From the Contract Specialist: The buy will be revised with a changes to the PWS in the solicitation attachment. The first answer the customer provides is referencing this revision. From the Customer: The first question from is addressed in the PWS (electronic). Our maintenance officer contacted NAVAIR and there is no standard re build and test procedures. They indicated to us that each engine shop will use their own test procedures. Here is their response: Lakehurst never developed an overhaul/re-build instruction for these engines. Typically a small engine repair shop has their own test procedures post re-build that would be more than sufficient. Once the engine is installed we would follow new engine start procedures and perform the applicable E28 cert checks: stall and retract. WRT to the last question, we are not committing to more than 1 at a time, as written in PWS

From Customer: Exposed engines will be delivered as pictured, bolted to a pallet, with attached tag numbers for reference. Wisconsin V465 repair manual and engine specifications attached. From Contract Specialist: When Buy is re-posted with solicitation amendment, photos, manual and specifications will be provided.
