Airworthiness Directives; Learjet Inc.

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

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: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• 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

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.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the

report of an uncontrolled pitch trim 

runaway during descent. We are issuing 

this AD to prevent loss of control of the 

airplane. 

DATES: This AD is effective July 12, 2011 

to all persons except those persons to 

whom it was made immediately 

effective by Emergency AD 2011–12–51, 

issued on May 27, 2011, which 

contained the requirements of this 

amendment. 

We must receive comments on this 

AD by August 11, 2011.
