Q

Abort Start

A
  1. Twist Grip - off
  2. IGN switch - off
  3. Starter pushbutton - continue to operate until ITT decreases to normal range
  4. Fuel panel switches - off/closed
    Caut: failure to use ext pwr on subsequent starts may result in hot start
    Excessive rise in ITT, ITT rapidly through 870, and or low batt voltage indicate increased potential for hot start
    if light off does not occur within 10 seconds of twist grip idle - abort start

Q

XMSN Malfunction

A

if failure is imminent
1. land immediately
if failure is not imminent
2. reduce power
3. monitor transmission parameters
4. land as soon as possible

warn: Possible indications of imminent transmission failure may include: yaw attitude excursions with no control input, an increase in power required for a fixed collective setting, increased noise,
increased vibrations, or abnormal fumes.
note: transit min power required airspeed at low alt to effect a quick flare and immediate landing in event of imminent failure

Q

XMSN Chip

A

If xmsn chip message illuminated
1. Check for secondary indications
if secondary indications exist
2. Transmission malf EP - perform
3. Chip burner sw- activate and release
4. Transmission malfunction EP - perform
use of chip burner sw when relative oil px is below limits is prohibited
note: no chip burner on ground, chip burner only 3x per flight

17
Q

Loss of T/R thrust in a hover

A
  1. Twist grip - idle
  2. Cyclic - eliminate drift
  3. collective - increase to cushion the landing
    caut: slight rotation to the right can be expected on touchdown
18
Q

Loss of T/R thrust in cruise flight

A
  1. Collective - lower to eliminate yaw
  2. Airspeed - adjust to reach a suitable landing site
    on reaching point of intended landing
  3. autorotate
  4. twist grip - off prior to touchdown
    note: increase in power necessitates increase in speed to prevent helicopter from excessive yaw
19
Q

Tail Rotor Chip

A
  1. Reduce Power
  2. Chip burner sw - activate then release
    if message does not extinguish or on the 4th TR box chip message
  3. Land as soon as possible
    Warn: be prepared for complete loss of T/R thrust, high power settings may result in T/R gearbox fail
    note: same chip burner notes
20
Q

Hyd Sys #1 or #2 px loss

A
  1. Establish VMC
  2. Avoid rapid movement of flight controls
  3. Airspeed - reduce smoothly below 90 kias
  4. Affected SERVO sw - off
  5. Land as soon as possible
    Caut - pull up maneuvers and bank angles beyond 25 deg may result in excessive flight control loads
    note: pedals not boosted with #1 fail, rapid power change with #1 fail may result in uncontrollable yaw, unboosted pedals may not be able to control right yaw with strong right xwind
21
Q

A
  1. BAT sw - off
  2. Land as soon as possible
22
Q
