Modifications

Part 3

None this issue. General Matters

3.1 Variation and recording of inspections and AD’s As a general reminder, it should be noted that a BGA inspector may NOT vary the content of an Airworthiness Directive in any way. AD’s should be embodied by inspection, replacement, modification or as described, exactly and completely as detailed on the AD. Should it be necessary to necessary to vary an AD, due to an error, for example, then the issuing authority must be consulted.

Compliance with AD’s and required inspections etc. must be recorded in the glider or aircraft log book. It is acceptable to record work details on worksheets but the AD must be referenced in the log book entry.
