The Partenair Mystere is a Canadian two-seat, pusher configuration monoplane that was designed by Partenair Design of Saint-Jean-sur-Richelieu, Quebec and intended for amateur construction from kits.Newby-Gonzalez, Tori: 2004 Kit Aircraft Directory, Kitplanes, Volume 20, Number 12, December 2003, page 71. Belvoir Publications. ISSN 0891-1851Downey, Julia: 2002 Kit Aircraft Directory, Kitplanes, Volume 18, Number 12, December 2001, page 57. Kitplanes Acquisition Company. ISSN 0891-1851

Two prototypes were completed and flown and one kit delivered before the project was ended. One customer-built S45 was eventually completed and first flew on 10 November 2015.

Design and development

The Mystere is an all-composite, low-wing monoplane powered by a pusher piston engine. It has a pod and boom configuration with a T-tail and a fixed tricycle landing gear with wheel pants. The cockpit has room for two occupants in tandem with dual controls and a two-piece canopy and windscreen.

The prototype S44 Mystere first flew on 16 November 1996 powered by a Rotax 912 engine. The second prototype S45 was powered by a {{convert|160|hp|kW|0|abbr=on}} Lycoming IO-320 flat-four piston engine and first flew on 4 October 2001.

The kit was to be supplied in three sub-kits made from primer-surfaced parts of low-odour epoxy. The construction time from the kit was estimated to have been 1,000 hours.Downey, Julia: 1999 Kit Aircraft Directory, Kitplanes, Volume 15, Number 12, December 1998, page 61. Primedia Publications.

Variants

;S44 Mystere

:Initial {{convert|80|hp|kW|0|abbr=on}} Rotax 912UL powered version. Empty weight {{convert|700|lb|kg|0|abbr=on}} and gross weight {{convert|1250|lb|kg|0|abbr=on}}, cruise speed {{convert|140|mph|km/h|0|abbr=on}}. The price of the complete S44 kit, including engine in 1999 was US$38,000. Only one prototype was flown.

;S45 Mystere

:Second version with increased power. Acceptable power range {{convert|100|to|160|hp|kW|0|abbr=on}}, with the standard engine a Lycoming O-320 of {{convert|150|hp|kW|0|abbr=on}}. Kit price in 2003, without engine, was US$27,900. Only one prototype was flown.

;S45 Mystere Mark II

:Third version with aerodynamic refinements, an increase in top speed to {{convert|180|mph|km/h|0|abbr=on}} and an increase in gross weight to {{convert|1925|lb|kg|0|abbr=on}}. The engine was raised so that the aircraft could accept a larger diameter propeller and to increase clearance between the tail boom and the propeller. The engine cowling was also re-shaped to smooth airflow into the propeller. These changes were all to reduce the original S45's noise signature. Kit price in 2003, without engine, was US$27,900. Only one prototype was flown and it was the original S45 prototype in a modified Mark II configuration.{{Cite web|url = http://www.aero-news.net/index.cfm?do=main.textpost&id=ccb0e099-a085-4ce1-9b33-7e573c37b5cf|title = Partenair Announces Third Model |accessdate = 24 December 2011|last = Aero News Network|date = 24 July 2003}}

;S45 Mark III RG

:A proposed retractable gear model that was never built. The Mark III was announced by the company in 2003, with a first flight initially forecast for 2004. It was intended to have a shorter wing and accept engines up to {{convert|250|hp|kW|0|abbr=on}} to greatly increase cruise speed.

Accidents and incidents

The prototype Partenair S44 Mystère was involved in a fatal accident on 24 October 1998. While departing Montréal/Les Cèdres Airport, the Rotax 912 engine failed and the aircraft impacted the ground, killing both occupants.{{Cite web|url = http://aviation-safety.net/wikibase/wiki.php?id=23492|title = Occurrence # 23492|accessdate = 24 December 2011|last = Aviation Safety Network|year = 2011}}

This accident led to the aircraft being redesigned as the S45 with a Lycoming O-320 engine replacing the Rotax powerplant. Kitplanes magazine described the subsequent S45 as a "repowered aircraft for better overall performance and reliability".
