Section 135.145 Aircraft proving and validation tests.
(a) No certificate holder may operate
an aircraft, other than a turbojet aircraft, for which two pilots are required
by this chapter for operations under
VFR, if it has not previously proved
such an aircraft in operations under
this part in at least 25 hours of proving
tests acceptable to the Administrator
including - 
(1) Five hours of night time, if night
flights are to be authorized;
(2) Five instrument approach procedures under simulated or actual conditions, if IFR flights are to be authorized; and

(3) Entry into a representative number of en route airports as determined
by the Administrator.
(b) No certificate holder may operate
a turbojet airplane if it has not previously proved a turbojet airplane in
operations under this part in at least 25
hours of proving tests acceptable to the
Administrator including - 
(1) Five hours of night time, if night
flights are to be authorized;
(2) Five instrument approach procedures under simulated or actual conditions, if IFR flights are to be authorized; and
(3) Entry into a representative number of en route airports as determined
by the Administrator.
(c) No certificate holder may carry
passengers in an aircraft during proving tests, except those needed to make
the tests and those designated by the
Administrator to observe the tests.
However, pilot flight training may be
conducted during the proving tests.
(d) Validation testing is required to
determine that a certificate holder is
capable of conducting operations safely
and in compliance with applicable regulatory standards. Validation tests are
required for the following authorizations:
(1) The addition of an aircraft for
which two pilots are required for operations under VFR or a turbojet airplane, if that aircraft or an aircraft of

not been previously proved or validated
in operations under this part.
(2) Operations outside U.S. airspace.
(3) Class II navigation authorizations.
(4) Special performance or operational authorizations.
(e) Validation tests must be accomplished by test methods acceptable to
the Administrator. Actual flights may
not be required when an applicant can
demonstrate competence and compliance with appropriate regulations
without conducting a flight.
(f) Proving tests and validation tests
may be conducted simultaneously
when appropriate.
