1. Altimeter BNO Justification - CO Sgnd_Redacted.pdf

This is a Single Source Justification document for the procurement of Larsen Brusgaard (LB) Altimeters/Model-Alfa for the 48th RQS pararescuemen at Davis-Monthan Air Force Base. The document, dated April 2021, justifies a sole-source acquisition through 355 CONS/PKP for Air Force-approved altimeters used in skydiving operations.

The justification explains that the LB ALFA model is currently utilized by the 48th RQS and is specifically approved on the Air Force Personal Parachute Program approved for use listing. Per AFI 10-3503, Air Force rescue operators are required to wear altimeters during military jump operations/missions, and the ALFA Military Altimeters are specifically authorized for use with military static-line systems and free-fall systems. While market research indicates multiple small business vendors could supply AF-approved altimeters, the unit already owns the charging/transport cases for this specific brand, and selecting a different brand would cause non-standardization issues. The contracting officer determined on February 27, 2025, that only a single source is reasonably available for this procurement in accordance with FAR 13.106-1(b)(1).
