Airworthiness Directives; Learjet Inc. Model 45 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. That AD currently requires, for certain 
airplanes, repetitive inspections for chafing and other damage of the 
case drain tube from the hydraulic pump case installed on the left-hand 
engine, and corrective action if necessary. That AD also requires, for 
all airplanes, repetitive inspections for discrepancies of the left 
engine's nacelle tubing, repetitive inspections for evidence of fluid 
leakage within the left engine accessory compartment, and corrective 
actions if necessary. This new AD also requires replacing the left 
engine fuel and hydraulic tubing and installing a tubing support 
channel, which terminates the repetitive inspections required in the 
existing AD. This new AD also removes airplanes from the applicability. 
This AD was prompted by reports of chafed hydraulic tubes in the left-
hand engine. We are issuing this AD to prevent chafed hydraulic tubes 
in the left-hand engine and consequent hydraulic tube failure and 
uncontrolled loss of flammable fluid within the engine cowling, which 
could result in a fire in the engine nacelle and loss of control of the 
airplane.

DATES: This AD is effective August 1, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 1, 
2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of June 
17, 2009 (74 FR 26288, June 2, 2009).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede airworthiness directive (AD) 2009-11-13, Amendment 
39-15923 (74 FR 26288, June 2, 2009). That AD applies to the specified 
products. The NPRM published in the Federal Register on August 23, 2010 
(75 FR 51701). That NPRM proposed to require, for certain airplanes, 
repetitive inspections for chafing and other damage of the case drain 
tube from the hydraulic pump case installed on the left-hand engine, 
and corrective action if necessary. That NPRM also proposed to require, 
for all airplanes, repetitive inspections for discrepancies of the left 
engine's nacelle tubing, repetitive inspections for evidence of fluid 
leakage within the left engine accessory compartment, and corrective 
actions if necessary. That NPRM also proposed to require replacing the 
left engine fuel and hydraulic tubing and installing a tubing support 
channel which terminates the repetitive inspections required in the 
existing AD.

Comments

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

Request to Reference Later Revisions of the Maintenance Manual

    Marlin Priest requested that we revise the NPRM to reference later 
revisions of the maintenance manual, as operators may not have the 
prior revisions available. The commenter pointed out that Table 3 of 
the NPRM references Learjet 45 Maintenance Manual MM-104, Revision 47, 
dated March 30, 2009; and Learjet 40 Maintenance Manual MM-105, 
Revision 15, dated March 30, 2009. The commenter stated that Learjet 45 
Maintenance Manual MM-104 is currently at a later revision.
    We disagree with the request to refer to a later revision of 
Learjet 45 Maintenance Manual MM-104. The reference to that maintenance 
manual appears in requirements that are simply restated from AD 2009-
11-13. Operators were required to have accomplished those actions 
within 50 flight hours after June 17, 2009 (the effective date of AD 
2009-11-13). Therefore, we find it unnecessary to reference later 
versions of the maintenance manual in Table 3 of this AD. In addition, 
we cannot refer to ``the latest revision of the maintenance manual'' in 
this AD because using the phrase ``or later FAA-approved revisions,'' 
violates Office of the Federal Register regulations for approving 
materials that are incorporated by reference. However, affected 
operators may request approval to use a later revision of the 
referenced maintenance manual as an alternative method of compliance 
under the provisions of paragraph (n) of the final rule. No change has 
been made to this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 358 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

[[Page 37249]]

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.
