How to specify aviation access equipment without wasting a month

Step 1 — Describe the work, not the product

The single most expensive mistake in this category is starting with a product name. "We need a B-1 stand" tells a supplier nothing about whether a stand is the right tool. Start here instead:

• What is being accessed — the actual panel, port, section or task
• What the technician does once they are there, and for how long
• What they carry up with them
• How it is done today, and what is wrong with that

Step 2 — Get the height right

Working height means the height of the work, not the height of the deck and not the height of the aircraft. A deck at the work height puts the task between roughly waist and shoulder level for the person doing it. Too low and they reach overhead all day; too high and they lean out over a rail.

If you cannot measure it, estimate it and say so. A supplier who cannot work from an estimate cannot work.

Step 3 — Decide: stairs, platform, or both

A stair gets you to the work. A platform lets you do the work. If people will stand at height with tools in both hands, you need a platform — even if what they climb to reach it is a stair. The moment somebody works from a stair tread, the specification failed.

Step 4 — Count the people and the tooling

Deck size and rated capacity follow from how many people are up there at once and what is up there with them — toolboxes, parts, a panel that has just come off. Rated capacity is not "the weight of one person." Give the realistic worst case.

Step 5 — Contour or standoff

Does the deck need to nest against a curved surface, or can it stand off? Nesting means cutouts, non-marring contact faces, and usually custom fabrication. Standing off means a gap, and a gap has to be guarded or bridged. Decide deliberately — the default answer of "we will just be careful" is how people fall.

Step 6 — Mobility, honestly

Does it move between jobs, or live in one bay? Mobility costs footprint, weight and money, and most stands bought as mobile end up parked. If it moves, ask: can one person move it, loaded, on your actual floor? If it crosses a ramp, it needs tow provisions and different casters.

Step 7 — Facility constraints are design inputs

• Hangar door height and any low structure on the path
• Floor loading limits, and whether floor markings or embeds are in the way
• Where it is stored between jobs — a platform you cannot store gets damaged
• Whether it must break down for transport

Step 8 — Ask what standard the build is dimensioned against

Not "is it OSHA compliant" — that question gets a yes from everyone. Ask which standard, for which element, and ask to see it on the drawing. For this equipment the relevant ones are generally:

Standard	Covers
OSHA 29 CFR 1910.23	Ladders and stairways — tread geometry, rise and run, stair rails
OSHA 29 CFR 1910.29	Fall protection systems and criteria — guardrails, handrails, toeboards
ANSI-ASC A14.7	Mobile ladder stands and mobile ladder stand platforms
OSHA 29 CFR 1910.28	Duty to provide fall protection — the obligation that drives the whole purchase

Compliance is a function of the configuration you order and how it gets used on your floor. A supplier who puts a blanket compliance badge on a web page and nothing on the drawing has told you exactly how much thought went into it.

Step 9 — Get the aviation-specific options named explicitly

Non-marring contact points, FOD-conscious construction, deck surfaces that do not drop hardware onto the aircraft below, tow provisions if it crosses a ramp. In general industry these are options. Around an airframe they are the specification.

Step 10 — Then, and only then, ask for a price

With steps 1 through 9 answered, every quote you receive will be for the same thing, and you can compare them. Without them, you are comparing a stock stand to a custom platform to a lift and wondering why the numbers are three times apart.
