1. Confirmer l’item, la catégorie et le nombre requis dans le MEL officiel (lien PDF).
2. Appliquer les procédures (O) et/ou (M) du MEL avant dispatch — texte officiel ci-dessous.
3. Placard (texte MEL) :
Apply sticker on Pressurization Control Panel.
4. Journey log / other instructions (texte MEL) :
Print the following information in the journey log sheet.
FORWARD ENTRY DOOR STOP FITTING BROKEN OR MISSING - DO NOT EXCEED 6.0 PSI
CABIN DIFFERENTIAL
or
AFT DOOR WITHOUT AIRSTAIRS DOOR STOP FITTING BROKEN OR MISSING - DO NOT
EXCEED 3.4 PSI CABIN DIFFERENTIAL
5. Respecter toutes les restrictions du MEL — ne pas en inventer.
(O) OPERATIONS PROCEDURES — texte MEL :
52-05-01B Forward Entry Door
NOTE: Do not exceed the maximum pressure differential of 6.0 psi. Limit flight altitude to 27,000
feet or lower to maintain a cabin altitude of less than 8,000 feet.
1. Select a landing altitude of 8,000 ft. MSL on the cabin pressure control panel. Cabin altitude will
ascend to slightly less than 8,000 ft. during climb to cruise altitude.
NOTE: Actual landing airport altitude may be selected if flight altitude is limited to 13,000
feet.
2. Monitor differential pressure indicator during climb to ensure maximum pressure differential of
6.0 psi is not exceeded.
3. Select actual landing airport altitude after initiating descent. If required to hold during descent, it
may be necessary to increase the landing altitude in accordance with the Differential Pressure
Schedule below.
4. Lower cabin altitudes may be obtained by appropriate selection of flight altitude and
cabin/landing altitude in accordance with the Differential Pressure Schedule below.
