GABORONE — The Nigerian Air Force (NAF) has taken delivery of the first four out of 10 MFI-17 Super Mushshak primary trainer aircraft ordered from the Pakistan Aeronautical Complex (PAC), five months after the two parties signed a supply and delivery agreement.

The light trainer aircraft were handed over to NAF Chief of Air Staff Air Marshal Sadique Abubakar by PAC chairman Arshad Malik and Pakistani Air Force (PAF) Chief of Air Staff Air Marshall Sohail Aman on Monday in a ceremony that was held at the Kaduna Air Force base on Monday.

They were commissioned into service four days after delivery to Kaduna on Dec. 1. According to the supply contract signed in June this year, the PAC would also provide technical training to the NAF teams charged with operating and maintaining the aircraft.

"We are very happy with this deal and we are hopeful that it will help us to open up new markets elsewhere. This contract includes the provision (to Nigeria) of operational training and technical support by the Pakistani Air Force," Malik said.

Flight training and aircraft maintenance crews from the PAF are expected to set up relevant facilities in Abuja shortly. The four are part of a batch of eight that will be loaned to Nigeria until the delivery of its aircraft order.

Pakistan keeps aging Mirages flying

KAMRA, Pakistan: The sprawling complex at Kamra, west of Islamabad, reverberates at the thundering take-off of a Mirage Rose-1, the latest aging fighter jet to have been gutted and reassembled by the Pakistani Air Force.

Fifty years after Pakistan bought its first Mirages, many planes in the venerable fleet are still being patched up, overhauled and upgraded for use in combat, years after conventional wisdom dictates they should be grounded.

That includes one of the first two planes originally purchased from France’s Dassault in 1967, which was in a hangar at Kamra after its record fifth overhaul when AFP visited recently.

The techniques they have developed are reminiscent of — but far more high-tech and lethal than — the improvised methods used to keep classic American cars running on the streets of Havana.

“We have achieved such a capability that our experts can integrate any latest system with the aging Mirages,” says Air Commodore Salman M. Farooqi, deputy managing director of the Mirage Rebuild Factory (MRF) at the Kamra complex.

Pakistan bought its first Mirages to diversify its fleet, which in the late 1960s largely consisted of US-built planes: F-104 Starfighters, T-37 Tweety Birds and F-86 Sabres.

The Mirage became a popular choice, with the Air Force buying 17 different variants in later years, eventually owning the second-highest number of the fighter jets after France.

They performed bombing missions during Pakistan’s war with India in 1971 — one of the shortest conflicts in history, lasting just 13 days and leading to the creation of Bangladesh.

But Mirages flew on, also carrying out reconnaissance missions in India, and intercepting and shooting down Soviet and Afghan planes that violated Pakistani airspace during the Soviet war.

Usually, the jet has two or three life cycles, each spanning around 12 years. But overhauling them abroad was expensive for Pakistan, a developing country whose budget is already disproportionately tilted toward its military and which has historically received billions in military assistance from countries such as the US.

So, with the help of experts from Dassault, the air force decided if you want something done for the right price, you’ve got to do it yourself.


The Mirage Rebuild Factory was established at the Pakistan Aeronautical Complex (PAC) in 1978, and in the years since has saved “billions” of dollars for Pakistan, according to Group Captain Muhammad Farooq, in charge of one of the maintenance hangars — though he said the exact figure was difficult to pin down.

The planes take some seven weeks to be overhauled and repainted, he said, adding that usually the MRF has the capacity for more than a dozen planes a year. Its calendar for the next decade or so is already booked up.
At least eight different Mirage variants, including the Mirage 5-EF, Mirage III-DP and Mirage-III Rose-I, were in one of the maintenance hangers when AFP visited.

Engineers and technicians were dismantling cockpit instrument panels and landing gear while undertaking a “non-destructive inspection,” essentially an X-ray to detect faults in the wings and airframe.

Dozens of engines awaiting overhaul were piled in one hangar. Even planes that had suffered accidents such as fires breaking out have been patched back together at the facility.

Pakistan has also been buying up discarded Mirages from other countries to bring through the facility, said retired Air Marshal Shahid Lateef.

The most important technological improvement, developed with the help of South Africa, is the ability to integrate air-to-air refueling, Farooqi said.

The “identification of friend and foe” (IFF) system, which detects when a Mirage has been locked on to by the system of another plane, was also a key development, he said.

But even with the improvements and cost-saving measures, the aging planes are becoming more difficult to maintain.

“They have outlived their lives... after their overhauls (they) have become highly unreliable, we even met with lots of accidents,” Lateef said.

The best option to replace them would be the Rafale, as neighbor and arch-rival India — which has also flown and maintained Mirages for decades — is doing, signing a deal with Dassault in 2016.

The price tag is too much for Pakistan, however, retired Air Commodore Tariq Yazdani said.

Instead Pakistan plans to replace them with the JF-17 Thunder aircraft that it co-developed and co-produced with China, the original manufacturer.

Even as it becomes more urgent to phase them out, Mirages’ status as the grand dames of Pakistani military aviation cannot be dismissed, Yazdani, who has logged 1,500 hours flying them, told AFP.

It is a “very agile aircraft capable of penetrating deep into the enemy’s territory without being detected by radar, which makes its sole mission -– to drop bombs on the enemy’s position -– quite easy,” he said.

“It is an old aircraft,” said aviation writer Alan Warnes, author of two books on the Pakistani air force. “But Pakistani pilots have been flying this plane with the utmost accuracy and expertise.”

Conformal Coating

Conformal coating is an extra cost operation. Boards not in standard panel size will require additional tooling. Humiseal Coatings and Silicon types of conformal coating can be offered. Conformal coting is done as per coating map provided by the customer to meet the product requirement. Coating map is to include thickness of coating and no cat areas and components.

Optical and X-Ray Inspection

APF can perform the optical and 3D X-ray inspection of the product assembly upon the customer request and its reports can be sent with the product for Quality assurance to our valuable customer. These inspections reports are very useful if the product assembly contains BGAs and some fine pitch QFPs. X-ray inspection can be performed for electronic PCBs up to size of 400x400mm (16 inch x 16 inch). It is useful in determining BGA and micro BGA faults like short circuited balls, over and under sized balls, solder voids and quality of balls. It can also identify broken connections inside the ICs.

PCB Treatment

Availability of corrosive and conductive particles of the flux or solder past may lead to jeopardizing the product reliability in spite of excellent workmanship. This may not be applicable to the non-clean flux / solder paste but if the customer specify or supply consumable material with the RMA fluxes or VOC water based fluxes then PCB washing becomes an essential process in the product assembly. APF can offer PCB washing upon the customer request or from the selection of material by the customer specific applications. This can eliminate all the corrosive and conductive particle of flux from the product assembly. Lonic contamination can also be verified and reports can also be provided to the customer on request.
