Question is say if you get a PACK light (etc) on after engine start but still connected to the tug? What do you do? What happens if they had disconnected the tug? NNC obviously but also back to stand ? Or continue ? Then MEL it on next sector with mx.
Thanks
Hi,
As You correctly write, In EASA land the MEL is applicable till the ‘Commencement of flight’ i.e. the point when an aeroplane begins to move under its own power for the purpose of preparing for take-off. With that being said "Operators should include guidance in the MEL to deal with any failures which occur between the commencement of the flight and the start of the take-off".
So in Your scenario you are still under the MEL dispatch applicability. A lot will depend on the type of failure and whether or not as flight crew You are authorized to raise MELs and dispatch yourself. What usually happens with many Operators nowadays is that flight crew hold authorization to enter and dispatch MELs items that do not require any maintenance action or might only require a minor maintenance action such as a reset of circuit breakers. If that is your case and the failure you have allows it, you can raise the defect and dispatch yourself according to the MEL.
Once You have started moving under your own power and end up with a failure, it is up to your operator to include guidance on what they want you to do. For example my operator requires that if an MEL has a maintenance procedure to be performed it's a NO GO, same story if it's a NO DISPATCH item. So back to the stand. But again different guidelines exist so check your MEL PREAMBLE and your OM-A chapter 8.6 or the chapter that deals with MEL applicability to know what to do.
