Heliproducts Industries completes full upgrades on this Airbus Helicopters AS355N, complete with full 12 year major inspection. The 12-Year Inspection effectively resets the inspection cycles to zero and allows the aircraft to be completely updated by incorporating all existing factory configuration changes and Transport Canada, Federal Aviation Administration, or EASA requirements.

Having the 12-Year Inspection performed at Heliproducts offers numerous advantages, including attention to all aircraft systems, equipment and controlled timing of delivery. We offer full in house capabilities and including factory trained technicians. Within our Vancouver BC region, we also have immediate access to Airbus Canada, Turbomeca Canada, Vector Aerospace, Heli-One and other cooperative OEM / MRO centers.
Operators can count on high quality inspection and repairs with quick turnaround times due to pre-planned parts supply coordination and advance scheduling of facility resources and personnel. Customer-requested equipment changes and upgrades can also be pre-planned.

The AS 355 N is a twin-engine helicopter. It is driven by two Turbomeca ARRIUS 1A engines of 520 hp each (388Kw) and is equipped with a FADEC (Full Authority Digital Control) system for easy and safe piloting. The performance of its engines makes the AS 355 N the ideal twin-engine helicopter for all transport operations over urban areas, mountains or water by day or night. Particularly light for a twin-engine aircraft, it is ideal for precision aerial work.
