Jetstar Prototype Data



Original Certificate of Airworthiness - Issued three days before First Flight

What's In a Name?

What is the Jetstar?  Is it a Model L-1329?  or L-329?  or CL-329?  or just 329?  Is is Jetstar?  or JetStar? or Jet Star?

Well, here goes a try:

The FAA considers the airplane, as defined by its Type Certificate, to be a Lockheed Model 1329 airplane, with variants given dash numbers, such as the Models 1329-23A, -23D, -23E and -25.

The U.S. Air force, that operated them as C-140, VC-140, and VC-140B airplanes, refers to them as Model 1329.

Lockheed issues Service Bulletins for the airplane under the Numbering System 329-, such as 329-302 issued  July 9, 2003.

There are two data plates on the Serial Number 1001 airframe.  One shows the Manufacturer's Model as CL-329, and the other, just below the first, shows Model L-329.  See photos below.

The "Code Breakers" at the Skunk Works who we've talked to say that Kelly Johnson used to love to play with his model numbers, and the CL-329  N329J decodes as follows:

CL -    Kelly's first two initials (Clarence Leonard)
329 -   the number of days Kelly gave the Skunk Works to design, manufacture, and fly the airplane*
J -       Johnson - Kelly's last name.

* The number usually used is 241 days, so this piece of code is still, perhaps, encoded !

So...... now you know !  or do you?  It's a CL-329 /  L-329 /  L-1329 /  329 /  1329 Aeroplane.
