Airworthiness Directives; CPAC, 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 all CPAC, Inc. (type 

certificate formerly held by Commander 

Aircraft Corporation, Gulfstream 

Aerospace Corporation, and Rockwell 

International) Models 112, 112B, 112TC, 

112TCA, 114, 114A, 114B, and 114TC 

airplanes. The existing AD currently 

requires a one-time inspection of the 

elevator spar for cracks and, if any crack 

is found, either replace with a 

serviceable elevator spar that is found 

free of cracks or repair/modify the 

elevator spar with an FAA-approved 

method. That AD also requires reporting 

to the FAA the results of the inspection. 

Since we issued that AD, using the data 

collected through the reporting 

requirement, we have determined there 

is a need for continued inspections. 

This proposed AD would require 

repetitive inspections of the elevator 

spar for cracks and, if any crack is 

found, either replace with a serviceable 

elevator spar that is free of any cracks 

and/or corrosion or repair/modify the 

elevator spar with an FAA-approved 

procedure. We are proposing this AD to 

correct the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by December 1, 2011. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

On March 28, 2011, we issued AD 

2011–07–13, amendment 39–16650 (76 

FR 18376, April 4, 2011), for all CPAC, 

Inc. (type certificate formerly held by 

Commander Aircraft Corporation, 

Gulfstream Aerospace Corporation, and 

Rockwell International) Models 112, 

112B, 112TC, 112TCA, 114, 114A, 114B, 

and 114TC airplanes. That AD requires 

a one-time inspection of the elevator 

spar for cracks and, if any crack is 

found, either replace with a serviceable 

elevator spar that is found free of cracks 

or repair/modify the elevator spar with 

an FAA-approved method. That AD also 

requires reporting to the FAA the results 

of the inspection. That AD was 

prompted by reports of a total of nine 

elevator spar cracks across seven of the 

affected airplanes, including a crack of 

2.35 inches just below the outboard 

hinge of the right-hand elevator. We 

issued that AD to prevent structural 

failure of the elevator spar due to such 

cracking, which could result in 

separation of the elevator from the 

airplane with consequent loss of 

control. 

Actions Since Existing AD Was Issued 

We considered AD 2011–07–13, 

amendment 39–16650 (76 FR 18376, 

April 4, 2011), an interim action while 

we evaluated the data submitted from 

the reports of the one-time inspection to 

determine if repetitive inspections are 

necessary and if a terminating action 

could be implemented. 

Since we issued AD 2011–07–13, 

amendment 39–16650 (76 FR 18376, 

April 4, 2011), using the data collected 

through the reporting requirement, we 

have determined that there is a need for 

continued repetitive inspections. 

The data indicated that approximately 

25 percent of the airplanes inspected 

have cracked elevator spars, with Model 

114 airplanes indicating almost 46 

percent of the airplanes having cracks. 

There does not appear to be a clear 

correlation between the discovery of a 

crack and hours time-in-service (TIS) on 

the airplane. 

Therefore, the data indicate that 

cracks are very prevalent and could 

appear on any airplane regardless of the 

hours TIS. Thus, we were unable to 

determine terminating action to address 

the unsafe condition. The continued 

repetitive inspections will help us 

understand the root cause of the 


rmajette on DSK29S0YB1PROD with PROPOSALS-1
Federal Register / Vol. 76, No. 200 / Monday, October 17, 2011 / Proposed Rules 64039 

cracking and develop a terminating 

action. 

Relevant Service Information 

We have included in this proposed 

AD procedures for removing the 

elevator and inspecting the forward and 

aft sides of the right-hand and left-hand 

elevator spar web at and around the 

elevator outboard hinge bracket area. 

We have approved an alternative 

method of compliance (AMOC) to AD 

2011–07–13 that offers an alternative 

method of inspection. You may find this 

AMOC at regulations.gov, Docket No. 

FAA–2011–0302 and Docket No. FAA– 

2011–1128. 

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 of 

the requirements of AD 2011–07–13, 

amendment 39–16650 (76 FR 18376, 

April 4, 2011), and make the one-time 

inspection repetitive. 

Interim Action 

We consider this proposed AD 

interim action. We continue to evaluate 

the reported data and repair procedures 

to determine a possible terminating 

action. Based on this determination, we 

may initiate further rulemaking action if 

needed to address the unsafe condition 

identified in this proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 773 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 of the elevator spar ....................... 8 work-hours × $85 per hour = $680 ............. N/A $680 $525,640 

Currently, there is no FAA-approved 

repair/modification for a cracked 

elevator spar. Further flight is 

prohibited until the repair/modification 

is submitted to the FAA and FAAapproved. Therefore, at this time, the 

FAA has no way of determining the 

costs associated with the repair/ 

modification of cracks found in the 

elevator spar. 

We estimate the following costs to do 

any 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 per elevator spar Parts cost per elevator 

spar 

Cost per product per 

elevator spar 

Replace cracked elevator spar with a serviceable elevator spar.Up to 16 work-hours × $85 per hour = $1,360 May range from $100 

to $1,000.

May range from 

$1,460 to $2,360. 

Replace cracked elevator spar with a new elevator spar.Up to 16 work-hours × $85 per hour = $1,360 $1,250 ........................ $2,610. 

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 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) 

2011–07–13, amendment 39–16650 (76 

FR 18376, April 4, 2011), and adding 

the following new AD:

Rulemaking Distribution System, which 

describes the application procedure. 

The Proposal 

The FAA is proposing an amendment 

to Title 14 Code of Federal Regulations 

(14 CFR) Part 71 by modifying Class E 

airspace at Show Low Regional Airport, 

Show Low, AZ. A minor adjustment to 

the boundary approach would be made 

for the airspace extending upward from 

1,200 feet above the surface to further 

accommodate aircraft using RNAV 

(GPS) standard instrument approach 

procedures at Show Low Regional 

Airport. This action would enhance the 

safety and management of IFR 

operations at the airport. 

Class E airspace designations are 

published in paragraph 6005, of FAA 

Order 7400.9V, dated August 9, 2011, 

and effective September 15, 2011, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document will be 

published subsequently in this Order. 

The FAA has determined this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore, this proposed regulation; (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); and (3)
