Module 6. Materials & hardware

When does an aircraft fabric covering repair become a major repair?

  • When the repair extends over a wing rib.
  • When the repair extends over three adjacent wing ribs.
  • When the repair extends over two adjacent wing ribs.

Explanation

A localised fabric patch is a minor repair, but once the repair spans the bays of two adjacent ribs it affects a significant area of the load-carrying surface and is classed as a major repair requiring approved data. A repair over a single rib remains minor.

cpster asking:

the answer should be when the repair extends over two adjavent wing ribs..
