NAVSUP WSS Philadelphia seeks eligible contractors to repair one P8 aircraft Window Heat Control Unit for New Zealand. The government intends to solicit only S&K Aerospace under FAR 6.302-1 because it lacks the data needed to perform the repairs or manufacture the item. Responsible sources may identify interest and provide capability statements, but this notice is not a request for competitive proposals. Source approval is required, and the government will not delay award while source approval is pending. Non-approved sources must submit the information detailed in the NAVSUP-WSS Source Approval Information Brochure for Repair with their proposal.
