Airworthiness Directives; Gulfstream

Model G–1159, G–1159A, G–1159B, G–

IV, and G–V Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; correction.

SUMMARY: This amendment corrects and

clarifies information in an existing

airworthiness directive (AD), applicable

to certain Gulfstream Model G–1159, G–

1159A, G–1159B, G–IV, and G–V series

airplanes, that currently requires an

inspection to determine if certain door

control valves of the landing gear are

installed, and modification of the valve,

if necessary. The actions specified in

that AD are intended to prevent loss of

hydraulic system fluid due to failure of

the door control valve of the landing

gear, which could require the flight

crew to use alternate gear extension

procedures (landing gear blow down)

for landing of all models. This

amendment corrects the requirements of

the current AD by specifying

appropriate alert customer bulletins for

certain airplane models, and clarifying

the compliance time for the

modification of the door control valve of

the landing gear. This amendment is

prompted by operators’ comments on

the existing AD.

DATES: Effective May 10, 2001.

The incorporation by reference of

certain publications listed in the

regulations was approved previously by

the Director of the Federal Register as of

May 10, 2001 (66 FR 20734, April 25,

2001).

SUPPLEMENTARY INFORMATION: On April

16, 2001, the Federal Aviation

Administration (FAA) issued

Airworthiness Directive (AD) 2001–08–

13, amendment 39–12191 (66 FR 20734,

April 25, 2001), which applies to certain

Gulfstream Model G–1159, G–1159A,

G–1159B, G–IV, and G–V series

airplanes. That AD requires inspection

and modification of certain door control

valves of the nose landing gear and the

main landing gear. The actions required

by that AD are intended to prevent loss

of hydraulic system fluid due to failure

of the door control valve of the landing

gear, which could require the flight

crew to use alternate gear extension

procedures (landing gear blow down)

for landing of all models.

Need for the Correction and

Clarification

Since the issuance of that AD, the

FAA has received information that

requires certain corrections and

clarifications for that AD.

In indicating which Gulfstream alert

customer bulletin to use in

accomplishing the required actions for

each of the five Gulfstream airplane

models affected, the FAA inadvertently

reversed the bulletins indicated for the

G–1159, G–1159B, and G–1159A

Gulfstream models. That information

also was included in the applicability

section in the table entitled ‘‘Gulfstream

Airplane Models and Alert Customer

Bulletins (ACB)’’ and in paragraph (b) of

AD 2001–08–13. This document

corrects the references to the

appropriate alert customer bulletins,

and will ensure that the appropriate

Gulfstream bulletin is used to

accomplish the actions required by this

AD for each of the five Gulfstream

models to which it applies.

Additionally, this document also

corrects and clarifies the compliance

time specified for the actions specified

in paragraph (b) of the AD. The FAA

inadvertently specified the compliance

times for paragraphs (b)(1) and (b)(2) of

the AD as ‘‘* * * after the effective date

of this AD.’’ We intended that the

requirements of paragraph (b) of that AD

should read ‘‘* * * after the date of

inspection accomplished per the

requirements of paragraph (a) of this

AD.’’ Correction of that wording permits

a somewhat extended compliance time

for the operators to accomplish the

requirements of paragraph (b) of this

AD. Therefore, this correction is a

relieving requirement for operators and

necessitates no additional work or cost

burdens.

Correction of the Publication

This document corrects an error,

clarifies certain requirements, and

correctly adds the AD as an amendment

to section 39.13 of the Federal Aviation

Regulations (14 CFR 39.13).

The AD is being reprinted in its

entirety for the convenience of affected

operators. The effective date of the AD

remains May 10, 2001.

Since this action only clarifies a

current requirement, it has no adverse

economic impact and imposes no

additional burden on any person.

Therefore, notice and public procedures

hereon are unnecessary.
