Inertia dampeners of large ship A fail to achieve "neutral buoyancy" in planetary gravity, when another ship B was landing-gear-locked onto it, while A had locked landing gears
(1) lock the landing gears of a large atmospheric ship A
(2) lock a small atmospheric ship B onto A using B's landing gears
(3) depower B (probably not necessary to reproduce)
(4) take off with A
Result: The inertia dampeners of A will fail to achieve "neutral buoyancy".
This will NOT occur when at the moment B locked onto A, the landing gears of A were NOT locked.
