Removing a Major Alteration.

Since adding an antenna requires a 337, according to my local FSDO,
another 337 is needed to remove one?
The other thread about removing old antennas will take on a new twist.

OMG this is going to be ugly.

The purpose of a 337 is to document a change in type design. Once modified,
the aircraft airworthiness is based on the data in the TCDS's -AND- the 337
form. Remove the alteration and the "official" airworthiness status has to be
changed via the 337.....unless, as someone mentioned, the original 337 deals
with converting for use as a camera ship (for example) then converting back as
required.

Here is the definition of airworthiness from the Inspectors handbook:
From 8300.10 chg 17 - The Inspectors Handbook

"(2) Airworthiness:
(3) Since “airworthiness� is not
defined in the FA Act of 1958, as amended, or in the regulations, a clear
understanding of its meaning is essential in conducting a violation
investigation. A review of case law relating to airworthiness reveals two
conditions that must be met for an aircraft to be considered "airworthy.�
These conditions a
(a) The aircraft must conform to its type design (certificate). Conformity to
type design is considered attained when the required and proper components are
installed and they are consistent with the drawings, specifications, and other
data that are part of the type certificate. Conformity would include applicable
supplemental type certificates and field approved alterations.

(b) The aircraft must be in condition for safe operation. This refers to the
condition of the aircraft with relation to wear and deterioration. Such
conditions could be skin corrosion, window delamination/crazing, fluid leaks,
tire wear, etc."
