Airworthiness Directives; Airplanes Originally Manufactured by Lockheed for the Military as P2V Airplanes

Publication summary

We are adopting a new airworthiness directive (AD) for certain airplanes originally manufactured by Lockheed for the military as P2V airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires cleaning of the forward lower spar cap between wing stations 40 and 84.5 (right and left), and doing a detailed inspection for cracks, working fasteners, and other anomalies, including surface damage in the form of a nick, gouge, or corrosion; and repairing if necessary. This AD was prompted by a report of a significant crack in the principle wing structure. We are issuing this AD to detect and correct cracks, working fasteners, and other anomalies in the principle wing structure, which could cause significant loss of structural integrity of the wing.

Airworthiness Directives; Airplanes Originally Manufactured by 
Lockheed for the Military as P2V Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
airplanes originally manufactured by Lockheed for the military as P2V 
airplanes. This emergency AD was sent previously to all known U.S. 
owners and operators of these airplanes. This AD requires cleaning of 
the forward lower spar cap between wing stations 40 and 84.5 (right and 
left), and doing a detailed inspection for cracks, working fasteners, 
and other anomalies, including surface damage in the form of a nick, 
gouge, or corrosion; and repairing if necessary. This AD was prompted 
by a report of a significant crack in the principle wing structure. We 
are issuing this AD to detect and

[[Page 9167]]

correct cracks, working fasteners, and other anomalies in the principle 
wing structure, which could cause significant loss of structural 
integrity of the wing.

DATES: This AD is effective March 2, 2012 to all persons except those 
persons to whom it was made immediately effective by Emergency AD 2012-
03-51, issued on February 6, 2012, which contained the requirements of 
this amendment.

SUPPLEMENTARY INFORMATION: 

Discussion

    On February 6, 2012, we issued Emergency AD 2012-03-51, which 
requires cleaning of the forward lower spar cap between wing stations 
40 and 84.5 (right and left), and doing a detailed inspection for 
cracks, working fasteners, and other anomalies, including surface 
damage in the form of a nick, gouge, or corrosion; and repairing if 
necessary. That AD also requires sending inspection results (both 
positive and negative) to the FAA. This AD was prompted by a report of 
a significant crack in the principle wing structure on a Neptune 
Aviation Service, Inc. Model SP-2H (P2V-7) airplane. A crack 
approximately 24 inches long was found in the left side wing front spar 
and lower skin just outboard of the fuselage side of wing station 40. 
The crack propagated through the wing front spar web, lower chord, and 
wing lower skin through stringer No. 22 and aft to stringer No. 21. The 
cause of the cracking is unknown at this time. This condition, if not 
detected and corrected, could result in significant loss of structural 
integrity of the wing.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires cleaning of the forward lower spar cap between 
wing stations 40 and 84.5 (right and left), and doing a detailed 
inspection for cracks, working fasteners, and other anomalies, 
including surface damage in the form of a nick, gouge, or corrosion; 
and repairing if necessary. This AD also requires sending inspection 
results (both positive and negative) to the FAA.

Interim Action

    We consider this AD interim action. If final action is later 
identified, we might consider further rulemaking then.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because of a 
report of a significant crack in the principle wing structure on a 
Neptune Aviation Service, Inc. Model SP-2H (P2V-7) airplane. This 
condition, if not detected and corrected, could result in significant 
loss of structural integrity of the wing. Therefore, we find that 
notice and opportunity for prior public comment are impracticable and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2012-0107 and 
Directorate Identifier 2012-NM-018-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 38 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
        Action              Labor cost          Parts cost          Cost per product     Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Inspection              Up to 80 work-                   $100   Up to $6,900...........  Up to $262,200.
                         hours x $85 per
                         hour = $6,800.
----------------------------------------------------------------------------------------------------------------

    No definitive data are available for repair costs at this time.

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.

[[Page 9168]]

    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.
