DynCorp International Inc., the largest U.S. contractor in Afghanistan, was warned by Pentagon officials in January that it is failing to adequately inspect and repair in a timely manner potential electrical hazards at U.S. bases, according to a document. DynCorp also filed reports indicating that it fully completed repair work on potential life, health or safety electrical problems “even though parts are on order and the work is not complete,” Lt. Col. David Schoolcraft, a military contracting officer, wrote to DynCorp on Jan. 7 in a formal “letter of concern.”

The Pentagon’s contract oversight agencies have increased their scrutiny of issues related to electrical wiring at U.S. bases in Iraq and Afghanistan after 18 troops were electrocuted in Iraq either in accidents or in connection with faulty construction or grounding of equipment.
