Pilatus PC-7

Development

Origins

Work on what would become the PC-7 commenced during the 1960s. It was based on the earlier piston-powered Pilatus P-3, the initial prototype being produced from the existing prototype P-3, principally differing by the substitution of its Lycoming O-435 engine with a Pratt & Whitney PT6A-20 turboprop power-plant. The termination of work was reportedly driven by a lack of market interest.

During 1973, it was decided to restart work on the programme; factors for its revival had included the 1973 oil crisis, the launch of the rival Beechcraft T-34C Turbo-Mentor, and the increasing age of existing trainer aircraft. To support the relaunch, another P-3 was obtained from the Swiss Air Force. After modifications, this aircraft first flew on . Further extensive modifications followed later in the programme, including the adoption of a new one-piece wing complete with integral fuel tanks, along with an altered tail fin and a bubble canopy. The flight test programme came to a close during Autumn 1977.

On , the first production aircraft made its first flight. Over time, sales of the PC-7 generated considerable profits, allowing the company to finance the development of further types of aircraft.

Further development

The PC-7 Mk.II M is a development of the PC-9's airframe and avionics, which was powered by the PC-7's smaller turbine engine, which reportedly achieved lower operating and maintenance costs. This variant was developed at the behest of the South African Air Force (SAAF), who later adopted the type. A batch of 60 PC-7 Mk.II Ms were locally assembled in South Africa using kits supplied by Pilatus for the SAAF; due to political considerations, these aircraft were not fitted with the armament hardpoints. Deliveries to the SAAF took place between late 1994 and 1996.

In addition to Pilatus' own improvement programmes, several third-party companies have independently developed their own upgrades for customer's PC-7. During the late 1990s, Israeli engineering firm Radom began offering a kit of new avionics for the type, which included a new mission computer, a wide-angle head-up display, along with various replacement communications and weapons-delivery systems.

During July 1998, Pilatus announced that it has come to an agreement with American company Western Aircraft, for the latter to act as a distributor for the PC-7 across the North American civil aviation market.

Operational history

General use

All export sales of the PC-7 are subject to approval by the Swiss Government, whose authorisation is required prior to any delivery taking place. The sale of combat-capable aircraft has been a controversial matter at times, and political pressure has been applied for PC-7s to be shipped without the fittings for armaments being installed. The Swiss government has occasionally held up or outright refused to issue export licences for some nations, a move which has reportedly led to the loss of several potential sales, such as to South Korea and Mexico.

In addition to its adoption by numerous military customers, the PC-7 has also been used by private customers. It has been certified for civil use by both the Federal Office of Civil Aviation (FOCA) and the U.S. Federal Aviation Administration (FAA) as compliant with regulations pertaining to general aviation (GA) operations in both Europe and the United States. Amongst its uses in the civilian sector has been aerobatic displays.

During the 1990s, the PC-7 Mk.II M was adopted as the basic trainer of the Royal Brunei Air Force (RBAirF) alongside the BAE Systems Hawk jet trainer; the acquisition was seen a key to its expanded operations with fixed-wing aircraft.

During June 2011, the Indian Air Force (IAF) selected the PC-7 Mk.II M as its new basic trainer, signing a contract for an initial batch of 75 aircraft, with an option for buying an additional 38 PC-7 Mk.II Ms; the Indian military had a total requirement of 181 trainers. The fast-tracked decision to procure a foreign aircraft over a domestically developed alternative proposed by Hindustan Aeronautics Limited (HAL) was a controversial one; retired Air Marshal Anil Chopra argued that HAL had no viable design for the role, and that the IAF could not have reasonably afforded the delay involved in the development of such an aircraft. The procurement of an additional 106 trainers under the 'Make & Buy' (Indian) category was repeatedly deferred. In 2017, the maintenance agreement with Pilatus lapsed, resulting in the IAF becoming solely responsible for performing these activities. In 2018, India announced that it had chosen to exercise the option of buying a batch of 38 trainers. However, as of 2020, the additional orders for PC-7 aircraft from IAF were cancelled in favour of the indigenous HAL HTT-40 from Hindustan Aeronautics, the orders for which was placed in 2022.

Combat use

A number of PC-7s were employed by the Guatemalan Air Force in air strikes and for close air support (CAS) during the Guatemalan civil war, starting in 1982, until the end of the conflict in 1996. The PC-7s were typically deployed from the airfield in La Aurora, being armed with a mixture of gun pods and rocket pods.

During the lengthy Iran–Iraq War of the 1980s, amid tensions between Iran and the United States, it is alleged that Iranian officials threatened to arm its PC-7 fleet with explosives and use them to launch suicide attacks against United States Navy (USN) vessels present in the Persian Gulf. Iran reportedly trained a number of suicide pilots and flew some operational missions, training was performed at Bushehr Air Base in Iran and overseas in North Korea. In early 1984, an Iranian attack helicopter AH-1J Sea Cobra was shot down by an Iraqi PC-7 during Operation Khyber (Iranian pilots Reza Moghadam and Mohammad Yazdi were rescued).

In 1994, the Mexican Air Force used several armed PC-7s to attack units of the Zapatista Army of National Liberation during the Chiapas conflict in Mexico. This action was considered illegal by the Swiss government because the aeroplanes were sold for training purposes only, and as result, Switzerland issued a ban on the sale of additional units to Mexico. At the time, the Mexican Air Force was the largest single export operator of the type, and had been seeking to acquire further PC-7s, thus the sales ban was viewed as an economic blow to Pilatus.

During the mid to late 1990s, Executive Outcomes, a private military contractor led by Eeben Barlow, utilised three armed PC-7s (ex-Bophuthatswana Air Force aircraft) to provide close air support (CAS) during its operations in Sierra Leone.

During the late 2000s, the Chadian Air Force reportedly used its small fleet of PC-7s to bomb rebel positions both in their own territory and in neighbouring Sudan. The Swiss government summoned the Chad's ambassador to request an explanation for these reports, as these actions breached the export agreements previously struck for the sale of the type to Chad.

Variants

• PC-7 : two-seat basic trainer aircraft, powered by PT6A-25A engine rated at 410 kW.
• PC-7 Mk.II M : a development of the PC-9's airframe and avionics, retaining the PC-7's wing to mount external stores. Powered by PT6A-25C of 522 kW rather than more powerful PT6A-62 of PC-9. Developed for the South African Air Force (SAAF), and known as the 'Astra'; the aircraft is a hybrid PC-7 and PC-9, either a PC-7 'Heavy' or a PC-9 'Lite', depending on point of configuration.
• NCPC-7 : upgraded version of the standard PC-7 with fully IFR glass cockpit avionics, developed for the Swiss Air Force. The designation NCPC-7 has been provisionally used in the Swiss Air Force to differentiate modernized PC-7s (NC for New Cockpit) from those which were not yet done. It was removed after the improvement of the last of the 28 aircraft in 2009. Consequently, all the Turbo-Trainer took again the designation PC-7.
• PC-7 WE: upgraded variant of the NCPC-7 for the Swiss Air Force that includes: modification of the communication system, a TCAS (traffic collision avoidance system), ADF system extended (radiocompas), complete disassembly of the avionic and antennas to check for problems, complete disassembly and reassembly of the cables and repairs.
• PC-7 MKX: an updated version of the PC-7 Mk.II, with new avionics, cockpit displays, and integration with the ground-based training system (GBTS). The GBTS includes computer and simulator technology, along with new tools such as virtual reality and mixed reality. PC-7 MKX was announced at the Dubai Airshow in November 2021.

Accidents and incidents

• The South African Air Force (SAAF) grounded their fleet of PC-7 Mk.II M aircraft after a crash on 15 January 2008. The aircraft went down shortly after takeoff from Overberg Air Force Base in the Western Cape Province. SAAF Lieutenant-Colonel Chris Meiring, 58, died shortly after the crash. The aircraft was flying to Langebaanweg Air Force Base for maintenance but shortly after takeoff it rolled and flew into the ground. The cause is believed to have been a structural problem.
• In March 2010, a pilot was killed when his Royal Malaysian Air Force (RMAF) aircraft exploded and caught fire in midair during a solo airshow. This is the fifth accident involving Royal Malaysian Air Force PC-7 aircraft.
• In June 2010, two Mexican pilots were killed when their Mexican Air Force PC-7 crashed after taking off from Pie de la Cuesta, a district in the resort city of Acapulco, Mexico. The PC-7 crashed into the sea near Acapulco.
• On 20 October 2011, two PC-7s of the Botswana Defence Force were involved in a mid-air collision over Letlhakeng 100 km west of Gaborone. Two of the four aircrew involved were killed in the accident.
