Just to clarify a few things on the fan cowls.
They are not opened on a daily check at all. Only on a weekly for the IDG oil level check and also on service checks.
The fan cowls can be unlatched and look like the photo from the report with a large gap between the cowls and engine OR they can be unlatched and be perfectly flush and without bending down can appear to be closed and latched.
The fan cowl closure is subject to a Verification check by 2 separate engineers at all times.
