The incorporation by reference of Airbus

All Operator Telex (AOT) 27–14, dated

November 3, 1993, was approved previously

by the Director of the Federal Register, in

accordance with 5 U.S.C. 552(a) and 1 CFR

part 51, as of January 29, 1994 (59 FR 507,

January 5, 1994). The incorporation by

reference of Airbus Service Bulletin A300–

27–6025, dated September 15, 1993, was

approved previously by the Director of the

Federal Register, in accordance with 5 U.S.C.

552(a) and 1 CFR part 51, as of May 20, 1994

(59 FR 23133, May 5, 1994). The

incorporation by reference of the other

service bulletins, listed above, was approved

by the Director of the Federal Register in

accordance with 5 U.S.C. 552(a) and 1 CFR

part 51. Copies may be obtained from Airbus

Industrie, 1 Rond Point Maurice Bellonte,

31707 Blagnac Cedex, France. Copies may be

inspected at the FAA, Transport Airplane

Directorate, 1601 Lind Avenue, SW., Renton,

Washington; or at the Office of the Federal

Register, 800 North Capitol Street, NW., suite

Airworthiness Directives; Brackett

Aircraft Company, Inc. Air Filter

Assemblies Installed on Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This document supersedes

airworthiness directive (AD) 95–03–02,

which currently requires repetitively

inspecting (visually) the air filter frame

for a loose or deteriorating gasket on

airplanes incorporating certain Brackett

air filter assemblies and replacing any

gasket found loose or deteriorated. This

action requires retaining the repetitive

inspection as contained in AD 95–03–

02, and will incorporate additional

Brackett air filter assemblies to the

‘‘Applicability’’ section of that AD.

Additionally, this AD will provide a

terminating action for the repetitive

inspection. The Federal Aviation

Administration’s determination that

certain additional Bracket air filter

assemblies should be inspected and

replaced prompted this AD action. The

actions specified by this AD are

intended to prevent gasket particles

from entering the carburetor because of

air filter gasket failure, which could

result in partial or complete loss of

engine power and loss of control of the

airplane.

DATES: Effective June 7, 1996.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of June 7,

1996.

ADDRESSES: Service information that

applies to this AD may be obtained from

(FAA), Central Region, Office of the

Assistant Chief Counsel, Attention:

Rules Docket 95–CE–61–AD, Room

1558, 601 E. 12th Street, Kansas City,

Missouri, 64106; or at the Office of the

Federal Register, 800 North Capitol

Street, NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an AD that would apply to

airplanes incorporating certain Brackett

air filter assemblies was published in

the Federal Register on December 18,

1995 (60 FR 65038). This action would

retain the requirement to repetitively

inspect (visually) the air filter for a loose

or deteriorated gasket and replacing any

gasket found loose or deteriorated as

contained in AD 95–03–02, and would

incorporate additional Brackett air filter

assemblies in the ‘‘Applicability’’

section of that AD. Additionally, this

proposed AD would provide a

terminating action for the repetitive

inspection by replacing any gasket

found loose or deteriorated with a

gasket of improved design.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were received on the

proposed rule or the FAA’s

determination of the cost to the public.

After careful review of all available

information related to the subject

presented above, the FAA has

determined that air safety and the

public interest require the adoption of

the rule as proposed except for minor

editorial corrections. The FAA has

determined that these minor corrections

will not change the meaning of the AD

and will not add any additional burden

upon the public than was already

proposed.

The FAA estimates that 50,000

airplanes in the U.S. registry will be

affected by this AD. To accomplish this

repetitive inspection and possible

replacement of a damaged air filter will

take approximately 1 hour per airplane

for each task, and that the average labor

rate is approximately $60 an hour. The

air filter assembly replacement is

estimated to be $40 per airplane. The
18668 Federal Register / Vol. 61, No. 83 / Monday, April 29, 1996 / Rules and Regulations

total estimated cost for this modification

required at 500 hours TIS will be $100

per airplane and the total cost impact of

the modification is estimated to be

$5,000,000. The FAA knows that each

owner/operator will have to repetitively

inspect a maximum of four times before

the mandatory replacement of the air

filter assembly, and based on the

assumption that no operator will

incorporate the modification prior to the

500 hours TIS, the total cost of four

repetitive inspections will be $240 per

airplane plus the cost of the terminating

action. Based on these figures the total

cost impact of this AD on U.S. operators

is estimated to be $17,000,000.

The regulations adopted herein will

not have substantial direct effects 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. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (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)

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. A copy of the final

evaluation prepared for this action is

contained in the Rules Docket. A copy

of it may be obtained by contacting the

Rules Docket at the location provided

under the caption ADDRESSES.

To prevent gasket particles from entering

the carburetor because of air filter gasket

failure, which could result in partial or

complete loss of engine power, accomplish

the following:

(a) Inspect (visually) the inside and outside

of the air filter frame for gasket looseness,

movement, or deterioration in accordance

with Brackett Document I–194, dated March

16, 1994. Continue this repetitive inspection

at intervals not to exceed 100 hours TIS, until

accomplishment of the terminating action

required in paragraph (c) of this AD.

(b) If the gasket is found to be damaged,

prior to further flight, replace the air filter

assembly with one having a retaining lip in

accordance with the Brackett

INSTALLATION INSTRUCTION SHEET

corresponding to the new air filter assembly

part number that is applicable to the owner/

operator’s particular model of airplane:

assembly as a terminating action to this AD

in accordance with the Brackett

INSTALLATION INSTRUCTION SHEET

corresponding to the new air filter assembly

part number that is applicable to the owner/

operator’s particular model of airplane as

specified in paragraph (b) of this AD.

(d) The replacement in paragraphs (b) and

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to Diamond Aircraft

Industries (Diamond) Model DA 20–A1

airplanes. This action requires

inspecting the aft wing cavities for

manufacturing debris, removing any

debris found, and modifying the aileron

pushrod fairings to allow them to flex.

Several reports of the aileron controls

becoming blocked because of

manufacturing debris getting jammed

between the short aileron pushrod and

the pushrod exit fairing on both left and

right wings prompted this action. The

actions specified by this AD are

intended to prevent the aileron controls

from becoming blocked causing

jamming between the short aileron

pushrod and the pushrod fairing exit,

which, if not detected and corrected,

could cause loss of control of the

airplane.

DATES: Effective May 17, 1996.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of May 17,

1996.

Comments for inclusion in the Rules

Docket must be received on or before

June 17, 1996.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Central Region,

Office of the Assistant Chief Counsel,

Attention: Rules Docket 96–CE–21–AD,

Room 1558, 601 E. 12th Street, Kansas

City, Missouri 64106.

SUPPLEMENTARY INFORMATION: Transport

Canada, which is the airworthiness

authority for Canada, recently notified

the FAA that an unsafe condition may

exist on Diamond Model DA 20–A1

airplanes. Transport Canada advises that

partial blockage of the aileron controls

because of manufacturing debris

jamming between the short aileron

pushrod and pushrod exit fairing has

occurred in several of these airplanes.

Diamond Aircraft Industries has

issued service bulletin (SB) No. DA20–

57–02, Rev. 0, Date Issued: March 7,

1996, which specifies procedures for

inspecting the inside of the wings for

debris, removing any debris, and

modifying the aileron pushrod fairings.

Transport Canada classified this

service bulletin as mandatory and

issued Emergency AD CF–96–07, dated

March 15, 1996 in order to assure the

continued airworthiness of these

airplanes in Canada.

This airplane model is manufactured

in Canada and is 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. Pursuant to

this bilateral airworthiness agreement,

Transport Canada has kept the FAA

informed of the situation described

above.

After examining the circumstances

and reviewing all available information

related to the incidents described above

including that received from Transport

Canada, the FAA has determined that

AD action should be taken in order to

prevent the aileron controls from

becoming blocked causing jamming

between the short aileron pushrod and

the pushrod fairing exit, which, if not

detected and corrected, could cause loss

of control of the airplane.

Since an unsafe condition has been

identified that is likely to exist or

develop in other Diamond Model DA

20–A1 airplanes of the same type design

registered for operation in the United

States, this AD requires visually

inspecting the aft wing cavities (both

wings) for any manufacturing debris or

foreign objects, removing any debris

found, and modifying the aileron

pushrod fairings in both wings. The

actions are to be accomplished in

accordance with the instructions in

Diamond SB No. DA20–57–02, Rev. 0,

Date Issued: March 7, 1996.

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for public prior comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in less than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting immediate flight safety and,

thus, was not preceded by notice and

opportunity to comment, comments are

invited on this rule. Interested persons

are invited to comment on this rule by

submitting such written data, views, or

arguments as they may desire.

Communications should identify the

Rules Docket number and be submitted

in triplicate to the address specified

above. All communications received on

or before the closing date for comments

will be considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before

and after the closing date for comments,

in the Rules Docket for examination by

interested persons. A report that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.
