§ 43.10

Disposition of life-limited air-

craft parts.

(a)

Definitions used in this section. For

the purposes of this section the fol-
lowing definitions apply.

Life-limited part means any part for

which a mandatory replacement limit
is specified in the type design, the In-
structions for Continued Airworthi-
ness, or the maintenance manual.

Life status means the accumulated

cycles, hours, or any other mandatory
replacement limit of a life-limited
part.

(b)

Temporary removal of parts from

type-certificated products. When a life-
limited part is temporarily removed
and reinstalled for the purpose of per-
forming maintenance, no disposition
under paragraph (c) of this section is
required if—

(1) The life status of the part has not

changed;

(2) The removal and reinstallation is

performed on the same serial numbered
product; and

(3) That product does not accumulate

time in service while the part is re-
moved.

(c)

Disposition of parts removed from

type-certificated products. Except as pro-
vided in paragraph (b) of this section,
after April 15, 2002 each person who re-
moves a life-limited part from a type-
certificated product must ensure that
the part is controlled using one of the
methods in this paragraph. The method
must deter the installation of the part
after it has reached its life limit. Ac-
ceptable methods include:

(1)

Record keeping system. The part

may be controlled using a record keep-
ing system that substantiates the part
number, serial number, and current life
status of the part. Each time the part
is removed from a type certificated
product, the record must be updated
with the current life status. This sys-
tem may include electronic, paper, or
other means of record keeping.

(2)

Tag or record attached to part. A

tag or other record may be attached to
the part. The tag or record must in-
clude the part number, serial number,
and current life status of the part.
Each time the part is removed from a
type certificated product, either a new
tag or record must be created, or the
existing tag or record must be updated
with the current life status.

(3)

Non-permanent marking. The part

may be legibly marked using a non-
permanent method showing its current
life status. The life status must be up-
dated each time the part is removed
from a type certificated product, or if
the mark is removed, another method
in this section may be used. The mark
must be accomplished in accordance
with the instructions under § 45.16 of
this chapter in order to maintain the
integrity of the part.

(4)

Permanent marking. The part may

be legibly marked using a permanent
method showing its current life status.
The life status must be updated each
time the part is removed from a type
certificated product. Unless the part is
permanently removed from use on type
certificated products, this permanent
mark must be accomplished in accord-
ance with the instructions under § 45.16
of this chapter in order to maintain the
integrity of the part.

§ 43.11

(5)

Segregation. The part may be seg-

regated using methods that deter its
installation on a type-certificated
product. These methods must include,
at least—

(i) Maintaining a record of the part

number, serial number, and current life
status, and

(ii) Ensuring the part is physically

stored separately from parts that are
currently eligible for installation.

(6)

Mutilation. The part may be muti-

lated to deter its installation in a type
certificated product. The mutilation
must render the part beyond repair and
incapable of being reworked to appear
to be airworthy.

(7)

Other methods. Any other method

approved or accepted by the FAA.

(d)

Transfer of life-limited parts. Each

person who removes a life-limited part
from a type certificated product and
later sells or otherwise transfers that
part must transfer with the part the
mark, tag, or other record used to com-
ply with this section, unless the part is
mutilated before it is sold or trans-
ferred.

worthiness depends, that persons must
