Abstract :
This paper addresses the selection and qualification
of helicopter firms for various types of maintenance on overhead
lines. The paper is not intended to provide specific recommendations
pertaining to the use of helicopter for construction of lines.
The paper also includes a number of sample questionnaires that
may be used to assist utilities in the preparation and implementation
of helicopter contracts for the following tasks.
• Patrol, inspection, and transportation;
• Line maintenance (i.e., component repairs, modifications, securing,
or replacement).
The guide may also be used to periodically review the quality of
standards for existing airborne contractors. Therefore this paper
provides guidance on items they need to consider when selecting a
helicopter contractor for the purpose of performing line work on
or near overhead lines including patrols.
This guide includes four (4) parts:
• Contractor qualifications;
• Helicopter contractor expression of interest (example);
• Utility company helicopter contractor inspection checklist
(example);
• Pre-trip inspection report (example).
