I'm chasing details of an STC SA3458WE that refs Volpar drawing list 5300, rev B of 6/28/77.
Can anybody help in my search? To my recollection Volpar is long in the history books. Any source of Volpar dwgs?
Thanks for any comments.

Hi all,
We are considering minor exterior (aerodynamic) changes to a nose radome. Any leads as to how this will/might affect the pitot (total pressure) probe that is slightly aft of the radome. We are talking Vne appx 250kts. Any reasonable measure of probe standoff distance to fuselage...
Hi all, Looked at some impact damage on a wing LE of a TBM700 yesterday and the a/c is assembled with rivets with three small raised dashes on the head as a rivet identifier. Typically on US a/c, as you all know, it would be a single dimple identifier for an MS20470AD rivet in this...
Hi All,
Can anybody lead me to MIL-HDBK 23, with a title something like Sandwich Construction??

Any help will be appreciated, thanks.

Hi all, Can somebody steer me to guidance on fuel tank capacity requirements when doing an engine upgrade? For example take out an A65/65Hp and put in an 0-235/118Hp. The original 13 gal tank is not quite adequate for decent ops. Is there some rule for Part 23 aircraft? Thanks for your...
I'm considering working with a client installing an avionics box in the panel of his EC130B4 machine. We hope to do it initially under a Field Approval/337 and later an STC.
I need IPC or SRM details of the panel structure and local stock materials as well. Can this astute group of engineers...
Doea anybody know of a pressurized "experimental" aircraft?
Not a TC'd airplane now operating in Special/Experimental airworthiness category or a factory built machine hoping to get its TC sometime in the future. I'm thinking more like a Glasair or Cirrus that was amateur built. Maybe even a...
Can somebody steer me to the FAR (Part 23) that calls out instrument panel orientation to the aircraft major axes? Attitude/gyro instruments want to be oriented perpendicular to longitudinal axis but what about the basic panel??
Comments appreciated, Thanks JQCF1
Has anybody heard of bending sheet stock (.063 5052-H32 Aluminum)with grain direction on the diagonal? Local sheet metal shop (not an aircraft shop) experienced cracking on folding up a simple bracket. The bracket is like an upside down 6"long x 4"wide x 2"high box but has integral attaching...
Hi All, I have Bruhn, Roark, Peery, Hoerner etc but still need guidance and references for some hand calc structural issues from time-to-time. From variuos forums on Eng-tips I see suggestions for Niu, Flabel and Megson for structures to add to my library. I'd like your astute comments for...
Hi All,
This is not a repair but an access hole to be put in belly shell of a vintage Bell 206 helo. Say 4" x 6" for discussion purposes with radiused corners in flat honey comb floor and say 1" thick with .025 al facings on H'comb panel.
Current thoughts are to reinforce around opening with...
We are installing a tech work station in a small twin a/c.
The work station has a swing out LCD display that obstructs egress down the aisle. Current two pip pin scheme requires too many motions in an emergency. What we are looking for is plunger type locking scheme that can easily be...
