When the Construction of an AB Aircraft Ends


THE CONSTRUCTION OF AN AMATEUR BUILT PLANE DOES NOT FINISH WITH THE RECEPTION OF THE PINK SLIP FROM THE DAR.

Normally the guys that put considerable deals of money, sacrifice, efforts, and even joys in the construction of an aircraft, consider the inspection and approval from the DAR -documented in the coveted "Pink Slip"- as the milestone that marks the completion of the construction process.
This is quite not true.

It is one of the most dangerous half lies/half truths. Here's why: "The construction stage ends when the plane is ready to accomplish its purpose, it is to fly".
That the plane is ready  means -more than a legal status- that it is apt, able, prepared, capable. And therefore,  to fly also implies that is safe and consistent to it design intent. 
So, when the construction ends ?

The construction of an Amateur Built Aircraft finishes after it is tested, all squaks are corrected and everything is properly documented in the Pilot Operating Handbook. It is then when we have a finished airworthy airplane!

The Airworthiness Certificate –the Pink Slip– is the way to state that aircraft you built is legally apt to be flown in order to test and establish its operating limits.
Sorry, despite the customary use of: “…is a plane! Received the Pink Slip”, indeed it is not. And as said before, it could be a dangerous half truth. Because it leads to think and act as if it is a reliable, dependable plane.
The real stuff is that it has to be tested, squaks or issues found and corrected. And finally, operating limits defined and established. Then you have a plane!

That’s why testing is so fundamental. It is last step of the construction.
