Airworthiness Directives; Learjet Inc. 

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 

Learjet Inc. Model 45 airplanes. This 

proposed AD was prompted by reports 

of non-conforming windshield supports 

(coupe rails). This proposed AD would 

require a general visual inspection to 

detect gouging and scratches and to 

determine if a radius has been removed; 

an ultrasound inspection to measure the 

dimensions of the lower coupe rails; an 

eddy current inspection to detect cracks 

of the lower coupe rails; replacement of 

the lower coupe rails if necessary; and 

revision of the maintenance or 

inspection program, as applicable. We 

are proposing this AD to detect and 

correct non-conforming windshield 

supports, which could result in 

uncontrolled cabin depressurization. 

Non-conforming windshield supports 

could also compromise the capability of 

the windshield to withstand a bird 

strike. 

DATES: We must receive comments on 

this proposed AD by June 2, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2014–0249; Directorate Identifier 2012– 

NM–211–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed 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 proposed AD. 

Discussion 

We received reports of nonconforming windshield supports (coupe 

rails). Learjet Inc. identified windshield 

primary supports that do not meet their 

type design. The non-conforming 

windshield supports (coupe rails) might 

have been compromised during fuselage 

build or windshield installation. This 

condition, if not corrected, could result 

in uncontrolled cabin depressurization. 

Non-conforming windshield supports 

could also compromise the capability of 

the windshield to withstand a bird 

strike. 

Relevant Service Information 

We reviewed the following service 

information. The service information 

describe procedures for a detailed visual 

inspection to detect gouging and 

scratches and to determine if a radius 

has been removed; an ultrasound 

inspection to measure the dimensions of 

the lower coupe rails; an eddy current 

inspection to detect cracks of the lower 

coupe rails, replacement of the lower 

coupe rails if necessary; and revision of 

the maintenance or inspection program, 

as applicable.

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 these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 351 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 


pmangrum on DSK3VPTVN1PROD with PROPOSALS-1
Federal Register / Vol. 79, No. 73 / Wednesday, April 16, 2014 / Proposed Rules 21417 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Inspection .......................... 40 work-hours × $85 per 

hour = $3,400 per inspection cycle.

$77 .................................... $3,477 per inspection 

cycle.

$1,220,427 per inspection 

cycle 

Maintenance or inspection 

program revision.

1 work hour × $85 per 

hour = $85.

None .................................. $85 .................................... $29,835 

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 .................................. 500 work-hours (to replace both 

coupe rails) × $85 per hour = 

$42,500.

$15,000 (to replace both coupe 

rails).

$57,500 (to replace both coupe 

rails) 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all costs in our 

cost estimate. 

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 

products identified in this rulemaking 

action. 

Regulatory Findings 

We 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) 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.
