AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Gippsland Aeronautics Pty. Ltd. 

(Gippsland) Model GA8 airplanes. This 

AD requires you to repetitively inspect 

the upper and lower grooves of the 

forward cargo door slide for cracks, 

excessive wear, and excessive width. 

This AD also requires you to replace the 

forward cargo door slide if any of the 

above conditions are found during any 

inspection. This AD results from 

mandatory continuing airworthiness 

information (MCAI) issued by the 

airworthiness authority for Australia. 

We are issuing this AD to prevent 

failure of the forward cargo door slide 

caused by cracks, excessive wear, or 

excessive width. This failure could 

result in the cargo door detaching from 

the airplane in flight, potentially 

causing damage by hitting the back end 

of the airplane. 

DATES: This AD becomes effective on 

November 17, 2005. 

As of November 17, 2005, the Director 

of the Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulation. 

We must receive any comments on 

this AD by November 25, 2005.

SUPPLEMENTARY INFORMATION: 

Discussion 

What events have caused this AD? 

The Civil Aviation Safety Authority 

(CASA), which is the airworthiness 

authority for Australia, recently notified 

FAA that an unsafe condition may exist 

on all Gippsland Model GA8 airplanes. 

The CASA reports that excessive wear 

in the slide of the forward cargo door 

was found during a routine inspection. 

What is the potential impact if FAA 

took no action? If not prevented, cracks, 

excessive wear, or excessive width in 

the forward cargo door slide could cause 

the door slide to fail. This failure could 

result in the cargo door detaching from 

the airplane in flight, potentially 

causing damage by hitting the back end 

of the airplane. 

Is there service information that 

applies to this subject? Gippsland has 

issued Mandatory Service Bulletin No. 

SB–GA8–2005–23, Issue 2, dated 

September 13, 2005. 

What are the provisions of this service 

information? The service bulletin 

specifies repetitively inspecting the 

forward cargo door slide for cracks, 

signs of excessive wear, and excessive 

width. The service bulletin also 

specifies replacing the forward cargo 

door slide with a new cargo door slide, 

part number GA8–521022–149, if any of 

the above conditions are found during 

any inspection. 

What action did the CASA take? The 

CASA classified this service bulletin as 

mandatory and issued Australian AD 

Number AD/GA8/3, dated September 

27, 2005, to ensure the continued 

airworthiness of these airplanes in 

Australia. 

Did the CASA inform the United 

States under the bilateral airworthiness 

agreement? These Gippsland Model 

GA8 airplanes are manufactured in 

Australia and are type-certificated for 

operation in the United States under the 

provisions of section 21.29 of the 

Federal Aviation Regulations (14 CFR 

21.29) and the applicable bilateral 

airworthiness agreement. 

Under this bilateral airworthiness 

agreement, the CASA has kept us 

informed of the situation described 

above. 

FAA’s Determination and Requirements 

of This AD 

What has FAA decided? We have 

examined the CASA’s findings, 

reviewed all available information, and 

determined that we need to issue an AD 

for products of this type design that are 

certificated for operation in the United 

States. 

Since the unsafe condition described 

previously is likely to exist or develop 

on other Gippsland Model GA8 

airplanes of the same type design that 

are registered in the United States, we 

are issuing this AD to prevent failure of 

the forward cargo door slide caused by 

cracks, excessive wear, or excessive 

width. This failure could result in the 

cargo door detaching from the airplane 

in flight, potentially causing damage by 

hitting the back end of the airplane. 

What does this AD require? This AD 

requires you to repetitively inspect the 

upper and lower grooves of the forward 

cargo door slide for cracks, excessive 

wear, and excessive width. This AD also 

requires you to replace the forward 

cargo door slide if any of the above 

61548 Federal Register / Vol. 70, No. 205 / Tuesday, October 25, 2005 / Rules and Regulations 

conditions are found during any 

inspection. 

In preparing this rule, we contacted 

type clubs and aircraft operators to get 

technical information and information 

on operational and economic impacts. 

We did not receive any information 

through these contacts. If received, we 

would have included a discussion of 

any information that may have 

influenced this action in the rulemaking 

docket. 

How does the revision to 14 CFR part 

39 affect this AD? On July 10, 2002, we 

published a new version of 14 CFR part 

39 (67 FR 47997, July 22, 2002), which 

governs FAA’s AD system. This 

regulation now includes material that 

relates to altered products, special flight 

permits, and alternative methods of 

compliance. This material previously 

was included in each individual AD. 

Since this material is included in 14 

CFR part 39, we will not include it in 

future AD actions. 

Comments Invited 

Will I have the opportunity to 

comment before you issue the rule? This 

AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment; 

however, we invite you to submit any 

written relevant data, views, or 

arguments regarding this AD. Send your 

comments to an address listed under 

ADDRESSES. Include the docket number, 

‘‘FAA–2005–22639; Directorate 

Identifier 2005–CE–48–AD’’ at the 

beginning of your comments. We will 

post all comments we receive, without 

change, to http://dms.dot.gov, including 

any personal information you provide. 

We will also post a report summarizing 

each substantive verbal contact with 

FAA personnel concerning this AD. 

Using the search function of our 

docket Web site, anyone can find and 

read the comments received into any of 

our dockets, including the name of the 

individual who sent the comment (or 

signed the comment on behalf of an 

association, business, labor union, etc.). 

This is docket number FAA–2005–

22639; Directorate Identifier 2005–CE–

48–AD. You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11,

Are there any specific portions of this 

AD I should pay attention to? We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. If you contact us through a 

nonwritten communication and that 

contact relates to a substantive part of 

this AD, we will summarize the contact 

and place the summary in the docket.

Authority for This Rulemaking 

What authority does FAA have for 

issuing this rulemaking action? 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 

Will this AD impact various entities? 

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. 

Will this AD involve a significant rule 

or regulatory action? 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–2005–22639; 

Directorate Identifier 2005–CE–48–AD’’

in your request.

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed airworthiness directive (AD). 

The proposed AD applies to Rolls-Royce 

Corporation (RRC) (formerly Allison 

Engine Company) 501–D22A, 501–

D22C, and 501–D22G turboprop 

engines. We published the proposed AD 

in the Federal Register on March 29, 

2005 (70 FR 15784). That action 

proposed to require a onetime 

inspection for proper metal hardness of 

certain 1st stage, 2nd stage, 3rd stage, 

and 4th stage turbine wheels. That 

action proposed to do the inspection at 

the next shop visit of the engine or 

turbine module, but not to exceed 7,400 

cycles-since-new of any 1st stage, 2nd 

stage, 3rd stage, or 4th stage turbine 

wheel.
