Anyone know what the very first airworthiness directive was?
Right. What’s a cubit?AIRWORTHINESS DIRECTIVE
Model Icarus-I
Date: -MMCII
COMPLIANCE:
With ten flight hours:
1. Replace wax used to affix feathers with heat-tolerant wax per Greek Army standard SDCC-A
2. Add markings to altimeter to consist of a red line at 3,000 cubits.
3. Add placard to panel: "AIRCRAFT MUST NOT BE OPERATED IN A SOLAR HEATING SITUATION"

Correct and very quickBill Cosby

The cubit is an ancient unit of length that had several definitions according to each of the various different cultures that used the unit. These definitions ranged between 444mm and 529.2mm. The unit was based on the forearm length from the tip of the middle finger to the bottom of the elbow.Right. What’s a cubit?

Cosby was so funny. His dentist routine always has me laughing hard.
It’s too bad he turned out to be so “rapey”.
I guess your answer is that nobody really knows. The earliest one I can find on the web is AD 41-47-01, for DC3s. It requires rebalancing of control surfaces each time they are overhauled or repaired.

If I recall, back in the early days of the CAA they had Airworthiness Maintenance Bulletins which I believe morphed into ADs. If anyone has a subscription to an AD service it would make a good question to their tech support guys.Whether there were older ones that were superseded or cancelled, I don’t know.

Correct. But I remember meeting several tech geeks from Avantext or Adlog or something similar at a convention in the early 90s just as personal computers were getting cheap. I could be wrong but I recall they were having problems writing code to pull out historical ADs from the FAA data base or something. They added the 1st ADs came out around '38-'40 when the CAA was created as a separate entity. Before that I believe they were called Airworthiness Maintenance Bulletins. So your '41 AD would line up with that if I remember the conversation correctly.Well the CAA became the FAA in 1958 which was 17 years after the 1941 AD so something was carried over from one to the other.

That is the oldest “current” one that the FAA shows online. Whether there were older ones that were superseded or cancelled, I don’t know. I do believe that 1941 was the first year for ADs and there were not many issued in the early years so that might indeed be the first.
