I was planning on adding access panels forward of the windshield anyway (seems to be a common mod), so I was happy that Van's released an official OP kit for this (OP-43). It works pretty much like all access panels - match-drill the doublers, cut the skin, then file it all down until it fits well:
|Doublers and covers atop the forward fuselage top skin|
|Forward fuselage top skin match-drilled for the doublers and marked for cutting|
|Forward fuselage top skin after cutting, with doublers and cover on|
Whenever I do the next batch of primer, I'll include these so I can start riveting them (though I won't prime for rivet the top forward skin for quite some time still).
Total forward fuselage access panel rivets: 0
Total forward fuselage access panel time: 4.3h
