Airworthiness Directives; Allied Ag Cat 

Productions, Inc. Model G–164 Series 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA adopts a new 

airworthiness directive (AD) to 

supersede AD 78–08–09, which applies 

to certain Allied Ag Cat Productions, 

Inc. (formerly Grumman-American) 

(Allied Ag Cat) Models G–164, G–164A, 

and G–164B airplanes. AD 78–08–09 

currently requires repetitively 

inspecting the interior and the exterior 

of the main tubular spar of the rudder 

assembly for corrosion, taking necessary 

corrective action if corrosion is found, 

and applying corrosion protection. 

Since we issued AD 78–08–09, the 

rudder main tubular spar failed on a 

later production airplane. Consequently, 

this AD retains the actions required in 

AD 78–08–09 and expands the 

applicability to include all G–164 series 

airplanes. We are issuing this AD to 

detect and correct corrosion in the 

rudder main tubular spar, which could 

result in failure of the weld to the main 

spar tube. This failure could lead to loss 

of directional control. 

DATES: This AD becomes effective on 

December 19, 2008. 

On December 19, 2008, the Director of 

the Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

On August 1, 2008, we issued a 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an AD that would apply to 

certain Allied Ag Cat Models G–164, 

G–164A, and G–164B airplanes. This 

proposal was published in the Federal 

Register as a notice of proposed 

rulemaking (NPRM) on August 7, 2008 

(73 FR 45900). The NPRM proposed to 

supersede AD 78–08–09 with a new AD 

that would retain the actions required in 

AD 78–08–09 and expand the 

applicability to include all G–164 series 

airplanes. 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. The following presents the 

comments received on the proposal and 

FAA’s response to each comment: 

Comment Issue No. 1: AD Is Supported 

Ronald I. Gustin, Craig T. Fountain, 

and Ken J. Kuther all state that they 

support the AD action as proposed in 

the NPRM. 

Ronald Gustin states that of the 13 Ag 

Cat airplanes inspected by mechanics at 

Gustin Aviation, which was prompted 

by the NPRM, 4 airplanes had severe 

corrosion of the rudder main spar tube 

that required repair; 2 airplanes had 

light rust; and 7 airplanes were 

corrosion free. Craig T. Fountain and 

Ken J. Kuther, who collectively own 

four of the airplanes inspected by 

Gustin Aviation, confirm the reported 

corrosion found and also support the 

proposed AD action. 

The commenters support the NPRM. 

We are not changing the final rule AD 

action based on these comments. 

Comment Issue No. 2: Extend Comment 

Period 

Bryan D. Hauschild states that he is 

planning to recover the rudder on his 

airplane during the off-season, which is 

November through March. He states that 

at that time he would be able to get a 

good look at the area in question. 

Mr. Hauschild requests to extend the 

comment period for the NPRM so that 

his airplane is not pulled from its 

seasonal service at this time. 

We do not agree with the commenter. 

We believe that the fleet service history 

and severity of corrosion reported on Ag 

Cat rudders requires AD action. 

Extending the comment period in order 

to delay the effective date of this AD 


sroberts on PROD1PC70 with RULES
Federal Register / Vol. 73, No. 221 / Friday, November 14, 2008 / Rules and Regulations 67373 

would create an unacceptable safety 

risk. 

We are not changing the final rule AD 

action based on this comment. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed except for 

minor editorial corrections. We have 

determined that these minor 

corrections: 

• 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 2,700 

airplanes in the U.S. registry. 

We estimate the following costs to do 

the inspections: 

Labor cost Parts cost Total cost per 

airplane 

Total cost on 

U.S. operators 

4 work-hours × $80 per hour = $320 ........................................................ Not applicable .................................. $320 $864,000 

We have no way of determining the 

cost of repairs, parts replacement, or the 

number of airplanes that may require 

repair or parts replacement based on the 

result of the proposed inspections. 

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 AD. 

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 the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. 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. 

We prepared a summary of the costs 

to comply with this AD (and other 

information as included in the 

Regulatory Evaluation) and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2008–0854; 

Directorate Identifier 2008–CE–050– 

AD’’ in your request.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the Federal Aviation Administration 

amends part 39 of the Federal Aviation 

Regulations (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) 

78–08–09, Amendment 39–3191, and 

adding the following new AD: 

2008–22–21 Allied Ag Cat Productions, 

Inc.: Amendment 39–15718; Docket No. 

FAA–2008–0854; Directorate Identifier 

2008–CE–050–AD. 

Effective Date 

(a) This AD becomes effective on December 

19, 2008. 

Affected ADs 

(b) This AD supersedes AD 78–08–09, 

Amendment 39–3191. 

Applicability 

(c) This AD applies to the following 

airplane models, all serial numbers, that are 

certificated in any category: 

Models 

G–164, G–164A, G–164B, G–164B with 73’’ 

wing gap, G–164B–15T, G–164B–34T, G– 

164B–20T, G–164C, G–164D, and G– 

164D with 73’’ wing gap. 

Unsafe Condition 

(d) This AD results from a report of the 

rudder main tubular spar failing on a later 

production airplane. We are issuing this AD 

to detect and correct corrosion in the rudder 

main tubular spar, which could result in 

failure of the weld to the main spar tube. 

This failure could lead to loss of directional 

control. 

Compliance 

(e) To address this problem, you must do 

the following, unless already done: 

Actions Compliance Procedures 

(1) Drill an access hole and do a visual inspection using a borescope of the lower end internal cavity of the rudder main spar tube for 

corrosion and do a visual inspection of the 

exterior of the rudder main spar tube for corrosion.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

This Airworthiness Directive (AD) is 

issued following the discovery of a potential 

chafing between the rheostat of the 3rd crew 

member control panel reading light and the 

air gasper flexible hose, or with the electrical 

wires nearby. If le[f]t uncorrected, this 

chafing may expose the metallic spiral 

armature of the flexible hose, or damage the 

electrical wires insulation, which could 

result in a short-circuit generating sustained 

overheating and smoke emission. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

December 19, 2008. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of December 19, 2008.
