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.

Note 2: Raytheon Model DH 125–1B, –3B,

and –400B series airplanes are similar in

design to the airplanes that are subject to the

requirements of this AD and, therefore, also

may be subject to the unsafe condition

addressed by this AD. However, as of the

effective date of this AD, those models are

not type certificated for operation in the

United States. Airworthiness authorities of

countries in which the Model DH 125–1B,

–3B, and –400B series airplanes are approved

for operation should consider adopting

corrective action, applicable to those models,

that is similar to the corrective action

required by this AD.

Compliance: Required as indicated, unless

accomplished previously.

To detect and correct scoring of the upper

fuselage skin around the periphery of the

cockpit canopy blister interface, which could

result in reduced structural integrity of the

fuselage skin, and consequent cabin

depressurization; accomplish the following:

(a) Within 90 days after the effective date

of this AD, perform a one-time detailed

visual inspection to detect scoring of the

upper fuselage skin around the periphery of

the cockpit canopy blister interface, in

accordance with Raytheon Service Bulletin

SB.53–93, dated May 16, 1996.

(b) If no scoring is detected during the

inspection required by paragraph (a) of this

AD, no further action is required by this AD.

(c) If any scoring is detected during the

inspection required by paragraph (a) of this

AD, prior to further flight, determine the

maximum location and details of each score,

including the edge distance and material

thickness, in accordance with Service

Bulletin SB.53–93, dated May 16, 1996.

(1) If any scoring is found that is within the

limits specified in the service bulletin, prior

to further flight, repair in accordance with

the service bulletin.

(2) If any scoring is found that is outside

the limits specified in the service bulletin,

prior to further flight, repair in accordance

with a method approved by the Manager,

Wichita Aircraft Certification Office (ACO),

FAA, Small Airplane Directorate.

(d) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager, Wichita

ACO. Operators shall submit their requests

through an appropriate FAA Principal

Maintenance Inspector, who may add

comments and then send it to the Manager,

Wichita ACO.

Note 3: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Wichita ACO.

(e) 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.

AGENCY: Federal Aviation

Administration [FAA], DOT.

ACTION: Proposed rule, withdrawal.

SUMMARY: This action withdraws the

Notice of Proposed Rulemaking (NPRM)

which proposed to change the Class E

airspace area at Muscatine, IA. The

NPRM is being withdrawn due to the

delay in the installation of the Port City

Very High Frequency Omnidirectional

Range/Distance Measuring Equipment

(VOR/DME).

SUPPLEMENTARY INFORMATION:

The Proposed Rule

On December 20, 1995 (60 FR 65601),

a Notice of Proposed Rulemaking was

published in the Federal Register to

change the Class E airspace at

Muscatine, IA. The delay in obtaining

the necessary equipment has resulted in

delaying the installation and

commissioning of the VOR/DME until

late 1997 or early 1998.

Conclusion

In consideration of the

aforementioned delay in installation

and commissioning of the Port City

VOR/DME, action is being taken to

withdraw the proposed amendment of

the Class E airspace area at Muscatine,

IA. If necessary, a new NPRM will be

prepared at a later date.
