Factory (all at Kamra)

The conception of idea to establish Pakistan Aeronautical Complex dates back to the early seventies. The rationale behind this idea was both economic and strategic. The aim before the policy makers was to create an indigenous production facility in which aircraft and engines could be overhauled and repaired without sending them abroad and doling out large sums of foreign exchange. Later years saw expansion in the role of PAC in terms of aircraft and engines production, upgrade programmes and joint ventures.

Since inauguration of the first of its four factories in 1978, Pakistan Aeronautical Complex has not looked back. In the two decades, it has vastly expanded the scope of work, commenced new and more challenging projects, created a veritable centre of excellence in military aviation and information technology, and above all, realised the original goal of self-reliance. Eversince its inception, Pakistan Aeronautical Complex has become the backbone of Pakistan Air Force in maintenance; supporting its major weapon systems by providing rebuild services for aircraft, engines and components; providing spare support, structural repairs and major rectification. Manufacture of Mushshak aircraft and collobaration with China in K-8 jet trainer programme are landmark achievements of PAC which have lent tremendous creditability to this industry. More recently PAC has also ventured into the area of system upgrades and manufacture of airborne avionics systems in partnership with some foreign collobarations. Having acquired necessary resources and expertise. PAC is fast expanding its role and making all-out efforts to turn itself into a self-supporting outfit. Already, it is ensuring that the country spends least amount of foreign exchange on maintenance of the PAF fleet of fighter and trainer aircraft. Except for import of certain essential spares, rest everything is produced or repaired locally.

In PAC, quality of products and services occupies the fundamental importance. Quality received tremendous boost recently when the four factories of this complex were certified to ISO-9000 quality management system by the leading international auditing firms. This has enormously enhanced the prestige and the credentials of this complex with the aviation circles around the world. They now consider us serious contenders for joint ventures and partnerships. With this, PAC is now committed to a standard which can neither be lowered nor compromised in future.
