Numpty pilot
As a 145 QM I would want to know what was going on when the tapes of the flights where downloaded. ( I assume they are on the 737) As the QM I would be asking some awkward questions to operations as to what was happening on these flights. Have you spoke to your maintenance QM? we are approcable and can help and support on issues like this as it is our techies signing for the plane and saying it is servicable, but if we dont get facts from crew it is your lives on the line.
failing that the old fashioned corrective education session around the back of the hangar can be very soothing.
