OTTO Instrument Service is an aircraft instrument and accessory company. It repairs, manufactures and distributes aviation components. The company provides maintenance, repair and overhaul services for original equipment manufacturers, commercial air transport, cargo and freight operators, regional, corporate and private operators, and military and defense operators around the world.

OTTO has capabilities on thousands of part numbers. It holds full class ratings for mechanical, electrical, gyroscopic and electronic instruments. Its ratings also cover mechanical, electrical and electronic accessories, and communication and navigation radio components. It also holds limited pulse radio and airframe ratings. OTTO supports components on Boeing, McDonnell Douglas, Airbus and Bombardier aircraft. It also supports business and general aviation types from Beechcraft, Cessna, Gulfstream, Lear, Mooney and Piper.

OTTO offers DER repairs. It develops and obtains FAA Designated Engineering Representative approval for repair specifications. The aim is to keep the part serviceable while limiting any change to existing maintenance instructions. It also offers Honeywell licensed repairs. Its MRO integrator service finds and qualifies repair suppliers, negotiates prices and turnaround times, and manages those suppliers through the repair cycle.

OTTO manufactures parts to customer drawings. Its ISO 9001 and AS9100 quality systems cover manufacturing for military and commercial aircraft, and for other applications too. It builds custom parts, tooling, test equipment, components and wiring harnesses. It also gives support for FAA Supplemental Type Certificate projects, FAA PMA manufacturing and engineering.

OTTO is a distributor for several original equipment manufacturers. It keeps a pool of rotable components, so it can supply new and overhauled units from stock. It also sells new detail parts. Custom range marking of new instruments is available for a specific aircraft and configuration. The website lists authorized distributor roles for several brands, including Sandel and Sigmatek.

OTTO began in 1946 in a 120 square foot leased office at Rubidoux Airport in Riverside, California. Its repair station certificate was issued in 1946 and was changed to WE2R263L in 1990. The company is a member of industry groups including NBAA, NATA, HAI, AIA and PAMA.
