Airworthiness Directives; Gulfstream

Model G–IV 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 certain

Gulfstream Model G–IV series airplanes.

That action would have required

inspection of the data plate on the

bottom of the hydraulic brake control

module (HBCM) to verify the part and

serial numbers, and replacement of the

HBCM, if necessary. Since the issuance

of the NPRM, the Federal Aviation

Administration (FAA) has received new

data indicating that the proposed

actions have been accomplished on all

affected airplanes; therefore, the

previously identified unsafe condition

no longer exists. Accordingly, the

proposed rule is withdrawn.

(770) 703–6097.

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 certain Gulfstream Model

G–IV series airplanes, was published in

the Federal Register as a Notice of

Proposed Rulemaking (NPRM) on April

9, 1993 (58 FR 18347). The proposed

rule would have required inspection of

the data plate on the bottom of the

hydraulic brake control module (HBCM)

to verify the part and serial numbers,

and replacement of the HBCM, if

necessary. That action was prompted by

a landing incident that involved a

malfunction of the braking system. The

proposed actions were intended to

prevent a malfunction of the braking

system, which could lead to reduced

controllability of the airplane on the

ground.

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, based on this

evidence, the previously identified

unsafe condition no longer exists with

regard to the Gulfstream Model G–IV

series 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proposed rule is hereby withdrawn.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.

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.
