Of late a few of us have gone through changes on our aircraft that have affected our aircrafts Weight and Balance and required a change of permit. Most recently we have had an MTO Sport that was upgraded from a 912 to a 914 and we have a Calidus that has also had an upgrade from a 912 to a 914. To cut a long story short, the MTO Sport paperwork was submitted by an LAA engineer and the weight and balance was carried out by professionals. https://www.loadmasters.co.uk/physical-weighing-services/
The Calidus was upgraded by a very well respected engineer in our community who took another route and had problems getting the weight and balance sorted. This has held up the permit update and of course meant that the pilot or pilots have been unable to use their aircraft for quite a long period.
I am posting this as it should not have happened and with the loadmasters link above being a tried and tested way forward, hopefully this will prevent delays like this in the future.
