I'm confused, A44WE is not the FAA TCDS, comes up as not a valid number, A16WE is, or at least per the FAA RGL.EASA number?
14 CFR 25.672 came out with Amdt. 25-23, Eff. 5/8/70, so it shows up (somewhat) in Type Certification Basis, (737-300 Series Airplanes), Type Certification Basis, (737-400 and 737-500 Series Airplanes),
*Applicable only to new or major modified structure or to new systems and components unique to the 737-400, and 737-500 series airplane with respect to the existing Model 737-200 Series airplane.
737-600, -700, -800 (Cont’d.) Certification Basis: A. 14 CFR Part 25 of the Federal Aviation Regulations as amended by Amendments 25-1 through 25-77 with the exceptions listed below
So for those aircraft it is a valid rule
