This is an earlier model 737-500 not a "Max".
I will stick my neck out here, until I can get more info. The Aircraft of today are DEIGNED to be flown every day, the philosophy is to fill them with paying passengers and keep them flying. When A/C are not in service ie flying, they still require maintenance, which = $$$$.
Now what has happend over the passed 11 months, to many questions here.
1 when was it last flown?
2, what is the service history on this A/C?
3, was the service completed correctly and fully signed off?
and many more questions to be asked.
I will have to research this one with some of the known aviation reporters out there and report back, I hope they find this one?
