========================================================================

BEFORE STARTING ENGINE
----------------------
[ ] Seat belts ................................................. Fastened
[ ] Fuel shut-off valve .............................................. On
[ ] Cyclic/collective friction ...................................... Off
[ ] Cyclic, collective, pedals ......................... Full travel free
[ ] Throttle ........................................... Full travel free
[ ] Collective ................................... Full down, friction on
[ ] Cyclic neutral .......................................... Friction on
[ ] Pedals ...................................................... Neutral
[ ] Governor ........................................................ Off
[ ] Circuit breakers ................................................. In
[ ] Carb heat ....................................................... Off
[ ] Mixture ................................................... Full rich
[ ] Mixture guard ............................................. Installed
[ ] All switches/avionics ........................................... Off
[ ] Clutch ................................................... Disengaged
[ ] Altimeter ....................................................... Set
[ ] Rotor brake .............................................. Disengaged
[ ] Map light ....................................................... Off

STARTING ENGINE & RUNUP (HEADSET-OFF ONE EAR)
---------------------------------------------
[ ] Master switch .................................................... On
[ ] Throttle twists for priming ............................. As required
[ ] Throttle ..................................................... Closed
[ ] Area .......................................................... Clear
[ ] Strobe light ..................................................... On
** CAUTION: CAUTION – Be sure rotor blades are approximately level to avoid possible tailcone strike.
[ ] Ignition switch .................................... Start, then both
[ ] Started-On light ................................................ Out
[ ] Set idle speed .................................................. 55%
[ ] Clutch switch .................................... Engaged (no delay)
[ ] Alternator switch ..................................... On (no delay)
[ ] Blades turning .................................. Less than 5 seconds
[ ] Oil pressure in 30 sec. .............................. 25 psi minimum
[ ] Avionics, headsets ............................................... On
[ ] Wait for clutch light ........................................... Out
[ ] Warm-up RPM ................................................ 70 – 75%
[ ] Engine gages .................................................. Green
[ ] Warning lights .................................................. Out
[ ] Mag drop @ 75% RPM ................................. 7% max in 2 sec.
[ ] Carb heat check ....................................... CAT rise/drop
[ ] Sprag clutch check from 75% RPM ....................... Needles split
[ ] Doors .............................................. Closed & latched
[ ] Limit MAP chart ............................................... Check
[ ] Cyclic/collective friction ...................................... Off
[ ] Governor on ............................................ RPM 102-104%
[ ] Lift collective slightly, reduce RPM .... Horn/light at 97% rotor RPM
** CAUTION: CAUTION – Avoid continuous operation at rotor speed of 60-70% to minimize tail resonance.
** CAUTION: CAUTION – On slippery surfaces, be prepared to counter nose right rotation with left pedal as governor increases RPM.
** NOTE: NOTE – During run-up & shutdown, pilot should uncover right ear, open right door, and listen for unusual bearing noise. Failing bearing swill produce an audible whine or growl well before final failure.

SHUTDOWN PROCEDURE
------------------
[ ] Collective down ......................................... Friction on
[ ] Cyclic/pedals neutral ................................... Friction on
[ ] Governor ........................................................ Off
[ ] Idle at 70-80% ................................ CHT drop (~4 minutes)
[ ] Throttle ..................................................... Closed
[ ] Clutch switch ............................................ Disengaged
[ ] Wait 30 sec ....................................... Pull idle cut-off
[ ] Mixture guard ....................................... Back on mixture
[ ] Wait 30 sec ....................................... Apply rotor brake
[ ] Clutch light off .................... All switches off (battery last)
** CAUTION: CAUTION – Do not slow rotor by raising collective during shutdown. Blades may flap and strike tailcone.
** NOTE: Notes:
