VS A320 LGW Incident in 2000?
Airtours.
Among the AAIB's recommendations in the investigation report:
"It is recommended that the DGAC mandate aircraft modification aimed at appreciably reducing the likelihood of A320 fan cowl doors inadvertently remaining unlatched after maintenance. It is considered that, while measures to exhort maintenance personnel to ensure the doors are latched and to improve the conspicuity of unfastened latches may assist, they are unlikely to be fully effective and modification aimed at providing obvious indication of unlatched doors is required."
"It is recommended that the DGAC and Airbus Industrie consider the incorporation of a system to provide flight deck warning of unlatched fan cowl doors on the A319, A320, A321 and A330 aircraft types."
Enough said.
