Any reason for the odd shaped access panel on the TE Flap canoe fairing of the B752.It could have been any shape but why this [similiar to a bowtie]....Any History on it.

Hah! I've got nothing for you, but it's certainly an interesting find!

Maybe access for flap lubrication?

The Access panel is for providing access,but the query was why the odd shape,why not just a simple Rectangular one....

Mel,

I took a closer look at one of our 757's last night. That access cover falls in the middle of a seam on the canoe fairing. There is an internal doubler and the fasteners in that doubler follow the perimeter of the cover. My guess would be it's a trade off for strength. The small round area in the center is the only part that really disrupts the structure. Plus you save a few screws and nutplates.

My guess is for simple inspection. Pull the panel, shine a light inside and inspect something. Just speculation.

Quick access to lubrication fittings? That fairing contains drive mechanism for the aft flap.

The panel is for a the bolt that holds the aft end of the canoe fairing. I can't recall if it has lube point on the end or just fittings inside. I think it is the strange shape due to the internal structure. With the pivot motion I don't think there is room for more fasteners. BTW installing that fairing is a real pain. Hardest one on the wing.

Will check the same out on the next major Check......One among a few things to clarify on.
