Voodoo, you are a quick learner! One detail I did not mention before and you found, is that it is whoever returns the airplane to service - IA, Repair Station - or "AME" as in EASA terminology, determines whether a Repair or Alteration is Major or Minor. Another "what could go wrong with...
Looks like you have done some research, which will help to fend off the trolls.
This document delineates what MUST be STC'd:
https://drs.faa.gov/browse/excelExternalWindow/5394780C328E120C862581600045B7E7.0001
There is still a lot of art in "interpreting" this document (only the FAA is...
The Type Certificate Data Sheet (TCDS) is your source. If the aircraft model is certified for ditching, it will say so (Order 8110-4C, Chapter 3, paragraph 3-3.b.(22)(c)). Some more recent TCDS's will even say if it is not, for instance, on the Cessna (oops, Textron) model 680: "14 CFR 25.801...

for a whole kit, suitable for long term storage. All the components, and thorough instructions. Also some good rabbit tunnels to go down and get lost in (engine manufacturer service bulletins). Or try...
As a practical matter, nearly all PMA's by Identicality per a Licensing Agreement are made by the supplier to the OEM. Either the OEM does not want to bother with the support supply chain, or the supplier made permission to sell in the aftermarket part of the original agreement of selling to...
Yes the requirement applies to all Part 25 aircraft with Certification Bases Amendment 25-64 and after. And most airliners with earlier Cert Bases used in Part 121 operations (date thresholds apply).
As a practical matter, a seat manufacturer is not going to design different seats for above...
SparWeb, I would partially disagree with the assertion that getting DT authority is harder now than 20 years ago. Current requirements are in Order 8100.8D (10/28/2011) Table 4-1, page 4-7:
This reads the same as Order 8110.37C (9/20/98), before appointment requirements were moved out at...
No further approval would be needed to install a PMA part on any particular serial number of a model listed for the PMA.
To install a PMA'd part on a model NOT listed, then yes, installation data and an approval for it would be needed. But at least manufacturing approval for the part is...
Sounds like the two positioning up-downs before and after the middle of the mission may be a bigger effect than you realize.
Bird strike on the windshield (25.775, if you have to comply) is a one-time discrete event, so while the mission may statistically be "in the muck" for more time, the...
There's a recent "publication" from TAD, "Lists of Part 25/26 Rules and Their Associated Advisory Circulars and Policy Statements" that lists each regulation:
https://www.faa.gov/aircraft/air_cert/design_approvals/transport/rules_acs_policy/
Best part is, there are hyperlinks to the various...
CVE actually stands for “Compliance Verification Engineer”, it is an independent checking function of the showing of compliance. Similar to some of the Administrative DER duties here in the U.S. FAA system. They perform a check that all regulations in the Certification Plan have been complied...
Greetings,
Cabin outfitting and subsequent modifications are not required to be STC’d (or part of the TC). They may be done by engineering approval - DER 8110-3 or ACO approval.
The history is that a decade or so ago, FAA Aircraft Certification and Flight Standards got together to decide what...
Actually they are (or should have been!), keep looking through Chapter 4/5 for examples. And if not, look at another aircraft manual. In most cases these types of parts have "super fatigue life" as you call it, just as a matter of good design practice. Either intentional or by luck. And...
Good evening,
My first suggestion would be to use an internal doubler for the connectors, then separate internal doublers (nutplate strips) for the attachment screws.
But knowing nothing about your geometry, let's assume your hands are tied so then allow me to answer your questions directly...
What are the thicknesses of the 3 layers? Also what type of fasteners? Bolt hole EC is typically used for deep holes, i.e., each thickness is similar to or greater than the hole diameter. Also the "3 layers" statement piques my interest, understanding that may be just a 'for instance'...
