The Aircraft and Owner

This Beechcraft 1900D was recently ferried all the way from from South Africa. It will be followed shortly after by two additional 1900D aircraft. They will all join a growing fleet of 1900Ds that are busy supporting Western Canada's booming oil patch. Maxcraft Avionics worked on the aircraft at Langley Airport (CYNJ) alongside Langley Aero Structures.

The Story

The job grew larger as more discrepancies were discovered. Many of the issues stemmed from equipment not being originally installed to Transport Canada safety standards. In other cases lack of documentation was a factor.


Although the existing KLN-90B GPS installation was poor quality and had not been properly integrated, the equipment was retained because it was the same type used on the operators other aircraft. The system was completely rewired/re-installed to meet IFR operational standards in accordance with the operators STC approval.
