IN THE AEROSPACE WORLD, THE procurement of spare parts is not always easy and is usually expensive, specially for older aircraft. At some point, when it comes to vintage aircraft, spare parts become rare, or in a worst case they simply don't exist anymore. A historically significant airplane disappears from the airfield and becomes in a best case a static exhibit in the museum. Today, with a help of reverse engineering technology the active life of such an airplane or entire fleet can be extended at a reasonable price.

Now, there is a way to prevent the aircraft from being wrecked and to get them back in the air, even if there are no spare parts available.
