Guides and insights for aircraft maintenance engineers.
A practical reference table mapping ATA chapters to B1 (mechanical), B2 (avionics) and shared privileges — plus the chapters that genuinely split, like 21, 27 and 73.
How to correctly log B1+B2 dual-licence tasks so they count toward both recency clocks under EASA 66.A.20(b)(2) — without double entry or manual arithmetic.
Understand EASA Part-66 recency (66.A.20(b)(2)): the 100-day/180-task rule, the 6-month spread requirement, and how to track it per aircraft type without a spreadsheet.
