## 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:
