• Aircraft Maintenance Engineer → Aircraft maintenance engineer
• Aircraft Maintenance Engineer (Canada) → Aircraft maintenance engineer (Canada)
• Aircraft maintenance engineer → Aircraft maintenance engineer (disambiguation)

– Per MOS:JOBTITLES and MOS:DOCTCAPS (and WP:NCCAPS more generally), and to be WP:CONSISTENT with around 99% of occupational article titles. This is not a proper name, it's an occupational descriptive phrase. N-grams show that the lower-case form dominates in source material [1] . This is most often capitalized in marketing materials for training programs, in governmentese documents, on business cards, and in other situations in which over-capitalization runs rampant. There are a number of other occupational articles like this that need down-casing, but experience tends to show these topics should be taken in clumps not a huge mass-move).  — SMcCandlish ☏ ¢ 😼  10:38, 26 August 2022 (UTC)__DTREPLYBUTTONSCONTENT__-->__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20220826103800","author":"SMcCandlish","type":"comment","level":1,"id":"c-SMcCandlish-20220826103800-Requested_move_26_August_2022","replies":["c-Steelpillow-20220826132400-SMcCandlish-20220826103800","c-Steelpillow-20220826132000-SMcCandlish-20220826103800"]}}-->

Oppose. There is a distinction between a job description and a professional qualification or title. This is made very clear in the style guides referred to; please read them properly before invoking them here. One example given is the distinction between the office of president of the US and the incumbent's title as President of the US. Another is the use of republican to denote a political creed but Republican to denote a particular political party of that name. As an article-based example here, we have one on the military rank of sergeant major and also many specific articles, typically nationality-based, on capitalised Sergeant Major of the Army, etc. Turning to the present proposal, it is internationally recognised by the ICAO that the aircraft maintenance technician, engineer and mechanic are synonymous, so one lower-case article is sufficient to cover all of them. But the nationally-based professional qualifications and accompanying titles of the capitalised Aircraft Maintenance Technician, Aircraft Maintenance Engineer and so on differ, just as the roles and responsibilities of the qualified AME differ between Canada and most other Commonwealth nations. To take just one example, the Aircraft Maintenance Engineer (Canada) is qualified to carry out the tasks of the aircraft maintenance engineer, technician or mechanic, but may or may not do so; the Canadian AME's principal responsibility is to approve such works as airworthy, on behalf of the relevant government minister. By contrast the American AMT carries out exactly the same work but must defer to a Designated Airworthiness Representative – Maintenance (DAR-T) or other delegated appointee for certification. Capitalisation is how the professional world maintains these distinctions in text when it needs to, which is not that often - hence the misleading stats gathered by the OP. Subjective rhetoric over "needing" to "correct" endless articles sadly displays an editorial PoV bias which fails to respect the very guidelines it cites. — Cheers, Steelpillow (Talk) 13:20, 26 August 2022 (UTC)__DTREPLYBUTTONSCONTENT__-->__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20220826132000","author":"Steelpillow","type":"comment","level":2,"id":"c-Steelpillow-20220826132000-SMcCandlish-20220826103800","replies":["c-Dicklyon-20220826181200-Steelpillow-20220826132000"]}}-->

I presume that edition is still current. Steelpillow, if you want the title to refer to the certification, the article title will need to express this directly; e.g., "Aircraft Maintenance Engineer Certificate". But your case is further disadvantaged in that there's no single, international certificate. The term is generic.

• Support per cited sources and more. The first, most-cited ref, on the Canadian one that defines this license, says "The standards set out in this Division apply in respect of aircraft maintenance engineer (AME) licenses issued pursuant to CAR 403.03." The capitalized form is found there only in title-case headings. Similarly, in the main article this ref says "An aircraft maintenance engineer (AME) is a licensed person who carries out and certifies aircraft maintenance." and "A licensed aircraft maintenance engineer (L-AME) is an AME with an inspection authorization." Wikipedia uses sentence case for titles, per WP:NCCAPS. The cited sources clearly show that capitalization is not necessary.

Per WP:NCCAPS, "Do not capitalize the second or subsequent words in an article title, unless the title is a proper name" (my bold). MOS:JOBTITLES and MOS:DOCTCAPS give examples of such proper names, as I already pointed out above.

These job titles / certification titles are clearly not proper names. It's important to understand the linguistic definition of a proper name. I also don't see support for capping these titles in MOS:JOBTITLES or MOS:DOCTCAPS. The "formal title" part of MOS:JOBTITLES is for "a specific entity", i.e. a title held by only one person at a time, such as the president or prime minister or secretary of state of a specific country or the pope (i.e. office-holder as pre-eminent leader of a specific religion), the governor of a specific place or the mayor of a specific city, not a job title or certification concurrently held by thousands of people. —⁠ ⁠BarrelProof (talk) 20:44, 27 August 2022 (UTC)__DTREPLYBUTTONSCONTENT__-->__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20220827204400","author":"BarrelProof","type":"comment","level":5,"id":"c-BarrelProof-20220827204400-Steelpillow-20220826185900","replies":[]}}-->

• Comment To expand on my previous comments, treating all these titles as synonyms is unhelpful. The International Civil Aircraft Authority notes that (lower-case) terms such as aircraft maintenance engineer, aircraft maintenance technician and aircraft mechanic are all synonymous. It leaves individual nations to call them what they will. Nobody is arguing against that. But the roles and responsibilities of some licensed engineers are wider than others. For example the Canadian AME combines the roles of the American AMT (technician) and DAR-T (appointed inspector). We need some way to disambiguate these article titles, and capitalisation is one simple option. Meanwhile, the Transport Canada example given above is no overly helpful. The professional association of Aircraft Maintenance Engineers of Canada (AMEC) does capitalise the licensed Aircraft Maintenance Engineer. There is an ongoing issue between TC and AMEC over the status of their AMEs, mostly unpublished but here is a useful background document. In short, all these one-liner opinions here which fail to discuss, or even acknowledge, such issues are not helpful in reaching a balanced conclusion. — Cheers, Steelpillow (Talk) 05:57, 29 August 2022 (UTC)__DTREPLYBUTTONSCONTENT__-->__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20220829055700","author":"Steelpillow","type":"comment","level":2,"id":"c-Steelpillow-20220829055700-Steelpillow-20220826140200","replies":["c-BarrelProof-20220830173100-Steelpillow-20220829055700"]}}-->

I don't think the lack of capitalization indicates "treating all these titles as synonyms". Any ambiguity is going to be inherent in the terms themselves, regardless of whether they are capitalized or not on Wikipedia, and any necessary disambiguation would need to be accomplished within the article or in parentheticals. —⁠ ⁠BarrelProof (talk) 17:31, 30 August 2022 (UTC)__DTREPLYBUTTONSCONTENT__-->__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20220830173100","author":"BarrelProof","type":"comment","level":3,"id":"c-BarrelProof-20220830173100-Steelpillow-20220829055700","replies":["c-Steelpillow-20220830185700-BarrelProof-20220830173100"]}}-->

You are right it doesn't. But what does is the ICAO standard treating them explicitly as synonyms. See for example the ICAO International Standards and Recommended Practices, Annex 1 to the Convention on International Civil Aviation: Personnel Licensing, Chapter 4. Licenses and Ratings for Personnel Other than Flight Crew Members.[2]: "4.2 Aircraft maintenance (technician/engineer/mechanic) Note.— The terms in brackets are given as acceptable additions to the title of the licence.

The case where someone is trying to use capitalization to indicate some kind of "officialness" or special meaning is a common controversy around here, and it is not hard to find examples of article titles that use such capitalizations. But I think there is basically no support for that in the Wikipedia policies and guidelines, at least unless it can be shown that a term is consistently capitalized in independent reliable sources. Declarations by authorities, such as governments or certifying institutions, are usually not persuasive. —⁠ ⁠BarrelProof (talk) 17:28, 31 August 2022 (UTC)__DTREPLYBUTTONSCONTENT__-->__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20220831172800","author":"BarrelProof","type":"comment","level":5,"id":"c-BarrelProof-20220831172800-Steelpillow-20220830185700","replies":[]}}-->
