2. MASK Pushbutton……….PRESS ALL
   (Each C/M presses the MASK pushbutton on his communications panel and, if the breathing noise is disturbing, presses the INPH HOT pushbutton and uses the PTT with the headphones or with the cockpit speakers.)

NOTE: Descend to 10,000 ft or MEA, whichever higher.

CAUTION: If structural integrity is suspected, reduce airspeed as much as possible (min. VREF / max. VFE). Extend flaps 23deg and landing gear.

CAUTION: The technical crew must use oxygen while the cabin altitude is above 10000 ft. The Loadmaster will supply oxygen to those passengers requiring it.

Question 11

LOSS OF PRESSURIZATION (LOSS OF CABIN PRESSURIZATION)

Answer 11

NOTE: The DOOR UNLK warning with origin at the crew door or ramp/cargo door will result in a cabin depressurization. If at the end of this procedure, the DOOR UNLK warning is still on, consider to follow up the “DOOR UNLOCKED” Emergency Procedure.

1. Masks……….ADJUSTED. ALL
   (Each C/M adjusts his mask and C/M-2 checks that the Oxygen Switch is set to ON and both C/M set the Mixer Selector at NORMAL position.)
2. MASK Pushbutton……….PRESS. ALL
   (Each C/M presses the MASK pushbutton on his communications panel, and if the breathing noise is disturbing, presses the INPH HOT pushbutton and use the PTT with the headphones or with the cockpit speakers.)

NOTE:
Descent will be performed until the CABIN annunciator goes off or until MEA, whichever higher.

If the actual aircraft altitude is high as well as the Cabin Variometer pressurization loss, the descent will be performed at MAX VMO.

CAUTION: If structural integrity is suspected, reduce airspeed as much as possible (min. VREF / max. VFE). Extend flaps 23deg and landing gear.

CAUTION: Technical crew must use oxygen while the cabin is above 10,000 ft. The Loadmaster will supply oxygen to those passengers requiring it.

NOTE: If the cabin altitude control cannot be restablished in Manual Mode and there are no passengers, the flight can go on at cabin altitude of 10,000 ft or higher.

NOTE: If the flight is necessary to continue for a considerable time with the aircraft depressurized, see the “OXYGEN DURATION TABLE”.

Question 12

DUAL DC GENERATORS FAILURE

Answer 12

1. BAT BUS TIE Selector……….OFF. 2
2. Generators……….RESET / ON (MAX 2 ATTEMPTS). 2

A. If no generator is recovered:

CAUTION: When the TRU selector is not in OFF position, LH and RH miscellaneous buses are lost.

3. TRU Selector……….1. 2
   (If the TRU-1 magnetic indicator is not in line, change to position 2 and check that its magnetic indicator stays in line.)

CAUTION: If it is not possible to tie the bus bars correctly, the battery will power the associated bars while not empty or disconnected.
