Discussion

The Direccio ́n Ge ́ne ́ral de l’Aviacio ́n

Civil (DGAC), which is the

airworthiness authority for Spain,

notified the FAA that an unsafe

condition may exist on all CASA Model

CN–235, CN–235–100, and CN–235–200

series airplanes. The DGAC advises that,

during fatigue testing of the Model CN–

235 series airplane, cracks were found

in the zone of the fittings connecting the

fuselage to stiffener rods located in

frame 35. Similar stiffener rods are

attached to the fuselage at frames 33 and

34. Such fatigue cracking, if not

detected and corrected, could result in

reduced structural integrity of the

airplane.

Explanation of Relevant Service

Information

CASA has issued Service Bulletin SB–

235–53–48, dated December 11, 1997,

which describes procedures for

replacing the upper brackets in frames

33, 34, and 35, with improved brackets

that are more fatigue resistant, and

reinforcing frame 35. Accomplishment

of the actions specified in the service

bulletin is intended to adequately

address the identified unsafe condition.

The DGAC classified this service

bulletin as mandatory and issued

Spanish airworthiness directive 02/

2000, dated January 31, 2000, in order

to assure the continued airworthiness of

these airplanes in Spain.

FAA’s Conclusions

This airplane model is manufactured

in Spain 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,

the DGAC has kept the FAA informed

of the situation described above. The

FAA has examined the findings of the

DGAC, reviewed all available

information, and determined that AD

action is necessary for products of this

type design that are certificated for

operation in the United States.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, the proposed AD would require

accomplishment of the actions specified

in the service bulletin described

previously.

Cost Impact

The FAA estimates that 1 airplane of

U.S. registry would be affected by this

proposed AD, that it would take

approximately 80 work hours per

airplane to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Required parts

would cost approximately $2,871 per

airplane. Based on these figures, the cost

impact of the proposed AD on the U.S.

operator of the one affected airplane is

estimated to be $7,671.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the proposed requirements of this AD

action, and that no operator would

accomplish those actions in the future if

this AD were not adopted. The cost

impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations proposed herein

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. Therefore,

it is determined that this proposal

would not have federalism implications

under Executive Order 13132.

For the reasons discussed above, I

certify that this 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); and (3) if

promulgated, 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 draft

regulatory 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
