14 CFR Part 39

[Docket No. FAA-2012-0251; Directorate Identifier 2012-CE-002-AD; 
Amendment 39-17058; AD 2012-10-09]
RIN 2120-AA64


Airworthiness Directives; Piper Aircraft, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Piper Aircraft, Inc. (type certificate previously held by 
The New Piper Aircraft Inc.) Models PA-31T and PA-31T1 airplanes. That 
AD currently requires correcting a model identification error on the 
aircraft data plate. Since we issued that AD, we have become aware that 
some owner/operators of the affected airplanes modified the aircraft 
data plate in error because of confusion in the serial number 
applicability. Because of the confusion, the manufacturer has issued 
new service information to clarify affected airplane serial numbers. 
This new AD requires determining the airplane model based on the serial 
number and modifying the aircraft data plate to properly identify the 
airplane model. This new AD also requires doing a detailed search for 
all applicable airworthiness related documents that apply to any 
airplane that has an incorrectly marked data plate and take necessary 
corrective actions based on the search findings. We are issuing this AD 
to correct the unsafe condition on these products.

DATES: This AD is effective June 29, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 29, 
2012.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 80-11-06, amendment 39-3776 (45 FR 35309, May 
27, 1980). That AD applies to the specified products. The NPRM 
published in the Federal Register on March 9, 2012 (77 FR 14316). The 
NPRM proposed to retain all requirements of AD 80-11-06, amendment 39-
3776 (45 FR 35309, May 27, 1980) and clarify the serial number 
applicability of the affected model airplanes. The NPRM also proposed 
to require a detailed search for all applicable airworthiness related 
documents that apply to any airplane that has an incorrectly marked 
aircraft data plate and take necessary corrective actions.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 14316, March 9, 
2012) 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 (77 FR 14316, March 9, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 14316, March 9, 2012).

Costs of Compliance

    We estimate that this AD affects 158 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
              Action                      Labor cost             Parts cost           product        operators

                                     hour = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary modification 
and/or records search that will be required based on the results of the 
inspection. We have no way of determining the number of aircraft that 
might need modification:

 incorrectly marked aircraft data plate.
----------------------------------------------------------------------------------------------------------------

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 have determined that 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.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 1100, Placards and Markings.

(e) Unsafe Condition

    This AD was prompted by reports that some owner/operators of the 
affected airplanes modified the aircraft data plate in error because 
of confusion in the serial number applicability. We are issuing this 
AD to correct the unsafe condition on these products.

(f) Compliance

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

(g) Inspect the Aircraft Data Plate

    Within the next 100 hours after June 29, 2012 (the effective 
date of this AD), inspect the markings on the aircraft data plate. 
Do the inspection following Part I of Piper Aircraft, Inc. Mandatory 
Service Bulletin No. 1235, dated November 3, 2011.
    (1) If the aircraft data plate is correctly marked, make a 
logbook entry showing compliance with this AD, and no further action 
is required.
    (2) If the aircraft data plate is incorrectly marked, continue 
with paragraphs (h) and (i) of this AD.

(h) Modify the Aircraft Data Plate

    Before further flight after the inspection required in paragraph 
(g) of this AD, modify the aircraft data plate following Part II of 
Piper Aircraft, Inc. Mandatory Service Bulletin No. 1235, dated 
November 3, 2011.

(i) Detailed Aircraft Records Search

    Before further flight after the modification required in 
paragraph (h) of this AD:
    (1) Do a detailed search of the aircraft maintenance records and 
documents to include, but not limited to, ADs, special airworthiness 
information bulletins (SAIBs), service bulletins (SBs), and other 
service documents; installed supplemental type certificates (STCs) 
and parts manufacturing approval (PMAs); and instructions for 
continued airworthiness (ICAs). Each document found must be assessed 
to ensure proper actions have been made to maintain airworthiness as 
affected by the model number of the aircraft. Part 135 operators and 
other operators utilizing FAA-approved maintenance programs will 
need to address changes to their inspection programs and related 
documents.

    Note 1 to paragraph (i)(1) of this AD: Although some of the 
above documents may not be mandatory for compliance, it is still 
necessary to evaluate them to ensure that any voluntary compliance 
does not negatively affect the airworthiness of the airplane.

    (2) Identify all discrepant conditions for misidentified 
aircraft and coordinate with the geographic Flight Standards 
District Office (FSDO) and the Atlanta Aircraft Certification Office 
(ACO) to determine necessary corrective actions. Also, coordinate 
with the geographic FSDO to arrange for revisions to the 
airworthiness certificate, registration, and other potential 
document/certificate revisions. The following is a list of example 
discrepant conditions that may be found during the records search:
    (i) An AD was complied with that was applicable to the incorrect 
model, but not applicable to the corrected model.
    (ii) A required AD for the corrected model was not complied 
with.
    (iii) A maintenance action was performed that was recommended, 
but not mandatory, for the incorrect model, but not applicable to 
the corrected model.
    (iv) A PMA part was installed that was applicable for the 
incorrect model, but not for the corrected model.
    (v) An STC was installed that was applicable for the incorrect 
model, but not for the corrected model.
    (vi) An STC was installed that was applicable for both the 
incorrect and corrected model, but all related, applicable ADs for 
the corrected model were not complied with.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta Aircraft Certification Office (ACO), 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the ACO, send it to the attention of the 
person identified in the Related Information section of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) AMOCs approved for AD 80-11-06 (45 FR 35309, May 27, 1980), 
are approved as AMOCs for this AD.
