14 CFR Part 39

Airworthiness Directives; Piper Aircraft, Inc.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Piper Aircraft, Inc. (type certificate previously held by The New Piper 
Aircraft Inc.) PA-28, PA-32, PA-34, and PA-44 airplanes. This AD was 
prompted by reports of control cable assembly failures that may lead to 
failure of the horizontal stabilator control system and could result in 
loss of pitch control. This AD requires inspections of the stabilator 
control system and replacement of parts as necessary. We are issuing 
this AD to correct the unsafe condition on these products.

DATES: This AD is effective March 11, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 11, 
2013.

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 August 2, 2012 (77 FR 
45979). That NPRM proposed to require inspections of the stabilator 
control system and replacement of parts as necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Request To Rescind the AD

    Gregory E. Sniegowski, Carl Poplawsky, and Eric Stendahl stated 
that since inspections of the control systems and pulleys are already 
part of the annual inspection, the requirements of this AD would seem 
to be redundant and that the NPRM should be withdrawn.
    We do not agree. The service difficulty report (SDR) database shows 
that certain Piper models have multiple reports of cracks, corrosion, 
failure of the turnbuckle, control cable fraying, or cable swage end 
breaks. This AD was prompted by reports concerning an accident on a 
Piper Model PA-32R-301T and an incident on a Piper Model PA-32R-300 
airplane.

NTSB Support

    Deborah A.P. Hersman, Chairman, National Transportation Safety 
Board (NTSB), stated that two special airworthiness information 
bulletins (SAIBs) have been issued that recommend inspecting the entire 
surface of each cable terminal, turnbuckle, or other cable fittings for 
corrosion or cracking. Within the past 2 years, the NTSB has 
investigated two accidents and one incident involving Piper airplanes 
where control cable assembly failures due to stress corrosion cracking 
led to failures of the horizontal stabilator control system. She stated 
that the fact these events continue to occur more than 10 years after 
the SAIBs were issued shows that the SAIBs were not effective. The NTSB 
supports the need for this AD.
    We concur with the findings by the NTSB.

Removal of Surface Corrosion

    Joseph Boenzi stated that we should revise the AD to allow an 
individual to remove the surface corrosion on a turnbuckle by using a 
cleaning agent and then making a determination if the part is 
airworthy. There have been reports that surface corrosion on 
turnbuckles could be easily removed with scotch-brite.
    We agree because Piper investigated the possibility of using 
scotch-brite to remove surface corrosion and found it to be acceptable. 
We will change this AD to reference the revised Piper Aircraft, Inc. 
Mandatory Service Bulletin No. 1245A, dated November 28, 2012, which 
incorporated cleaning agents and scotch-brite.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the change described previously and minor editorial 
changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (77 FR 45979, August 2, 2012) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 45979, August 2, 2012).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 34,013 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

             Action                    Labor cost             Parts cost            product         operators

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

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

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.
