Attachment 1 - Salient Characteristics Exhaust Plugs - Redacted.pdf

This is a memorandum from the Department of the Air Force, 97th Air Mobility Wing (AETC) at Altus Air Force Base, Oklahoma, dated 18 February 2026, regarding the procurement of KC-46 Exhaust Plugs. The 97th Aircraft Maintenance Squadron has requested the purchase of KC-46 Exhaust Plugs to support maintenance operations on KC-46 aircraft. The specified product is the LMC18M87 Thrust Reverser Plug Set, part number PW4000, which must be a two-piece set as confirmed by the provided SERD labeled LMC18M87 showing two separate components that form the complete plug assembly with specified dimensions.

The exhaust plugs function as protective components that safeguard aircraft engines from Foreign Object Debris (FOD), moisture intrusion, wildlife nesting, and environmental contamination. The plugs must comply with OEM specifications and technical data to ensure compliance, prevent premature component degradation, and reduce costly maintenance actions or avoidable downtime. The memorandum provides contact information for questions or concerns regarding these specifications, though specific procurement details such as quantity, pricing, delivery timeline, or contracting deadlines are not included in this document.
