One HD.35 was delivered to ther Swedish Army Aviation Service in August 1929 for evaluation as a primary trainer, designated Sk.5. It did not satisfy the requirements and further purchases did not follow. The sole copy of the Sk.5 went in 1926 to the flying military school F5 in Lyungbikhede, where it became the personal aircraft of pilot Arvid Flory. In the summer of 1929, it was sold into private hands. It continued to fly until 1940 with the new registration code SE-SAM.
