|
|
Term

|
|
Term
| HOW IS THE STRENGTH OF THE AIRCRAFT FABRIC ON AN AIRCRAFT STRUCTURE DETERMINED? |
|
Definition
| AN APPROXIMATE STRENGTH TEST CAN BE MADE WITH AN FAA APPROVED FABRIC PUNCH-TESTER . ONLY WAY TO ACTUALLY KNOW SUFFICIENT STRENGTH IS BY PULL TESTING A 1 INCH WIDE SAMPLE. |
|
|
Term
| WHY ARE SOME PORTIONS OF THE STRUCTURE OF AN AIRCRAFT DOPE PROOFED BEFORE THEY ARE COVERED WITH FABRIC? |
|
Definition
| TO KEEP THE FABRIC FROM STICKING TO THE STRUCTURE AFTER FIRST COAT OF DOPE IS APPLIED. |
|
|
Term
| WHAT IS DONE TO COTTON AND LINEN FABRIC TO PROTECT IT FROM MILDEW? |
|
Definition
| THE FIRST COAT OF DOPE THAT IS USED ON COTTON AND LINEN FABRIC HAS A MILDEWCIDE MIXED IN IT. |
