What 航空整備士 do
An English description is being prepared. Japanese description:
日常点検では、フライト前にエンジン、機体外部の状況、車輪など所定の手順に従って点検を行っていく。コックピットに入り、計器などのチェックも行う。異常が発見された場合には、修理や部品の交換を行う。点検の結果を機長に報告し、出発する航空機を見送る。確認整備士（確認主任者）と呼ばれる責任者が飛行を許可しない限り、飛行機は飛び立つことはできない。
運航が終わった後には、消耗部品の交換や計器のチェックなどライン整備を行う。更には、一定の飛行時間ごとに定時点検を行い、エンジンを取り外して専用の工場で分解して不良個所の交換を行う。また、自動航法装置や自動着陸装置については、防塵装置を施した専用の部屋でコンピュータ機器の保守整備を行う。点検の中でユーザーの立場から航空機メーカーに対して改良や改善を提案することもある。

Today ¥5.98M → in 3 years ¥6.63M → in 5 years ¥7.10M → in 10 years ¥8.44M (10-year range ¥7.25M–¥9.79M). The model assumes pay growth of +3.5% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 航空整備士? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 航空整備士
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
