Section 121.361

Applicability.

(a) Except as provided by paragraph
(b) of this section, this subpart prescribes requirements for maintenance,
preventive maintenance, and alterations for all certificate holders.
(b) The Administrator may amend a
certificate holder-s operations specifications to permit deviation from
those provisions of this subpart that
would prevent the return to service and

use of airframe components, powerplants, appliances, and spare parts
thereof because those items have been
maintained, altered, or inspected by
persons employed outside the United
States who do not hold U.S. airman
certificates. Each certificate holder
who uses parts under this deviation
must provide for surveillance of facilities and practices to assure that all
work performed on these parts is accomplished in accordance with the certificate holder-s manual.

section.
