GULFSTREAM AEROSPACE CORPORATION:
Amendment 39-19311; Docket No. FAA-2018-
0104; Product Identifier 2017-CE-36-AD.
|
(a) EFFECTIVE DATE
This AD is effective July 23, 2018.
(b) AFFECTED ADS
This AD replaces AD 2015-24-06, Amendment 39-18338 (80 FR 75788,
December 4, 2015) ("AD 2015-24-06”).
(c) APPLICABILITY
This AD applies to Gulfstream Aerospace Corporation Model GVI
airplanes, serial numbers 6001 and 6003 through 6163, certificated in
any category.
NOTE 1 TO PARAGRAPH (C) OF THIS AD: Model GVI airplanes are also ref-
erred to by the marketing designations G650 and G650ER.
(d) SUBJECT
Joint Aircraft System Component (JASC)/Air Transport Association (ATA)
of America Code 32, Landing Gear.
(e) UNSAFE CONDITION
AD 2015-24-06 was prompted by reports of the main landing gear (MLG)
self-sealing couplings on the MLG brake inlet fitting backing out of
the fully seated position. This AD was prompted by the development of
modifications that when incorporated would terminate the need for
repetitive breakaway torque checks and torqueing of the brake inlet
self-sealing couplings. We are issuing this AD to prevent loss of
braking capability on one or multiple brakes. The unsafe condition, if
not addressed, could lead to runway overrun or asymmetrical braking
that could result in lateral runway excursion.
(f) COMPLIANCE
Comply with this AD within the compliance times specified, unless
already done.
(g) MODIFICATION OF THE MLG AND MLG BRAKE ASSEMBLIES
(1) Within 6 months after July 23, 2018 (the effective date of this AD),
modify the MLG and brake assemblies following the Accomplishment
Instructions in Gulfstream G650 Customer Bulletin Number 155B, dated
July 26, 2017; and Gulfstream G650ER Customer Bulletin Number 155B,
dated July 26, 2017.
(2) Although Gulfstream G650 Customer Bulletin Number 155B, dated July 26,
2017; and Gulfstream G650ER Customer Bulletin Number 155B, dated July
26, 2017, both contain reporting requirements and return of certain
parts to the manufacturer, this AD does not include those
requirements.
(3) AD 2015-24-06 required a dispatch and takeoff limitation in the air-
plane flight manual. Although we did not retain that requirement in
this AD, if not already removed, this limitation should be removed
after the modification in paragraph (g)(1) of this AD is done.
(h) CREDIT FOR PREVIOUS ACTIONS
If done before July 23, 2018 (the effective date of this AD), this AD
allows credit for the actions in paragraph (g) of this AD following
Gulfstream G650 Customer Bulletin 155, dated July 29, 2016; Gulfstream
G650ER Customer Bulletin 155, dated July 29, 2016; Gulfstream G650
Customer Bulletin 155A, dated August 19, 2016; or Gulfstream G650ER
Customer Bulletin 155A, dated August 19, 2016, as applicable.
(i) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS)
(1) The Manager, Atlanta ACO Branch, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19. In accordance with 14 CFR 39.19, send your request to your
principal inspector or local Flight Standards District Office, as
appropriate. If sending information directly to the manager of the
certification office, send it to the attention of the person
identified in paragraph (j) of this AD.
(2) Before using any approved AMOC, notify your appropriate principal
inspector, or lacking a principal inspector, the manager of the local
flight standards district office/certificate holding district office.
(3) For service information that contains steps that are labeled as
Required for Compliance (RC), the provisions of paragraphs (i)(3)(i)
and (ii) of this AD apply.
(i) The steps labeled as RC, including substeps under an RC step and any
figures identified in an RC step, must be done to comply with the AD.
An AMOC is required for any deviations to RC steps, including substeps
and identified figures.
(ii) Steps not labeled as RC may be deviated from using accepted methods
in accordance with the operator's maintenance or inspection program
without obtaining approval of an AMOC, provided the RC steps,
including substeps and identified figures, can still be done as
specified, and the airplane can be put back in an airworthy
condition.
