MEL - CDL Flashcards
What is TOI (technical operationnal impact) ?
MEL/CDL items that has no airworthiness impact but have operational consequences for dispatch
What are the 3 possible aircraft status in the left column of the MEL entries ?
NIL: no doubt possible on the origin of the failure
ACTUAL alert: failure of the system confirmed
FALSE alert: failure of the monitoring system confirmed
What are the 3 possible message on the the Conditions of Dispatch column of the MEL entries ?
NO DISPATCH
Items xx-xx-xx
Not related to MEL (solution is obvious)
Who is responsible for the identification and confirmation of the failure as well as the application of the good corresponding MEL items ?
The crew, otherwise it is NO GO
Until when MEL is applicable ?
Until aircraft moves by its own means.
Usage is still recommended until commencement of take off:
- GO: recommended to apply MEL recommendations
- NO GO or maintenance procedure: the captain must return to gate
(In flight it may be used to help the decision making, on the possibility to repair the failure at destination)
Can the crew accept a MEL technical deviation alone ?
Yes provided no maintenance action is required
If there is several MEL technical deviation, all of them are GO. Do you accept ?
Yes provided you take into account the possible interaction between each failure and also the context of the flight.
When you have an intermittent failure, which date is considered for the start of the MEL interval repair ?
If the failure appears again on the leg following the correction, you apply the date of the original failure.
If its on another leg, you apply the date of the new failure.
Definition of the MEL repair interval A,B,C and D ?
A: - days, x flights ?
B: 3 days
C: 10 days
D: 120 days
Flight/Day of the failure occurence is not counted
What is the repair interval of an item considered inop (because of another inop item) ?
Repair interval of the original inop item
What is the definition of extended overwater flight ?
Flight beyond 400Nm from land
Can you dispatch an aircraft if it has a MAINTENANCE message on SD ?
Yes except on some msn for AIR BLEED MAINTENANCE
Any part not included in CDL is necessary for aircraft dispatch. True or False ?
True
What is the max interval between visual inspection for a repair with high speed tape ?
3 days
If more than 3 items have negligible impact on performance computations, how performance is affected ?
TO and climb limiting weight reduced by 50kg by every additional CDL items
En route limiting weight reduced by 60kg by every additional CDL items
