Airworthiness Directives; Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company 
Model 382, 382B, 382E, 382F, 382G, C-130A, C-130B, C-130BL, C130E, C-
130H, C 130H 30, C130J, C130J-30, EC130Q, HC130H, KC 130H, NC-130B, 
NC130, and WC-130H airplanes. This proposed AD was prompted by a report 
indicating that two elevator booster assemblies experienced significant 
hydraulic fluid leaks, caused by fatigue cracks in the actuator 
cylinder. This proposed AD would require an inspection to determine the 
part number of the elevator booster actuator, repetitive ultrasonic 
inspections of the actuator to detect cracking, and replacement of 
cracked elevator booster assemblies. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by September 
16, 2019.

NPRM because of those comments.
    The FAA will post all comments received, without change, to http://www.regulations.gov, including any personal information you provide. 
The FAA will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Discussion

    The FAA has received a report indicating that two elevator booster 
assemblies experienced significant hydraulic fluid leaks, caused by 
fatigue cracks in the actuator cylinder. Laboratory analysis of the 
cracked elevator booster actuators revealed an internal area in the 
cylinder body that is prone to fatigue crack initiation. The fatigue 
crack propagates unseen within the cylinder under normal operational 
loading until either a minor fluid leak becomes evident or the cylinder 
ruptures, creating a major leak. This condition, if not addressed, 
could result in a dual failure of the left and right actuator cylinders 
in the elevator booster assembly, which could lead to a significant 
reduction in controllability of the airplane.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Lockheed Martin Aeronautics Company Service 
Bulletin 382-27-51, Revision 1, dated January 17, 2018; and Lockheed 
Martin Aeronautics Company Service Bulletin 82-833, Revision 1, dated 
January 17, 2018. This service information describes procedures for an 
inspection to determine the part number of the elevator booster 
actuator, repetitive ultrasonic inspections of the elevator booster 
actuator at the forward-most end to detect cracking along the fluid 
transfer bore, left and right cylinders, and replacement of cracked 
elevator

booster assemblies. These documents are distinct since they apply to 
different airplane models.
    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.

FAA's Determination

    The FAA is proposing this AD because the agency 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.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.''

Impact on Intrastate Aviation in Alaska

    In light of the heavy reliance on aviation for intrastate 
transportation in Alaska, the FAA fully considered the effects of this 
proposed AD (including costs to be borne by affected operators) from 
the earliest possible stages of AD development. This proposed AD is 
based on those considerations, and was developed with regard to 
minimizing the economic impact on operators to the extent possible, 
consistent with the safety objectives of this proposed AD. In any 
event, the Federal Aviation Regulations require operators to correct an 
unsafe condition identified on an airplane to ensure operation of that 
airplane in an airworthy condition. The FAA has determined in this case 
that the proposed requirements are necessary and the indirect costs 
would be outweighed by the safety benefits of the proposed AD.

Differences Between This Proposed AD and the Service Information

    Lockheed Martin Aeronautics Company Service Bulletin 382-27-51, 
Revision 1, dated January 17, 2018; and Lockheed Martin Aeronautics 
Company Service Bulletin 82-833, Revision 1, dated January 17, 2018; 
specify to return parts to the manufacturer. This proposed AD would not 
include that requirement.

Costs of Compliance

    The FAA estimates that this proposed AD affects 7 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 
proposed AD:

                                                 Estimated Costs

                                    cycle.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspections. The FAA has 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.
    The FAA is 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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes and associated appliances to the 
Director of the System Oversight Division.

Regulatory Findings

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) 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

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

The Proposed Amendment

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