Sociedade de Manutenção e Revisão de Hélice, lda.


Aerohelice – Propeller Maintenance and Overhaul Society Lda – was established in February 1981. Delivering a professional, competent and qualified work, the recognition by the market has inevitably grown. As the clients list grew, we had to move twice in a short period, for a more spacious workshop. Solicitations are now from many diverse countries, proving the highly professional work developed at Aerohelice Lda. As before, our high quality requirements and dedication criteria are the same. The rigor starts with our employees and their training, as we will not give up our reliability and credibility.


Aerohelice positions itself at a high level because we are exigent and responsible. The continuous technical update and refining techniques, in cooperation with parts and components manufacturers, are patent in various different certificates, and EASA Part 145 and ISO 9001:2015 approvals.
