§ 121.627 Continuing flight in unsafe
conditions.
(a) No pilot in command may allow a
flight to continue toward any airport
to which it has been dispatched or re-
leased if, in the opinion of the pilot in
command or dispatcher (domestic and
flag operations only), the flight cannot
be completed safely; unless, in the
opinion of the pilot in command, there
is no safer procedure. In that event,
continuation toward that airport is an
emergency situation as set forth in
§ 121.557.
(b) If any instrument or item of
equipment required under this chapter
for the particular operation becomes
inoperative en route, the pilot in com-
mand shall comply with the approved

specified in the certificate holder’s

ment List must:

able to the pilot.
(5) The airplane is operated under all
applicable conditions and limitations
contained in the Minimum Equipment
List and the operations specifications
authorizing use of the Minimum Equip-
ment List.
(b) The following instruments and
equipment may not be included in the
Minimum Equipment List:
(1) Instruments and equipment that
are either specifically or otherwise re-
quired by the airworthiness require-
ments under which the airplane is type
certificated and which are essential for
safe operations under all operating
conditions.
(2) Instruments and equipment re-
quired by an airworthiness directive to
be in operable condition unless the air-
worthiness directive provides other-
wise.
(3) Instruments and equipment re-
quired for specific operations by this
part.
(c) Notwithstanding paragraphs (b)(1)
and (b)(3) of this section, an airplane
with inoperable instruments or equip-
ment may be operated under a special
flight permit under §§ 21.197 and 21.199
of this chapter.
