Most aircraft companies in the preparation of structural repair manuals will include only those repairs that are common to pressurized or non pressurized aircraft including helicopters.
When the aircraft goes into service and structural problems occur that are not covered in the repair manual the company in concert with the operator will develop a repair procedure. This procedure will be entered into the structural repair manual when it goes into revision (usually every six months). If the repair is serious enough an AD will be issued to all operators to check the specific area to determine if the structure has been compromised. And if so, the repair procedure will normally be included in the AD or, if not the repair procedure will be furnished by the manufacturer under separate cover.
If the structural problem is serious enough the company will provide technical assistance to the operator.
