Paint
A gallon of weighs ? But after all the chemicals and aeromatics evaporate, a gallon of paint on aircraft weighs a couple of ounces

Paint
Well I don't know what paint would have 60% solids
House paint? But automotive paint say blue would Have .03%-.1% titanium dioxide, or say black Which would have .1% carbon black. And at 9.5 lbs a gallon Works out to 155 OZ .01% works out to 1.5 OZ Oops 1.55 OZ now that's for one thin coat, no primer etc |

I could be wrong, but I thought that painters shoot a primer coat on before any color coats. If true that's got to add some weight, probably more than the color coats.

So for all practical purposes part §21.93 does apply just as part §43 applies for the purposes of a condition inspection. Remember your op lims can reference parts of the FARs that would not normally apply. Another example is part §91.205 for night and/or IFR operations. |

update: found this: http://www.paintcenter.org/rj/oct07n.cfm So roughly you'd have to spray 14 gallons to add 40ish lbs. Is that what an average paint job will go through? |
I did explain this to the OP a few days ago. Nowhere can I find a reference that a paint job is considered a major change. Many airplanes get flown to paint shops all over the countries in which they reside and there has never been any discussion in any of the Orders regarding requirements to return to Pahse I testing.
However, I do think a new W&B with a logbook entry is very appropriate and should be considered necessary. Vic |
