Airworthiness Directives; Piper Aircraft, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Piper Aircraft, Inc. Model PA-46-500TP airplanes. This AD was prompted 
by a report of the wing upper skin joints being manufactured without 
sealant, which allows water to enter and stay in sealed, bonded 
stringers. This AD requires inspecting the upper wing surface for 
sealant; inspecting the wing stringers for water intrusion; inspecting 
for deformation and corrosion if evidence of water intrusion exists; 
and taking corrective actions as necessary. We are issuing this AD to 
correct the unsafe condition on these products.

DATES: This AD is effective February 17, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 17, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Piper Aircraft, 
Inc. Model PA-46-500TP airplanes. The NPRM published in the Federal 
Register on October 19, 2015 (80 FR 63151). The NPRM was prompted by a 
report of wing upper skin joints on Piper Aircraft, Inc. Model PA-46-
500TP airplanes being manufactured without sealant, which allows water 
to enter and stay in sealed, bonded stringers. The NPRM proposed to 
require inspecting the upper wing surface for sealant; inspecting the 
wing stringers for water intrusion; inspecting for deformation and 
corrosion if evidence of water intrusion exists; and taking corrective 
actions as necessary. We are issuing this AD to correct the unsafe 
condition on these products.

Related Service Information Under 1 CFR Part 51

    We reviewed Piper Aircraft, Inc. Service Bulletin No. 1262B, dated 
April 23, 2015. The service bulletin provides instructions for 
inspecting the upper wing surface for sealant and sealing or resealing 
(if necessary). This service bulletin also provides instructions for 
inspecting the wing stringers for water intrusion, and, if water 
intrusion was found as a result of the inspection, inspecting for 
corrosion or deformation. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section of this final rule.

[[Page 1503]]

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 63151, October 19, 
2015) 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 this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (80 FR 63151, October 19, 2015) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 63151, October 19, 2015).

Costs of Compliance

    We estimate that this AD affects 440 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
----------------------------------------------------------------------------------------------------------------
Inspection for sealant...........  2 work-hours x $85   Not Applicable.....            $170             $74,800
                                    per hour = $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any additional necessary 
inspections, rework of the stringers, and installation of sealant that 
will be required based on the results of the initial inspection. We 
have no way of determining the number of airplanes that might need this 
rework of the stringers and installation of sealant:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                   Action                              Labor cost               Parts cost     Cost per product
----------------------------------------------------------------------------------------------------------------
Rework stringers and seal skin joints......  12 work-hours x $85 per hour =            $200              $1,220
                                              $1,020.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.

List of Subjects in 14 CFR Part 39

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-01-01 Piper Aircraft, Inc.: Amendment 39-18359; Docket No. FAA-
2015-4213; Directorate Identifier 2015-CE-022-AD.

(a) Effective Date

    This AD is effective February 17, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Piper Aircraft, Inc. Model PA-46-500TP 
airplanes, serial numbers 4697001 through 4697528, certificated in 
any category.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 5700, Wings.

(e) Unsafe Condition

    This AD was prompted by a report of wing upper skin joints being 
manufactured without sealant, which allows water to enter and stay 
in sealed, bonded stringers. We are issuing this AD to prevent water 
from entering the stringers common to the upper wing skin. Left 
uncorrected, corrosion could develop, and freeze/thaw cycles of 
water at this location could cause deformation of the skin with 
follow-on disbonding between the stringer flanges and the inner 
surface of the wing skin. Consequently, the corrosion or disbonding 
could reduce the structural integrity of the wing.
