§ 121.1115 Limit of validity.
(a)
Applicability.
This section applies
to certificate holders operating any
transport category, turbine-powered
airplane with a maximum takeoff gross
weight greater than 75,000 pounds and a
type certificate issued after January 1,
1958, regardless of whether the max-
imum takeoff gross weight is a result
of an original type certificate or a
later design change. This section also
applies to certificate holders operating
any transport category, turbine-pow-
ered airplane with a type certificate
issued after January 1, 1958, regardless
of the maximum takeoff gross weight,
for which a limit of validity of the en-
gineering data that supports the struc-
tural maintenance program (hereafter
referred to as LOV) is required in ac-
cordance with § 25.571 or § 26.21 of this
chapter after January 14, 2011.
(b)
Limit of validity.
No certificate
holder may operate an airplane identi-
fied in paragraph (a) of this section
after the applicable date identified in
Table 1 of this section unless an Air-
worthiness Limitations section ap-
proved under Appendix H to part 25 or
§ 26.21 of this chapter is incorporated
into its maintenance program. The
ALS must—
(1) Include an LOV approved under
§ 25.571 or § 26.21 of this chapter, as ap-
plicable, except as provided in para-
graph (f) of this section; and
(2) Be clearly distinguishable within
its maintenance program.
(c)
Operation of airplanes excluded
from § 26.21.
No certificate holder may
operate an airplane identified in
§ 26.21(g) of this chapter after July 14,
2013, unless an Airworthiness Limita-
tions section approved under Appendix
H to part 25 or § 26.21 of this chapter is
incorporated into its maintenance pro-
gram. The ALS must—
(1) Include an LOV approved under
§ 25.571 or § 26.21 of this chapter, as ap-
plicable, except as provided in para-
graph (f) of this section; and
(2) Be clearly distinguishable within
its maintenance program.
(d)
Extended limit of validity.
No cer-
tificate holder may operate an airplane
beyond the LOV, or extended LOV,
specified in paragraph (b)(1), (c), (d), or
(f) of this section, as applicable, unless
the following conditions are met:
(1) An ALS must be incorporated into
its maintenance program that—
(i) Includes an extended LOV and any
widespread fatigue damage airworthi-
ness limitation items approved under
§ 26.23 of this chapter; and
(ii) Is approved under § 26.23 of this
chapter.
(2) The extended LOV and the air-
worthiness limitation items pertaining
to widespread fatigue damage must be
265
Federal Aviation Administration, DOT
§ 121.1115
clearly distinguishable within its
maintenance program.
(e)
Principal Maintenance Inspector ap-
proval.
Certificate holders must submit
the maintenance program revisions re-
quired by paragraphs (b), (c), and (d) of
this section to the Principal Mainte-
nance Inspector for review and ap-
proval.
(f)
Exception.
For any airplane for
which an LOV has not been approved as
of the applicable compliance date spec-
ified in paragraph (c) or Table 1 of this
section, instead of including an ap-
proved LOV in the ALS, an operator
must include the applicable default
LOV specified in Table 1 or Table 2 of
this section, as applicable, in the ALS.

(a)
Applicability.
Except as provided
in paragraph (o) of this section, this
section applies to transport category,
turbine-powered airplanes with a type
certificate issued after January 1, 1958,
that, as a result of original type cer-
tification or later increase in capacity
have:
(1) A maximum type-certificated pas-
senger capacity of 30 or more, or
(2) A maximum payload capacity of
7,500 pounds or more.
(b)
New Production Airplanes.
Except
in accordance with § 121.628, no certifi-
cate holder may operate an airplane
identified in Table 1 of this section (in-

the State of Manufacture issued the
original certificate of airworthiness or
