GULFSTREAM AEROSPACE CORPORATION:
( c o r r e c t i o n ) Amendment 39-19260; Docket No. FAA-2017-1163; Product Identifier 2017-CE-041-AD. |
TDATA NOTE:The FAA is correcting typos that incorrectly reference Customer
Bulletin 238A as Customer Bulletin 283A. In all other respects,
the original document remains the same.
(a) EFFECTIVE DATE
This AD is effective June 11, 2018.
(b) AFFECTED ADS
None.
(c) APPLICABILITY
This AD applies to the following Gulfstream Aerospace Corporation
model airplanes that are certificated in any category:
(1) Model G-IV, serial numbers (S/Ns) 1000 through 1399 having Aircraft
Service Change (ASC) 416A (MSG-3) incorporated; and S/Ns 1400 through
1535; and
(2) Model GIV-X, S/Ns 4001 through 4355.
(d) SUBJECT
Joint Aircraft System Component (JASC)/Air Transport Association (ATA)
of America Code 32, Landing Gear.
(e) UNSAFE CONDITION
This AD was prompted by the potential for fatigue cracks in the main
landing gear (MLG) actuator attachment fitting that had a certain
repair incorporated. We are issuing this AD to prevent failure of the
MLG actuator attachment. The unsafe condition, if not addressed, could
compromise the lateral support of the MLG during ground maneuvers,
possibly leading to collapse of the affected MLG with consequent loss
of control. In addition, this condition could also cause the MLG side
brace to fail, which could result in a penetration of the wing fuel
tank causing an uncontained fire.
(f) COMPLIANCE
At whichever of the following in paragraphs (f)(1) and (f)(2) that
occurs later, comply with the actions in paragraphs (g) through (i) of
this AD, unless already done.
(1) Within the next 100 hours time-in-service after June 11, 2018 (the
effective date of this AD); or
(2) Within the next 3 months after June 11, 2018 (the effective date of
this AD).
(g) INSPECT MAINTENANCE RECORDS
Inspect the airplane maintenance records to determine if repair
SE05732102 for the MLG side brace fitting has been incorporated. To do
this inspection, use the Accomplishment Instructions in Gulfstream
G350 Customer Bulletin Number 192A; Gulfstream G450 Customer Bulletin
192A; Gulfstream IV Customer Bulletin Number 238A; Gulfstream G300
Customer Bulletin Number 238A; and Gulfstream G400 Customer Bulletin
Number 238A; all dated June 15, 2017, as applicable. The service
information referenced in this paragraph specifies sending a service
reply card back to Gulfstream Aerospace Corporation if repair
SE05732102 for the MLG side brace fitting has been not been
incorporated. This action is not required in this AD.
(h) DETERMINE INITIAL AND REPETITIVE INSPECTION REQUIREMENTS
If it is determined during the maintenance records inspection required
in paragraph (g) of this AD that repair SE05732102 for the MLG side
brace fitting has been incorporated, determine the initial and
repetitive inspection requirements using the Accomplishment
Instructions of the service information identified in paragraph (g) of
this AD along with the following documents, as applicable. Comply with
