The slow rate of production for the Hamilcar appears to be the result of a combination of factors. There was a great demand on the specific types of wood required to build the glider, and difficulty in finding suitably large airfields with enough skilled personnel where the gliders could be constructed and stored; it also appears that a lack of official priority and poor management at GAL also impeded production. Between March and August 1942 GAL had promised eighteen Hamilcars would be built and delivered, but by September only one had actually appeared; this slow rate of production so concerned the Ministry of Aircraft Production that it appointed an 'Industrial Panel' of three senior industrial experts to visit GAL and detail the causes of the problems. The panel visited GAL in early September 1942 and issued a report on 24 September which stated that the root of the problems was that GAL appeared to have taken a bigger workload than it could handle, which was exacerbated by poor organisation and management skills. There were also conflicts between GAL and the Hamilcar Production Group which hurt production; the Group had been formed by the Ministry on 28 July in an attempt to speed up production, but senior GAL managers resented this and failed to co-operate fully with the Group. The panel also identified a 'piecemeal method of ordering' by the Ministry of Aircraft Production as a cause of further delays. Ultimately several senior managers and staff at GAL were replaced on the recommendation of the panel in an attempt to decrease internal conflicts and speed up production.
