The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the repair and modification of the Main Blade Assembly, a critical component used in helicopter rotor systems. The procurement is a sole source requirement, indicating that the government does not possess sufficient data to contract with any source other than the current supplier, and all repairs must adhere strictly to approved procedures outlined in the Statement of Work. This contract is essential for maintaining operational readiness and reliability of naval aviation assets. Interested contractors must ensure they are an approved source and submit the necessary documentation as specified in the NAVSUP WSS Source Approval Brochure, with inquiries directed to Jacob Wells at jacob.r.wells1@navy.mil or by phone at 215-697-1227.
