System failure during MEL applicability
Dear all,
probably a redundant question but I still couldn't figure out a definitive answer based upon some facts. Let's imagine the following scenario : during pushback the airplane has a system failure. As per the regulator/company procedures the MEL is still applicable. The crew checks the MEL and finds out that the system is not required to be operative or enough redundancy exists in order to dispatch the flight. An operational procedure may be required but there is no maintenance procedure associated.
Questions :
1) Is the crew legally required to make an entry in the ATL at that stage and therefore have maintenance to raise a DDL (or possibly fix the problem) thus requiring a return to stand ?
2) Provided no maintenance procedure has to be performed, can the crew continue the flight provided that an entry will be made at destination and eventually a DDL raised or the system fixed ?
Thank you all for your inputs.
