General Matters

3.1 LAMS Schedule. The BGA LAMS schedule has been discontinued by the CAA (CAA/LAMS/A/1999/BGA issue 1) in future all Motor Gliders and Tugs should use the standard LAMS as published by the CAA (CAP 411). At the next Annual check the schedule should be amended by removing the stickers referring to the BGA or by deleting them. With the revised BGA approval granted by the CAA, the change of LAMS has no effect on the certification process or work content completed by the BGA inspector. New lams reference CAA/LAMS/A/1999 issue 1, amendment 1. Any additional items should be entered into CAP 543 Time Limited Task and Component Change Record.
