AMOS

AMOS is a maintenance, repair and overhaul system for aircraft operators and maintenance organisations, built from core and optional modules and extended by AMOSeTL for the electronic technical logbook and AMOSmobile for line maintenance execution and stores handling.

Aircraft maintenance software carries an unusual burden. Every component has a life limit measured in flight hours, cycles or calendar time, every task has an interval mandated by the manufacturer or the authority, and an aircraft may not fly if any of them lapses. The system is therefore not tracking work but enforcing airworthiness, and an error does not produce a bad report, it grounds an aircraft or, worse, does not.

The electronic technical logbook replaces the paper record a crew signs after every flight, capturing defects and completed work at the aircraft. Digitising it removes the delay between a defect being noticed and engineering seeing it, which on a paper process can be a full rotation.

Mobile stores handling matters more than it sounds. Maintenance stops when a part cannot be found, and an engineer holding a device that can locate and issue a component avoids the walk to a desk that is how hours disappear on a line.
