This is a non-competitive procurement for a specific aircraft engine seal (NSN 2840-01-308-7046), with GE Aviation currently identified as the only approved source. Qualification requirements apply, and award will only be made to sources that meet these requirements at the time of award. Interested offerors are encouraged to submit Source Approval Requests (SARs) promptly, as the government is not required to delay award for pending SARs. No budget amount or performance location is specified in the description. If competition emerges, a revised solicitation with additional sections and first article requirements will be posted.
