Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Proposed Rules
(e) Reason
This AD was prompted by mandatory
continuing airworthiness information (MCAI)
originated by an aviation authority of another
country to identify and correct an unsafe
condition on an aviation product. The MCAI
describes the unsafe condition as missing
countersunk washers under the head of the
main landing gear (MLG) trunnion cap
tension bolts that could cause fatigue in the
bolt shanks. We are issuing this AD to detect
and correct missing countersunk washers,
which could lead to failure of the bolt(s),
thereby compromising the structural integrity
of the other MLG tension bolts holding the
MLG in place, possibly resulting in collapse
of the MLG on take-off or landing with
consequent damage to the airplane and injury
to occupants.
(f) Actions and Compliance
Unless already done, do the actions in
paragraphs (f)(1) through (f)(4) of this AD,
including all subparagraphs, following the
Accomplishment Instructions in British
Aerospace Jetstream Series 3100 & 3200
Service Bulletin 57–JA120141, REVISION 1,
dated April 8, 2014:
(1) This AD allows credit for the actions
required in paragraphs (f)(3) and (f)(4),
including all subparagraphs, of this AD if
done before the effective date of this AD
following the Accomplishment Instructions
of British Aerospace Jetstream Series 3100 &
3200 Service Bulletin 57–JA120141, Original
Issue, dated: July 31, 2012.
(2) For the purposes of this AD, owner/
operators who do not track total flight cycles
(FC), multiply the total number of airplane
hours time-in-service by 0.75 to calculate the
FC.
(3) For Pre-Mod JM5218 airplanes: Within
250 FC after the effective date of this AD, do
a magnetic particle inspection (MPI) of each
MLG trunnion cap tension bolt.
(i) If no crack is found during the MPI
required by paragraph (f)(1) of this AD, before
further flight, either re-install the crack-free
bolt(s) or install a replacement bolt(s) having
the same part number (P/N) as the original
bolt. Install a countersunk washer under the
bolt(s) ensuring the washer P/N is applicable
to the diameter bolt installed as specified in
figure 1 of paragraph (f)(3)(i) of this AD.

PKS1000–7–2–S
(washer).

JM5218 Replacement Parts
(ii) If a cracked bolt is found during the
inspection required by paragraph (f)(3) of this
AD, before further flight, replace each
cracked bolt with a replacement bolt having
the same P/N as the original bolt. Install a
countersunk washer under the bolt ensuring
the washer P/N is applicable to the diameter
bolt installed as specified in figure 1 of
paragraph (f)(3)(i) of this AD.
(4) For Post-Mod JM5218 airplanes:
Visually inspect each MLG trunnion cap

tension bolt to determine which type of bolt
is installed.
(i) If it is determined the installed bolts are
P/N MS21134H07045 or P/N
MS21134H07059 during the inspection
required in paragraph (f)(4) of this AD, before
further flight (except as specified in
paragraph (f)(4)(i)(A) of this AD), replace
each ‘old’ bolt P/N with a ‘new’ bolt P/N as
specified in figure 2 of paragraph (f)(4)(i) of
this AD and install a washer having P/N
PKS1000–7–2–S under each bolt.
Bolt P/N ‘Old’
Bolt P/N ‘New’

MS21134H07046, or
MS21250H07046.
MS21134H07060, or
MS21250H07060.
MS21134H07059 ......
Figure 2 of paragraph (f)(4)(i)—Post-Mod
JM5218 Replacement Parts
(A) If no ‘new’ replacement bolt is
available to comply with paragraph (f)(4)(i) of
this AD, the ‘old’ bolt may be reinstalled
without a countersunk washer, provided that
within 500 FC after reinstallation and
repetitively thereafter at intervals not to
exceed 500 FC, each affected bolt is
inspected by MPI.
(B) Within 2,000 FC after reinstallation of
a bolt as allowed by paragraph (f)(4)(i)(A) of
this AD or before further flight if a crack was
found during any MPI as required by
paragraph (f)(4)(i)(A) of this AD, whichever
occurs first, replace the ‘old’ bolt P/N with
a ‘new’ bolt P/N as specified in figure 2 of
paragraph (f)(4)(i) of this AD and install a
washer having P/N PKS1000–7–2–S under
each bolt.
(ii) If it is determined the installed bolts are
P/N MS21250H07046 or P/N
MS21250H07060 and no countersunk washer
is installed during the inspection required in
paragraph (f)(4) of this AD, before further
flight, do an MPI of each MLG trunnion cap
tension bolt.
(A) If no crack is found during the MPI
required by paragraph (f)(4)(ii) of this AD,
before further flight, either re-install the
crack-free bolts or install replacement bolts
having a ‘new’ bolt P/N as specified in figure
2 of paragraph (f)(4)(i) of this AD and install
a countersunk washer P/N PKS1000–7–2–S
under each bolt.
(B) If any crack is found during the MPI
required by paragraph (f)(4)(ii) of this AD,
before further flight, replace each cracked
bolt with a serviceable one having a ‘new’
bolt P/N as specified in figure 2 of paragraph
(f)(4)(i) of this AD and install a countersunk
washer P/N PKS1000–7–2–S under each bolt.
