discrepancies exist. After the operational inspection a test flight is required to insure that the
engine and aircraft meet all of the manufacturer's performance and operational
specifications prior to releasing the aircraft for normal service.
WARNING
Although the engine fuel system was adjusted at engine test, the fuel system must be
checked and adjusted in accordance with Chapter 23 "Fuel System Adjustment," of
this manual and current TCM service documents when the engine is first installed
into the airframe and at 100 hour intervals to insure proper operation. All
discrepancies must be corrected prior to test flight.
6-9 FLIGHT TESTING
CAUTION . . . Adhere to engine operating limits published in this Manual and the Pilot's
Operating Handbook/Airplane Flight Manual during test flight.
Ambient air and engine operating temperatures are of major concern during this test flight.
Accomplish a normal pre-flight run-up in accordance with the airframe manufacturer's Pilot's
Operating Handbook/Airplane Flight Manual. Conduct a normal take-off with full power and
monitor the fuel flow, RPM, oil pressure, cylinder head temperatures and oil temperatures.
Reduce to climb power in accordance with the flight manual and maintain a shallow climb
attitude to gain optimum airspeed and cooling. Rich mixture should be used for all
operations except leaning for cruise economy. Leaning operations must be performed in
accordance with the airframe manufacturer's Pilot's Operating Handbook/Airplane Flight
Manual.
Level flight cruise should be at 75% power with best power or richer mixture for the first hour
of operation. During the second hour, alternate power settings between 65% and 75%
power with the appropriate best power mixture settings. The best power mixture setting is
100°F to 150°F rich of peak exhaust gas temperature.
The descent should be made at low cruise power settings with careful monitoring of engine
pressures and temperatures.
Any abnormal conditions detected during test flight must be corrected and any final
adjustments must be accomplished prior to releasing the aircraft for normal service.
