    - Com 1, Nav 1, Mic
    before turning avionics bus 2 because it cannot be tuned
    i)com 1 and nav 1 - tune to active frequency
    j) com 1 mic and nav 1 - select
    Avionics bus 2 is set to OFF
    ap, comm2, transponder, audio panel, nav 2, mfd
    k) avionics bus 2 - off
  3. land asap before turning flap = most electrical load

  3. authorised maintenance personnel must do electrical system inspection pror to next flight
107
Q

Low volts annunciator comes on or does not go off at higher RPM

A
  1. MASTER switch (ALT) - off
  2. alt field circuit breaker - check in
  3. master ALT and BAT - on
  4. low volts annuncaitors - check off
  5. m BUS volts - check 27.5 V (minimum)
    6.M batt amps - check charging +
    If low volts annunciator remains on
  6. master switch (alt only) - off
    8.electrical load - reduce immediaetly
    a) avionics (bus 1) - off
    b)pitot heat - off
    c) beacon - off
    d) land - off
    e) taxi - off
    f) nav
    g) strobe
    h) cabin pwr 12v switch - off
    main battery supplies electrical power to the main and essential buses
    i) com 1 and NAV 1 - tune active frequency
    j) com 1 mic and nav 1 - select
    Autopilot comm 2 transponder audio panel
    nav 2 MFD
    9, land as soon as practical

Q

Red X - PFD A/s indicator

A
  1. ADC/AHRS circuit breaker - check in
    if open, reset circuit breaker. If circuit breaker opens again, do not reset
  2. standby airspeed indicator - a/s
109
Q

Red X - PDF altitude indicator

A
  1. adc/ahrs circuit breaker - check in (ess bus and aven bus 1) if open reset circuit breaker. if circuit breaker open again, do not reset
  2. standby altimeter - check current barometric pressure set
110
Q

Red X - PFD attitude indcaitor

A
  1. adc/ahrs circuit breaker - check in. If open, reset circuit breaker. If circuit braker opens again, do not reset
  2. standby attitude indicator - use for attitude information
111
Q

Red X horizontal situation indcaitor HSI

A
  1. adc/ahrs circuit breaker - check in (essen bus and avn bus 1)
    if open reset circuit breaker opens again, do not reset
  2. non stabilized magnetic ompass - use for heading
112
Q

Ap or Ptrm annuncaitor come on

A
  1. control wheel - grasp firmly
  2. a/p trim disc button - press and hold
  3. elevator trim control - adjust manually
  4. auto pilot circuit breaker - open (pull out)
  5. a/p trim disc button - release
    do not engage ap until the cause of the malfunction has been corrected
113
Q

Low vaccum annunciator comes on

A
  1. vacuum indicator vac - check eis engine page (make sure vacuum pointer is in green band limits)
114
Q

Co lvl high annunciator come on

A
  1. cabin ht control knob - off
  2. cabin air control knob - on
  3. cabin vents - open
  4. cabin windows - open (163)
    co level annuncaitor remains on
    5 land as soon as practical
115
Q

Static source blocked

A

alternate static source air valve should be pulled on
ALT static air valve is on = maximum airspeed variation from normal static source is 11 knots
altimeter variation is 50 feet

116
Q

Spark plug fouling

A
  • lean the mixture, determined if a richer mixture is needed –> magneto both
117
Q

magneto malfunction

A
  • engine roughness / misfiring
  • changing magneto switch from both to the L and R position will identify which magneto is amflunctioning
  • select differnet power setting and enrichen the mixture to determine if operation on both magneto
118
Q

Engine driven fuel pump failure

A

sudden reduction in the fuel flow indication immediately before a loss of power while oeprating from a fuel tank with adequate fuel

  • selectr fuel pump on
119
Q

Excessive fuel vapour

A
  • taxi operation when operating at higher altitude and warm temperature
  • flucuation greater than 1 GPH
    leaner mixture or with larger fluctuation can result in power surges + correct cause power loss
    Fuel pump - on and adjust mixture
120
Q

Low oil pressure

A

oil pressure sending unit / relief valve malfunctioned

land

121
Q

Electrical power supply malfunction

A

main battery is less than 5 amps
if charging current remain above this valuve = overherat + evaporate
charge voltage increases to more than 31.75
–> master off
