Dear Mr. Citrolo:

This is in response to your letter of December 1, 1986 requesting a clarification of 29 CFR 1926.551 for line maintenance on a de-energized transmission line.

The use of helicopters is not specifically prohibited by 29 CFR 1926.551 or by 29 CFR part 1926, subpart V. However, the company must comply with all of the applicable requirements in 29 CFR 1926.551 and 29 CFR part 1926, subpart V, including 29 CFR 1926.950(c) for clearance from any nearby power lines that are not de-energized.

If we can be of further assistance, please let is know.

Sincerely,



John B. Miles, Jr., Director
Directorate of Field Operations
