The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the manufacture of aircraft towbars, classified as critical safety items. This procurement is a sole source requirement, necessitating engineering source approval from the Naval Air Systems Command, as the government lacks sufficient data to contract with other sources. The towbars are essential for aircraft ground servicing, and any company seeking to participate must submit a Source Approval Request along with their proposal, including detailed documentation of their manufacturing capabilities. Interested parties should direct inquiries to Alexis Healy at alexis.k.healy.civ@us.navy.mil or by phone at 215-697-1143, with proposals remaining valid for a minimum of 120 days following submission.
