Q. A Sefer Torah that is constantly read on Parshas Pinchas and was found to have at least three letters where the ink cracked and fell turning the Sefer pasul, can you just fix the letters erased on that parsha or do you have to check now the complete Sefer Torah?
A. Horav Shlomo Miller’s Shlit’a opinion is that if the Sefer was used mainly to be read on Yom Tov or similar occasions when we read Parshas Pinchas, it is likely that the extended use of that particular parsha created the problem and the rest of the Sefer does not have to be checked, if there was no information that other locations have been affected. However, Parshas Pinchas and other neighboring areas that could have been damaged by the extended use, should be inspected and fixed properly.
