18 airplane with the magneto switch currently located away from the left cabin panel, adjacent to the front seat, including those already placed on an airplane’s wing root, is not at a high risk of an inadvertent in-flight engine shutdown and loss of flight control and are not the subject of this proposed AD. This condition, if not corrected, could result in engine shut down and possible loss of control. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require removing the magneto switch and ignition leads from the left cabin panel adjacent to the front seat and install a key-type ignition switch on the instrument panel. Costs of Compliance We estimate that this proposed AD affects 295 airplanes of U.S. registry.

Discussion

    Three forced landings of Piper Aircraft, Inc. Model PA-18 airplanes 
with magneto switches located on the left cabin panel, adjacent to the 
front seat, were caused by pilots unknowingly turning off the magneto 
switches and causing in-flight engine shutdowns. In each event, the 
pilot was performing other flight tasks, such as re-trimming the 
airplane, and the pilot's arm and/or article of clothing accidently 
turned off the magneto switches.
    Those parties that may desire an alternative method of compliance 
(AMOC) are encouraged to work together with pertinent type clubs toward 
a single global AMOC.
    Any Piper Aircraft, Inc. Model PA-18 airplane with the magneto 
switch currently located away from the left cabin panel, adjacent to 
the front seat, including those already placed on an airplane's wing 
root, is not at a high risk of an inadvertent in-flight engine shutdown 
and loss of flight control and are not the subject of this proposed AD.
    This condition, if not corrected, could result in engine shut down 
and possible loss of control.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require removing the magneto switch and 
ignition leads from the left cabin panel adjacent to the front seat and 
install a key-type ignition switch on the instrument panel.

Costs of Compliance

    We estimate that this proposed AD affects 295 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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

    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.

[[Page 42457]]

    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),
    (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.
