About Otto Instrument Service, Inc.

Written by GovTribe AI ·

Otto Instrument Service, Inc., a for-profit aerospace component repair and calibration manufacturer based in Ontario, California, operates exclusively as a prime contractor on federal repair and sustainment contracts, with no subcontracting activity. The company competes in full-and-open procurements with no set-aside designation across the vast majority of its work, though it holds one total small business set-aside indefinite delivery contract with the Air Force Sustainment Center.

Otto's customer footprint is heavily concentrated in a single agency. The Air Force Sustainment Center accounts for 38 of 57 total awards (96% coverage of recent activity by award count) and $26.6 million of $28 million in combined potential value — a dominant customer relationship that has anchored Otto's federal work since SAM.gov registration in 2002. Defense Logistics Agency Aviation places smaller volume (4 awards, $528 thousand), the Air Force Materiel Command broader (9 awards, $166 thousand), NASA Armstrong Flight Research Center (3 awards, $12 thousand), and the Naval Supply Systems Command (1 award, $4 thousand) round out the active set. Award frequency has declined in recent years: seven awards in 2022, three in 2023, two in 2024, three in 2025, and one through April 2026.

Otto's capability portfolio centers on repair, overhaul, and calibration of military aviation components. Representative work includes a $628,110.40 delivery order from the Air Force Sustainment Center (March 18–May 19, 2022) for calibration of pressure switches and instruments; a $120,900 delivery order for T-38 altitude computer repair (completed November 2028); and a $69,750 delivery order for altitude computer system repair (October 2025–January 2026). The company holds two active Air Force Sustainment Center indefinite delivery contracts: a total small business set-aside single-award IDC for T-38 altitude computer repair with a $1.5 million ceiling running through November 2028, from which ten delivery orders totaling $748 thousand have been issued, and a non-set-aside single-award IDC for E-3 pressure switch repair with a $210,904.40 ceiling through June 2029, supporting two delivery orders of $28,323.20 combined. Four additional Air Force IDC vehicles carry smaller order volume ($6.5 million, $782 thousand, $313 thousand, and $41 thousand respectively). Work is performed at Otto's Ontario facility; the company provides labor, materials, parts, facilities, equipment, disassembly, troubleshooting, testing, alignment, calibration, and reporting services to return serviceable end items to the Air Force fleet.

Otto's award portfolio reflects sustained demand for specialized aerospace repair expertise, though the trajectory has flattened after 2022. The source carries no visible recompete cliff or upcoming contract completions that would surface material recompete exposure in the near term beyond the existing T-38 and E-3 IDC vehicles already in performance.
