37314 Federal Register / Vol. 65, No. 115 / Wednesday, June 14, 2000 / Proposed Rules

Regulatory Impact

Since this action only withdraws a

notice of proposed rulemaking, it is

neither a proposed nor a final rule and

therefore is not covered under Executive

Order 12866, the Regulatory Flexibility

Act, or DOT Regulatory Policies and

Procedures (44 FR 11034, February 26,

1979).

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation

safety, Safety.

The Withdrawal

Accordingly, the notice of proposed

rulemaking, Docket 92–NM–206–AD,

published in the Federal Register on

April 9, 1993 (58 FR 18347), is

withdrawn.

Issued in Renton, Washington, on June 7,

2000.

Airworthiness Directives; Gulfstream

G–1159 (G–II), G–1159A (G–III), and G–

1159B (G–IIB) Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Proposed rule; withdrawal.

SUMMARY: This action withdraws a

notice of proposed rulemaking (NPRM)

that proposed a new airworthiness

directive (AD), applicable to all

Gulfstream G–1159 (G–II), G–1159A (G–

III), and G–1159B (G–IIB) series

airplanes. That action would have

required a one-time inspection to detect

corrosion of the material layers of the

lower aft fuselage skin in Fuselage

Station (FS) 580 bulkhead assembly,

and repair, if necessary. The proposal

also would have required modification

of the aft fuselage area and various

follow-on actions. Since the issuance of

the NPRM, the Federal Aviation

Administration (FAA) has received new

data from the manufacturer verifying

that all airplanes have accomplished

those actions. Accordingly, the

proposed rule is withdrawn.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

add a new airworthiness directive (AD),

applicable to all Gulfstream G–1159 (G–

II), G–1159A (G–III), and G–1159B (G–

IIB) series airplanes, was published in

the Federal Register as a Notice of

Proposed Rulemaking (NPRM) on June

24, 1996 (61 FR 32369). The proposed

rule would have required a one-time

inspection to detect corrosion of the

material layers of the lower aft fuselage

skin in Fuselage Station (FS) 580

bulkhead assembly, and repair, if

necessary. The proposal also would

have required modification of the aft

fuselage area and various follow-on

actions. That action was prompted by

reports of varying levels of corrosion in

the structure at FS 580. The proposed

actions were intended to prevent the

retention of moisture in the fuselage

structure, and subsequent corrosion in

FS 580 bulkhead assembly, which could

result in reduced structural capability of

the skin joint and resultant

depressurization of the airplane.

Actions That Occurred Since the NPRM

Was Issued

Since the issuance of that NPRM,

Gulfstream has provided evidence to the

FAA that the actions proposed in the

NPRM have been accomplished on all

affected airplanes. (Evidence was

provided to the FAA in Gulfstream’s

letter of May 30, 2000, which is filed in

the Rules Docket.)

FAA’s Conclusions

Upon further consideration, the FAA

has determined that the unsafe

condition no longer exists on the subject

airplanes. Accordingly, the proposed

rule is hereby withdrawn.

Withdrawal of this notice of proposed

rulemaking constitutes only such action,

and does not preclude the agency from

issuing another notice in the future, nor

does it commit the agency to any course

of action in the future.

Regulatory Impact

Since this action only withdraws a

notice of proposed rulemaking, it is

neither a proposed nor a final rule and

therefore is not covered under Executive

Order 12866, the Regulatory Flexibility

Act, or DOT Regulatory Policies and

Procedures (44 FR 11034, February 26,

1979).

SUMMARY: This action withdraws a

that proposed a new airworthiness

directive (AD), applicable to all

Gulfstream Model G–1159 (G–II), G–

1159A (G–III), and G–1159B (G–IIB)

required inspections to detect cracking

and/or corrosion at various locations of

the wings, and modification of cracked

and/or corroded parts. Since the

issuance of the NPRM, the Federal

Aviation Administration (FAA) has

received new data verifying that all

affected airplanes have complied with

the requirements proposed by that

NPRM. Accordingly, the proposed rule

is withdrawn.
