RIN 2120-AA64

Airworthiness Directives; Piper Aircraft, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: This document withdraws a notice of proposed rulemaking (NPRM) 
that would have applied to all Piper Aircraft, Inc. (type certificate 
previously held by The New Piper Aircraft Inc.) Models PA-18 and PA-19 
airplanes. The proposed airworthiness directive (AD) would have 
required either moving all toggle-style magneto switches located on the 
left cabin panel, adjacent to the front seat, away from this position; 
or replacing these switches with FAA-approved, non-keyed, rotary-style 
switches. Since issuance of the NPRM, the FAA has re-evaluated this 
airworthiness concern and determined that an unsafe condition does not 
exist that would warrant AD action. This withdrawal does not prevent 
the FAA from initiating future rulemaking on this subject.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM published in the Federal Register on July 19, 2012 (77 FR 
42455). That NPRM proposed to require you to either move all toggle-
style magneto switches located on the left cabin panel, adjacent to the 
front seat, away from this position; or replace these switches with 
FAA-approved, non-keyed, rotary-style switches.
    Because of the comments received on the NPRM (77 FR 42455, July 19, 
2012), the FAA re-evaluated the data collected on the safety concern 
and concluded that:
     an unsafe condition warranting AD action does not exist; 
and
     the associated level of risk does not warrant AD action.
    To mitigate the safety concern from recurring, the FAA may take 
another airworthiness action such as a special airworthiness 
information bulletin (SAIB) to recommend the actions contained in the 
proposed rule and capture the concerns identified by the public during 
the NPRM (77 FR 42455, July 19, 2012) comment period.
    Withdrawal of this NPRM (77 FR 42455, July 19, 2012) constitutes 
only such action and does not preclude the agency from issuing future 
rulemaking on this issue, nor does it commit the agency to any course 
of action in the future.

Regulatory Findings

    Since this action only withdraws an NPRM, it is neither a proposed 
nor a final rule and therefore, is not covered under Executive Order 
12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979).

List of Subjects in 14 CFR Part 39

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

The Withdrawal

    Accordingly, the notice of proposed rulemaking (NPRM), FAA-2012-
0756, published in the Federal Register on July 19, 2012 (77 FR 42455), 
is withdrawn.
