AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that

applies to certain Industrie

Aeronautiche e Meccaniche (I.A.M.)

Model Piaggio P–180 airplanes. This AD

requires accomplishing a leakage check

of all lavatory water tube/hose

connections, and correcting the

installation of these connections if

leakage is found. This AD is the result

of mandatory continuing airworthiness

information (MCAI) issued by the

airworthiness authority for Italy. The

actions specified by this AD are

intended to prevent water leakage from

the lavatory water duct system, which

could collect in the fuselage, freeze in

cold weather conditions, and cause the

rudder control system to jam.

DATES: Effective August 1, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of August 1,

1998.

ADDRESSES: Service information that

applies to this AD may be obtained from

I.A.M. Rinaldo Piaggio S.p.A., Via

Cibrario, 4 16154 Genoa, Italy. This

information may also be examined at

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This

AD

A proposal to amend part 39 of the

Federal Aviation Regulations (14 CFR

part 39) to include an AD that would

apply to certain I.A.M. Model Piaggio P–

180 airplanes was published in the

Federal Register as a notice of proposed

rulemaking (NPRM) on March 24, 1998

(63 FR 14049). The NPRM proposed to

require accomplishing a leakage check

of all lavatory water tube/hose

connections, and correcting the

installation of these connections if

leakage is found. Accomplishment of

the proposed action as specified in the

NPRM would be in accordance with

Piaggio Service Bulletin (Mandatory)

No. SB–80–0096, dated January 31,

1997.

The NPRM was the result of

mandatory continuing airworthiness

information (MCAI) issued by the

airworthiness authority for Italy.

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.

The FAA’s Determination

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.

Compliance Time of This AD

Although the potential of the rudder

control system to jam because of water

freezing will only be unsafe while the

airplane is in flight, this unsafe

condition is not a result of the number

of times the airplane is operated. The

chance of this situation occurring is the

same for an airplane with 10 hours timein-service (TIS) as it is for an airplane

with 500 hours TIS. For this reason, the

FAA has determined that a compliance

based on calendar time should be

utilized in this AD in order to assure

that the unsafe condition is addressed

on all airplanes in a reasonable time

period.

Cost Impact

The FAA estimates that 5 airplanes in

the U.S. registry will be affected by this

AD, that it will take approximately 2

workhours per airplane to accomplish

this action, and that the average labor

rate is approximately $60 an hour.

Based on these figures, the total cost

impact of this AD on U.S. operators is

estimated to be $600, or $120 per

airplane.

Regulatory Impact

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
Federal Register / Vol. 63, No. 118 / Friday, June 19, 1998 /Rules and Regulations 33537

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.

Adoption of the Amendment

Accordingly, pursuant to 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. Section 39.13 is amended by

adding a new airworthiness directive

(AD) to read as follows:

98–13–07 Industrie Aeronautiche E

Meccaniche: Amendment 39–10595;

Docket No. 98–CE–21–AD.

Applicability: Model Piaggio P–180

airplanes, serial numbers 1002, 1004, 1006

through 1017, 1019, and 1021 through 1030,

certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must request approval for an

alternative method of compliance in

accordance with paragraph (c) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and, if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required as indicated in the

body of this AD, unless already

accomplished.

To prevent water leakage from the lavatory

water duct system, which could collect in the

fuselage, freeze in cold weather conditions,

and cause the rudder control system to jam,

accomplish the following:

(a) Within the next 3 calendar months after

the effective date of this AD, accomplish a

leakage check of all lavatory water tube/hose

connections in accordance with the

ACCOMPLISHMENT INSTRUCTIONS

section of Piaggio Service Bulletin

(Mandatory) No. SB–80–0096, dated January

31, 1997. If leakage is found, prior to further

flight, correct the installation of these

connections in accordance with the abovereferenced service bulletin.

Note 2: Although not required by this AD,

the FAA recommends an inspection of the

rudder cables for corrosion if any evidence of

water is found on the cables.

(b) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

(c) An alternative method of compliance or

adjustment of the compliance times that

provides an equivalent level of safety may be

approved by the Manager, Small Airplane

Directorate, 1201 Walnut, suite 900, Kansas

City, Missouri 64106. The request shall be

forwarded through an appropriate FAA

Maintenance Inspector, who may add

comments and then send it to the Manager,

Small Airplane Directorate.

Gliders

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that

applies to certain Glaser-Dirks

Flugzeugbau GmbH (Glaser-Dirks)

Model DG–400 gliders. This AD requires

replacing the bungees that secure the

left engine restraining cable and the

bowden cable of the rear engine door.

This AD is the result of mandatory

continuing airworthiness information

(MCAI) issued by the airworthiness

authority for Germany. The actions

specified by this AD are intended to

prevent the engine from locking in flight

and not extending because of the left

restraining cable or bowden cable of the

rear door making contact with the

engine, which could result in loss of

glider power and potential loss of

control.

DATES: Effective August 2, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of August 2,

1998.
