Narrative:

Maintenance alerts 19-XXXX and 19-XXXY have been issued. The process of lowering the main gear doors on the airbus fleet to prevent overheating faults and alerts; bleed leak faults and alerts has been occurring for years. However; it is rare to see the required gear door safety collars installed. My concern is that this alert reinforces bad behavior. Some amt's (aviation maintenance technician) will insist on complying with the amm (airplane maintenance manual) and install collars. Other amt's will continue or begin to 'just drop the doors until block out time'. The amt's that comply will be ostracized by those who do not comply. There is already a lot of non- compliance; confusion and stress related to this specific issue.recommend that the issuers of maintenance alerts 19-XXXX and 19-XXXY familiarize themselves with A300 amm 32-xx-xx-xx-X. These safety collars are not readily available in the line maintenance centers. The requirement to install these safety collars every time the main gear doors are lowered is not standard/ observed. The requirement to document the installation of the collars (aml/eaml) is not standard/ observed on the line. It is clear that the intent of the alert is to reduce delays associated with overheating during the summer. Also; the installation; removal and documentation of anything during preflight/ block out time is ripe with opportunity for errors. Additionally; we have personnel involved with pushbacks that pose another major; major safety concern.
