Explication (français)
Dispatch selon le MEL Air Inuit AILO-0903 (texte extrait du PDF dans l’app). Catégorie(s) de réparation : C — 10 jours calendaires. 4 condition(s) de relief extraite(s) du tableau officiel (installé / requis / remarques). Une procédure (O) opérations s’applique — voir ci-dessous (texte MEL anglais). Une procédure (M) maintenance s’applique avant dispatch — voir ci-dessous. Les switch names, notes et chiffres ci-dessous sont ceux du MEL. Ne pas ajouter d’étape qui n’y figure pas.
Procédure équipage — (O) / (M) / placard

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 adjacent to affected pump switch.

4. Journey log / other instructions (texte MEL) :

Print the following information in the journey log sheet. (NO. 1) (NO. 2) TANK (AFT) (FWD) BOOST PUMP INOP - MAINTAIN MINIMUM FUEL IN ASSOCIATED TANK

5. Respecter toutes les restrictions du MEL — ne pas en inventer.

(O) OPERATIONS PROCEDURES — texte MEL :

28-01-03-01 Aft Pumps NOTE 1: Observe the Flight Manual limitations concerning lateral fuel imbalance. Plan fuel load to allow for the appropriate minimum fuel. Range and/or payload restrictions may result. NOTE 2: Perform an operational check of the fuel crossfeed valve and ensure the Fuel Crossfeed Valve C/B (P6-3) has not tripped. Enter valve failure conditions resulting from the operational check in the Maintenance Log. 1. The minimum fuel requirements with an inoperative aft fuel boost pump assures that the operative forward fuel boost pump and suction feed inlet remain submerged during rotation to high nose up attitudes during takeoff or go around. 2. In the event the second (forward) boost pump in a main tank fails, the engine will operate satisfactorily on suction feed. With both tank No. 1 boost pumps inoperative, APU operation may become unreliable at altitudes above 25,000 feet. 3. For flight planning purposes, the fuel in the associated tank must be considered unusable. This fuel will be accounted for in the UNUSABLE FUEL on the flight release. NOTE: At high altitude, thrust deterioration or engine flameout may occur. 28-01-03-02 Forward Pumps NOTE 1: Observe the Flight Manual limitations concerning lateral fuel imbalance.

(M) MAINTENANCE PROCEDURES — texte MEL (maintenance ; l’équipage vérifie que c’est fait) :

28-01-03-01 Aft Pumps 1. Position the associated AFT FUEL PUMP switch to OFF. 2. Open and collar the associated aft fuel pump circuit breaker on Power Distribution Panel P91 or P92. 3. Notify dispatch, the fuel required will increase. 28-01-03-02 Forward Pumps 1. Position the associated FWD FUEL PUMP switch to OFF. 2. Open and collar the associated forward fuel pump circuit breaker on Power Distribution Panel P91 or P92. 3. Notify dispatch, the fuel required will increase.
