(1) Inspect 4-inch tape for wear. No more than 0.5 inch wide spanwise or chordwise hole allowed
on trailing edge. No holes allowed on any other surface of tape.
(2) Inspect upper and lower trailing edge of tape for disbonding. No more than 0.25 inch
chordwise width for any spanwise length of tape or 0.5 inch chordwise width for 6 inches spanwise
length along a single piece of tape is allowed.
(3) Inspect for inboard and outboard ends of tape segments for disbonding. No more than 0.5
inch-spanwise or chordwise is allowed.
(4) Inspect for internal disbonding of tape segment. No more than a single disbonding larger than
3.0 inches spanwise and/or 2.0 inches chordwise is allowed. In addition, no more than a total of 6
square inches is allowed for multiple disbonds on a single tape segment. There is no limit to the
number of disbonds per tape segment providing material is not torn.
If damage is discovered and found to be within the above limitations,
do not trim off these damaged areas. Trimming off these damaged areas
creates an increasingly lighter blade and may cause an out of balance
