Table 2 Serialized Structural Components Affected by LEP I and II
ATA
Structural Component
Consisting of
Pilatus P/N
Remarks
(IPC terminology)
(* = or subsequent re-
placements. The exact
P/N to be defined when
the component serial
number is known)
71
ENGINE MOUNT
Engine mount (welded)
571.20.12.036*
Only the two welded
tubular structures are
defined as LEP compo-
nent. Shockmounts ex-
cluded since they have
to be overhauled at
engine overhaul. Attach-
ment bolts excluded
since they are life limi-
ted.

Restrictions
Structural components not listed in Table 2 are not recommended to be removed from the original aircraft for use
on another aircraft since these components are not serialized parts. Parts that are not serialized cannot properly be
tracked once installed on another aircraft unless they become serialized.
On request, Pilatus may evaluate on a case-by-case basis if a non-serialized component may remain in service on
an aircraft other than the original, or be used as a spare part after 20,000 flying hours or 27,000 landings.
Certain kinds of structural components, for example non-serialized primary structural elements (frames, stringers,
fuselage skins, primary attachment fittings etc.) typically attached with rivets are not allowed to be used for
applications other than the original aircraft.

Process
The flowchart given in Fig. 1 is applicable to a single structural component that is affected by Service Bulletin
04-009 and/or the SSID and was removed from the original aircraft, but remains in service after 20,000 flying hours
or 27,000 landings on another aircraft or is a spare part. It also applies to structural components that have been
removed from an older aircraft and installed on another aircraft before 20,000 flying hours or 27,000 landings and
would become due for Service Bulletin 04-009 prior to the aircraft that it is installed on.
