THE SIX SACRED ITEMS THAT DEFINE A MAJOR REPAIR OR ALTERATION.



"Major alteration means an alteration not listed in the aircraft, aircraft engine

or propeller specifications THAT MIGHT AFFECT:

1. W & B

2. Structural Strength

3. Performance

4. Power Plant operation

5. Flight Characteristics

6. Qualities affecting airworthiness or is not done according to accepted

practices or cannot be done by elementary operations."



Notice that it does not have a period after the word “specifications”.

Therefore the idea that if it is a required item for the airplane but is not listed

in the TCDS makes it a major alteration is DEAD WRONG.

Because it also has to have appreciable affect on one or more of the six

items listed above.



Furthermore it does not say that making a repair or alteration better then

original "IS A MAJOR ALTERATION". Clearly then if one is competent in

the English language, by making something better does not necessarily

affect any of the SIX items above.



Ref: FAR 1, “Major alteration” (1), (2), (3). And CAR 18 Major Alteration

(A) & (B).
