Pakistan has been certified to build and conduct repair works of Swedish firm SAAB’s Airborne Warning and Control System (AWACS).

“For the first time in history, Swedish SAAB AWACS were built from scratch by another country, even to the disbelief of SAAB itself... who had declared the project technically impossible,” .

SAAB’s Erieye radar system is an Airborne Early Warning and Control (AEW&C) system that uses active electronically scanned array (AESA) technology.

The Erieye Ground Interface Segment is a major component of the software used by the Erieye system.

JF-17 THUNDER AIRCRAFT

JF-17 Thunder is an advanced, light-weight, all weather, day / night multi-role fighter aircraft; developed as a joint venture between Pakistan Aeronautical Complex (PAC), Kamra and Chengdu Aircraft Industry Corporation (CAC) of China. It possesses excellent air-to-air and air-to-surface combat capabilities. The state-of-the art avionics, optimally integrated sub-systems, computerized flight controls and capability to employ latest weapons provides decisive advantage to JF-17 over adversaries of same class.

This, all weather, multi-role light combat fighter has remarkable high combat maneuverability at medium and low altitudes. With effective firepower, agility and combat survivability, the aircraft is likely to emerge as a potent platform for any air force.

Progress

The first JF-17 prototype aircraft (called FC-1) was rolled out in May 2003. It made its first flight in August 2003. Later on, two more prototype aircraft were added for basic structure, flight qualities, performance and engine flight testing while two prototype aircraft were involved in comprehensive avionics flight testing.

The basic flight testing was completed in 2007 which also marked the arrival of JF-17 Thunder aircraft in Pakistan where it was formally presented to the nation as a Pakistan Day gift on 23 March 2007.

Over the years, 03 Blocks of JF-17 including Dual seat aircraft have been produced at PAC with continuous improvement and up gradation in the Avionics suite, flight controls and weapons carrying capability. The JF-17 aircraft was formally inducted in Pakistan Air Force by replacing aging fleet and currently 07 Squadrons of PAF are operating JF-17 aircraft.

Production

Pakistan Aeronautical Complex (PAC) holds 58% work share of JF-17 airframe co-production. A comprehensive infrastructure comprising state of the art machines and required skilled human resource has very quickly been developed at the Complex. The final assembly and flight testing of the aircraft was the first JF-17 co-production activity to start at PAC.

The first PAC produced aircraft was handed over to Pakistan Air Force in November 2009. Since then, aircraft are being produced regularly to meet the required schedule. The co-production of sub-assemblies and structural parts subsequently commenced and has sequentially attained the sustained production status.

Besides upgrading the production system, PAC has also upgraded its quality, technology and archive management systems to meet the production and management standards of a 4th generation fighter aircraft.

AIRCRAFT MRO​

JF-17 AIRCRAFT MRO​

Established since 2017, JF-17 aircraft MRO at Aircraft Rebuild Factory is the sole organization in the world for overhauling JF-17 aircraft. New JF-17 MRO hangar has been established which is having 16 aircraft docks capacity including two environmental controlled docks and 02 overhead cranes of 05 tons capacity each.

Each dock is equipped with dedicated electric and pneumatic power supply, fire suppression system and ground support equipment. It is capable to annually produce 16 aircraft. The overhauling of JF-17 aircraft also includes establishment / upgradation of aircraft painting / de-painting, components overhauling, AME overhauling and spares manufacturing facilities to meet the standards of advanced state of the art overhauling facilities.

Overhauling of JF-17 aircraft​

Overhauling process of JF-17 aircraft consists of a series of stages including de-painting, disassembly, on-board inspection, assembly and functional check flights.

After disassembly, aircraft electro-mechanical and avionics components are overhauled at shops in Components Rebuild Group (CRG), while pipes related to different aircraft systems such as hydraulic system, pneumatic system, environmental control system are overhauled by Production Support Group (PSG). Weapon Rebuild Group (WRG) overhauls the aircraft major weapon system components such as ejection seat, pylons, and launchers.

During onboard inspection of aircraft, inspection and repair of complete aircraft structure with the help of various non-destructive testing (NDT) methods is carried out to ensure structural integrity and health. Inspection of all pipes and electric looms that are not disassembled is also carried out in this phase. After completion of onboard inspection, corrosion treatment and internal painting of aircraft structure is carried out.

During assembly phase, complete aircraft system buildup including installation of components, pipes, cables, rods is carried out at different phases. Operational checks of aircraft systems such as hydraulic system, pneumatic system, electric system is also carried out as per phase wise plan.

After complete operational checks of all aircraft systems, fly-by-wire flight control system of aircraft is checked using a Movable Ground Test Facility (MGTF). The aircraft is then released for functional check flights to conduct aerial tests of aircraft for complete systems verification. After checks flights, aircraft is painted and handed over to user.

In addition to overhauling of aircraft, JF-17 MRO is well equipped with trained manpower and necessary resources in order to undertake any major structural modification and upgradation of aircraft systems which are issued by OEM. Some major structural modifications and system upgradation include reinforcement of fuselage frame 9040, reinforcement of ventral fin, SBP to SP upgradation, Wing Rib-7 reinforcement using composite, DEFIS upgradation and ECS system modification.
