Subpart D—Airplane Requirements

§ 125.91 Airplane requirements: Gen-

an airplane governed by this part un-
less it—

(1) Carries an appropriate current

airworthiness certificate issued under
this chapter; and

(2) Is in an airworthy condition and

meets the applicable airworthiness re-
quirements of this chapter, including

those relating to identification and
equipment.

(b) No person may operate an air-

plane unless the current empty weight
and center of gravity are calculated
from the values established by actual
weighing of the airplane within the
preceding 36 calendar months.

not apply to airplanes issued an origi-
nal airworthiness certificate within the
preceding 36 calendar months.

§ 125.93 Airplane limitations.

No certificate holder may operate a

that, for a particular model of airplane
used in cargo service, literal compli-
ance with any requirement under para-

would not contribute materially to the
objective sought, the Administrator
may require compliance with only
those requirements that are necessary
to accomplish the basic objectives of
this part.

are easily accessible in flight. There
