Airworthiness Directives; Learjet Inc. 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to certain Learjet Inc. Model 

60 airplanes. The existing AD currently 

requires determining if a certain fuel 

crossflow tube is installed; and followon/corrective actions, as applicable. 

Since we issued that AD, we have 

received a report that airplanes 

produced since 2003 might also be 

subject to the unsafe condition; and that 

the minimum allowable clearance is not 

established in the airplane maintenance 

information, and therefore, must be 

addressed by this proposed AD. This 

proposed AD would retain all actions in 

the previous AD, and would require 

determining if a certain fuel crossflow 

tube is installed, performing repetitive 

measurements of the fuel crossflow tube 

and surrounding valves and cables, and 

doing corrective actions if applicable. In 

addition, this proposed AD expands the 

applicability of the existing AD. We are 

proposing this AD to prevent chafing 

and consequent failure of the fuel 

crossflow tube due to inadequate 

clearance between the tube and the 

flight control cables, which could result 

in loss of fuel from one fuel tank during 

normal operating conditions or loss of 

fuel from both main fuel tanks during 

fuel cross-feeding operations. 

DATES: We must receive comments on 

this proposed AD by September 27, 

2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

On September 16, 2003, we issued AD 

2003–19–11, Amendment 39–13314 (68 

FR 55812, September 29, 2003), for 

certain Learjet Inc. Model 60 airplanes. 

That AD requires a review of airplane 

maintenance records or an inspection to 

determine if a fuel crossflow tube 

having a certain part number is 

installed; and follow-on/corrective 

actions, as applicable. That AD resulted 

from reports of chafing of the fuel 

crossflow tube by flight control cables. 

We issued that AD to prevent chafing 

and consequent failure of the fuel 

crossflow tube due to inadequate 

clearance between the tube and the 

flight control cables, which could result 

in loss of fuel from one fuel tank during 

normal operating conditions or loss of 

fuel from both main fuel tanks during 

fuel cross-feeding operations. 

Actions Since Existing AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003) Was Issued 

Since we issued AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003), we have received 

a report that airplanes produced since 

2003 might be subject to the unsafe 

condition; and that the minimum 

allowable clearance is not established in 

the airplane maintenance information, 

and therefore, must be addressed by this 

proposed AD. 

FAA’s Determination 

We are proposing 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. 

Proposed AD Requirements 

This proposed AD would retain all 

requirements of AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003). This proposed AD 

would retain all actions in the previous 

AD, and would require determining if a 

certain fuel crossflow tube is installed, 

performing repetitive measurements of 

the fuel crossflow tube and surrounding 

valve and cables, and doing corrective 

actions if applicable.

Federal Register / Vol. 78, No. 156 / Tuesday, August 13, 2013 / Proposed Rules 49233 

Differences Between the AD and the 

Service Information 

Although Bombardier Alert Service 

Bulletin A60–28–3, Revision 2, dated 

October 26, 1998, applies to Learjet Inc. 

Model 60 airplanes, serial numbers 60– 

001 through 60–145 inclusive, this AD 

applies to Learjet Inc. Model 60 

airplanes, serial numbers 60–001 

through 60–409 inclusive. Airplanes 

having serial numbers 60–001 through 

60–409 are subject to the unsafe 

condition. In addition, the minimum 

allowable clearance is not established in 

the airplane maintenance information, 

and therefore, a repetitive measurement 

is necessary. This difference has been 

coordinated with Learjet Inc. 

Change to Existing AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003) 

This proposed AD would retain all 

requirements of AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003). Since AD 2003– 

19–11 was issued, the AD format has 

been revised, and certain paragraphs 

have been rearranged. As a result, the 

corresponding paragraph identifiers 

have changed in this proposed AD, as 

listed in the following table: 

REVISED PARAGRAPH IDENTIFIERS

Requirement in AD

paragraph (b) paragraph (h) 

paragraph (c) paragraph (i) 

paragraph (d) paragraph (j) 

Costs of Compliance 

We estimate that this proposed AD 

affects 264 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection [retained actions from AD 2003– 

19–11, Amendment 39–13314 (68 FR 

55812, September 29, 2003)].

2 work-hours × $85 per hour = $170 ............. $2 $172 $45,408 

We estimate the following costs to do 

any necessary replacement that would 

be required based on the results of the 

proposed inspection. We have no way of 

determining the number of aircraft that 

might need this replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replacement ................................................................. 4 work-hours × $85 per hour = $340 ........................... $20 $360 

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 proposed 

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 

We have 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 that the proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the 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 

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: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing airworthiness directive (AD) 

2003–19–11, Amendment 39–13314 (68 

FR 55812, September 29, 2003), and 

adding the following new AD: 

Learjet Inc.: Docket No. FAA–2013–0691; 

Directorate Identifier 2012–NM–170–AD. 

(a) Comments Due Date 

The FAA must receive comments on this 

AD action by September 27, 2013. 

(b) Affected ADs 

This AD supersedes AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003). 

(c) Applicability 

This AD applies to Learjet Inc. Model 60 

airplanes, certificated in any category, serial

(d) Subject 

Joint Aircraft System Component (JASC)/ 

Air Transport Association (ATA) of America 

Code 28, Fuel. 

(e) Unsafe Condition 

This AD was prompted by reports of 

chafing of the fuel crossflow tube by flight 

control cables. We are issuing this AD to 

prevent chafing and consequent failure of the 

fuel crossflow tube due to inadequate 

clearance between the tube and the flight 

control cables, which could result in loss of 

fuel from one fuel tank during normal 

operating conditions or loss of fuel from both 

main fuel tanks during fuel cross-feeding 

operations. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Retained Part Identification 

This paragraph restates the part 

identification required by paragraph (a) of 

AD 2003–19–11, Amendment 39–13314 (68 

FR 55812, September 29, 2003). For serial 

numbers 60–001 through 60–145 inclusive: 

Within 25 flight hours after November 3, 

2003 (the effective date of AD 2003–19–11), 

inspect the fuel crossflow tube to determine 

whether part number (P/N) 6026020–005 is 

installed. Instead of inspecting the tube, a 

review of airplane maintenance records is 

acceptable if the P/N of the tube can be 

positively determined from that review. 

(h) Retained Clearance Measurement and 

Corrective Action for Airplanes Having 

Serial Numbers 60–001 Through 60–145, 

With Revised Repair Language 

This paragraph restates the clearance 

measurement and corrective action required 

by paragraph (b) of AD 2003–19–11,

language. For Learjet Inc. Model 60 airplanes, 

serial numbers 60–001 through 60–145 

inclusive: If P/N 6026020–005 is found 

installed during the review or inspection 

required by paragraph (g) of this AD, before 

further flight, measure the clearance between 

the fuel crossflow tube and the flight control 

cables to determine if it is at least 0.35 inch, 

per paragraph 2.B.(8) of the Accomplishment 

Instructions of Bombardier Alert Service 

Bulletin A60–28–3, Revision 2, dated 

October 26, 1998. 

(1) If the clearance is 0.35 inch or more, no 

further action is required by this paragraph. 

(2) If the clearance is less than 0.35 inch, 

before further flight, repair in accordance 

with a method approved by the Manager, 

Wichita Aircraft Certification Office (ACO), 

FAA. For a repair method to be approved by 

the Manager, Wichita ACO, as required by 

this paragraph, the Manager’s approval letter 

must specifically refer to this AD. 

(i) Retained Part Replacement, 

Measurement, and Repair for Airplanes 

Having Serial Numbers 60–001 Through 60– 

055, With Revised Repair Language 

This paragraph restates the clearance 

measurement and corrective action required 

by paragraph (c) of AD 2003–19–11, 

Amendment 39–13314 (68 FR 55812, 

September 29, 2003), with revised repair 

language. For airplanes having serial 

numbers 60–001 through 60–055: If P/N 

6026020–005 is not found installed during 

the review or inspection required by 

paragraph (g) of this AD, within 90 days after 

accomplishing the review or inspection, 

replace the existing fuel crossflow tube with 

a new fuel crossflow tube having P/N 

6026020–005, and measure the clearance 

between the newly installed fuel crossflow 

tube and the flight control cables, per 

paragraph 2.A. of the Accomplishment 

Instructions of Bombardier Service Bulletin 

60–28–4, Revision 2, dated August 22, 2001. 

(1) If the clearance is 0.35 inch or more, no 

further action is required by this paragraph. 

(2) If the clearance is less than 0.35 inch, 

before further flight, repair in accordance 

with a method approved by the Manager, 

Wichita ACO, FAA. For a repair method to 

be approved by the Manager, Wichita ACO, 

as required by this paragraph, the Manager’s 

approval letter must specifically refer to this 

AD. 

(j) Retained Part Replacement, 

Measurement, and Repair for Airplanes 

Having Serial Numbers 60–056 Through 60– 

145, With Revised Repair Language 

This paragraph restates the clearance 

measurement and corrective action required 

by paragraph (d) of AD 2003–19–11, 

Amendment 39–13314 (68 FR55812, 

September 29, 2003), with revised repair 

language. For airplanes having serial 

numbers 60–056 through 60–145: If P/N 

6026020–005 is not found installed during 

the review or inspection required by 

paragraph (g) of this AD, within 90 days after 

accomplishing the review or inspection, 

replace the existing fuel crossflow tube with 

a new fuel crossflow tube having P/N 

6026020–005, and measure the clearance 

between the newly installed fuel crossflow 

tube and the flight control cables to 

determine if the clearance is at least 0.35 

inch, per paragraph 2.B. of the 

Accomplishment Instructions of Bombardier 

Alert Service Bulletin A60–28–3, Revision 2, 

dated October 26, 1998. 

(1) If the clearance is 0.35 inch or more, no 

further action is required by this paragraph. 

(2) If the clearance is less than 0.35 inch, 

before further flight, repair in accordance 

with a method approved by the Manager, 

Wichita ACO, FAA. For a repair method to 

be approved by the Manager, Wichita ACO, 

as required by this paragraph, the Manager’s 

approval letter must specifically refer to this 

AD. 

Note 1 to paragraphs (h) and (j) of this AD: 

Bombardier Alert Service Bulletin A60–28–3, 

Revision 2, dated October 26, 1998, Figure 1, 

Detail D, incorrectly identifies the fuel 

crossflow tube to be installed as P/N 

6026020–001. The manufacturer is aware of 

this error and stated it plans to correct the 

part number in the next revision of the 

service information. 

(k) New Part Identification 

For airplanes having serial numbers 60– 

001 through 60–409 inclusive: Within 25 

flight hours after the effective date of this AD, 

inspect the fuel crossflow tube to determine 

whether P/N 6026020–005 is installed. In 

lieu of inspecting the tube, a review of 

airplane maintenance records is acceptable if 

the P/N of the tube can be positively 

determined from that review. 

(l) New Clearance Measurement 

If P/N 6026020–005 is found installed 

during the inspection required by paragraph 

(k) of this AD, before further flight, measure 

the clearance between the fuel crossflow tube 

and both elevator control cables to determine 

if it is 0.35 inches or more, in accordance 

with paragraph 2.A.(9) of the 

Accomplishment Instructions of Bombardier 

Optional Spares Service Bulletin 60–28–4, 

Revision 2, dated August 22, 2001. 

(1) If the clearance is 0.35 inch or more, no 

further action is required by this paragraph. 

(2) If the clearance is less than 0.35 inch, 

before further flight, adjust the fit of the 

P/N 6026020–005 tube to provide 0.35 inch 

or more clearance to both elevator control 

cables, in accordance with paragraph 2.A.(9) 

of the Accomplishment Instructions of 

Bombardier Optional Spares Service Bulletin 

60–28–4, Revision 2, dated August 22, 2001. 

If the tube shows any indication of chafing 

from the control cables, before further flight, 

replace the fuel cross flow tube with a new 

fuel cross flow tube, in accordance with 

paragraph 2.A.(9) of the Accomplishment 

Instructions of Bombardier Optional Spares 

Service Bulletin 60–28–4, Revision 2, dated 

August 22, 2001. 

(m) New Repetitive Measurements 

For all airplanes: As of the effective date 

of this AD and after accomplishing the 

inspection required by paragraph (g) or (k) of 

this AD, as applicable: Before further flight 

after removal, replacement, or adjustment of 

any crossflow tube, fuel cross flow drain 

valve, fuel cross flow valve or related 

plumbing and fittings, and elevator control 

cable, measure the clearance between the fuel 

crossflow tube and the flight control cables, 

in accordance with paragraph 2.A.(9) of the 

Accomplishment Instructions of Bombardier 

Optional Spares Service Bulletin 60–28–4, 

Revision 2, dated August 22, 2001. 

(1) If the clearance is 0.35 inch or more, no 

further action is required by this paragraph. 

(2) If the clearance is less than 0.35 inch, 

before further flight, adjust the fit of the

Identifier 2012–NM–221–AD]

Airworthiness Directives; EADS CASA 

(Type Certificate Previously Held by 

Construcciones Aerona ́uticas, S.A.) 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

EADS CASA (Type Certificate 

Previously Held by Construcciones 

Aerona ́uticas, S.A.) Model C–212–CB, 

C–212–CC, C–212–CD, C–212–CE, and 

C–212–DF airplanes. This proposed AD 

was prompted by a report of the 

propeller pitch control (PPC) lever 

becoming disconnected from the engine 

due to a missing bolt. This proposed AD 

would require modifying the PPC lever 

attachment system. We are proposing 

this AD to prevent PPC shaft 

disconnection, which could lead to a 

loss of propeller pitch control, possibly 

resulting in uncommanded change to 

the engine power settings and 

consequent reduced controllability of 

the airplane. 

DATES: We must receive comments on 

this proposed AD by September 27, 

2013.

any of the following methods:
