Field Support

Viking’s team of Field Service Representatives (FSRs) provide guidance and localized assistance to operators of De Havilland Canada aircraft worldwide. We also provide full support for the CL-215, CL-215T and CL-415 aircraft. With expert knowledge and decades of experience on Viking’s seven aircraft types, our FSRs travel to some of the most remote areas of the globe to provide operators with on-site support. From troubleshooting specific problems to mentoring maintenance crews and providing on-the-job-training, the FSR team can accommodate deployments from a few days to more than a year. 

Engineering Services

Viking’s highly skilled engineers work closely with operators and maintenance facilities worldwide to assist with technical investigations, to develop repairs for damages that are beyond the scope of the generic repair manuals and to provide on-site damage surveys and support.

In time-sensitive AOG situations, our Engineering team can also provide after-hours support, which carries additional charges.

See below for information about Viking’s damage reporting procedure.

Damage Reporting

On a daily basis, Viking’s Engineering team works with operators to develop the most efficient repairs for damages that are beyond the scope of the generic repair manuals. The detailed procedures for reporting damages are outlined in the following manuals:

  • DHC-6 aircraft: PSM1-6-3RS
  • DHC-7 aircraft: PSM1-7-3

For damage reporting procedures related to DHC-1, DHC-2, DHC-3, DHC-4, DHC-5, CL-215, CL-215T and CL-415 aircraft, please contact Viking Technical Support.

All repair requests must include a fully completed damage report form and high-quality images (close-ups and overall area) with the following details clearly identified:

  • View or orientation,
  • Station number,
  • Stringer/rib number, and
  • Fastener heads marked with a “+” in a colour that is visible on the paint.

Important: Please ensure that all dimensions are listed in imperial units.

An acknowledgement of receipt will be sent within one to two business days, along with a quotation for the estimated number of engineering hours that will be required to complete the repair design. A purchase order for engineering services in line with this quotation will be required at the start of all projects. Kindly note that the overall turnaround time for repair designs will vary based on a number of factors, including complexity and workload.
