3 months ago I looked into what those two mods are doing. This is a loading order issue. Spidertron Enhancements (SpiderEn) is a red herring - it doesn't make any changes to technologies and isn't at fault. However in this situation, the presence of SpiderEn changes the loading order of IR3 and Lex's Aircraft (LA). IR3 does make massive changes to technologies (it is an overhaul mod so it can't not). But the problem (in my view) lies with LA.
LA has a dependency on SpiderEn which means SpiderEn will always load each of its data stages before LA does. If SpiderE isn't present, IR3 can end up loading after LA. But if SpiderE is present, IR3 is more likely to load before both SpiderE and LA. The presence of any other mod might also have the same effect.
The issue is that LA sets up that "heavy ships" technology with just a few science packs in the data.lua stage (the first of the three data stages). No problem so far. But in the data-updates.lua stage (the second stage), it then conditionally adds more packs to it. If Space Exploration is installed, it adds some kind of SpaceEx related pack. Otherwise, it will always add a production pack and a utility pack, and it assumes that the tech doesn't already have them. This assumption would be safe to make if it was also done in the first stage when the tech was originally created, but because every other mod has a chance to make their own changes to the tech by the time LA runs its second stage, it's not a valid assumption.
If IR3 loads before LA, then it has run its second stage tech pass before LA runs its own second stage. IR3 massively reorganises vanilla techs, but it mostly avoids unrecognised third party techs, including LA's. But one thing IR3 does do is enforce science pack dependencies, i.e. if a tech unlocks a science pack, all of its descendants must use that pack. LA's "heavy ships" tech has a vanilla tech as a prerequisite which comes after production science in IR3, so IR3 ends up adding a production pack to the LA "heavy ships" tech, if and only if it doesn't already have one. But in the other loading order where LA loads after IR3, LA then adds another production pack without checking.
I don't have an easy fix for this but from IR3's perspective, I don't believe it's done anything wrong. LA has left a data stage gap between setting up a tech and then modifying it. It should be checking first before it adds packs to techs which already have them. Every prototype in Factorio is up for grabs by literally any mod installed: if you assume otherwise, you get this kind of problem.
You can work around this by editing your copy of the info.json file in IR3's top level folder and adding "?lex-aircraft" as a dependency. That will force LA to load before IR3, avoiding the issue.

Game will display the following error message, when starting the game with Industrial Revolution 3, Lex's Aircraft and Spidertron Enhancements and its dependencies:
Error while loading technology prototype "lex-flying-heavyship-ships" (technology): Difficulty normal: Ingredient with type item and name "production-science-pack" is registered twice in the technology Modifications: Lex's Aircraft › Industrial Revolution 3 › Lex's Aircraft
The error only appears, if I have all 3 mods enabled. I tested this on a fresh install of Factorio. Not sure which mod cause this, so I will open this issue on the issue trackers of the aforementioned mods as well.
