June 1989, by then he was already promoted to the rank of Major. All aircraft of the Suriname Air Force undertake border patrols, utility transport and SAR (Search & Rescue) missions from the main base at Paramaribo - Zorg en Hoop and are occasionally detached to Zanderij - Johan Adolf Pengel International Airport, Nieuw Nickerie - Major Fernandes Airfield, Albina Airstrip and Moengo Airstrip. In 1986 anti-government guerrilla activity prompted the government to acquire a pair of Aérospatiale SA.316B Alouette III (SAF-400 & SAF-500) helicopters from the Portuguese Air Force (Portuguese: Força Aérea Portuguesa), formerly registered FAP9350 & FAP9386. In the same year also three Pilatus PC-7's (SAF-111, SAF-112 & SAF-113) were ordered in Switzerland for COIN (Counter-Insurgency) missions. One of the Alouettes crashed and both delivered PC-7s were returned to Switzerland but one was later re-delivered. In 1987 a Bell 205 Iroquois (SAF-300) was acquired from Venezuela and used as a gunship for five years prior to sale to the US as N6594S in 1991. It crashed in July 1987 due to a mechanical failure killing the American pilot Billy Pearson, seriously injuring the American mechanic and four other Surinamese crewmembers. The helicopter was later repaired and back in action. Two CASA 212-400s Aviocar transports (SAF-212 & SAF-214) Garret AiResearch TPE331-10HR turbo-prop engined aircraft were delivered in 1999. One of these two Spanish built CASA 212-400s is a Maritime Patrol Aircraft version (SAF-214) which was modified for the maritime patrol role with a Bendix RDR-1500 surveillance radar. Lack of spares and funding has hampered maintenance and sometimes grounding much of the SAF fleet. In 2012 six experts from Venezuela made an assessment for the Suriname Air Force on the rehabilitation of the Casa 212 airplanes and now the Suriname Air Force has sold them to Fayard Enterprises in the USA. Three single engined Indian HAL Chetak helicopters were ordered in 2009. In a deal worth US$13.4 million with Hindustan Aeronautics Limited [HAL], facilitated through a line of credit from India. The deal was previous rumoured to include the more modern twin engined HAL Dhruv helicopters, but this proved to be wrong. On 26 December 2012 ten technical personnel of the Suriname Air Force left to India to be trained to become certified helicopter mechanics. In 2014 eight helicopter pilots from the Suriname Air Force were trained on operating the HAL Chetak helicopters in Bangalore, India. In 2014 it was
