AC 43.13-1B 9/8/98 subjected to the compression load. An area of grain waviness would indicate a potential compression failure. In all cases the manufac- turer’s inspection data should be followed. g. Moisture Meters are effective tools for detection of excessive moisture content in wood members. An instrument such as this allows the mechanic to insert a probe into the wood member and read its moisture content di- rectly off the meter. A correction chart usually accompanies the instrument to correct for tem- perature and species of wood. Any reading over 20 percent indicates the probability of fungus growth in the member. Moisture con- tent of the wood should be 8-16 percent, pref- erably in the 10-12 percent range (this range is during inspection). Where plywood skin cov- ers the spar and the spar would be inaccessible without removing the skin, the moisture meter probe can be inserted through the plywood skin and into the spar to check the moisture content of the spar. The small holes made by the probe are easily sealed. h. Destructive testing of sample bonded joints whenever a new bond joint is made, a sample joint should be made with the adhesive from the same batch used on the repair and scraps of wood left over from the repair. After curing, the sample joint should be destruc- tively tested to ensure proper bonding of the two wood pieces. Any failure in the bond line indicates a cohesive failure of the adhesive. Any failure along the bond line indicates an adhesive failure, which is indicative of poor bonding. The ideal situation is when wood fi- bers are observed on both sides of the fracture surface. This indicates a failure in the wood, and indicates the bond joint is actually stronger than the wood. 1-30.1-35. [RESERVED.] Page 1-14 Par 1-29PDF Image | AFS-640
