test procedure and flight check-off
form, and in accordance with that
form, flight test each aircraft produced.
(b) Each production flight test procedure must include the following:
(1) An operational check of the trim,
controllability, or other flight characteristics to establish that the production aircraft has the same range and
degree of control as the prototype aircraft.
(2) An operational check of each part
or system operated by the crew while
in flight to establish that, during
flight, instrument readings are within
normal range.
(3) A determination that all instruments are properly marked, and that
all placards and required flight manuals are installed after flight test.
(4) A check of the operational characteristics of the aircraft on the ground.

characteristics at rated maximum continuous power or thrust and, if applicable, at rated takeoff power or thrust.
(2) At least five hours of operation at
rated maximum continuous power or
thrust. For engines having a rated
takeoff power or thrust higher than
rated maximum continuous power or
thrust, the five-hour run must include

30 minutes at rated takeoff power or
