Actuate the teleflex dables during the inspection. If a chafed electrical cable is found, repair the cable in accordance with paragraph (c) of this AD before further flight.

  (b) Within the next 100 hours time in service after the effective date of this AD, unless earlier compliance is required pursuant to paragraph (a) of this AD, comply with paragraph (c) of this AD.
